Every generation of the BMW M3 has had a derivative that best encapsulates what the model is about: high performance. Not that the M3 or M4 are lacking much in standard guise. But there are those enthusiasts who demand just a bit more focus. They want M Power in all its unadulterated glory – forget the pragmatic stuff.
But according to BMW, the new M4 GTS will offer “unrestricted everyday usability” in addition to serving as an out-and-out track day machine. The concept version of the model was unveiled recently and from the photography, we are sure you are going to agree that it looks rather promising.
The GTS concept also previews technologies that will filter down to the rest of the BMW line-up in the not-too-distant future. This includes a water injection system, promising more power and better economy. Here’s how it works. A fine spray of water is injected into the plenums of the intake manifold. The water vaporises and the intake air is cooler. So compression temperature is less and that, according to BMW, allows the turbocharged engine to use higher boost pressure and earlier injection timing. They also say this contributes to the durability of the engine, since there is less thermal stress on components.
Carbon-fibre-reinforced plastic (CFRP) has been used extensively to keep weight down. The front splitter is adjustable and there is a fixed rear wing too, aiding aerodynamics. Interestingly, the alloys worn by the car have been named the “666 M” option by BMW. And they are licked with Acid Orange accents. Not much has been said about the numbers. But since its forebears have always been about purity, one cannot expect a massive gain in outputs – rather, a holistic sharpening of the existing package.
