Yukon Denali's bold exterior styling holds true to Denali tradition. Attention to precision and detail is second to none, and helps Yukon's powerful-yet-elegant shape further stand apart in the full-size luxury segment.This detailing can be seen everywhere, from the accents on the standard 20-inch wheels, or even the standard HID projector-beam headlamps with signature LED accent lighting – but it's especially evident in Yukon Denali's newly redesigned grille. Yukon Denali continues to deliver great performance and capability, thanks in no small part to its powertrain. A 6.2-liter EcoTec3 V-8 is standard equipment on Yukon Denali, and offers 420 horsepower and 460 lb-ft of torque. Advanced features, including direct fuel injection variable valve timing, and Active Fuel Management enable the engine to optimize efficiency, yet provide peak performance when needed most. For 2018, Yukon Denali pairs that 6.2-liter V-8 with a new 10-speed automatic transmission. This new transmission offers a wider gear ratio spread than the previous eight-speed automatic transmission, allowing the 6.2-liter V-8 to remain within the "sweet spot" of the torque curve when upshifting. Additionally, the new transmission provides a lower numerical top gear ratio, which allows Yukon Denali's engine to run slower while cruising at highway speeds, helping improve efficiency.
