PORSCHE FACTORY TEAM PREPARES TO START LE MANS 24 HOURS
- After an absence of 16 years, Porsche once again returns to the top LMP1 category at Le Mans
- The 24 Heures du Mans is arguably the world’s toughest sports car race
- Race starts at 15:00 on June 14 around the world-famous 13.6 km circuit – Eurosport will follow the race in satellite TV
- Porsche is fielding its most innovative race cars ever – the new 919 Hybrid – in LMP1 class
- Driver line-up of factory team includes Mark Webber, former Red Bull Racing F1 ace, and Marc Lieb, who set the fastest production car lap record around the Nürburgring in the 918 Spyder
- The iconic 911 RSR competes in the GT category, looking to repeat last year’s class victory
With a podium finish at the start of the 2014 World Endurance Championship (WEC) season at Silverstone and pole position in Belgium at Spa-Francorchamps, Porsche has progressively made its way back into the premier league of sports car racing this season.
This represents a successful start for the newly-founded factory Porsche Team, which in the light of the brave innovations in the new 919 Hybrid was not a foregone conclusion. Such technological breakthroughs herald a new era in the WEC and also at the 24 Hours of Le Mans. The racing car is a technology platform and test laboratory for future series production road cars. No other race car on the WEC starting grid has such an efficient and complex hybrid system as the new Porsche.
The two Porsche 919 Hybrid cars with start numbers 14 and 20 will be driven by two trios of drivers: Romain Dumas (France), Neel Jani (Switzerland), Marc Lieb (Germany) and Timo Bernhard (Germany), Brendon Hartley (New Zealand), Mark Webber (Australia). These six world-class drivers have between them a total of 37 appearances at Le Mans. Despite being a record holder at Le Mans with 16 overall victories, this year the sports car manufacturer has no recent experience of racing at the top LMP category to benefit from. For the first year of the company’s LMP1 project, the target is to get one of the fast Porsche 919 Hybrids to the finish line at the French 24 hour marathon.
Quotes before the race
Fritz Enzinger, Vice President LMP1: “Porsche is facing the biggest moment of the LMP1 project – its first start in the top category at Le Mans in 16 years. Whatever the results, we have successfully completed a lot of stages to get here. Above all, we have established a strong, innovative engineering team in the Porsche Development Centre in Weissach. The new know-how generated in-house by the great efforts of all those involved is something that no one can take away from Porsche. The pole position in Spa showed that the Porsche 919 Hybrid is fast, and, as newcomers, we earned respect for this achievement. I am very proud of this young team, which is as competent in its technology as it is in its drivers. I wish each individual the best of luck and success in this marathon.”
Alexander Hitzinger, Technical Director LMP1: “The challenge of developing a car for Le Mans was always to build a fast yet durable car. The constraints of the new race regulations have made this task even more difficult, but fascinating as well. Even in areas that were routine for the competition, we had no experience whatsoever. Nonetheless, we chose the boldest solution for our drive concept, because it offered the best future potential. In the pre-testing period, the aerodynamics that were once again modified to achieve lower air drag for the Le Mans event proved themselves, as did advanced developments that enhanced durability. The Porsche 919 Hybrid is our first LMP1 race car design. It is fast – but not all of its potential has been realised yet; that is the reality.”
Andreas Seidl, Team Principal LMP1: “The operating task for a Le Mans team is enormous. We had to build an organisation with new personnel from the ground up. They are all excellent people. But even a hundred top soloists must first learn to play together as an orchestra. Responsibilities, communication, procedures, manual tasks – everything must mesh together perfectly. We have only competed in two races so far: in Silverstone and in Spa-Francorchamps. Everything went remarkably well. Our training was intensive. The team will have carried out 1,573 pit stops up to race week at Le Mans. We have also tested at night. Nonetheless, we have not yet experienced the stresses of a 24 Hour race as a team. Everyone is looking forward to this challenge.”
Drivers, 919 Hybrid number 14
Romain Dumas – 36, France.
