First Drive: BMW hits the lightweight nail on the head with the M3 CS
The M3 CS is a limited-edition version of BMW’s popular sporting saloon. James Baggott got behind the wheel to see what it’s like

What is it?
Meet BMW’s latest lightweight hero – the M3 CS. After a strict greens-only diet from a motorsport-inspired engineering division, the M3 has managed to shed 30kg of flab and gain some intoxicating driving characteristics in the process.

What’s new?
In an attempt to shave those all-important kilos, BMW fitted new forged alloy wheels and replaced heavy panels, such as the roof and bonnet, with carbon-fibre-reinforced plastic. The front seats have been thrown out in favour of new weight-saving replacements, while even the centre console has been stripped back and lightened.

But don’t let that put you off – this is still one very special machine indeed.
What’s under the bonnet?
BMW has worked its magic under the bonnet to extract more horses from the already-impressive 3.0-litre twin turbo unit. Power is up 10bhp to 460bhp while torque increases nine per cent over the 550Nm in an M3 Competition Package to 600Nm.

What’s it like to drive?
On road or track, the CS is astonishing. Revving to a heady 7,600rpm, the engine is awash with power, accompanied by a noise that sends shivers down your spine like a first love.

The way the CS sheds speed, thanks to huge carbon ceramic brakes, is a close match for a direct impact with a tree, while the seven-speed DCT automatic gearbox is a delight, rocketing through gears faster than an Aldi assistant firing a week’s shopping down the checkout.
How does it look?
A pretty carbon-fibre spoiler, wailing quad exhaust pipes, speed-bump-kissing front splitter and distinctive matt purple paintwork (one of five unique colours) help the CS stand out from the fast-lane-inhabiting 3 Series crowd. Low-slung and aggressive, it’s lost none of the M3’s imposing road presence.
What’s it like inside?
Inside, an optional BMW M Performance Alcantara steering wheel with 12 o’clock marker is a must-buy. I

What’s the spec like?
Adaptive LED headlights, electrically folding mirrors, navigation and parking assistance all come as standard, with the rear-view camera relegated to the options list. Why? It saves weight…
