Twin-turbo six-cylinder engine could land in GM pickups and SUVs
Will General Motors follow the lead of its major competitors by introducing a twin-turbocharged six-cylinder gasoline engine in its full-size pickups and SUVs? It looks like it.
While the decision is far from final, GM Authority reports that the automaker is currently considering the development of such an engine. It would be similar to the 2.7-liter turbocharged four-cylinder available in the Chevrolet Silverado 1500 and GMC Sierra 1500.
Other options under the hood of these trucks at the moment include naturally aspirated 5.3- and 6.2-liter V8 engines and a 3.0-liter turbodiesel V6.

Ford has long offered EcoBoost V6 engines ranging in displacement from 2.7 to 3.5 liters, while Stellantis recently introduced the new Hurricane engine for the Jeep Wagoneer and Grand Wagoneer. We’ll see it in the Ram 1500 sooner or later, too.
Oh, and let’s not forget the Toyota Tundra, whose latest generation ditched the old V8 for a 3.5-liter twin-turbo V6.

GM already offers twin-turbo V6 engines, but only in Cadillac cars. There is the 3.0 liter unit in the CT5 and CT5-V as well as the 3.6 liter variant in the CT4-V Blackwing. This is a logical solution for select Chevrolet and GMC pickups and SUVs, not to mention of course the Cadillac Escalade.
Continued development of GM’s V8 lineup is another possibility, but as GM Authority Remarks, when you have a 2.7-liter turbocharged four-cylinder that generates almost as much torque as the naturally aspirated 6.2-liter V8 (420 lb-ft versus 460 lb-ft), that seems questionable.
