The Range Rover is available with a trio of powertrains, starting with a turbocharged inline-six with a 48-volt hybrid system dubbed P400 that develops 395 horsepower. During our initial test drive, it proved to be silky-smooth and provided adequate pep to tug the large Range Rover around. A 523-hp twin-turbo 4.4-liter V-8 engine—Land Rover calls it P530—is even perkier and cranks up the Range Rover's towing capacity to 8200 pounds.
