Which new big turbo-diesel truck is quicker? We put a new 2020 GMC Sierra 3500 dually 4×4 and a 2020 Ford F-350 4×4 together a bit of friendly drag racing and 0-60 MPH.
You knew we had to do this comparison sooner or later! These two trucks are new or thoroughly updated.
The 2020 GMC Sierra HD keeps its 6.6-liter Duramax V8 diesel from the before. It’s rated at 445 hp and 910 lb-ft of torque. The engine is mated to an all-new 10-speed Allison branded automatic transmission. This truck uses a 3.42 rear axle ratio.
The 2020 Ford F-350 is equipped with a redesigned 6.7-liter Power Stroke V8 that uses new piston design, new turbocharged, new fuel system and more. This engine is now rated at 475 hp and 1,050 lb-feet of torque. This engine is mated to an all-new Ford 10-speed automatic. The Ford is equipped with a 3.55 rear end.
We measured the GMC 3500 HD diesel dually at 8.66 sec 0-60 MPH. This is at the IMI Motorsports part, which is about 1-mile above sea level.
Spoiler Alert:
The GMC clocked in a 8.66 seconds 0-60 MPH run.
The Ford did an impressive 7.75 seconds 0-60 MPH.
