From Acura press: The MDX had a stellar first year, establishing itself as the #1 SUV by capturing both the Motor Trend Sport Utility of the Year and the North American Truck of the Year awards. In the following years, Acura proceeded to make it even better, increasing its already formidable performance and further refining the MDX inside and out.
For 2003, a new engine boosted horsepower from 240 to 260, a new 5-speed automatic transmission was added and the chassis and suspension were enhanced to take advantage of the additional power. A new drive-by-wire throttle system was included and the state-of-the art VTM-4® four-wheel drive system was revised to provide enhanced vehicle control during acceleration, cornering and braking.
The 2004 model year MDX received exterior styling enhancements that gave it a muscular, performance-oriented look representative of its impressive powertrain. Last year, the MDX received a host of technological and safety upgrades, including standard XM® Satellite Radio, an enhanced optional Acura Navigation System with Voice Recognition™ and the addition of the OnStar system and HandsFreeLink™ wireless phone interface on the Touring Package. Standard safety features such as an improved Vehicle Stability Assist (VSA®) system and Brake Assist, which helps drivers apply full braking pressure in an accident avoidance situation were added to the 2005 MDX.
For the 2006 model year, the MDX receives an assortment of stylish and sporty additions to the interior. High quality ebony-colored Zebra wood garnishes the center console and door switches and refined Satin Chrome accents are added to models equipped with the Touring Package. The MDX also adds a new exterior color, Amazon Green Metallic.
An advanced powertrain is essential to meet the MDX's goals of providing V-8-like performance, class-leading low emissions, and excellent fuel economy. To that end, the MDX is powered by an advanced 3.5-liter, VTEC V-6 engine. The MDX powerplant produces 253 horsepower SAE net (8/04)at 5800 rpm, and 250 lb-ft SAE net (8/04) of torque at 3500 rpm. Acura's Variable Valve Timing and Lift Electronic Control (VTEC™) valvetrain, first used in the NSX supercar, adjusts the timing, duration, and lift of the intake valves according to engine speed. In conjunction with a two-stage intake manifold, VTEC yields muscular response at low- and medium-rpm, high peak-rpm performance, very low emissions, and superior fuel efficiency. A dual exhaust system increases horsepower and torque while helping to minimize emissions.
