DEARBORN, MI - The 2011 Ford Explorer equipped with an optional 2.0L EcoBoost I-4 engine will be the new class leader in the mid-size SUV segment, achieving at least a 30-percent increase in fuel efficiency compared with the current V-6-powered Explorer.
"The all-new Explorer will give a huge universe of existing and prospective customers the capability they expect and the luxury and convenience they want, all combined with the fuel economy they need," said Mark Fields, Ford president of The Americas.
The new Explorer, which arrives in showrooms later this year, has a reduced vehicle weight compared to the previous model. Extensive use of lighter and stronger high-strength steels such as boron add durability while saving weight. An aluminum hood is used, while a one-piece composite front bolster - the radiator support between engine and grille - is 65 percent lighter.
Sophisticated engine controls and other technologies contribute to the Explorer's improved fuel economy. Electric power-assisted steering, battery management, fast engine warm-up and aggressive deceleration fuel shutoff all combine to improve drive dynamics and save fuel. The Explorer also features the first North American Ford application of a variable-displacement air conditioning compressor that reduces parasitic engine drag.
Powertrain advancements such as twin independent variable camshaft timing and six-speed automatic transmissions help Explorer deliver responsive performance when needed combined with low-rpm efficiency when cruising.
The EcoBoost I-4 engine pairs a turbocharger with direct gasoline injection to provide drivers with projected class-leading fuel economy - pending EPA certification - with no compromise in performance, according to the automaker.
