Track Tested: 2010 Range Rover Supercharged


2010 Range Rover Supercharged

Edmunds tests hundreds of vehicles a year. Cars, trucks, SUVs, we run them all, and the numbers always tell a story. With that in mind we present "Track Tested," a quick rundown of all the data we collect at the track, along with comments direct from the test-drivers. Enjoy.

There's excess, damn excess and then there's the 2010 Range Rover Supercharged. But unlike so many other 500 horsepower SUVs-- this Range Rover has 510 horsepower from a supercharged 5.0-liter V8-- this Range Rover Supercharged doesn't make any pretense towards being sporty; It's big, it's hugely powerful and it's luxurious. Why add sport?

Sure it rolls on 20's with summer-performance Michelin tires and has absurd 15-inch brakes with six-piston calipers, but sport isn't the name of the game. The ride is soft and dead-quiet despite its 4WD off-road nature. And continuing the non-sportiness begrudgingly accepts that roads have corners rather than aggressively carving through them.

The cabin is richly appointed with heated and cooled seats, four-zone climate control, a 12.3-inch TFT screen that acts as gauges,  rear seat entertainment and some of the nicest leather and carpet you'll find in any vehicle.

Acceleration Comments: Any advantage from brake-torquing evaporated by 60 mph. Don't know why. Still, this 3-ton brick is fast! Linear power all the way up to redline. Quick and smooth upshifts. Authoritive exhaust / intake honk.

Braking Comments: Good, medium-effort pedal some dive, but not shockingly so. Good fade resistance, but there were some smoldering brake pads after 5 quarter mile passes. Good performance all things considered.

Handling Comments: Slalom: Agonizingly conservative ESP with no measurable differnce between on/off (which isn't off). Skidpad: ESC is very, very conservatively tuned-- hence 0.68g. With ESC off, there was a slight release of the reigns, but not much.
