The gas-powered inline-six and the new V8 will power the 2017 S-Class when it gets its facelift, while the automaker is still figuring out where to place the other motors. Mercedes confirmed to Autoblog that the new V8 will be sold in the upcoming S-Class in the US, but the automaker doesn’t plan to sell a four-cylinder S-Class here.

The inline-six engines are a return to form for Mercedes as the automaker offered the engine layout in its vehicles until the late ’90s.

These components allow the engine to make more power than the old V6 engine while also being more fuel-efficient. The M256 makes 408 horsepower and over 368 pound-feet of torque, while the older M276 V6 engine was good for 333 horsepower and 354 pound-feet of torque. A worthwhile improvement.
