The 2015 Ford F-550 Super Duty is a heavy-duty truck built to handle demanding tasks with ease. At the heart of this vehicle is a choice of two engines: a 6.7L Power Stroke V8 Turbo Diesel with 440 hp or a 6.8L Triton V10 Gas with 362 hp. Both engines are mated to Ford TorqShift 6-speed SelectShift Automatic transmission with powerful capabilities. Four wheel drive is standard on all models. The Ford F-550 comes in three trim levels, the basic XL, the intermediate XLT and the luxury Lariat. Notable features include Ford SYNC with voice-activated controls and hands-free calling, a 4.2-inch LCD productivity screen, and an available navigation system. Advanced safety features include Trailer Sway Control and Roll Stability Control. The Ford F-550 Super Duty remained largely unchanged for the 2015 model year.
