N/A Gasoline vs. Turbo Diesel: Which 2020 Chevy Silverado 2500 HD Is Quicker?

The 2020 Silverado HD is much obliged to offer two rather interesting engine options. On the naturally aspirated front, the 6.6-liter V8 with LT1 know-how should be more than enough for daily driving. As for towing capacity, you can’t go wrong with the 6.6-liter Duramax.

More than $10,000 separate the two engine choices in the case of the Silverado 2500 HD, and that’s a lot of hard-earned bucks when you think about it. Looking at the bigger picture, the turbo diesel is more expensive because of the 10-speed automatic transmission instead of the 6-speed in the gasoline V8 as well as 910 pound-feet of torque from 1,600 rpm.

There are differences with the rear axle ratio as well, namely 3.73 for the DI VVT gasoline option and 3.42 for the Duramax-branded workhorse. To better understand what this means in terms of acceleration off the line, higher gearing translates to better acceleration while lower gearing suits the lower revolutions and higher fuel efficiency of the turbo diesel engine.

You might think the gasoline V8 is quicker off the line, but The Fast Lane Truck has some news for you. Running the trucks in 2WD to 60 miles per hour, the Silverado 2500 HD finished the acceleration test in 8.00 and 9.05 seconds, respetively. The diesel-engined pickup also happens to be quicker to 60 in 4WD, namely 7.90 as opposed to 9.22 seconds.

It’s hard to believe the L8T pushrod V8 can’t match the L5P in the 0-to-60 test, but then again, the six-speeder is the biggest offender as far as we can tell. Something else worth highlighting is the torque, almost half the amount of pound-feet compared to the more expensive option.

In this segment, however, Ford has the better gasoline V8 in the 2020 Super Duty. The 7.3-liter Godzilla is one hell of a powerplant, designed to be as durable and reliable as possible without cutting back on capability and fuel economy.
