Similarly to the four-cylinder cars, the only difference between the RWD M440i and the M440i xDrive is the AWD system, which adds 117 lbs to its weight, mostly over the front axle. Despite the weight increase, superior off-the-line traction means the xDrive reaches 60 mph 0.3 seconds sooner with a time of 4.3 seconds. Fuel consumption is also slightly worse than the RWD car's 24/32/27 mpg.
