The BMW M2 has already been awarded the title of 2016 Coupe of the Year by Top Gear, but it seems the Bavarian manufacturer still thinks it can improve on the two-door pocket rocket.
This video shows the lightly disguised car, which is thought to be called the M2 CS, testing on the fearsome Nurburgring Nordschleife circuit.
As you can see, it's certainly fast, but that's no surprise when you consider that the standard M2 sprints from 0-60mph in less than 4.5 seconds and tops out at 155mph.
The CS, however, is thought to go even faster thanks to a new engine. Rumour has it the car will use the same 3.0-litre straight six as the current M3 and M4, possibly with a power output in the region of 400bhp. That would represent a power hike of around 35bhp on the standard M2 and could cut the 0-60mph time to around four seconds flat.
