Frankly, it’s about time Acura adopted the use of a turbocharger. We’ve driven the high-revving TSX sedan and RSX hatch, the 300-horsepower (now SAE rated at 290 horses) RL flagship, and the MDX SUV, all of which felt competent but hardly thrilling in the power department. Even the NSX, with between 252 and 290 horses, lacked the underhood goods to match its supercar exterior. Of them all, the TL sedan has been the only Acura offering with an appropriate balance of horsepower and torque. The 2007 RDX, with 240 ponies and 260 lb.-ft. of twist, will trump the rest of Acura’s lineup. Plus, it fills a void for the brand, and offers a premium alternative to models like the 2007 Toyota RAV4 and the 2007 Hyundai Santa Fe.
