2010 GMC Yukon Denali Hybrid - Click above for high-res image gallery General Motors has finally added the 2-Mode Hybrid powertrain to its top-level GMC Yukon Denali. There aren’t any mechanical changes to the drivetrain that’s been available since 2008 in the standard-grade Yukon Hybrid and its platform mates, the Chevrolet Tahoe Hybrid and Cadillac Escalade Hybrid, which means we’ll see a 6.0-liter Vortec V8 engine with 332 horsepower and 367 lb-ft of torque and up to a 6,200-pound towing capacity. The hybrid technology is mostly contained in the 2-Mode Electrically Variable Transmission, which features twin electric motors powered by a 300-volt nickel metal hydride battery pack
