The Flying Spur Speed’s powertrain produces 635 PS (626 bhp) and 900 Nm (664 lb.ft) of torque, accelerating the car to 0-60 mph in 3.7 seconds (100 km/h in 3.8 seconds), and on to a top speed of 207mph (333 km/h).

The Flying Spur uses the same 8-speed ZF dual-clutch transmission as the Continental GT for smooth and refined acceleration, quicker gearshifts and improved fuel economy. Faster gearshifts are achieved by pre-selecting the next gear, shortening the interruption of torque to the wheels and so improving performance. Maximum speed is reached in sixth gear, with the overdrive gears (seventh and eighth) used for economic grand touring.

The Flying Spur Speed has a clutched system which delivers drive to the rear axle. Depending on the road conditions and wheel slip, it will then automatically send drive to the front axle as required, as an active all-wheel drive system. Therefore turn-in response is also improved. The front end of the Flying Spur feels much lighter and changes direction almost at the speed of thought. The understeer effect experienced with fixed all-wheel drive is virtually eliminated, making the car feel more balanced overall.
