If you missed out on the BMW M4 GTS, here’s a good news: the BMW M4 CS have just been unveiled at the Auto Shanghai 2017. Although don’t expect the GTS’s exclusivity and performance figures on the M4 CS, because it’s positioned below the water-injected special.
What’s the difference, you ask? The 3.0-litre twin-turbo straight-six in the M4 GTS develops 500 hp and 600 Nm courtesy of the water injection system, but the M4 CS foregoes that fancy tech. Therefore the same engine in the M4 CS produces ‘only’ 460 hp but still delivers 600 Nm of torque.
Bear in mind, that’s still 29 hp and 50 Nm more than the standard M4, and 10 hp more than the M4 Competition Pack. And no, there will be no manual transmission option, because the M4 CS only comes with a seven-speed M DCT. Century sprint is done in 3.9 seconds, and the M4 CS has a limited top speed of 280 km/h.
Like its cooler sibling, the M4 CS is very concerned about its weight. There’s the same carbon fibre bonnet and rear diffuser as the M4 GTS, but the carbon fibre front lip is not adjustable and on the boot lid sits a simpler carbon fibre gurney flap instead of the taller and adjustable wing spoiler.
The lightweight wheels are new in design, but they follow the GTS’s setup. The fronts are 9 J x 19 and the rears are an inch bigger at 10 J x 20. They are wrapped in bespoke Michelin Pilot Sport Cup 2 rubbers measuring 265/35 R19 at the front and 285/30 R20 at the rear. As standard, the M4 CS is fitted with BMW M compound brakes, but BMW M carbon ceramic brakes are available as an option. You’ll also notice that the M4 CS also gets the flashy OLED rear lights from the GTS at no extra cost.
Inside, the M4 CS retains the lightweight door cards from the GTS, but everywhere else it’s more lavish and more habitable for the daily grind compared to the GTS because the M4 CS sits four like a normal M4, and there’s none of that orange scaffolding behind the front seats like in the M4 GTS.
This San Marino Blue Metallic is exclusively available on the M4 CS along with Lime Rock Grey Metallic, but there will be limited units of the M4 CS painted in Frozen Dark Blue II. While the production of the M4 GTS was limited to 700 units, BMW will churn out the M4 CS for two years from July, which roughly translates around 2,000 to 3,000 units. In Europe, the BMW M4 CS is priced at €116,900.
