BMW M2 CS spied looking like a fun track toy at the Nürburgring (Chris Bruce)

The engine makes a tremendous sound when the driver gets on the throttle.

The BMW M2 CS is on the way, and this spy video catches some test mules at the Nürburgring. There's also an extended look at the rear of the coupe while it's driving on the highway near the track. One of the M2 CS test mules only appears to have camouflage over the front splitter, and the other has a concealing wrap over the entire body. Both of them sound great.

More spy material:

Compared to the already aggressive M2, the CS variant is subtly meaner. There are tweaks to the inlets in the fascia and a power bulge in the bonnet. An earlier leak suggests the roof, mirror caps, splitter, and bonnet are carbon fibre. The test mules in this video wear the black-finished wheels, but a report indicates that matte gold versions would be available, too. Customers could also select between Michelin Pilot Sport Cup tyres or non-Cup rubber for folks looking for a regular daily driver. If someone intends to hit the track often, then there are available carbon-ceramic brakes

On the inside, there are seats with thick side bolsters for gripping the front occupants during hard driving. The thick steering wheel has Alcantara upholstery, and the material covers some other surfaces, too.

The CS reportedly uses BMW's S55 twin-turbo 3.0-litre inline-six engine making 444 bhp and 406 lb-ft. Customers allegedly can choose between a six-speed manual or seven-speed dual-clutch gearbox. The latest info suggests the M2 CS debuts in November at the Los Angeles Auto Show. Expect deliveries to start in 2020.
