Presiding at the top of the BMW M line is the M6 Gran Coupe ($119,800 starting MSRP); it’s powered by a 560-hp 4.4L M TwinPower Turbo V8 rated at 500 lb-ft of torque. Equipped with a 7-speed M Double Clutch, it reaches 60 mph from a standstill in 4.1 seconds. The AMG® E 63 S Sedan ($104,400 starting MSRP) has no problem beating those numbers; it gets a 603-hp AMG® 4.0L V8 biturbo rated at 627 lb-ft of torque. It’s faster, too. With its AMG® SPEEDSHIFT® MCT 9-speed, it glides to 60 mph in 3.3 seconds.
But here’s what’s exciting: that’s not even the full scope of the AMG® line’s power. Select models, such as the AMG® S 65, get an even stronger AMG® 6.0L biturbo V12 engine that summons up to 621 hp and 738 lb-ft of torque. You won’t find that under the hood of any BMW M!
