1. 3.0L Twin-Turbo Inline-Six Engine

Finally, there’s the all-new, 3.0-liter inline-six engine featuring BMW’s M TwinPower Turbo technology. Boasting 425 hp and 406 lb-ft of torque, the powerplant is also 22 lbs lighter than the V8 it’s replacing. Peak horsepower is available from 5,500 – 7,300 rpm while peak torque comes in at an early 1,850 rpm and lasts until 5,500 rpm. According to BMW, the engine also achieves a reduction in fuel consumption and emissions of nearly 25 percent. The new engine has a redline of 7,600 rpm, making it unusually high-revving for a turbocharged engine helping combine the best of both worlds.
