Acura has a long history of concept cars that are near exact versions of the resulting production car. That is clearly evident in the 2014 RLX, Acura's biggest, most luxurious sedan. It was unveiled Wednesday at the Los Angeles Auto Show.

The RLX's V6 delivers 310 hp through the front wheels, while the Sport Hybrid Super Handling AWD system sends 370 hp to all four wheels. The wheels in the back, by the way, are driven by their own electric motors for a hybrid setup.

Acura is also giving the RLX a form of rear-wheel steering with a system named Precision All-Wheel Steer, which it cutely nicknames "P-AWS." Rear wheel angle varies from side to side, depending on how fast the car is being hustled. Acura says the system "provides enhanced vehicle stability, maneuverability and control."

At the New York auto show last spring, the RLX concept didn't have an interior. Now, the RLX has a meticulously finished, swooping interior that features two massive color screens. The lower one is touch activated, similar to the system in the new Honda Accord. It controls Acuralink infotainment system that accesses Internet radio services such as Pandora and Aha, real-time traffic and weather updates, and Acura's new Concierge service that delivers personalized navigation. Acura's ELS digital sound system is excellent, but for the first time there will be an audio system by Krell with 14 speakers.

The overall interior looks clean and uncluttered. There are fewer cramped, tiny buttons, for instance and almost every surface is covered in leather and wood. It's as close to traditional luxury as Acura is willing to get. The exterior is best described as understated.
