BMW connoisseurs will be well aware of the rich tradition the suffix “ti” holds in the history of the Bavarian auto manufacturer. Back in the 1960s and 1970s, the abbreviation – which stands for “Turismo Internazionale” – was used to indicate the most powerful models in the BMW 02 series, namely the 1600 ti and the 2002 ti. BMW did more than just add another letter with the 2002 tii: the “Turismo Internazionale Iniezione” variant was powered by a 130 hp 2.0 liter four-cylinder engine with a Kugelfischer mechanical fuel injection system.

By launching the new 128ti (F40) hot hatch a few weeks ago, BMW breathed new life into the “ti” suffix after decades spent mothballed – and, just like in the wild 70s, a 2.0 liter four-cylinder engine packs a punch under the bonnet of this red-hot compact. However, the engineers at dAHLer competition line thought they could still squeeze more out of it, keeping true to tradition – and their 128tii (F40) DCL dAHLer competition line is a major step up when it comes to driving dynamics!

The Swiss BMW tuning specialists boosted the four-cylinder turbo engine (B48A20M1) from the factory-set 195 kW (265 hp) and 400 Nm up to 230 kW (313 hp) and a maximum torque of 500 Nm. In fact, they could have pushed these figures higher still, as test bench runs proved during the development phase. However, in fine-tuning their 128tii, Christoph Daehler and his team placed greater emphasis on helping the F40 deliver its power in a harmonious, controllable manner rather than maxing out the numbers on paper, which ensures “clean” handling from the front-wheel drive. As with all dAHLer competition line projects, the performance enhancements of course have been WLTP-E6d-temp-tested and homologated for the EU and Swiss markets – including TUEV approval, even with the optional Eventuri carbon fiber intake system.

The twin-tube exhaust built by dAHLer from high-grade stainless steel has also been homologated for the EU and Swiss markets and, thanks to its CAN bus-controlled exhaust valves, still emits a deep roar from its ceramic-coating dÄHLer tailpipes, which have an imposing diameter of 114 millimeters.

We also have to mention the exquisite way the 128tii (F40) “DCL dAHLer competition line” sits on the road! Thanks to a performance coilover suspension built by dAHLer, which features adjustable compression and rebound damping – as well as height adjustment, of course – the BMW sticks to the road like a piece of gum. A set of sport springs specifically tailored to BMW’s electronic damper control (EDC) system is also available as an alternative. Naturally, both suspension upgrades have received TUEV approval.

The 128ti leaves the factory equipped with a stable brake system. The multi-piston calipers in this type of performance brake system take up a lot of space, but the dAHLer CDC1 FORGED ultra-lightweight rims have been specifically designed to accommodate them. The rims measure 8×20″ and sit in the 128tii’s wheel wells along with Michelin Pilot Sport 4 S tires (245/30ZR20).

The exterior design of the 128tii (F40) DCL dAHLer competition line is rounded off with wing-mirror housings in keeping with the snappy BMW M look, which also hold TUEV approval.

The passenger compartment has also been upgraded by dAHLer competition line, with soft foot mats in the foot wells and own-brand aluminum pedals set to be launched soon.

One thing’s for sure: this pocket rocket more than lives up to the name “tii”!
