Sources suggest that the prototype has front wheels equipped with what seems to be a hub that’s similar to the kinetic energy recovery system which is currently in use on Formula One cars. The tech results in enhanced performance by using the kinetic energy from the brakes to spin a flywheel that ultimately generates more power.
The C-Class coupe test mule that was spotted also had an analog instrument cluster. Considering this is an early version of the test car, it is possible that the model could debut with a digital screen like on the E-Class. Mercedes may also replace the current 2.1-litre diesel engine with the E-Class' new 2.0-litre four-cylinder diesel motor. Nevertheless, the petrol motors along with the seven and nine speed automatic transmissions are expected to be carried over.
Though there’s been no official statement from Mercedes-Benz regarding the facelifted C-Class coupe, expect it to be in showrooms in 2018.
