BMW M Studio in Garching is the one place where any BMW fan feels like a kid in Candyland. The private studio lives inside the M factory and hosts some of the most exclusive M cars ever made. Just recently, the studio hosted an online reveal of the new BMW M2.
We were given the unique opportunity to visit the M Studio several times in the past, including during our BMW 1M delivery in 2011 and it has been a fascinating experience.
Now, another special M car joins in Garching – the M4 GTS – and for the first time, we get the chance to hear the engine and exhaust sound.
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.
There is also a titanium muffler on the exhaust system, ensuring further weight saving.
