 With a French Pont-a-Mousson four-speed manual gearbox the full-four-seater 6.3 litre Facel II could attain over 150 mph (247 km/h) and out-accelerate two-seat GTs such as the Aston Martin DB4, Ferrari 250 GT and 'gull-wing' Mercedes-Benz 300SL, to and all except the Ferrari to 100 mph (160 km/h).Dunlop disc brakes were fitted on all four wheels and Hydrosteer power steering, leather seats, electric windows and radio aerial all became standard during the production run, with Armstrong Selecta-Ride shock-absorbers adjustable from the dash while driving fitted to the right-hand-drive British models.The curvaceous wrap-round dash was in fact metal but meticulously painted to look like wood.
