We’ve previously expressed in detail why the 2019 Silverado 1500 has so far refrained from moving the needle in the fuel economy department, even though there’s been no shortage of effort to make the new Chevy truck more fuel efficient. Despite losing 400 lbs, gaining the latest engine technology such as dynamic fuel management, improving aerodynamics, and adding a couple gears inside the transmission housing – EPA fuel economy moved by 1 mpg. While it’s true that fuel economy means little to the legions of light duty truck buyers, it does – or rather, it did – matter a lot to GM’s CAFE regulations formula.
However, we don’t see a long-term plan set in place just because the short-term outlook may be affected. GM has gone on record that it will hold fast on delivering 20 new electric vehicles by 2023, but whether the public bites or not will be a different story. This also means that trucks like the 2019 Silverado 1500 will continue to see fuel economy gains, also beyond whether consumers care or not.
For instance, the two most fuel efficient engines have yet to launch in the 2019 Silverado 1500. These are the 2.7L turbo four-cylinder engine, and the 3.0L LM2 inline-six diesel engine. While the diesel horsepower and torque specs have yet to be announced, the 2.7L L3B turbo gas engine will offer a potent 310 horsepower and 348 lb-ft of torque, while achieving a 0-60 sprint in under seven seconds. The L3B will mix into 2019 Silverado 1500 production starting November. Fuel economy hasn’t been announced yet, but we expect it to surpass what’s been observed so far.
The LM2 diesel engine is expected to launch early 2019, and it would need to come with at least 250 horsepower and 440 pound-feet of torque to match Ford’s new 3.0L PowerStroke in the 2019 F-150. The 3.0L LM2 diesel is also expected to be the most fuel efficient and capable engine offered in the entire 2019 Chevrolet Silverado 1500 lineup.
Pricing has yet to be announced for either powertrain upgrade.
