BMW X3 M – Powertrain
EngineThe latest inline six-cylinder engine from BMW M maintains the 3.0-litre displacement, upgraded with many new components. Power outputs of the BMW S58 engine in the F97 BMW X3 M Competition coupe are 510 PS at 6,250 rpm and 600 Nm from 2,600 to 5,950 rpm.
Drivers will be happy to know they can spin the engine to 7,200 rpm, similar to the latest BMW M3 and M4 models. The high-revving engine that has a linear power delivery also sounds ferocious thanks to a standard fitted M Sport exhaust system, which can be quiet down for a civilized drive around the neighbourhood.
BMW says the cooling system and oil supply have been designed for track use. Apart from a powerful electric fan, the intercooler also has its own cooling supply, and an electric water pump keeps coolant flowing to the two turbochargers even when the engine has been turned off.
TransmissionIn the F97 BMW X3 Competition, the transmission is a specially-developed eight-speed M Steptronic automatic transmission with shift paddles and Launch Control function. The Drivelogic switch allows the transmission to shift in three driver-selectable programs- Mode 1 for comfort, Mode 2 for sports or Mode 3 for track. The durability of the transmission fluid is ensured by a dedicated cooling radiator mounted at the front.
Chassis The bodyshell of the BMW X3 Series has been modified to suit the usage of being a BMW M car. High amounts of reinforcement members are strategically placed for maximum stiffness and rigidity. A panoramic glass roof is fitted as the BMW X3 M Competition is after all a family-oriented SAV.
The front suspension features a double-joint strut axle setup, while the rear axle uses a five-link layout. The majority of the suspension components are in aluminium material, a trademark of modern BMW M cars. There is also M Servotronic steering rack with a variable ratio.
Electronically-controlled Adaptive M suspension is standard in the F97 BMW X3 M Competition. M Compound and cross-drilled brakes discs meanwhile measure 395 mm in front and are grabbed by four-piston fixed-caliper brakes, while the rear axle features 370 mm cross-drilled discs and actuated by single-piston calipers.
As always, staggered wheels and tyres are standard fitment in the new BMW X3 M Competition. The front wheels are wrapped with 255/40R21 tyres while the rear is marginally wider with 265/40R21 tyres. A tyre repair kit is included as these are not run-flat tyres (RFT).
Excellent traction and agility are intensified by the M Sport differential, where an electronic system variably controls the independent torque levels of the left and right rear wheels. Delivering more torque to the outside wheel with more grip enhances traction out of the corner.
DrivetrainThe F97 BMW X3 M Competition is only available in the performance-oriented M xDrive all-wheel drive layout. Predominantly rear-wheel drive, the clever M xDrive will only shuffle power to the front axle when the stability control tells it to. There is also a 4WD Sport mode for an even higher degree of rear bias in 4WD mode, making it more fun to drive on windy roads.
