2020 Chevrolet Silverado 3500 HD – What We Know So Far

Just like the 2019 Silverado, the 2020 Chevrolet Silverado 3500 HD is also getting a major update. With new styling, a stiffened up frame, and a host of new features, the 2020 Chevy Silverado HD is poised to sit on top of the hill once again.

Some things change, some things stay the same. That seems to be the motto of the all-new 2020 Silverado HD because the 6.6L Duramax turbo-diesel remains unchanged but an all-new 6.6L gasoline engine accompanies it.

6.6L V8 Duramax Turbo-Diesel

The 6.6L V8 diesel engine remains unchanged from the previous generation Silverado HD. It produces 445 hp and 910 lb-ft of torque at 1,600 rpms. The big change though is that it’s now paired with a new 10-speed Allison automatic transmission. It features a revised Tow/haul mode for better control and improved cooling when towing or hauling heavy loads. It also features Auto Grade Braking that automatically downshifts when needed to enable engine braking, helping to slow the 3500HD on downhill grade and reduce brake wear.

6.6L V8 Gasoline

The new 6.6L V8 gas engine produces 401 hp and 464 lb-ft of torque at 4,000 rpms. It features Direct Injection and Variable Valve Timing and is paired with a 6-speed automatic transmission. The 6-speed automatic also features Auto Grade Braking just like the 10-speed Allison transmission.


With a tougher frame, the 3500HD Silverado can tow an incredible 51% more than the outgoing version when equipped with the dual rear wheels. The max 5th wheel trailering figure is now at 35,500 lbs with the DRW and 21,500 lbs with the single rear wheel (SRW). Both these figures are with 2WD configuration and with the 6.6L diesel engine, 4WD configuration is slightly less.

Max payload for the DRW is now 7,466 lbs and 4,493 lbs for the SRW. Both of these figures are with the 6.6L gasoline engine, the diesel is slightly less. So the moral of the story is that if you require towing capability buy the diesel. If you require payload capability, buy the gasoline engine.
