At the 2012 New York Auto Show, Acura revealed the new RLX, which may carry a concept moniker, but we all know that it's a thinly disguised version of the production model slated for launch in North America at the beginning of 2013.
The RLX will replace the RL as Acura's flagship model in a segment that the company has constantly failed to deliver.
The Japanese brand's full-size sedan has approximately the same length as the current RL, but comes with a two-inch longer wheelbase and two-inch shorter front overhang, while both the track and vehicle width increase by around two inches.
The styling builds on Acura's so-called 'Keen Edge' design motif, as seen on the smaller ILX. The concept's stance is accentuated by a set of 20-inch forged aluminum wheels shod in 255/35 R20 high-performance tires, which is probably one of the few elements on the concept that won't make it into production.
The most intriguing aspect of the concept is hidden from view under the car's hood as the RLX features the first application of Acura's new Sport Hybrid SH-AWD. The system links a new 3.5-liter direct-injected VTEC V6 engine to a 7-speed dual clutch transmission and three electric motors, generating a combined out of more than 370-horsepower.
According to Acura, the RLX Sport Hybrid SH-AWD returns an estimated combined fuel economy of 30mpg (equal to 7.8lt/100km and 36.0mpg UK).
Acura revealed that the production 2013 RLX will also be offered in a 310-horsepower, front-wheel-drive version.
"We have created a true luxury sedan based on our Acura DNA," commented Tetsuo Iwamura, American Honda CEO.
"This means achieving advanced performance through engineering efficiency to create a unique synergy between the vehicle and its driver. Inside and out, on the open road or city streets, the sophisticated and elegant Acura RLX will offer a level of connectivity, comfort and advanced performance demanded by today's luxury buyers," he added.
