Model Highlights

3.0-Liter, 315–hp, 6-Cylinder Engine
This unique engine combines a twin-scroll TwinPower Turbo, High Precision Direct Injection, and BMW's Valvetronic variable intake technology that helps the engine "breathe" better. The result: turbo lag is virtually eliminated, while posting one of the most fuel-efficient ratings in its class. The 640i develops maximum output of 315 hp at 4800 rpm, redlining at 7000 rpm. Peak torque of 332 lb-ft kicks in almost immediately at 1400 rpm and continues to push you back in your seat all the way to 4500 rpm.
