Six years later and the BMW 1M is still one of the most hyped and talked about cars ever produced by BMW. And that trend is not likely to end anytime soon. Making 340 hp (at 5,900 rpm) and 332 lb-ft (450 Nm) of torque between 1,500 and 4,500 rpm, the manual-transmission-only sports coupe could hit 60 mph in 4.5 seconds. And thanks to the limited-slip differential, brakes, and suspension components it borrowed from the M3, it is one of the best track cars you can own today. Heck, it even received accolades from Jeremy Clarkson.

For most of us owners, including your truly, the engine was more than enough, even though from time to time we’ve applied some tricks to it. But apparently, that’s not the case for others. This BMW 1M featured here comes with the biggest power upgrade possible. Instead of the stock engine, it uses a genuine M powerplant yanked out of an E60 M5.

BMW-1M-V10

The S85 V10 5.0 liter naturally-aspirated engine makes 507 horsepower, but in the orange beast seen here, it goes up to an astonishing 550 hp.

So what do you do with a car like that? Simple! You take out on the track and drift its heart out.
