BMW M GmbH has presented the latest generation of the M3 Sedan and M4 Coupe, alongside their Competition variants.

The new BMW M3 Sedan and BMW M4 Coupe, as well as their Competition models now feature an M-specific version of the large, vertical BMW kidney grille with horizontal bars. Powerfully sculpted wheel arches and the prominently extended side sills feature at the flanks of the cars.

The sedan and coupe also have a roof made from carbon fibre reinforced plastic with aerodynamically optimised fins, a rear spoiler and the two pairs of exhaust tailpipes.

Full-LED head lights are fitted as standard, while Adaptive LED Head lights with BMW's Laserlight can be specified as an option.

The selection of exterior paint finishes includes the new and exclusive shades of Sao Paulo Yellow non-metallic, Toronto Red metallic and Isle of Man Green metallic. An optional M Carbon exterior package and model-specific BMW M Performance Parts can be ordered from launch.

The new BMW M3 Sedan and new BMW M4 Coupe are fitted with a 3.0-litre in-line six-cylinder engine with M TwinPower Turbo technology. 473bhp from the engine is channelled to the rear wheels via a six-speed manual gearbox.

In the new BMW M3 Competition Sedan and new BMW M4 Competition Coupe, the 503bhp version of the high-revving unit teams up with an eight-speed M Steptronic transmission with Drivelogic. The two Competition models will also be available with the M xDrive all-wheel drive system.

The engines powering the new high-performance cars blend the high-revving tendencies for which M models are renowned with the latest version of M TwinPower Turbo technology.

Two turbochargers with indirect charge air cooling, a flow-optimised air intake system and a petrol direct injection system working with a maximum pressure of 350 bar help to generate the engine's instantaneous power delivery and appetite for revs, which it sustains without interruption into the higher reaches of the engine speed range.

The engine powering the new BMW M3 Sedan and new BMW M4 Coupe serves up peak torque of 550Nm all the way from 2,650rpm to 6,130rpm. The unit fitted in the Competition models meanwhile maintains peak torque across a wide rev band, with 650Nm on tap between 2,750rpm and 5,500rpm.

These outputs mean the new BMW M3 Sedan and BMW M4 Coupe requires just 4.2 seconds to power from zero to 100 km/h. The Competition models each accelerate from zero to 100 km/h in 3.9 seconds.

Adaptive M suspension with electronically controlled shock absorbers and M-specific kinematics and elastokinematics for the front and rear axles are standard features of the new BMW M3 Sedan and new BMW M4 Coupe.

They also have M Servotronic steering with a variable ratio and an M-specific version of the integrated braking system, which presents the driver with two different brake response and pedal feel settings.

The introduction of an integrated wheel slip limitation function allows the Dynamic Stability Control system to work with increased precision, and now comes with an M Dynamic Mode, opening the door to a particularly sporty driving experience, complete with a controlled drifting ability.

Standard specification also features forged M light-alloy wheels - in 18-inch format at the front axle and 19-inch at the rear. Tyres are 275/40 ZR18 items at the front and 285/35 ZR19 at the rear

Inside the of the new BMW M3 Sedan and new BMW M4 Coupe are newly developed, electrically adjustable M sport seats and fine-grain Merino leather trim, with seat ventilation also available for the first time.

A standout highlight of the options list are the new M Carbon bucket seats with a structure-based design, which combine racing functionality with a lightweight construction, comfort over long distances and sumptuous workmanship.

These innovative seats have integrated head restraints which can be dismantled for track driving, and an illuminated model badge and electric adjustment. Their racing-car-inspired structure also enables the use of multi-point seat belts.
