The Acura MDX offers an outstanding V6 powertrain, seven-passenger seating and a standard four-wheel-drive system that prevents skids almost before they happen. Neat styling, attention to detail, excellent crash protection and competitive pricing increase the appeal of this luxury SUV. Introduced in 2001, MDX was named North American Truck of the Year by a panel of 50 independent automotive journalists. Through the four model years since, the MDX has been steadily improved in all areas. The body has grown more rigid, allowing better vibration control and a smoother ride. Power has increased, and a more compact five-speed automatic transmission shifts even more smoothly than before. MDX's standard VTM-4 four-wheel drive system has been remapped to work seamlessly with a new Vehicle Stability Assist (VSA) system to improve handling on slippery surfaces and to enhance stability in all conditions. Acura has updated the optional navigation system and added a rearview camera that engages when the transmission is in reverse. A DVD entertainment system with wireless infrared headphones is now available. For 2004, MDX gets another round of updates. This is what the auto industry calls a mid-cycle revision, and the improvements are as extensive as any undertaken so far. Horsepower and torque increase, thanks to a new dual-exhaust system. The 2004 MDX sports new front- and rear-end styling, redesigned alloy wheels, a new Side Curtain Airbag system that helps to protect occupants in all three rows, and interior upgrades that include enhanced interior lighting with ambient footlights and entry illumination. In short, the attributes that earned MDX awards remain and have been refined. This so-called luxury SUV remains one of the best values in the class.
