Considerably updated both in design and under the hood, the 2009 Acura RL returns with a freshened balance of comfort and performance. The new, more powerful 3.7-liter V6 engine boosts total output to an impressive 300 horsepower. Despite an entry-level luxury price tag (starting at $46,680), the 2009 RL boasts significant amenities, including six airbags, dual-zone automatic climate control, sunroof and a precrash safety system. Upper-tier models add in technology features such as adaptive cruise control, voice-activated navigation with rearview camera and Acura's proprietary Collision Mitigation Braking System. Fuel efficiency is estimated at 22 mpg on the highway and warranty coverage comes in the form of a 4-year/50,000-mile basic package.
