The all-new M3 Sedan feature the first V8 in a series-production BMW M3. It will also feature driver-adjustable settings for crucial dynamic controls including steering, damping and stability (and an available steering-wheel-mounted "MDrive" button to store the preferences) and a sumptuous interior that can be optimized to a driver's desires including the comprehensive entertainment/navigation system operated through BMW's latest iDrive controller.
The move to eight cylinders in the fourth generation BMW M3 provides a powerplant offering the seemingly disparate characteristics of more power, increased efficiency and reduced weight when compared with the previous six-cylinder M3 engine. Displacing 3,999 cubic centimeters (4.0 liters), the new light-alloy engine produces 414 hp at 8,300 rpm and 295 pound-feet of torque at 3,900 rpm with 85 percent of the maximum torque available consistently through 6,500 rpm. This power output represents a 15-percent increase over the six-cylinder from the last generation M3 and it comes with an eight-percent fuel-economy improvement when compared to its predecessor. Compression ratio is dialed in to 12.0:1 and redline is set at 8,400 rpm.
