The Bentley Continental GT Speed has been given an update for 2014 and it has now become the fastest production car Bentley has ever made. The 6.0-litre twin-turbo W12 engine pushes out a whopping 626 hp which makes it capable of hitting 330 km/h and being a Bentley it will probably feel like you are doing 120. They lowered the chassis, stiffened the suspension, added new exterior paint trim to front splitter, side skirts and rear diffuser and of course the classy interior has been updated to finish the package off.
