GM 6.2 Liter V8 EcoTec3 L87 Engine
The L87 is a 6.2-liter, eight-cylinder engine from General Motors that’s used in a range of pickup trucks and SUVs. Featuring an OverHead Valve (OHV), or “push-rod” design in a “V” configuration, the L87 is part of GM’s Gen V Small Block engine architecture that’s known in trucks and SUVs as EcoTec3.
The L87 is part of the second-generation EcoTec3 engine family, and is the direct successor to the GM L86 engine. It was first launched in the all-new 2019 Silverado 1500 (fourth generation) and 2019 Sierra 1500 (fourth generation).
|Displacement:||6.2L / 376 cu. in.|
|Vehicles:||Chevy Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, Yukon XL, Cadillac Escalade|
|Introduced:||2019 model year|
|Predecessor:||L86/ Gen 3 Small Block|
The 6.2L with DFM — the largest and most powerful gas V-8 in the segment — is SAE-certified at 420 horsepower (313 kW) and 460 lb-ft of torque (623 Nm) and is paired with a Hydra-Matic 10-speed automatic transmission.
“The increased variability of Dynamic Fuel Management means the engine will operate more often with a reduced number of cylinders, which saves fuel across the board,” said Lee. “Better yet, the transitions are transparent, and because the system is torque-based, you’ve always got that satisfying feeling of power on demand that comes from Chevy’s Gen V Small Block V-8 engines.”
The engines also feature driver-selectable stop/start technology that helps save fuel in stop-and-go traffic. The 6.2-liter L87 was initially offered in LTZ and High Country models.
Notably, the 6.2-liter L87 earned recognition as one of Wards 10 Best Engines in 2018. For the competition, WardsAuto editors evaluated every all-new or significantly improved engine or electric propulsion system available in production vehicles in the U.S. Vehicles must have had a starting MSRP less than $64,000, with the editors scoring eligible vehicles on horsepower, torque, technology, observed fuel economy, relative competitiveness and noise characteristics.