(13 races: overall victory 2010, 3rd place overall 2007, class victory GTE 2013, 2nd place GT class 2001 and 2002, 3rd place GT class 2004)
“Le Mans is the most famous and toughest race in the world, and it is even more special for me as a Frenchman. I have been driving here since 2001, and I also lived here. In 2010 I won the race; I would love to repeat that one day – together with Porsche. So many people have been anticipating this return to LMP1 by Porsche. It makes me very proud to be one of the six drivers here. I have wanted to be with Porsche ever since my father put me in a 962 as a child. My favourite part of the track is the Porsche Curves. Not because of their name, but because they are so quick and difficult. When you race down the Hunaudières at 330 km/h at night – all by yourself in your own world – you live a dream. You see and smell what is happening around the track. But you have to remain focused. We want to get to the finish line.”
Neel Jani – 30, Switzerland.
(5 races since 2009)
“Le Mans is living motorsport history. That is more true of Porsche than with any other brand. To be part of the return to the top class after 16 years is a dream come true for me. Most racing car drivers would agree. It is a great honour, but also a tremendous responsibility. My best result at Le Mans was in 2012 when I finished fourth with a privateer team. I knew I could only improve on that result in a good factory team. Now I have reached that point. But, regardless of which class or which car, this race stirs up an emotional feeling. I will never forget my first time racing at night; it was awesome. Yet, it is important to block out all of that and concentrate on doing your best – for yourself and your team-mates. We want to be competitive in our first year.”
Marc Lieb – 33, Germany.
(8 races: class victory GTE 2013, class victory GT2 2010, class victory GT 2005, 2nd place GT class 2003)
“Porsche took me on board in 2000 when my bank account was empty and the prospects for my single-seater Formula racing career had almost run out. It means a lot to me to now be part of a return to the top class, especially since we have this incredible technology that our engineers have created for the 919 Hybrid. Starting in the LMP1 class changes your perspective entirely compared to racing in the GT categories. You look less in the rear-view mirror and more at the cars out front that you are going to lap. Radio contact with the pit crew is also much more intensive to achieve efficient energy usage. The racing is incredibly tough for everyone involved. Whenever I won class victories, the most enjoyable thing for me was to look down from the podium and gaze at the tired but happy faces of the mechanics.”
Drivers, 919 Hybrid number 20:
Timo Bernhard – 33, Germany.
(7 races: overall victory 2010, class victory GT 2002, 2nd place GTE class 2013, 2nd place GT2 2005)
“In my first start for Porsche in 2002, Le Mans was stunning. And people always asked me: When will you return to the top league? I was involved with the building of the LMP1 team right from the start, and in 2013 I drove at the roll-out, then did testing and development work. The entire time I had the big goal in mind; I can hardly express how much I am ready for it now. The week leading up to the race will still be intensive, right up to the starting ceremony. I always found it satisfying to be the starting driver, and to finally close the door after all the pre-race show was over. And then at some point on this long circuit you find a very special rhythm. Especially at night when everything gets even faster, and when it might drizzle or rain … It is indescribable; there is a certain magic to it.”
Brendon Hartley – 24, New Zealand.
(2 races since 2012)
“For me, Le Mans is my whole passion. I have the feeling that racing here fulfils the entire reason I climbed into a kart for the first time at six years of age. To now start as a Porsche factory driver, for the greatest sports car icon is like a dream. And then there is this special project with technology that never existed before. Hybrid systems, all-wheel drive, intuitive operating systems – the Porsche 919 is fantastic. Sometimes I can hardly believe that I have been chosen to sit in this car. I especially like Le Mans at night; that is the best. The lights fly past you, and everything feels a lot faster. You nearly get tunnel vision – that is when the cockpit is the perfect place for me. I also have a sporting score to settle at Le Mans.”
Mark Webber – 37, Australia.
(participated 1998 and 1999 at Le Mans but not in the race; 9 Formula 1 victories)
“To return to Le Mans is emotionally very special for me. Le Mans stands for endurance, trial of man and machine, an incredibly long day, often with changing conditions and, above all, there is the teamwork. Naturally, I want to leave here with happier memories than previously, which should not be too difficult. And, of course, I want to win this race sometime. We have a fast car with fantastic technology. I also like the seating position, tucked behind the windscreen, and I am looking forward to the night-time driving at Le Mans. The team is still very young, but the bonding in the team has been very quick. If we were to come up with a good result in our first year that would be a massive statement for Porsche as a brand.”
