This not only helps the engine warm up quickly, but also maintains an ideal temperature for performance and minimizes fuel consumption. The 3.0L Duramax includes several new features that all work in harmony to increase power, reduce friction and increase efficiency.Īctive Thermal Management targets specific areas of the powertrain system for heating and cooling. It’s a win-win design that offers fuel economy and smooth operation.” Fewer parts mean less weight and friction and enhanced efficiency. “The result is we don’t need balance shafts and the engine only has one set of overhead cams (compared with two sets in a V6). “The inline six is a naturally balanced engine,” Barta points out. The 3.0L Duramax diesel inline-six engine design lends itself to efficiency. “It was an epic 6,200-mile drive to Fairbanks from our Michigan Proving Grounds, and we found what we were looking for, minus 20 degrees Fahrenheit.”

“In October 2018, our verification team drove eight development trucks to Fairbanks, Alaska, to find freezing temperatures and validate our diesel exhaust fluid systems prior to the upcoming winter season,” Barta says. To help test the durability, GMC seeks out nature’s extremes - going to Death Valley at the hottest times of the year, north to Canada at the coldest times of the year and to many of the highest elevations that a customer can drive in North America. “More than five round-trips to the moon!” “We logged well over 2.5 million on-road miles specifically with the 3.0L Duramax,” Barta recalls. was there as it was developed and tested, and tested some more. “We delivered on those targets with outstanding fuel economy, best-in-class 277 horsepower † and great throttle response.”īarta - a member of the team that created this new engine being built in Flint, Mich. “The 3.0L Duramax was designed to be a ‘no excuses’ engine option that offers excellent fuel efficiency, great low-end torque and smooth responsive operation,' Assistant Chief Engineer John Barta states. †, the newest Duramax offers - everything truck owners want - capability, power and efficiency. of torque, 277 hp and a max towing capability of 9,000 lbs.

Diesel engines are known for their efficiency and durability, but when you’re talking about the 2020 Sierra 1500 pickup truck’s available 3.0L Duramax Turbo-Diesel engine, that’s just the beginning.
