The Sierra HD benefits from the same type of enhancements as the Silverado HD. The 6.6-litre Duramax turbo-diesel engine gets a boost to 470 horsepower, while the 401-horsepower 6.6-litre gasoline V8 is now mated to a 10-speed Allison automatic transmission. The cabin has also been revised for 2024, with the dashboard now incorporating a 13.4-inch touchscreen. The new Sierra HD AT4X model provides increased off-road capability with DSSV shocks from acclaimed Canadian company Multimatic.
