All-new Acura MDX Prototype made its world debut at the 2013 North American International Auto Show in Detroit.
Adopting a front grille and Jewel Eye LED headlights that represent the next-generation design of the Acura brand, the Acura MDX Prototype expresses a smooth and elegant form that provides a sense of flowing air. Although the vehicle height was successfully lowered by 1.5 inches, a spacious interior equivalent to the current model was secured through highly-efficient packaging.
The new MDX achieves both high torque and excellent fuel economy with an all-new 3.5L direct-injected SOHC i-VTEC V6 engine. Acceleration performance and driving comfort appropriate for a luxury SUV were also realized through fully refurbished front and rear suspensions and a lightweight chassis.
Acura plans to produce the all-new 2014 MDX at its Alabama plant and introduce it to the U.S. market by mid-2013.
