From Acura press: The 2007 MDX is equally daring in its styling and thorough in its safety and environmental responsibilities. Included as standard equipment is the largest array of passive safety features in Acura history. The MDX's class-leading 300-hp VTEC™ V-6 makes as much power as some competitive V-8s, yet delivers ultra-low emissions and excellent fuel economy. Inside the 7-passenger interior, the MDX offers thoughtful luxury and an unmatched range of advanced available technologies, including the Acura Navigation System and AcuraLink™ Satellite Communication System with real-time traffic and a spectacular 10-speaker Acura/ELS Surround™ Premium Sound System.
Altogether, the all-new 2007 MDX embodies Acura's commitment to performance, luxury, quality and style, together with parent company Honda's global mandate for safety and environmental care. The 2007 MDX is the sixth Acura project to be designed and engineered in the United States, including the 1997 CL, 1999 TL, 2001 CL, 2001 MDX, and 2004 TL, and several award-winning Honda products.
Given the new MDX's performance goals, its powertrain and driveline were required to advance on multiple fronts. The result is the most powerful normally aspirated 6-cylinder SUV powerplant currently available in America. In addition, the MDX returns competitive estimated fuel economy, and meets tough CARB LEV-2 ULEV emissions standards. To put the newfound power to the ground and provide agile, responsive handling, the MDX has standard Super-Handling All-Wheel Drive™ (SH-AWD™).
The MDX's sophisticated 3.7-liter VTEC® V-6 powerplant develops 300 horsepower at 6000 rpm and 275 lbs.-ft. of torque at 5000 rpm. That gives it the highest horsepower and torque output of any engine in the Acura lineup. The MDX returns an EPA 17/22 City/Highway mpg, placing it among the leaders of its SUV class.
Compared to the previous generation MDX, the new powerplant gained 47 horsepower and 25 lbs.-ft. of torque. Of that horsepower gain, 20 horsepower came from an increase in displacement and a new 11.0:1 compression ratio and 15 more horsepower are due to new intake port shape, valve design and VTEC® tuning. The final 12 horsepower is credited to the new MDX's high-flow induction and exhaust systems. Although more powerful, the engine is actually 17.2 pounds or 3.7% lighter than the engine it replaces and offers six percent more displacement. Durability upgrades throughout the powertrain, including a high capacity radiator with twin cooling fans and a standard transmission cooler accommodate the MDX's new 5000-pound tow rating.
