BMW have used this year’s Shanghai motor show to unveil their latest hardcore coupe – the M4 CS. Set for a two-year production run, it’ll be lighter, more powerful and faster than the standard M4, and will bridge the gap between that and the GTS.
The M4 CS, which stands for Club Sport, shares its name with the 2005 E46 M3 CS – an extremely good car. BMW aimed to produce a car that not only shares the name but also the character of that M3 CS and have achieved it by borrowing parts from the even more hardcore M4 GTS.
The twin-turbocharged straight-six engine has been tuned to produce an impressive 454bhp, a rise of 29bhp. With that increase in power, it’ll now do 0-62mph in 3.9 seconds and top out at an electronically limited 174mph. As well as the improved power, it’ll also do a claimed 33.6mpg and 197g/km of CO2 making it the most efficient M4 yet. Power is sent to the rear wheels via a seven-speed paddleshift gearbox – there is no manual option.
The suspension setup has been tweaked, too. The M4 CS borrows aluminium suspension components from the Competition Package, and gets standard Adaptive M Suspension which allows you to stiffen the ride to get extra grip and stability. You also get Michelin Cup tyres as standard to provide even more grip in the corners. These alterations allow it to lap the Nurburgring in 7min 38sec, a whole 22 seconds faster than the standard M4. That’s still six seconds off the Giulia Quadrifoglio but with a 503bhp Ferrari-tuned V6 engine, you’d expect the Alfa Romeo to be faster.
Another area BMW have improved on is the weight. Weighing in at 1,580kg, the M4 CS is 32kg lighter than the standard model. You can put that weight loss down to carbonfibre-reinforced plastic replacements for the bonnet, roof, front splitter, rear diffuser and even the driveshaft.
Cosmetically, the new M4 isn’t all that different but it doesn’t really need to be. Small tweaks have been made such as the slightly more pronounced front splitter and the new lip spoiler on the boot lid. The new alloys are the most noticeable change – some lovely grey DTM-style lightweight alloys designed specifically for the CS. The front wheels are 19-inches and the rears are 20-inches.
On the inside there’s subtle CS badging, new sports seats, and a lot of leather and alcantara. There are also a couple of weight-saving touches such as the lightened door cards with unique fabric door pulls rather than moulded ones.
It’s not cheap – you’ll pay £89,130 to have one on your driveway. That’s pretty much £30k more than the standard model but it is also about £30k cheaper than the GTS. Bridging the gap, like I said. As expensive as it seems, it’s not too much more than a standard M4 after going on a mad one with the options. Also, being a limited-run BMW, it’s unlikely to lose a lot of its value and it could even start rising after a while.
So what do you think of the M4 CS? Is it worth £89k or is that too much more than the standard model to justify it? Let us know in the comments section below or via our Facebook and Twitter pages.
