The new Range Rover Sport SV has arrived with a little less bravado and a lot more horsepower. The 575-hp 5.0-liter V-8 from the current SVR is out, with the BMW-sourced 4.4-liter V-8 from the recently revealed Range Rover SV taking its place. Despite its smaller size, the 4.4-liter engine brings a lot to the table. First and foremost, the V-8 era lives on, even if it is a hybridized twin-turbo. The new engine boasts 626 horsepower, good to motivate the big SUV to 60 mph in a claimed 3.6 seconds on the way to a top speed of 180 mph.
