BMW hasn’t been shy about adding all-wheel drive to the M3 and M4, and it’s finally happened as the company has unveiled Competition variants with M xDrive. While the models are equipped with a familiar twin-turbo 3.0-liter six-cylinder engine that produces 503 hp and 650 Nm of torque, it’s backed up by an eight-speed automatic transmission and an M-specific all-wheel drive system.
The system features an “electronically
controlled multi-plate clutch in the transfer case for smoothly adjustable,
fully variable distribution of drive torque between the front and rear wheels.”
Other highlights include an Active M differential, specially engineered drive-
and output shafts, as well as a transfer case which features a bespoke control
unit that allows for integrated wheel slip limitation. The all-wheel drive
system features three different modes and the default setting is rear-biased.
4WD Sport sends even more torque rearward, while 2WD mode will appease purists
who only need all-wheel drive on occasion.
Of course, BMW didn’t just throw in an
all-wheel drive system and call it a day. Instead, they equipped the cars with
a redesigned double-joint spring strut front axle and a retuned steering ratio.
The company said these changes “ensure that both the existing pure
rear-wheel-drive variants and their new M xDrive siblings stand out with their
engineered-without-compromise, signature M steering characteristics.” Other
highlights include an upgraded engine oil supply system and an M-specific
traction control system which works with the Dynamic Stability Control system
to “produce a supremely dynamic driving experience blending the customary M feeling
with noticeably enhanced traction and directional stability.” The models also
feature 19- and 20-inch forged wheels with a Jet Black finish.
Thanks to the trick all-wheel drive
system, both models can accelerate from 0-100 km/h in 3.5 seconds.
This makes them 0.4 seconds quicker than their rear-wheel drive counterparts.
If drivers keep their foot on the gas, they can eventually hit a top speed of
up to 290 km/h. The M3 and M4 Competition will be launched in Germany
this July, while Americans will have to wait until August. When they cross the
Atlantic, pricing will start at US$ 76,900 for the sedan and US$ 78,800 for the coupe
– excluding a US$ 995 destination charge.
