By most measures the BMW M2 is quite a pokey piece of kit at its $51,700 price point. Not only can it defeat the mightiest 350 hp+ all-wheel-drive hot hatchbacks in conditions that don't entirely suit its rear-wheel-drive layout, but quite a few critics have even compared the M2 favorably against the larger, pricier and more powerful M3 and M4. As with many things in life, though, there are a handful out there who aren't satisfied with what they already have. That's why Swiss tuning firm Dahler Design und Technik turned the junior M-car into a true road rocket.

For many people, simply replacing the standard M2's 3.0-liter turbocharged six-cylinder engine with the BMW M4's identically-sized 424-hp engine (as Dahler has done here) would be mad enough. But the Swiss firm hasn't stopped there. Through an array of tweaks and upgrades this engine now produces 540 hp and a very meaty 538 lb-ft of torque. As a result, the Dahler-tuned BMW M2 has some impressive performance stats to its name. The 0-60 mph sprint can reportedly be cracked in under four seconds, and the top speed is claimed to be in excess of 200 mph. How Dahler hit such speeds is anyone's guess, though we imagine a journey over the Swiss border into Germany and a speed run on the autobahn played a crucial part in that...

Throwing ridiculous amounts of power at the smallest M car on sale today isn't all that Dahler has done to the BMW M2, however. On the contrary, the firm's actually done a decent amount of work to ensure the car can actually control the extra 175 hp and 195 lb-ft of torque it has. The subtle lip and trunk lid spoiler helps keep the car planted at higher speeds, and the 18-way adjustable coilovers ensures the Dahler M2 will remain equally secure in the twisties. And to further ensure this barmy BMW can be brought back to a halt after hitting 200 mph, Dahler's also installed its own braking system behind the spokes of the new 21-inch alloy wheels. Needless to say, we'd love to take this powerhouse of a BMW M2 out for a spin one day.
