GM Fires New V-8 Salvo in 2027 Truck Wars Against Ford and Ram

General Motors on Thursday detailed an engine lineup for its 2027 Chevrolet Silverado 1500 and GMC Sierra 1500 that includes two new V-8 engines, a carryover inline-six diesel and an enhanced four-cylinder turbo — a direct challenge to Ford and Ram in the revived "truck wars" of the Motor City.

The announcement follows a parallel move by Ford Motor, which also updated its engine offerings for the 2027 model year. Ram, meanwhile, is touting the return of its Hemi V-8 engines, including new performance "muscle trucks."

GM executives said they expect the upgraded engines and redesigned pickups to extend the automaker's six consecutive years of sales leadership in the full-size truck segment over competitors including Ford and Chrysler parent Stellantis.

"If we don't stomp the competition with these trucks, then I'd be very sad and questioning myself. That's the goal," GM President Mark Reuss said during a media event Wednesday at the automaker's Flint Engine plant near Detroit. "That's what success looks like: continued truck leadership."

V-8s still pay the bills

While Ford's F-Series remains the top-selling full-size truck and brand, Chevrolet and GMC combined have outsold Ford since 2020. Ford has previously said its F-Series business generates more revenue than many Fortune 100 companies. Full-size trucks — light-duty models and larger variants — fund U.S. automakers' investments in emerging markets and technologies.

The V-8 revival comes as the Trump administration removes federal support of up to $7,500 in EV purchase incentives and moves to reduce or eliminate federal fuel economy rules and penalties. GM said its decision to build a new generation of V-8s predates those regulatory changes; development of its Gen 6 small-block engine started in 2018.

"This is history today and we don't take that lightly," Reuss said of the launch, which marks GM's sixth generation of small-block V-8 engines, a product line the company first produced in 1955.

Why customers still want eight cylinders

Many automakers dropped V-8 options amid tougher fuel economy standards, but the engines continue to sell well in pickups because of their towing and hauling capability. Analysts said all-electric pickups have sold poorly in part because towing and hauling significantly reduce an EV's range.

Pickups have also stayed out of the hybrid boom. Toyota Motor reports only 18.7% of its Tundra full-size pickup sales this year have been hybrids.

GM backs the pattern with its own numbers. V-8 models account for 55% of Chevy Silverado sales this year and roughly 61% for the GMC Sierra 1500. The 3.0-liter TurboMax diesel represents 35% of Silverado 1500 sales and 20% for the Sierra 1500.

"No one has the efficiency on a diesel that we have," Reuss said. "So if you look at the performance efficiency, but also in raw performance and range, hybrids don't do it. … At the end of the day, we have focused on something that the customer wants, and that's what we have here."

Ram offers the cautionary tale. When it dropped its Hemi V-8 for a more efficient inline six-cylinder, sales suffered enough that the brand announced plans last year to resurrect the engine. Supplies remain tight.

"Ram showed that you can lose buyers by not having [V-8 engines] available," said Stephanie Brinley, associate director of Mobility Global's AutoIntelligence. "Part of it is because of that expectation that there is something that the V-8 is better at."

A contested scoreboard

Full-size pickups have led new U.S. vehicle sales for decades. Ford's F-Series claims to be the top-selling vehicle since 1981, with the Silverado typically at No. 2, Ram close behind and the GMC Sierra fluctuating within the top 10.

GM's gains against Ford come as Ford battles production issues from supplier fires over the past year. Through the first half of this year, Sierra sales were flat while Silverado fell 4.6%. Ram rose 19%, and the F-Series declined 13%.

Pickup buyers rank among the most loyal customers in the U.S. auto industry. Mobility Global, formerly S&P Global Mobility, reported last year that the Silverado 1500, F-150 and Ram 1500 regularly rank among U.S. vehicles with the highest brand loyalty — though loyalty can dip when automakers change products or face recall issues.

GM has one of its own. The National Highway Traffic Safety Administration opened an investigation into GM's current 6.2-liter V-8 over continued failures, even after the automaker recalled and said it had fixed engine issues. Norman Peralta, GM executive chief engineer of global engines and battery systems, said the company is cooperating with NHTSA and is "very confident" the new engines will not have similar problems.

With EV demand lackluster and federal incentives gone, the 2027 truck war will be fought largely with gasoline engines — and the Detroit Three's profitability depends on who wins it.
