The Acura RL is a mid-size luxury car that was manufactured by the Acura division of Honda for the 1996–2012 model years over two generations. The RL was the flagship of the marque, having succeeded the Acura Legend, and was replaced in 2013 by the Acura RLX. All models of the Legend, RL and RLX lines have been adapted from the Japanese domestic market Honda Legend. The model name „RL” is an abbreviation for „Refined Luxury.”
The first-generation Acura RL was a rebadged version of the third-generation Honda Legend, and was first introduced to the North American market in 1996, to replace the second-generation Acura Legend.
The second-generation Acura RL was a rebadged version of the fourth-generation Honda Legend, introduced to the North American market in September 2004, as a 2005 model. This iteration of the RL received an extensive mid-generational facelift for the 2009 model year, and a further update for 2011.
The third-generation debuted for the 2014 model year as the Acura RLX.
