About the 2009 Acura RL

2nd generation (2005-2012), major mid-cycle refresh year

Acura positioned the RL as its technology-first flagship sedan: a quiet, comfortable luxury car with stronger all-weather handling than a traditional soft luxury sedan. Its core identity centers on SH-AWD traction, a high level of standard equipment, thoughtful cabin technology, and a polished interior. Against European rivals, the RL’s appeal was less about badge drama and more about secure handling, everyday usability, and a lot of built-in premium features.

The 2009 RL is Acura’s flagship sedan, with one well-equipped 3.5 trim that is actually powered by the new 3.7-liter V6. Standard highlights include all-wheel drive, heated leather seats, keyless access, xenon headlights, and a 10-speaker Bose surround-sound system with USB and Bluetooth audio.
