Further honing its already quite capable MDX, Acura has made a number of key improvements for 2003. First up is a 20-horsepower boost, giving the MDX a total of 260. To support the increased power, there's a revised five-speed automatic transmission, a new stability control system, a strengthened chassis, a retuned suspension and stronger brakes. Inside, the optional navigation system has gained voice recognition capability, enhanced graphics and expanded database coverage. There's also a tailgate-mounted rearview camera this year that transmits its view to the display screen when the vehicle is put in reverse. Lastly, Acura will be offering an optional DVD-based entertainment system as a factory option.
