BMW India has confirmed that the more hardcore version of its performance sedan, the M4, will launch in India on October 4. The BMW M4 CS (which stands for Competition Sport) will be priced above the Competition (on sale in India at Rs 1.53 crore) and comes with a raft of mechanical changes that make it quicker and faster.

BMW M4 CS: powertrain

The BMW M4 CS gets an upgraded version of the standard M4’s twin-turbo 3.0-litre straight-six engine that featured in the limited-run CSL. The CS packs 20hp more than the M4 Competition’s 530hp figure, thanks to an increase in turbo boost pressure from 1.7 bar to 2.1 bar. While the CS’s torque figure is the same as the Competition’s, it sustains the 650Nm peak for an additional 220rpm at the top end of the rev range, holding it from 2,750rpm to 5,950rpm.

BMW says that the powertrain has also been revised to endure long sessions on the track: the engine’s cooling system is improved, for example, and the supply of oil to the clutch has been increased to ensure the four-wheel-drive system maintains its performance. Stiffer engine mounts, which are bespoke to the CS, are also said to improve the powertrain’s responsiveness.

The 0-100kph sprint is taken care of in 3.4 seconds, claims BMW, which is 0.1 seconds quicker than the Competition.

BMW M4 CS: chassis

The CS is 20kg lighter than the standard model, owing to a titanium exhaust silencer and various carbon fibre-reinforced plastic (CFRP) components, including the centre console, gearbox paddles and interior trimmings. The company says that the CS’s chassis has also been tuned to improve steering precision and wheel control, with stiffer springs and anti-roll bars that are also said to reduce roll through tight corners. The stability-control system has also been reprogrammed to raise the limit at which it intervenes to correct a slide.

The CS borrows its staggered lightweight wheels from the previous M3 CS, with 19-inch alloys up front and 20-inchers at the rear. These are shod in Michelin Pilot Sport Cup 2 rubber as standard, but the more track-focused Cup 2 R tyres are also available as a no-cost option.

BMW M4 CS: other changes

The M4 CS differentiates itself from the Competition with distinctive yellow-tinted daytime-running lights, which are inspired by BMW’s GT race cars, and a grille that gets a red outline.
