It comes as no surprise that gas mileage has never been one of the Cadillac Escalade’s strong suits. Over the years, the Escalade’s gas mileage has never exceeded 20 miles per gallon (MPG) on the highway, while its city mileage has dwelt in the low teens. Get ready for a magic makeover for one of America’s most indulgent gas hogs. All that changes with the brand new 2009 Escalade Hybrid, which promises a whopping fifty percent improvement in city mileage.
The 2009 Escalade Hybrid’s 2-Mode Hybrid system mates a special transmission and battery pack to the big 6.0 liter V-8 to deliver 20 city and 21 highway MPG. At low speeds, the Escalade Hybrid can be propelled solely under electric power. At higher speeds, the gasoline engine and electric motor work in tandem. When you really put your foot in it, the gasoline engine takes over. Active Fuel Management shuts down half of the V-8’s cylinders under light loads to achive better gas mileage while cruising at highway speeds. Auto engine shut off turns the gasoline engine off when the Escalade Hybrid is stopped, saving additional fuel.
