BMW 1 Series M

According to the magazine, the smaller, lighter BMW 1 Series M Coupe is actually faster than the current model BMW M3 around the track. Sport Auto clocked a lap time of 1:14.1 minutes in the 1 M around Hockenheim, and a time of 1:14.2 in an M3 coupe fitted with the DCT transmission on the same day.
The 1 M’s 3.0-litre, 250kW turbocharged straight-six engine, it seems, is a great match for the larger 4.0-litre, 309kW V8 used in the M3. Both cars also sprint from 0-100km/h in 4.9 seconds and go on to an electronically limited top speed of 250km/h (test results do vary).
Despite recent criticisms that the new 1 M Coupe is too ‘tail happy’, Sport Auto says this is a good thing as it returns back to the BMW M car heritage. The reviewers said,
“It’s good to know that not all cars are tuned in to understeer for safety reasons.”
Some of the speculated reasons for the quicker lap time of the 1 M include it being lighter in weight (1495kg versus 1680kg [DCT]) and because it offers more torque than the bigger M3 (the 1 M offers a maximum figure of 500Nm compared with the M3′s 400Nm).

BMW Z4 GT3

Never one to rest on its laurels, BMW took the car from the winners circle in Dubai and put it right back on a test track. After a good beating throughout March, BMW made aerodynamic and electronic tweaks to get the racer into absolute state-of-the-art shape for customer entries in 2011 GT3 competition.The BMW Z4 GT3 resembles its production cousin in name and basic shape only. Most of its body panels have been significantly altered to keep the car slipping through the air and bolted to the road.
Under the hood, the production Z's six-cylinder heart has been ripped out and replaced with the same 4.4-liter V8 that sees duty in the M3. The V8 feeds power to the ground through a six-speed paddle-shifted sequential manual.
