The auto industry’s transition to electrical autos hasn’t particularly stopped gasoline motor growth. Even however the foreseeable future may well be electric powered, gasoline engines will even now be about for a long time, and automakers are continue to trying to build new, additional effective inner-combustion powerplants Evidently, at the very least one particular of these has gotten the axe: GM Authority experiences that General Motors has canceled development of an all-new turbocharged straight-6 engine which is been rumored for some time.
Last 12 months, it was noted that this new straight-six motor was in the scheduling levels. It was recommended that it would be crafted from the 2.7-liter turbocharged inline-four at the moment made use of in sure trims of the full-measurement Chevy Silverado / GMC Sierra as effectively as the all-new Chevy Colorado and approaching upcoming-gen GMC Canyon. That engine tends to make 237 hp in primary tune, or 310 hp in substantial-output trim in the Colorado.
This straight-six evidently would have made all those numbers pale in comparison. Sources say that GM was capturing for 500 hp and 500 lb-ft of torque. Those people numbers would have outgunned both of those of GM’s compact-block V8 truck engines, the 5.3-liter and the 6.2-liter. As the rumor goes, the straight-6 would have noticed duty in GM’s full-dimension pickups as properly as their SUV variants, particularly the Tahoe, Suburban, Yukon and Escalade.
When arrived at by Jalopnik, a GM representative would not confirm that the turbo straight-6 had ever been underneath growth, and would not remark on the rumor that it had been canceled.
If the rumored motor has actually been axed for great, GM may well come to regret that selection. Competing vehicles and SUVs from Ford, Stellantis and Toyota have all extra turbocharged 6-cylinder alternatives lately. The Toyota Sequoia at present provides a twin-turbo hybrid V6 Ford has been making use of Ecoboost V6s in the F-150, Expedition and Navigator for several years and Stellantis offers the Jeep Wagoneer with a new 3.-liter 510-hp twin-turbo straight 6.
Prospective buyers seeking something new or distinctive in their GM body-on-frame models might now have to wait until eventually the Standard unveils its next generation of small block V8s, or go with the company’s 3.-liter Duramax turbodiesel. In a way, it’s a disgrace — with people rumored specs, GM’s straight-six motor could have easily been competitive with the greatest boosted sixes on the current market nowadays.