Porsche keen to repeat last year’s victory in GT class at Le Mans
- Porsche Team Manthey tackles the Le Mans 24 Hours with two 911 RSR in the GTE-Pro class
- With a rear-mounted 470 hp flat-six engine, the ‘Type 991’ RSR is the latest example of the iconic 911 coupe participating in GT sports car racing
- Porsche customer race teams will also campaign the RSR
- US movie star Patrick Dempsey returns to Le Mans with Porsche, driving a 911 RSR for the Dempsey-Proton Racing team
It was a debut made to order. At its first ever outing at the 24 Hours of Le Mans last year, the Porsche 911 RSR brought home a double victory. At the 82nd edition of the world’s most famous long distance sports car race, contested on the Circuit des 24 Heures on 14/15 June, Porsche Team Manthey will again field a pair of 911 RSR in the GTE-Pro class.
Taking up the challenge alongside the factory squad, Porsche customer teams from Europe and America again contest the GTE-Am class, in which Porsche was also victorious last year. The classic event in provincial France, where Porsche is chronicled as the most successful manufacturer with 16 overall victories, is regarded as the highlight of the Sports Car World Endurance Championship (WEC).
First contested in 1923, the 24 Hours of Le Mans is the toughest automobile race in the world and represents the greatest challenge motorsport has to offer. What makes this classic so unique is also the 13.65 kilometre Circuit des 24 Heures, one of the oldest and fastest race tracks in the world with 38 corners and the legendary five-kilometre long Mulsanne straight. Almost 75 percent of a lap is driven at full throttle.
Double points are awarded for round three of the sports car World Endurance Championship (WEC) at Le Mans. Tackling the GTE-Pro class in the number 91 Porsche 911 RSR are Porsche factory pilots Joerg Bergmeister (Germany), Patrick Pilet (France) and Nick Tandy (Great Britain). Sharing the #92 cockpit are their works driver colleagues Marco Holzer (Germany), Frédéric Makowiecki (France) and last year’s winner Richard Lietz (Austria).
Customer teams take on the GTE-Am class with a pair of 911 RSR. For the Dempsey Racing-Proton outfit, Patrick Dempsey (USA) and Joe Foster (USA) join forces with Porsche works driver Patrick Long (USA).
Christian Ried (Germany), Porsche junior Klaus Bachler (Austria) and Khaled Al Qubaisi (Abu Dhabi) compete for Proton Competition.
The customer squads IMSA Performance Matmut and Prospeed Competition each bring two Porsche 911 GT3 RSR in last year’s spec to the start. IMSA Performance Matmut has contracted an all-French driver line-up with Erik Maris, Jean Marc Merlin and Eric Hélary as well as Raymond Narac, Nicolas Armindo and David Hallyday.
Taking on the challenge for Prospeed Competition are Cooper MacNeil (USA), Bret Curtis (USA) and Jeroen Bleekemolen (Netherlands) as well as Frenchmen Francois Perrodo and Emmanuel Collard.
The Porsche 911 RSR
The Porsche 911 RSR which Porsche has campaigned in the Sports Car World Endurance Championship since 2013 is based on the seventh generation of the iconic 911 sports car. At its race debut last year the 470 hp winning racer from Weissach scored a brilliant double victory at the 24 Hours of Le Mans.
For 2014, the 911 RSR received improvements in many areas. In addition to winning the WEC season opener at Silverstone, this racer has also clinched victories at the long distance classics at Daytona and Sebring. Through the balance of performance ruling, the 911 RSR for Le Mans must now weigh 25 kg more than last year’s contender, with the engine air intake restrictors as dictated by the rules also reduced from 29.6 to 29.3 millimetres diameter.
