This is the first time BMW is offering xDrive on its compact range, with only the 120d and M135i models getting the option initially.
The all-wheel drive system varies the drive torque between the front and rear axles, improving handling and safety. It relies on an electronically controlled multidisc clutch and in normal operating conditions sends 60 percent of torque to the rear wheels to ensure the all-wheel drive 1-Series models maintain their rear-driving characteristics.
Linked to the standard electronic stability control, xDrive all-wheel drive will adapt this distribution to the given situation almost instantaneously. For example, by directing additional drive power to the rear wheels early on, it is possible to counter any tendency towards understeering. Oversteering, meanwhile, can also be eliminated by directing most of the engine power to the front wheels.
With the added traction of xDrive all-wheel drive, BMW’s M135i M Performance, rated at 320 horsepower, will sprint from 0-60 mph in just 4.7 seconds and go on to easily reach its electronically limited top speed of 155 mph.
Also on BMW’s stands at the 2012 Paris Auto Show will be several new vehicles as well as some we’ve already seen.
