BMW M3 & M4 debut on official terms

The long wait is over: BMW has removed the wraps from its new M3 and M4 models. Both debuted in their topmost Competition spec armed with the 3.0-liter turbo-six engine of the X3 M and X4 M, but with higher torque.

Specifically, the engine has been tuned to deliver 650 Nm (480 lb-ft) of torque between 2,750 and 5,500 RPM. The old version could deliver no more than 600 Nm (443 lb-ft) in the same RPM range. The rev count stays capped at 7,200 RPM.

Both cars use the M Steptronic eight-speed A/T of the M5 and benefit from the M xDrive AWD system that can send the entire torque to the rear wheels when necessary. Aside from the regular 4WD, available modes include 4WD Sport (more rear-axle torque) and 2WD (no stability control, RWD only). Drifters will know to appreciate the inclusion of the M Dynamic Mode in the standard feature list.

No details have been revealed about the non-Competition M lineup. All we know is that it gets 480 hp (358 kW), six-speed manual and RWD. Sales of the 510hp/AT/RWD sports cars will begin in March, followed by their 4WD counterparts in summer. Getting from zero to 100 km/h (62 mph) will be a matter of 3.9 seconds, and while the speed limited normally resides at 250 km/h (155 mph), you may opt for the M Driver’s Package to have it raised to 290 km/h (180 mph).

Compared to their non-M counterparts, the new M3 and M4 feature struts and braces meant to improve its structural rigidity, as well as different chassis components, M Servotronic steering with variable gear ratios, and M Suspension with electronically controlled shocks.

Paying extra will bet you the M Drive Professional Package with traction control and telemetry features, as well as the M Race Track Package with carbon-ceramic brakes, lightweight wheels, M Carbon seats, Laserlight headlights, and a stainless-steel roof with a hatch in it coming to replace the CFRP one.

The color palette now includes such new shades as Isle of Man Green, Toronto Red and Sao Paulo Yellow.