Free practice on the Circuit des 24 Heures is held on Wednesday, 11 June, from 16.00 to 20.00 hrs, followed by the first qualifying session from 22.00 hrs to midnight. Two more qualifying sessions follow on Thursday, 12 June, from 19.00 to 21.00 hrs and from 22.00 hrs to midnight. The start flag for the 24 hour pursuit drops on Saturday, 14 June, at 15.00 hours. The 56-strong field is flagged off by ex-Formula 1 World Champion Fernando Alonso.
Eurosport International and Eurosport 2 alternately broadcast the complete race live. The last two hours of free practice as well as the three qualifying sessions and the warm-up are also televised live. Also aired during the week are various programmes highlighting the world’s most famous long distance race with news, interviews, portraits and background reports. Detailed TV information is available via eurosport.com.
Quotes before the race
Hartmut Kristen, Head of Porsche Motorsport: “Le Mans is the highlight of the year. For our teams and drivers this race represents an exceptional challenge – and we’re feeling highly motivated and very well prepared. After our double victory at the season-opener in Silverstone, our car now has to carry 25 extra kilograms of ballast and the diameter of the two restrictors is now 0.3 millimetres smaller than last year’s. When considering the additional changes made, as against 2013, at one or the other competitor one has to question to what extent is the Balance of Performance actually balanced. We feel it is a matter of utmost urgency in the spirit of the sport to find a regulation for the classification of vehicles where you don’t have to fear being punished for a good performance, like what happened to us after Silverstone. Nevertheless, we’ll work extremely hard to do a good job at Le Mans – just like last year.”
Drivers, 911 RSR number 91
Joerg Bergmeister: “I’ve raced at Le Mans since 2002 and it’s a fantastic feeling to be back again this year. It’s the season highlight for me. This race has a very special atmosphere and it’s always incredibly demanding. More than anything I enjoy the extremely fast corners, they’re the most fun. Last year we came second behind our team-mates and I wouldn’t mind at all if we switch positions this year.”
Patrick Pilet: “Le Mans is a very special race, especially for me as a Frenchman. It’s always an incredible feeling to go racing on such an extreme circuit in front of so many fans. Aside from the Indy 500 and the Monaco Grand Prix, Le Mans is the greatest race on Earth. We are well prepared and our 911 RSR is a strong contender, especially on the long straights. It would be fantastic if we could turn this into a win. We were so close last year.”
Nick Tandy: “Ever since I began racing for Porsche at Le Mans in 2010 it has been my goal to secure a podium spot here. You only get this chance once a year and I’ll do everything within my power to make it happen. For a race driver, Le Mans is a magical place. Even when you arrive in the paddock you get a sense of the great history. And the Circuit des 24 Heures is something very special with its unique combination of race track and normal country roads. It’s an honour for me to drive again for Porsche at Le Mans this year.”
Drivers, 911 RSR number 92
Marco Holzer: “At my first race in Le Mans in 2010 we managed to achieve a podium finish with third place. When I think back to the cheering crowds at the award ceremony it still sends shivers down my spine. I’d very much like to experience this feeling again and our chances don’t look too bad. We have a great car and a strong team behind us. But in Le Mans you can’t afford to make one mistake. You have to be totally focussed otherwise you can forget it.”
Frédéric Makowiecki: “As a Frenchman you simply have to race at Le Mans. And you want to win. Your family is watching at the track, your friends are there supporting you. This makes it hugely motivating to achieve everything you’ve set out to do. As a child I dreamed of Porsche. I launched my racing career with Porsche. If I could now win Le Mans with Porsche, well that would just be the best thing in the world. But first we have to face 24 gruelling hours where pretty much anything can happen.”
Richard Lietz: “I have many wonderful memories of Le Mans, especially my wins in 2007, 2010 and 2013. It’s the greatest race in the world. I love it. If I couldn’t be here as a driver, I’d buy a ticket and watch the race as a spectator. Earlier, only victory in Le Mans counted. Since 2013, it has become part of the sports car World Endurance Championship which means that if you can’t win then you have to make sure you bring home as many points as possible. The connection between Porsche and Le Mans is pure racing fascination. Getting the chance to compete at Le Mans for Porsche, the most successful manufacturer in the history of this race, is motivation enough. You automatically do your absolute best to win.”
