Both Range Rovers are powered by a 5.0-liter V8. The HSE show prepares 375 hp and 375 pound-feet of torque, while the Supercharged show composes a generous 510 hp and 461 lb-ft. Both motors match with a six-speed mechanical transmission with manual change control. In Edmunds exhibition testing, a Supercharged Range Rover quickened from zero to 60 mph in 5.5 seconds a stunning time for a 3-ton SUV.
