The 1M Coupe is arguably one of the coolest sports cars BMW has rolled out in the past few years.

That’s why it still has a large group of followers. In fact, its die-hard fans think that a good part of its charm originates from the original M3, evoked by the lightweight and powerful package, even though BMW – along with the 1M – has come a long way from there.

Still, a small powered turbo BMW is always a recipe that won’t go wrong no matter how hard you try; it was a good idea in 1973 with the 2002 Turbo and the M Division thinks it’s a good idea now, with the M2 almost ready.

Even though the 1M Coupe is now part of BMW’s history, that doesn’t stop tuners from improving its performance figures. But there’s a catch; its limited 6309 production run keeps collectors and purists on their toes, frenetically blaming everyone who dares to modify it from its original guise. And sometimes they do have a point. I mean, what more can you want from the little Bimmer? It already has a twin-turbocharged N54 inline six which develops in stock form approximately 340 metric horses. Moreover, the car comes with a well-balanced chassis in a – fairly – lightweight package.

This doesn’t mean there’s no more room for improvement, and the guys from Ok-Chiptuning proved it with this black example. Under the guidance of the German tuner, the little car went from 340 metric horses all the way to 440 (that’s 434 regular horses). Moreover the torque figure has been…“tweaked” as well, from 500 Nm to 696 Nm, while the electronic top speed limiter was removed.

Mind you, the power upgrade wasn’t done via a tuning box or a simple ECU tuning. Sure, an engine software optimization was performed, but it was part of the modifying process and kit which included several upgraded parts, such as a Wagner Tuning EVO 2 Performance intercooler, Wagner Tuning downpipes, Eisenmann race exhaust and a Sachs performance clutch. Other modifications include monotube H&R coilovers, M-Performance parts and 20-inch Schmidt CC-Line wheels.
