Not long ago, we sampled a tuned-up version of the BMW 335i in the form of the Dinan S1, and in our non-track test, we actually preferred the hot S1 to that of BMW's already good M3 Coupe.
Tuner ATT Autotechnik has put its spin on the BMW 335i Convertible and the simple modifications are enough to give it a different sort of edge over the stock droptop M3. For starters, power has been boosted to 356 horsepower and 388 pound-feet of torque. And while that may be 58 less horsepower than an M3, the ATT example produces 93 more pound-feet of torque out of the twin-turbocharged inline-six engine. We've discussed the joys of turbo thrust and torque power before, and in some cases actually prefer it to larger-displacement, naturally aspirated mills (though the M3's V-8 is one hell of a good engine), so it looks like this steroid-enhanced 335i cabrio might offer more interesting dynamics for everyday driving.
Other changes include a sharp set of twenty-inch wheels and stainless steel exhaust, giving it a more subdued overall appearance than a comparable M3. Like the Dinan, we can easily see the Doppelturbo-Cabriolet being a more interesting steer than the M-badged Bimmer on the street, but as a track performer, it's hard to say.
