After a major refresh in 2009, there's not much new in the RL for 2011. The most notable change is the addition of a new 6-speed transmission, as well as a revised front grille. In addition, Acura has also fitted the 2011 RL with Hemholz resonators in the wheels, which in turn help reduce vibration and interior noise. The RL achieved 5-star ratings in all NHTSA crash tests, including the rollover test. Acura claims it's the only luxury automaker to do so.
Standard all-wheel drive stabilizes the car around corners, which is a nice thing to know with the 3.7L V6 under the hood. This is the kind of Acura technology that has earned the RL reviews for being quiet and surefooted, as well as quick and refined. The luxurious interior is very well insulated, and the Bose sound system adapts its volume to the speed of the vehicle.

In order to achieve such stellar crash test results, the RL features a wealth of safety features on board. Anti-lock brakes, stability assist, six air bags and tire pressure monitoring all come with the car. An active front lighting system that projects the beams around curves is optional. So is the Collision Mitigation Braking System, which uses a radar signal mounted behind the front grille to lessen the impact of a collision by preemptively slowing the vehicle. The CMBS/ACC Package comes with adaptive cruise control, which allows you to select a long, medium or short distance from the car in front, which the RL will hold with the throttle and brakes, unaided by the driver.
