Bentley released its 2013 Continental GT Speed at the Goodwood Festival of Speed 2012 and has billed it as their fastest production model ever. The new performance flagship boasts 616 hp from its 6.0-liter 48-valve, four-cam, twin turbocharged W12 engine, sporting a newly revised ZF eight-speed automatic transmission. It can go from rest to 620mph in 4.0 seconds with a top speed of 205 mph. It also features a lowered, uprated suspension with unique 21-inch Speed wheels, speed grille and exhaust pipes plus a Mulliner Driving Specification interior. The new model will be available for deliveries come October.
