7. PORSCHE 911 GT2 RS: 211 MPH
There are very few places in the world where someone can legally open the throttle and push a vehicle’s speed to an absolute limit, but the runway at the Johnny Bohmer Proving Grounds in Merritt Island, Florida, is one of them. In this video, a Porsche 911 GT2 RS proves whether the factory-rated top speed of 211 miles per hour (340 kilometers per hour) is really accurate.
And shine the Porsche does. It’s listed as having no modifications, but even in stock trim, the GT 2 RS delivers 690 horsepower (515 kilowatts) to the ground thanks to its twin-turbocharged 3.8-liter flat-six. It seems to launch fairly well, though, with a manufacturer-published 0-60 time of 2.7 seconds, this specific car seems a bit slow off the line. From there the speedometer relentlessly climbs to triple digits, hitting 100 mph in just 7 seconds, 150 mph in 15 seconds, and 200 mph in 29 seconds. The speed only starts to wane shortly before the 200-mph mark, but it continues a slow-yet-steady ascent to 215 mph and barely manages to click 219 mph before crossing the shutdown line.
6. ASTON MARTIN DBS SUPER LEGGERA: 211 MPH
The new Aston Martin DBS Superleggera Volante has officially broken cover, with a top speed of 211mph making it the fastest convertible Aston has ever produced. Prices start at £247,500 – a hefty premium over the £175,000 asked for the Bentley Continental GT Convertible. Despite the identical top speed, DBS Superleggera Volante weighs a not inconsiderable 170 kg more than the coupe, at 1863 kg, which marginally affects acceleration. Aston claims a 0-62 mph time two-tenths slower (3.6 sec) and a 0-100 mph time three-tenths slower (6.7 sec) than the coupes.
The twin-turbocharged 5.2 liter V12 produces an identical 715 bhp and 664 lb-ft of torque to the coupe, too. Estimated fuel economy is reduced from the 22.9mpg of the coupé to 20.1mpg under the new WLTP testing regime.
