A new 6.6-liter V8 engine from General Motors could power at least 10 commercial trucks.

We already knew that this new V8 was bound for the all-new, eagerly awaited 2020 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks.

Now, it appears that it will end up powering several other heavy vehicles as well:

  • 2020 Chevrolet Silverado Medium Duty trucks (4500HD, 5500HD, and 6500HD)
  • 2020 Chevrolet Low Cab Forward (6500 Series)
  • Isuzu F Series 6500
  • Navistar International CV Series

GM is reportedly in the final stages of developing and testing this new engine, with the help of its partner Navistar.

Dare to Compare: Should you buy the Ford F-150 or the Chevy Silverado 1500?

GM’s new V8 is expected to debut on the 2020 Chevy Silverado HD

This powerplant is likely to feature technologies like direct injection, a low-friction valve train, and cylinder deactivation to boost its efficiency and capability. It’s expected to deliver about 400 horsepower and 450 lb-ft of torque.

The new 6.6-liter V8 will take the place of the current Silverado and Sierra HD engine, a 6.0-liter Vortec V8 that gets 360 horsepower and 380 lb-ft of torque. The new V8 will represent an additional option for the larger trucks mentioned above, which are now available only with turbo-diesel engines.

The new 2020 Silverado and Sierra HD models are expected to come out sometime toward the middle of 2019. That’s where we’ll probably get our first look at the new V8, with the other trucks following at a later date.
