Our spies have sent us a big batch of images with a near-production prototype of the BMW M4 GTS.

Our spies have sent us a big batch of images with a near-production prototype of the BMW M4 GTS.

It seems the series production car will stay very close to the concept as this prototype appears to be virtually the same, although the camouflage on the taillights indicates there will be some updates. It will be interesting to see whether the concept's OLED taillights will be carried over onto the production car or BMW will decide to stick with LEDs.

As for the rest of the car, the body has remained basically unchanged and includes that fixed rear wing along with the Acid Orange accents on the carbon fiber front splitter as well as on those bespoke 19-inch front & 20-inch rear lightweight forged alloy wheels. To keep weight down, the hood is made from carbon fiber reinforced plastic and it is believed the production car will forgo the rear seats as a measure to achieve a 100 kg (220 lbs) weight loss.

There will also be some major tweaks for the six-cylinder TwinPower Turbo engine as it's set to adopt a water injection system that will increase output from the current 431 PS (317 kW) to as much as 500 PS (368 kW), although we are not entirely sure the power boost will be so big.

BMW will likely unveil the M4 GTS in production guise before the end of this year and it will obviously be a lot more expensive than the standard M4 which in Germany kicks off at €72,500.
