The RL gets a minor freshening with new front-end styling, new taillights, improved interior trim, and a 6-speed automatic transmission (in place of last year's 5-speed) which boosts EPA fuel economy estimates to 17 MPG city/24 highway (up from 16/22). The RL gets better sound insulation and an industry-first "quiet wheel" that reduces resonance inside the tire to diminish road noise.2011 Acura RL
