Serious work trucks are judged on 2 main criteria; towing and payload. So Ford is ratcheting up both in their all-new 2020 Super Duty. Shipping to dealers this fall, the Super Duty lineup which includes the F-250, F-350 and F-450 is powered by a 6.2-liter gas V8 as standard or customers can upgrade to the next generation 6.7-liter Power Stroke diesel V8 making more horsepower and torque or opt for a new entry; a 7.3-liter gas V8. Though numbers have not been released, Ford says they expect the 7.3 to be the most powerful gas V8 in its class. All 3 engines will use a new Ford-developed 10-speed automatic transmission designed for the harshest towing conditions.
