More specs are still on the way, but for now, Chevrolet says the new Silverado HD will come with two different engine and transmission combinations.
There's a new gas engine of unannounced cylinder count and a six-speed automatic transmission -- for context's sake, the current Silverado HD's gas engine is a 6.0-liter V8.
And then there's the tried-and-true Duramax diesel V8, which will send 910 pound-feet (!!!) of torque through a new Allison 10-speed automatic.
The 2020 Chevy Silverado HD goes on sale in mid-2019.