Drivers, 911 RSR number 77
Patrick Long: “Le Mans is always a huge challenge. Everyone wants to win, regardless of the category they’re contesting. I’m really looking forward to racing with Patrick Dempsey and Joe Foster and helping the whole team to fulfil their dreams at Le Mans. Last year we narrowly missed out on a podium spot. This time we’re determined to make it.”
Porsche at Le Mans: Facts and figures
- With 16 overall victories, Porsche is the record holder at Le Mans.
- The first Porsche overall victory dates back to 1970 (Hans Herrmann/Richard Attwood in a 917 KH Coupé), and the last victory to date was on June 7, 1998 (Laurent Aiello/Allan McNish/Stéphane Ortelli in a Porsche GT1).
- According to the official archives, 812 Porsche cars have raced at Le Mans and that, too, is a record.
- The fastest qualifying lap was driven by Hans-Joachim Stuck in 1985 in a Porsche 962 C (average speed 251.815 km/h). That record will likely stand for eternity, since chicanes installed in 1990 now break up the long Hunaudières straight.
- The longest race distance was covered by Timo Bernhard/Romain Dumas/Mike Rockenfeller in 2010 in their overall victory for Audi, a total of 5,410.713 km (397 laps, average speed 225.45 km/h).
- The Porsche 919 Hybrid car numbers 20 and 14 stand for the year of our return.
- In qualifying (Wednesday and Thursday until midnight), every driver must run at least five laps in the dark. While WEC rules call for averaging the two fastest laps of two drivers (i.e. the mean of four lap times), the classic Le Mans method is to simply take the fastest lap driven with the car.
- The Le Mans night is one of the shortest of the year: the sun sets on Saturday at 9:55 pm, and it rises again on Sunday at 5:53 am.
- In normal racing mode (without any Safety Car periods), the Porsche 919 Hybrid must refuel every 13 to 14 laps.
- Refuelling and wheel changing may only be made sequentially, not at the same time. Only two mechanics may work simultaneously when wheel changing. That takes a lot longer than in Formula One, for example.
- Drivers are normally only changed when new tyres are needed.
- Two fuel tank fills with one set of Michelin tyres are the absolute minimum; three should be standard, and sometimes it might even be possible to do four – an open issue and a tremendous challenge for the drivers.
- During the race, no driver may drive for more than four hours within a six-hour period. No driver may drive for more than 14 of the 24 hours.
- Due to the length of the circuit, there are three Safety Cars at Le Mans.
- The equipment taken to the track – in addition to the two race cars – includes a spare chassis, six engines, five front gearboxes, five rear gearboxes, six front wings and six rear wings, 80 rims, over 100 radios and headsets.
- The amount of electrical energy that a driver can use for what is known as boosting is limited. The Porsche 919 Hybrid may consume exactly 1.67 kilowatt hours (kWh) of electricity on each 13.629 km lap.
- In 2013, the Le Mans victor completed 348 laps. Over this distance, the 919 Hybrid would generate and utilise 581.2 kilowatt hours (kWh) from its energy recovery systems – an amount of electrical power that would light a 60-Watt incandescent light bulb for a full 9,687 hours. Or expressed differently: this amount of energy would power the new Volkswagen e-Golf, which is currently the most energy-efficient electric car in the compact class, over 4,576 kilometres – enough to drive one-way across the USA from New York to Los Angeles.
- All in all, there is even more honour and glory to be won at Le Mans: twice as many points are awarded than in the other seven races for the World Endurance Championship (WEC) that are each six hours long.
- In the WEC standings, the Porsche team with 36 points is currently behind Toyota (84) and ahead of Audi (28) after two of eight races.
- The Porsche 919 Hybrid was designed and built at the Development Centre of Porsche AG in Weissach. 230 team members work there.
- The core team of Porsche for LMP1 racing at the race circuit in Le Mans consists of 86 team members (engineers, mechanics, team management). Add to that personnel from communication and marketing, sponsoring and driver support.
- For Le Mans week, supplies include well over 1,000 team shirts and other clothing.
