The video below shows the sound comparison between the new 2018 BWM M4 CS and the BMW M4 GTS. Both cars feature the 3.0-liter twin turbo straight-six engine, but they are different in other ways. The CS version of the model offers 460 horsepower and goes from 0 to 100 km/h in 3.9 seconds. The GTS version, on the other hand, is good for 493 horsepower and needs only 3.8 seconds to accelerate to 100 km/h from standstill.
