In terms of looks, the 2010 Range Rover Sport got a mild restyle in the front fascia and rear side. Up-front, lies a new new 'three-stripe' LED indicator headlights as the Range Rover, two-bar mesh grille, as well as a restyled bulging front-bumper. The side vents are cued from the Discovery, but those new rims are Range Rover Sport special. At the back, more bulging goes to the rear-bumper, and darken treatment for the taillights.
Inside, the Range Rover Sport gets it's own new interior with cues from the Range Rover and Discovery. The squared air-vents for the air-conditioning is distinctive for the Range Rover Sport, and a new layout as well. In fact, Land Rover claim that this fascia now has 50% fewer switches and buttons than before, thus offering a cleaner look.
Engine line-up is wide. It offers both engines in the Range Rover and the Discovery. So for diesel, there's the new 3.0L twin-turbocharged V6 with 245 hp and 442 lb-ft of torque, and the top-end 5.0L supercharged V8 with 510 hp and 460 lb-ft of torque, which both are originated from Jaguar. Engines are mated to a revised ZF HP28 6-speed automatic transmission. 0-60 times variate in a big margin, 9.0 seconds for the 3.0L diesel unit, and 4.9 seconds for the supercharged V8.
Like the new facelifted Range Rover and Discovery, the Range Rover Sport got some tweaks and fiddles in the cache's computer to improve handling. The facelifted model sees the introduction of new systems such as Adaptive Dynamics that works in conjunction with the existing Dynamic Response, and the addition of the more road-focused Dynamic Program to the Terrain Response system.
Considering all factors, this Range Rover Sport is a direct rival to BMW's new X5 M and X6 M.