- The shopping list for food and refreshments for the team and the media hospitality area include: 50 boxes of salad, 50 kg of strawberries, 300 melons, 1.2 tonnes of meat, 500 kg of fish, 600 kg of noodles, 2,000 eggs and 1,100 loaves of bread.
- While most of the team members catch some sleep during the night of the race whenever they have time and space, the drivers have beds in containers located behind the pit. It is impossible to get a quiet rest, sleep from exhaustion is more likely.
- The organiser, the Automobile Club de l’Ouest (ACO), expects over 250,000 spectators at the race.
INNOVATIVE PORSCHE POWER FOR LE MANS MARATHON
Under the skin of the 919 Hybrid, the most complex Porsche race car ever
- Designed and developed in-house by Porsche engineers at Weissach to compete in the top LMP1 category of World Endurance Championship (WEC) and Le Mans
- The Porsche 919 Hybrid is entered in the ‘6-megajoule’ class, where the rules dictate that the 500 hp+ petrol engine must consume just 4.78 litres fuel per lap at Le Mans
- Complex hybrid drive system features highly innovative recuperation of thermodynamic energy from exhaust gases
The return of Porsche to the top LMP class of the World Endurance Championship (WEC) presents significant challenges. Firstly, the new 919 Hybrid is the most complex racing car the Stuttgart sports car manufacturer has ever built. Secondly, unlike the competition, Porsche does not have experience or data to refer to from previous years’ racing at the top level (outside the GT category). And, thirdly, Porsche used its own engineers develop the prototype in its newly-set up LMP1 racing team – a significantly more difficult, but in the long-term more promising, route than buying existing components from other companies. In this endeavour, Technical Director LMP1 Alexander Hitzinger and his team are pursuing a proven path that has a long tradition at Porsche: finding solutions which may benefit series production customers in the future.
The search for the optimum energy conversion efficiency – ie the best possible ratio between supplied and utilised energy – is massively influencing every aspect of the Porsche 919 Hybrid, the aerodynamics of the Le Mans race car, as well as the weight-optimised individual components. However, the highly advanced energy recuperation and drive systems are two of the outstanding features in this regard.
The revolutionary new technical regulations of the WEC for the 2014 season gave the specialists at Porsche a great deal of freedom. A limiting factor for the performance of the car is primarily the amount of fuel available per lap. This approach makes energy efficiency a primary factor. Meanwhile, a hybrid system is also a pre-requisite for the factory cars starting in the LMP1-H category. The rule-makers have left the type and method of storing the retrieved energy up to the constructor as well as the choice of engine design and the displacement.
The 919 generates energy for more than 4,500 km in 24 hours
The amount of electrical energy each driver can use per lap at Le Mans delivered as a boost is limited. The rules specify four classes of energy levels ranging from 2 to 8 megajoules (MJ). Porsche has registered the 919 Hybrid for the 6 megajoule category, which means that the LMP1 prototype can use exactly 1.67 kilowatt hours (kWh) of energy per 13.629 km (8 mile) long lap on the “Circuit des 24 Heures”, since 3.6 megajoules is equivalent to 1 kilowatt hour (kWh). But what does this mean in real terms?
In 2013, the Le Mans winner covered 348 laps. Calculated over the same distance the new 919 Hybrid generates and uses 581.2 kilowatt hours (kWh) – an electric output which would run a 60 watt light bulb for a staggering 9,687 hours. Or in other words, with the energy the LMP1 Porsche prototype recuperates during the Le Mans race you could cover 4,576 km in the most efficient electric car that is currently available in the compact class, the new Volkswagen e-Golf – which would take you across the USA from coast to coast, from New York to Los Angeles.
Thermodynamic energy recuperation makes its mark
“The recuperation of kinetic braking energy at the front axle has great potential with the axle load being dynamically shifted to the front when you brake, so a system that exploits this was a logical step,” explains Alexander Hitzinger. “In favour of this solution we gave up a KERS on the rear axle. If you start with a naturally aspirated engine, KERS is the only option you have. But using turbocharging gave us another option, which is why we opted for using the energy from exhaust gases from the turbocharger.”
