The latest BMW M3 and M4 cars were only just launched this month here in the UK and already BMW has updated the range with a new option for wheel drive, like the latest BMW M5. However the M3 and M4 can be ordered in a rear wheel drive only or four wheel drive configurations.
The new M3 and M4 Competition xDrive and will go into production this July, both cars will have the same 3.0-litre straight six, with 503bhp and 479lb ft torque. However, thanks to the four wheel drive system, the 0-60mph time has been reduced from 3.9 seconds to 3.5 seconds.
Both cars have an eight speed automatic gearbox too, with the car being set up to be rear wheel drive biased. Sport mode uses even more of the rear axle and then finally the 2WD mode actually physically disconnects the two halfs of the car.
M3 Competition xDrive starts from £77,015 and M4 Competition xDrive from £78,315.
