The Acura line-up receives a considerable revitalization for the 2009 model year with redesigned sedans. Topped by the flagship RL model, 2009 introduces new styling in addition to some mechanical upgrades. A 300-horsepower, 3.7-liter V-6 engine propels the 2009 Acura RL riding on a revised suspension. The Acura TL as well as entry-level focused TSX are all-new coming with longer and wider. Equipped with more powerful 280-horsepower engine, Super Handling All-Wheel Drive is now available on the Acura TL for 2009. Every 2009 model year Acura sedan will wear the brand`s new `power plenum` grille. While massive changes have been made to the sedan, Acura's MDX and RDX luxury utility vehicles are left unchanged.
