2020 Highlights - Chassis Cab & Work Truck Segment
• General Motors introduces the 6.6L L8T gas V-8, which replaces the 6.0L Vortec in commercial truck applications. The direct injection engine boasts respectable 401 horsepower and 464 lb-ft peak ratings. The L5P and L5D 6.6L Duramax diesels remain unchanged for 2020, although the Sierra/Silverado 3500HD chassis cab yields significant increases in GVW, GCW, payload, and axle weight ratings.
• Ford Motor Company introduces its 7.3L PFI V-8 gas engine and retires the long lived 6.8L Triton V-10. The big displacement engine produces up to 350 horsepower and 468 ft-lbs of torque in Ford's commercial applications, while the pickup version is rated at a peak 430 horsepower and 475 lb-ft of torque. Ford's commercial tuned 6.7L Power Stroke returns with an extra 75 lb-ft of torque, bringing peak rated torque to 825 lb-ft from last year's 750 lb-ft.
