FLINT, Michigan — General Motors Co. is "very confident" in newly designed V-8 engines for its reimagined light-duty pickup truck lineup after being dogged by engine recalls last year.

GM's new L76 5.7-liter and L78 6.6-liter V-8 engines will outfit the light-duty versions of the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500, high-selling and profit-rich models for the Detroit automaker.

"This architecture is the foundation for a lot of performance applications," said Norman Peralta, executive chief engineer of GM global electrical propulsion systems. "That does not happen if you don't have a robust engine family. So we're very confident."

The architecture of the small-block engines that power new GM light-duty trucks is also used in the 2027 Corvette Stingray, Grand Sport and Grand Sport X.

GM is rolling out revamped engines, years in the making, after recalling nearly 600,000 trucks and SUVs fitted with its L87 6.2-liter engines for potential failure last year, attributing the issue to a supplier.

GM directed dealers to check the engines of affected vehicles. If the engine passed testing, GM recommended switching to thicker engine oil. Faulty engines were replaced.

"For us, foundationally, we're going to stand by our customers," Peralta told reporters at a Wednesday briefing at Flint Engine Operations. "It's all about customer safety and customer satisfaction, and that's why for those customers, we've got a 10-year, 150,000 (mile) special coverage.

But "this new architecture is a brand new agent architecture," he added.

"It's a new lubrication system. It's a new fuel system. New heads," Peralta said. "I can go on and on."
