BMW M4 GTS gets world's first water-injected engine, OLED tail lights

Some driving enthusiasts fear that as cars become increasingly more advanced that driving purity will be sacrificed. The BMW M4 GTS dashes those fears to bits.

Although the car might look like a racier version of the German brand's M4 coupe, little could be further from the truth. Because the car boasts two production car world-firsts: a water-injected engine in the front and organic light emitting diode (OLED) tail lights in the rear.

Let's start up front. BMW engineers have taken their potent 3.0-liter twin-turbocharged inline six-cylinder and, for the first time in a production car, fitted it with water injection. Though the technology has been utilized and proven on the racetrack for many years, this is the first production car to include it. It has many technical benefits. Essentially, injecting water in the cylinder along with a tiny mist of gasoline allows the engine to run at higher rpm than without the water. And, as we learned during dieselgate, higher compression engines not only run more efficiently, they also generate more power. Read more...
