Wild BMW M4 GTS concept revealed

BMW has revealed the most extreme version of the M4 sports coupe yet. The GTS knocks up the performance of the M4 another notch by being lighter, faster and more focused than ever.

You can’t buy one just yet — this car is officially only a concept — but BMW has already confirmed that a production version will follow in the near future, and we expect it’ll look just like this concept.

It looks meaner than the normal one…

The GTS sets itself apart from the current M4 with some rather bold styling add-ons. A front splitter with a bright-orange accent juts out from below a bumper which features larger air intakes, and a huge rear spoiler sits on top of the boot lid. You can see the differences between the GTS and standard M4 below.

These changes aren’t just for show though — the splitter and the rear wing are made from carbon fibre and can both be manually adjusted to alter the aerodynamic balance of the car, while the new front bumper improves both cooling and aerodynamic efficiency. The carbon-fibre-reinforced plastic bonnet is lighter than the standard metal item, lowering the GTS’s centre of gravity to help it feel more agile through the corners.

Further improving that cornering ability should be the new alloy wheels and tyres. Measuring 19 inches at the front, 20 inches at the rear and finished with eye-catching orange accents, they are wrapped in super-grippy Michelin Pilot Sport Cup 2 tyres.

Is it any faster than a standard M4?

While BMW has not quoted official power and torque figures, the engine in the GTS offers more grunt than the standard car’s 425hp output. The 3.0-litre twin turbocharged straight six has been treated to a water injection system to help cool the engine, allowing the turbochargers to run at a higher boost – we expect to see about 500hp. Combined with the reduced weight, this should see the GTS improve on the M4’s already impressive 4.1-second 0-62mph time.

Anything else I need to know?

Also showcased for the first time on the GTS are new OLED (organic light-emitting diode) taillights. The new tech allows a much flatter light surface with a broader illumination, giving designers scope to produce many more fancy lighting designs than are currently possible with LED units or plain-old regular bulbs.
