1996-2004

In 1996, Acura introduced the Acura 3.5RL (internally known as “KA9”) to replace the Legend, as market research indicated that consumers referred to Acura products by their model names rather than associating them with the Acura brand. The 3.5RL featured a unique longitudinally mounted V6 engine, allowing for a smaller turning radius and better maneuverability in city driving, with a 56/44 front/rear weight distribution. In late 1998, the 1999 3.5RL underwent a facelift with integrated foglights, revised bumpers and hood, and side-impact airbags. Over the years, updates included a more extensive navigation system screen, DVD map databases, engine improvements resulting in 225 hp and 231 lb-ft of torque, and interior enhancements. The 2004 3.5RL was the first production saloon car to offer satellite radio as standard equipment and marked the end of Acura’s use of numeric engine displacement designations.
