GM’s Turbo 6 Cylinder: Doubtful Fate?

Latest Intel: Project Deceased.

Rumors have been swirling that General Motors has been producing a brand-new turbocharged 6-cylinder engine tailored to its massively in-demand range of full-size SUVs and trucks, such as the Chevy Silverado and Tahoe. Unfortunately, the fate of this venture has now become uncertain.

CarBuzz reached out to GM for more information, in response to a report from GM Authority which suggested the discontinuation of the new engine. When asked to comment, the GM spokesperson simply stated: “We have no comment on this.”

“No comment” from the automaker in this case certainly seems to indicate that the project is, in fact, effectively dead. It’s not hard to understand why, given the company’s January 2021 pledge to pursue full electrification by 2035. Investing billions into the development of a new internal combustion engine (ICE) would go against the grain and be far more costly than finding other, more creative solutions to improve their current offerings.

Remember it is vital to recall that GM’s full-size pickups and SUVs offer considerable revenue which is being put towards R&D for electrification. That hasn’t and likely won’t change in the near future. Even if this is simply conjecture, GM could have come to a conclusion not to add a freshly designed turbo 6 since there are currently up to six other six-cylinder engines available.

It appears an updated motor is purportedly in the making and could be based on the 2.7-litre turbocharged four-cylinder featured on the Silverado and Sierra 1500s. Rumors suggest that it will be heavily adapted and if maximized, could deliver a formidable 310 horsepower and 348 lb.-ft. of torque.

Engineers at General Motors are working on a new engine for some serious horsepower. With expectations of around 500 hp and 500 lb-ft of torque, it stands to surpass the already impressive 472 hp and 445 lb-ft produced by the currently used twin-turbo V6 in the Cadillac CT4-V Blackwing. With this in mind, one may question why the automaker would bother creating another power plant capable of similar performance, unless fuel efficiency enhancements were also part of the agenda.

A potential response is the fresh-off-the-assembly-line Hurricane inline 6-cylinder engine from Stellantis. This cutting edge offering is sure to make waves in the automotive industry. The power it boasts along with its remarkable engineering is a testament to why it stands out among its competitors. The robustness of the engine guarantees durability, while its optimized design should lead to long-term fuel efficiency. Finally, all the advanced tech to help maintain and monitor performance levels puts it at the top of its class.

Available in either Standard Output or High Output configurations that produce horsepower ranging between 420 and 510, the engine is already being fitted in Jeep Wagoneer & Grand Wagoneer models as well as future designs of Alfa Romeo, Dodge, and Ram.

The Ford F-150 Raptor provides an impressive contrast; with a 3.5-liter twin-turbocharged V6 EcoBoost engine, it generates an output of 450 horse power and 510 lb-ft of torque. Do you follow our line of thinking?

The recent GM motor may have equaled or surpassed the production numbers of several central adversaries. However, that is not a compelling enough rationale to reconcile the financial outlay. Earlier this month, we identified all freshmen inline-six gas powered engines coming onto the market, and GM sadly wasn’t included.

It is improbable that the situation will alter in the forseeable future, potentially being unneeded as it stands.
