The "Godfather" motor by Sonnys. 1,005.8ci behemoth with an unreal 5.220-inch bore and a 5.875-inch stroke. 2,150 hp at 8,000 rpm and 1,500 lb-ft of torque at 6,200 rpm on 112-octane fuel. That’s naturally aspirated, by the way.
The brand-new (2013) Bentley Continental GT Speed Convertible 6.0 litre W12 Engine. Wow! 616 horsepower and 590 lb. ft (800Nm) of torque. 0 – 60 miles per hour is done in a blurry 4.1 seconds, and after that the speedo climbs relentlessly, topping out at an unbelievable 202 mph (325 km/h).
