2010 Range Rover Sport Supercharged – 140 mphThe first-generation Range Rover Sport helped expand the brand's popularity. Its striking exterior proved that boxy could be sexy when it reached U.S. shores for the 2006 model year. Among the earlier engine offerings was a 390-horsepower supercharged 4.2-liter V8 that served for several years. For 2010, Range Rover revamped the engine bay with a new 5.0-liter V8 designed in partnership with Jaguar. The base version was naturally aspirated and produced 385 horsepower, while the supercharged variant cranked out 510 ponies. This enabled the Sport Supercharged to max out at 140 mph and go from 0-60 in 5.9 seconds (remember, this was 15 years ago). This performance bested the previous supercharged engine by nearly a full second, a notable improvement given the Sport Supercharged's nearly three-ton curb weight. The supercharged engine option was carried over to the second-generation Sport, which appeared for 2014. Range Rover launched the even more powerful SVR variant in 2015 — more on that in a bit.2015 Range Rover Sport SVR – 162 mphWhile the Range Rover Sport's performance tradition dates back to the first generation, the SVR moniker made its first appearance for the 2015 model year. It was powered by a supercharged 5.0-liter V8 that produces 550 horsepower and sends this steel and leather creation to from 0-60 in 4.5 seconds and to a top speed of 162 mph. Two large air intakes in the hood set the SVR apart from ordinary Range Rover Sports from this year, and inside the engine bay are two intercoolers to keep the supercharger happy. An eight-speed automatic gearbox feeds the all-wheel-drive system. To prove the Sport SVR's prowess, the automaker tested it on the famed Nürburgring Nordschleife, recording a lap time of 8 minutes and 14 seconds, a record-setting performance at the time for a production SUV. Meanwhile, this Sport SVR didn't skimp on off-road capabilities. A two-speed transfer case helps with low-speed crawl control, making it as easy to handle at 10 mph as it is at 110.
