Rachel Singer takes Brian Johnsonfor spin in a Bentley 3 Litre Blower, and talks about this model which is so fun to drive. The front-mounted supercharger gets more air into the engine forcing the car to go faster, however with only back brakes it takes a motorcar aficionado with the right touch to tame the beast. (Brian Johnson is front-man of rock group AC/DC; a classic car racer and also hosts TV show 'Cars That Rock'.)
