The next best thing to the already sold-out GTS; the M4 CS
With the BMW M4 GTS already been long sold out, customers wanting a more track-oriented M4 only had the option of the Competition Package. Now, BMW has unveiled a beefier version of the the sports coupe, the M4 CS. The new “CS” suffix signifies a model more powerful than the previously mentioned Competition Package.
Much like the M4 GTS that came before it, the M4 CS will also be available with a seven-speed, dual-clutch transmission only, and will not be offered with a manual transmission. The reason being that BMW says the DCT changes gears in a fraction of a second and has a longer seventh gear to lower fuel consumption on the road.
One of the most significant updates found on the M4 CS is the more powerful 3.0-liter straight-six bi-turbo engine, which now produces 460 PS and 600 Nm of torque. With the new power ratings, there is now an extra 10 PS and 50 Nm of torque increase from the Competition Package.
Apart from the more powerful engine, the M4 CS has also undergone a diet, shaving off 32 kilograms off the standard DCT M4. This was done by making extensive use of carbon fiber reinforced plastic (CFRP) in certain areas such as the roof. The diet, combined with the more powerful engine, allows the M4 CS to go from 0 - 100 km/h in 3.9 seconds and have an electronically limited top speed of 280 km/h.
Inside, the cabin has also been treated to the lightweight diet by using compacted natural fibers for door panels and side trim. Despite being more track-oriented, the car retains standards amenities a driver would find inside the standard M4 along with a bespoke variant of the audio system.
On the oustide, the body has been slightly modified by optimizing airflow to the car thanks to a new carbon fiber splitter, rear diffuser and a lip spoiler, found only on the CS model. Also new are the lightweight alloy wheels that measure 19-inches at front and 20-inches at the rear. Grippy Michelin Pilot Sport Cup 2 tires come as standard on the M4 CS. BMW also tweaked the suspension by revising the springs and damper settings.
All the upgrades allowed the M4 CS to achieve a time of 7 minutes and 38 seconds around the Nurbugring. Even though it's 10 seconds slower than the M4 GTS, it is still 14 seconds faster than a regular, DCT equipped, M4. Sales of the M4 CS will begin in the middle of 2018.