The complex hybrid system in the new Le Mans prototype with its highly innovative recuperation of thermodynamic energy from exhaust gases is unique in the WEC. This principle basically uses an extra turbine generator unit instead of what is called the wastegate. This valve normally allows excess energy from exhaust gasses, that are not required to drive the compressor, to escape into the atmosphere.
Porsche utilises this excess energy from exhaust gases; it drives a second turbine, which in turn drives a generator that produces electrical energy. The new technology recuperates energy that has always been lost in other systems. This use of energy from exhaust gases makes the Porsche 919 Hybrid the only car in the field that recuperates energy not only when it brakes but also when it accelerates. Both systems direct kinetic and thermal energy converted into electrical energy back to a liquid cooled lithium ion battery.
Same driving performance, 30 per cent less fuel consumption
Porsche has also made its own way in its method of storing electrical energy. Here the same premise was applied, so, instead of drawing on less effective but readily available systems, Porsche decided to exploit promising technologies and in this case liquid cooled lithium ion batteries.
“Developed in co-operation with Porsche Engineering,” stresses Hitzinger, “so this know-how benefits future hybrid vehicles.” Hitzinger also looked into flywheel storage and super-capacitors, so called ‘ultracaps’, but found lithium ion batteries to be the best compromise. “But only if,” he adds, “the right cell technology is available to provide a very high power density with relatively high storage capacity.”
To achieve this Porsche puts its faith in battery cells from its partner A123 Systems.
The approach Porsche has used for the combustion engine is just as unique. The newly-developed V4 turbo with two litre engine displacement and direct injection – a system that is atypical for Porsche – is a pioneering example of downsizing. The four-valve engine represents the ideal combination of low weight and compact size with structural rigidity and high power output. Since Porsche is starting in the 6-MJ class with the 919 Hybrid, the rules allow the petrol engine with over 500 hp a consumption of only 4.78 litres per lap in Le Mans. The more powerful the recuperation system, the less fuel may be burnt. Although the driving performance is the same, the permissible amount of energy is 30 per cent lower than last year.
Le Mans: extreme technology solutions for specific challenges
This year’s calendar for the FIA WEC (World Endurance Championship) involves eight races. After the six-hour opening races in Silverstone in the UK and the “Ardennes roller-coaster” of Spa-Francorchamps, the third World Championship race is truly outstanding. The legendary 24 Hours of Le Mans is both the highlight of the season and a unique challenge. Much of the 13.629 km “Circuit des 24 Heures” track – nine kilometres of it – runs over closed country roads which are usually open to commuters and heavy goods vehicle, leaving behind grooves in the surface. Also characteristic for Le Mans are long straight straights. The LMP1 factory cars reach speeds significantly higher than 320 km/h (200 mph) several times during each lap, and twice they have to decelerate to urban traffic speeds at slow turns – by day and night – while the engines are on full throttle for about 70 percent of the lap.
The hard braking phases and prolonged powerful acceleration around the Le Mans circuit led Porsche to develop the temporary all-wheel drive 919 Hybrid with its kinetic and thermodynamic energy recuperation systems for these specific conditions. The finely balanced aerodynamics of the vehicle also play a decisive role in making the 919 Hybrid competitive in Le Mans. The resulting downforce values guarantee excellent speeds in fast corners, such as the ‘Porsche Curves’. Opposed to this are the lowest possible air resistance values so that the 919 Hybrid can reach maximum speeds over the long straights.
After the racing festival in the French Sarthe department the WEC is taking a three-month summer break, and then it will leave Europe for the rest of the season. The programme includes five more six-hour races: USA (Austin, 20 September), Japan (Fuji, 12 October), China (Shanghai, 2 November), Bahrain (Sakhir, 15 November) and Brazil (Sao Paulo, 30 November).

In what is the highest profile event in the 12 year history of the Carrera Cup GB, drivers will take to the awesome eight mile (13.6 km) track for a 45 minute race during the final build-up to the start of the legendary 24 Hours. The event has even greater significance as Porsche returns to compete at the top LMP1 category of sports car racing in the World Endurance Championship this year.
