L87 Engine – The Power Core of Modern GM Trucks

At the heart of GM’s latest trucks lies the L87 engine, a 6.2-liter small-block V8 that embodies strength, precision, and advanced technology. Delivering a robust 420 horsepower and 460 lb-ft of torque, the L87 engine ensures top-tier performance for heavy-duty applications. It’s equipped with Dynamic Fuel Management, allowing seamless transitions between cylinder modes for better fuel economy. The direct injection system enhances throttle response, while variable valve timing ensures smooth acceleration across the rev range. The lightweight aluminum design keeps it efficient without sacrificing power. Ideal for towing, off-roading, and daily driving, the L87 engine maintains unmatched reliability. Found in flagship GM models like the Yukon Denali and Silverado Trail Boss, it delivers both refinement and power, proving that efficiency and muscle can coexist perfectly.
