Looking to bridge the gap between mid-size and full-size luxury sedans, Acura has unveiled its new RLX flagship model at the Los Angeles Auto Show today.
In an outer shell thatís more 5 Series or E-Class, Acura has fitted an interior it says is more in keeping with the 7 Series or S-Class, boasting the most rear-seat legroom in its class at 38.8-inches, a solid three inches more than the BMW 5 Series, Audi A6 and Lexus GS. In addition, Acura also claims the most front and rear should room of its competitors. Similar in overall length to the RL it replaces, the RLX has a two-inch longer wheelbase and is two-inches wider overall.
Looking in many respects like a larger ILX, the RLX is less than dramatic and easily recognizable as an Acura. Fitted with 18-inch wheels as standard, 19s will come equipped on higher-grade trim levels, while LED headlights should help add some drama to the carís approach.
Powering the new flagship is familiar Acura equipment, though with changes. A 3.5-liter V6 engine gains direct injection to deliver 310 hp and 272 lb-ft of torque, while cylinder deactivation helps achieve a best-in-class fuel economy rating of 20 mpg city, 31 mpg highway for a combined 24 mpg. A six-speed automatic comes standard.
In a segment where rear-dive is the norm, Acura is charting a risky course, putting power to the front-wheels. While exploiting the better all-weather and fuel economy of the front-drive setup, Acura is also employing what it calls PAWS (Precision All-Wheel Steer) to mitigate some of the dynamic disadvantages.
A rear-wheel steering system, P-AWS is the first to allow for independent steering (toe) angles, reducing understeer, improving overall cornering capability and resulting in better stability under braking.
P-AWS is, however, somewhat rudimentary compared to the level of sophistication Acura will use in a new Sport Hybrid Super Handling All-Wheel Drive system that will arrive later in 2013. Using a V6 hybrid under the hood, rear-wheel torque will come via two independent electric motors, allowing for impressive levels of grip and 370 hp. Acura also claims the SH-AWD model will get 30 mpg city and 30 mpg highway for a combined 30 mpg.
