BMW M Head of Development Talks BMW M4 CS

If you can stand vertical video (or are reading this on a phone) having the M head of Development discuss in detail the BMW M4 CS is a treat.

The M4 CS is a continuation of the M4s development and in many ways represents both what BMW M should have come to market with and a peak into the future of the M4.

    More information is trickling out on the sixth generation M3 and M4. Next year, BMW will introduce the all-new 3-series Sedan, code name G20, followed in 2019 by the Touring (G21) and in 2020 by the 4-series Coupe (G22) and Convertible (G23).

    The next generation M3 (G80) due in 2021, and M4 (G82) will remain faithful to the twin-turbo 3.0-litre found in the current car, but its power output is said to equal that of the limited-edition M4 GTS, which musters 493hp and 442ft lbs torque.

    In addition to M-specific tweaks, the future M3 and M4 will benefit from changes made to the volume models. The biggest changes will be made to the M4 Convertible (G83) which switches from the bulky retractable hardtop to a power-operated fabric top.

    The new M3/M4 are also said to be adding optional on-demand all-wheel drive, its output boosted by a 48-volt mild hybrid system, electrically spooled turbos and the GTS’s water-injection system.

    In line with the new M5, the smaller M3 model will abandon the current seven-speed dual-clutch transmission in favor of an eight-speed auto offering a choice of shift speed and shift patterns. If a manual survives it will be available only with rear drive.

    More information has come to light on project code F87 – the M2 CS – scheduled for launch in the second quarter of 2018. The M2 CS – a more extrovert beefed-up M2 -introduces a number changes over the base model.

    The key element is the stronger 3-0 litre straight-six, developing 402hp and 370ft lbs torque, and is expected to shave three tenths of a second off the acceleration time, for 0-60mph in 4.2secs, making it close to the M4 with the Competition Package.

    A key mission for the CS pack was to take weight out of the car, to include an aluminium roof, composite panels, thinner glass, lighter suspension components and stripped-back sports seats, saving around 55lbs including the bigger brakes, wheels and tires.

    There could be even more to come. Pencilled in for 2019, a range-topping M2 still awaits final clearance. Previously known as the CSL, the limited-edition will likely wear the GTS tag M Division now reserves for its rawest cars.

    Deviations from the CS are said to include a dual water-injection system increasing power to 444hp and 405ft lbs torque, a targeted additional 50lbs in weight saving, a faster-shifting transmission and the high-tech diff borrowed from the M5.
