Ford F650

Bringing new meaning to the phrase 'monster truck', Ford's mighty F650 measures 6.5 metres long and heaves 5.2 tonnes of bulk down the interstate highway. Powered by a 6.7-litre Cummins six-cylinder diesel engine, it has 'only' 320bhp but a mighty 738lb ft of torque. Americans have taken the F650 to their hearts as a passenger vehicle, with lots of aftermarket companies offering conversions to boost its luxury and usability.
