Like every engine in the Gen V Small Block engine family, the new 6.2L L86 offers more power and higher efficiency than its predecessors thanks to a trio of technologies, including direct injection, active fuel management and variable valve timing. As such, the L86 is estimated to produce 420 horsepower and 450 lb-ft of torque — the most power and torque of any light duty truck engine. In the 2014 Sierra and 2014 Silverado, the powerplant is expected to deliver a class-leading maximum trailering capacity of 12,000 pounds.
The 6.2L L86 will be available in the 2014 Sierra Denali and SLT, certain trim levels of the 2014 Chevy Silverado, and some of GM’s all-new SUVs based on the K2XX vehicle architecture.
Final SAE-rated power and torque numbers will be available later this year, but if the Corvette’s 6.2L LT1 (that’s very similar to the L86) is any indication, there’s a good chance GM is playing it safe with the 420/450 figures.
