Bro day wouldn’t be complete with an obligatory car post and today it comes from the folks at BMW who have revealed the M4 GTS powered by the world’s first water-injected engine. The GTS is not only a more powerful version of the M4, but it also comes with two tech first. The water-injected engine which increases efficiency and power significantly and OLED (organic LED) taillights. Here’s what the beast looks like.
“The 3.0 liter twin-turbocharged engine in the standard M4 makes 425 hp. For GTS duty, BMW took that engine and added water injection and some forged internals, like the crankshaft. While that doesn’t sound all that significant, it makes a world of a difference. Water Injection, a world first on the GTS, significantly lowers combustion chamber temperature by spraying an extremely fine mist into it during combustion. This decrease in temperature, by up to 80 degrees Fahrenheit, increases both power and efficiency while also reducing engine knock. With this system, power bumps up from 425 to 493 for GTS duty. That added power helps the GTS get from 0-60 mph in 3.7 seconds, down two tenths from the standard M4.” [BMW Blog]
