The GMC Sierra 1500 has a number of engine options available for the 2020 model year, including the new Duramax 3.0-liter Turbo-Diesel engine. This motor nicely balances power with fuel-efficiency.
Power and capability
The Duramax Turbo-Diesel engine connects with a 10-speed automatic transmission to achieve 277 horsepower and 460 lb-ft of torque. As such, the available engine allows you to have smooth drives on adventures both on and off the road.
When properly equipped, the four-wheel model can haul a maximum payload of 1,830 pounds and tow up to 9,100 pounds. While in Tow/Haul mode, the exhaust brake and transmission can help you maintain stability when traversing steep hills.
When you opt for the two-wheel-drive model, the engine gets an EPA-estimated 23 mpg in the city and 30 mpg on the highway.* The engine can accordingly help you save money on fuel over time. In addition, its block is comprised of lightweight cast aluminum alloy, which leads to a 25 percent savings in mass when compared to a cast-iron engine block.
The Turbo-Diesel engine utilizes start/stop technology so that the engine can turn off when you’re at a red light. Active Thermal Management helps the engine stay at the optimal temperature to further reduce fuel consumption.
