The RLX can be viewed as a large midsize sedan or a small full-size one. As such, it’s not much different from the RL — last sold as a 2012 model — which it succeeds. Compare the RLX, the RL and the current Acura TL midsize sedan side-by-side.
The RLX is closer in size to a Buick LaCrosse or Volvo S80 than to such flagship luxury cars as the BMW 7 Series, Jaguar XJ, Lexus LS and Mercedes-Benz S-Class. Acura says it compares to midsize luxury sedans like the BMW 5 Series and Lexus GS, to which it’s more closely priced.
Typical of Acuras, the RLX technically comes in one trim level but with a choice of option packages that essentially serve as trim levels, as most of them include a host of unrelated features. The Navigation Package is an exception, as it includes only navigation. There are also Technology, Krell and Advance packages. Krell is the name of a little-known, high-end audio manufacturer that designed the higher of two optional premium stereos. (The more affordable Technology Package includes an ELS premium audio system that’s an upgrade over the base RLX stereo, which is also branded ELS.)
