Exterior
GM says the Yukon Hybrid's exterior changes are intended to make the SUV more aerodynamic compared with the gas-powered Yukon.
A modified bumper drops the regular Yukon's fog lights for some chunky bodywork and two small portals. There are horizontal grille slats and lower side cladding. Exterior features include:
Standard 18-inch wheels
Denali has 22-inch wheels
Assist steps
Heated power mirrors (auto-dimming on driver's side)
Low-rolling-resistance tires
