### Performance and Powertrain

At the heart of the 2018 GMC Yukon XL Denali lies the formidable EcoTec3 6.2-liter V8 engine, a powerhouse engineered for both strength and efficiency. This naturally aspirated V8 produces an impressive 420 horsepower and 460 pound-feet of torque, enabling the Yukon XL Denali to confidently tow substantial trailers, accelerate smoothly, and handle diverse driving conditions with ease.
