Today, BMW announced the first-ever BMW M3 CS, a special-edition model that delivers a fine blend of high performance and complete everyday practicality. The engineers at BMW M GmbH have succeeded in intensifying the dynamic, emotion-packed character of the BMW M3 with a carefully crafted ensemble of modifications. The extensive use of carbon fiber-reinforced plastic (CFRP), has kept the Bimmer extremely light; around 110 lb less than a standard M3. Large sections of the body are also made from CFRP, including the hood, which is around 25 percent lighter than that of the regular BMW M3. The CFRP roof alone is more than 13 pounds lighter than a conventional steel version. In the interests of everyday practicality, the M3 CS forgoes a roll cage.
The result, 0 to 60 mph sprint takes just 3.7 seconds, while the top speed of the BMW M3 CS, which comes with the M Driver’s Package as standard, is electronically limited to 174 mph.
The dynamics of the BMW M3 CS are rooted not only in unique suspension set-up (in terms of spring/damper settings), but also in a moderate increase in power for the M TwinPower Turbo technology 6-cylinder inline engine. Fitted in the M3 CS it develops 453 hp at 6250 rpm (+28 hp) and peak torque 443 lb-ft from 4000 to 5380 rpm (+37 lb-ft). The unmistakable roar of the twin turbo engine is enhanced by the M sports exhaust system that has been specially tuned for the CS and whose quartet of stainless-steel tailpipes blend perfectly into the CFRP rear diffuser.
Generous use of Alcantara and the two-tone full Merino leather in Silverstone/Black endow an enviably sporting feel. The engine is fired up with the push of a new red start/stop button. Paring down the passenger compartment to the essentials and, in so doing, achieving significant weight savings is also expressed in the presence of lightweight M sports seats. Its passengers need not go without niceties such as automatic climate control and a high-quality, specially adapted version of the Harman Kardon surround sound system.
The high power output of the 3.0-liter engine can be attributed to its free-revving design of the M TwinPower Turbo technology utilizing two mono-scroll turbochargers, which combined with High Precision Direct Injection, VALVETRONIC variable valve lift and Double-VANOS fully variable camshaft timing control ensure the 6-cylinder unit delivers its power to maximum effect. Boost pressure is built up continuously from just above idling speed, while the fully variable valve and camshaft timing help to maintain high efficiency. As a result, the inline 6-cylinder under the hood has a high rated maximum engine speed for a twin-turbocharged unit (7,600 rpm).
Orders can be placed starting May, 2018. Production of the high-performance sedan will be limited to approximately 1,200 units worldwide, with approximately 550 units coming to the U.S. Pricing will be announced closer to market launch.
