Just a week ago, the first official images of the BMW M2 CS leaked online. Now, the boys from Bavaria have made it official. Lighter and more powerful than the standard M2, it features an engine derived from its big brother, the M4.

Whereas the standard M2 gets a tweaked 340i engine, the M4-based mill in the M2 CS gets an extra turbo and special tuning. It now makes 410 PS and a whopping 550 Nm of torque from its 3.0-liter, twin-turbo inline-six. It's 15 PS less than the M4 but it gains a substantial 40 PS more than the lesser M2. Torque gets a significant bump too from 465 Nm to 550 Nm. Initially, it was thought that the M2 CS will only come with a dual-clutch transmission but BMW has gone on record saying it can be specified with a six-speed manual.

Factory performance figures claim the car can hit 0 to 100 km/h in 4.2 seconds with the dual-clutch transmission, or 4.4 seconds with the six-speed manual. Top speed is electronically limited at 250 km/h. However, BMW will offer what's called the M Driver's Package which bumps up the limiter to 280 km/h. Acceleration times with the M Driver's Package are the same as the ones without it, according to BMW.

There are subtle cues that differentiate the M2 CS from the rest in the 2 Series Coupe range. The kidney grill has been tweaked with an all black finish and appears to be larger for better engine cooling. Larger corner air intakes are also part of the tweaks and the front apron gets unique detailing. Minor tweaks were made to the rear bumper to accommodate the new exhaust system. Exclusive to the M2 CS is a set of 19-inch lightweight alloy wheels, similar in design to those seen in the M4 Competition Package.

As for the interior, it is largely carried over from the standard M2, save for a few minor touches. There are two M Drive buttons on the steering wheel for drivers to save their preferred settings. The instrument cluster is now fully digital, taking a page from all-new BMW offerings. Carbon fiber trimmings are present all over the cabin from the doors to the dashboard. If that's not enough, occupants are reminded that they are in a special M car when they put on their seat belts as it features the signature colors of blue, purple and red.