Heading the Carrera Cup GB field is Championship leader Michael Meadows (Samsung UHD TV Racing) and he is determined to make his mark in the race by challenging the best of the very strong entry from Carrera Cup France. Meadows heads to Le Mans with a 16 point Championship lead, but admits that the overall result is more important this weekend than Championship points.
Leading the chase of Meadows in the title race is Carrera Cup GB Scholarship racer Josh Webster (Redline Racing) and he has shown mighty form in his opening races in the rear-engined, 460hp 911 GT3 Cup. However, a major contender for overall victory re-joins the Carrera Cup GB as Ben Barker heads up the Parr Motorsport squad. You can be certain the Porsche Mobil1 Supercup and GT racer will be right at the head of action in this special race.
Adding tremendous strength to the Pro field are Victor Jimenez (Redline Racing), Paul Rees (In2 Racing) and young Jake Hill, who returns to the Championship with In2 Racing after an impressive debut at Brands Hatch in March. All of them are contenders for the overall podium.
The Pro-Am1 category is headed by Irishman Karl Leonard (Team Parker Racing) and he should be the benchmark. However, Rob Smith (Redline Racing), Graeme Mundy (In2 Racing) and Championship newcomer Bill Cameron (Team Parker Racing) are all out to make their mark on this famous track.
The Pro-Am2 battle promises to be just as tough as category leader Steven Liquorish (Team Parker Racing) resumes his sporting rivalry with Peter Kyle-Henney (Parr Motorsport) and Will Goff (In2 Racing). Racing at Le Mans is a major ambition for all three drivers, so it will be a very special weekend for them.
Renowned journalist, Chris Harris, will also line-up on the starting grid in France, driving the Carrera Cup GB guest car with RedLine Racing. The opportunity for Chris to take part in this sensational race is being supported by specialist professional and personal insurance providers Ellis Clowes, which will be providing full insurance along with personal accident cover for Chris during the whole event.
Meanwhile, running alongside the Carrera Cup GB field will be three drivers from the Porsche GT3 Cup Challenge. Peter Smallwood (Parr Motorsport) heads the entry and will travel from his new home in Canada for the race. He will go up against Guy Riall (Redline Racing) and Tom Hallissey (ASK Racing) in this unique opportunity to race at one of the world’s biggest race meetings.
After qualifying on Thursday (12 June) at 17.30, round seven of the Carrera Cup GB will start at 11.15 on Saturday (14 June).
The Porsche Carrera Cup race at Le Mans will be broadcast live on Motors TV at 11.15 (CET). While hundreds of thousands of fans will see the action live at the French track, the Motors TV coverage will allow fans back in the UK and right across Europe the chance to watch this very special race as it happens.
Special star in Porsche AG guest car
Laurent Aiello from France teamed up with Alan McNish and Stéphane Ortelli in 1998 and clinched the most recent overall victory for Porsche at the Le Mans 24 Hours. The trio won the world’s most famous long distance race at the wheel of the 911 GT1 ‘98. Now, the Frenchman celebrates his comeback with Porsche on the Circuit des 24 Heures. Behind the wheel of a 911 GT3 Cup entered by Porsche AG, he tackles the Championship rounds of the British and French Porsche Carrera Cups prior to the start of the 24 Hours.
For Laurent Aiello and the 200,000 spectators around the 8 mile long circuit, this will undoubtedly evoke a very special feeling of déjà vu. His 911 GT3 Cup not only features the same livery as the victorious GT1 of 1998, but also flies the same starting number 26. And the race engineer who looks after the technical aspects of this guest appearance stood behind the pit wall when he scored his overall victory; Porsche Meister Roland Kussmaul.
Laurent Aiello is one of the most successful touring and sports car drivers in France. In addition to his Le Mans victory, he has also won Touring Car Championships in Germany, Great Britain and France. His last major victory was in 2002 when he took home the German DTM title. With his guest appearance at Le Mans, he follows in the footsteps of many successful race drivers who have taken up the gauntlet in the famously cut-throat Porsche single marque Cup racing Championship.
Last year, for example, nine-time World Rally Champion Sébastien Loeb and five-time Le Mans winner Emanuele Pirro pitted themselves against the 911 GT3 Cup specialists in the Porsche Mobil 1 Supercup.
