Proudly Serving Fort Worth, TX

With a stunning new look, the 2018 Acura RLX and its Sport Hybrid edition are staking a bigger claim to the luxury sedan market. These spacious rides offer a long list of features, including cutting-edge crash avoidance standards.


The RLX has serious power for your driving pleasure. Rated at 310 horsepower and 272 lb.-ft. of torque, it won’t disappoint. The new model benefits from a ten-speed automatic transmission which gives it a broad torque arc. Fuel economy is 20 mpg city and 29 mpg highway. At 23 mpg combined, U.S. News and World Report calls it one of the more economical members of its class. Precision All-Wheel Steering puts the driver firmly in control.

If you step up to the RLX Sport Hybrid, you’ll save even more at the gas pump. By combining the same 3.5-liter V6 with three electric motors, fuel economy rises to 28 mpg city/29 mpg highway. Using the motors, the RLX Sport Hybrid can switch between front- and rear-wheel drive, balancing torque to achieve the best traction. This Super-Handling All-Wheel Drive system works rain or shine, improving daily travel on dry days as well as snowy ones. Fuel economy is 28 mpg city and 29 mpg highway. Best of all, power outlay is 377 horsepower and 341 lb.-ft. of torque. A seven-speed dual-clutch automatic controls the action. RLX sedans earned all five stars from the federal crash testers.


With either RLX, a diamond pentagon grille is matched to a sculpted hood. The sleek look is accentuated by jewel-eye headlights. The new look reflects Acura’s Precision Crafted Performance DNA design. Of the seven exterior colors, six are new. Consumer Reports calls the RLX impeccably finished, noting the plush, inviting and spacious interior. Wherever you may touch on the dash or doors, you’ll find padded or wood-covered accents. The comfortable, well-appointed cabin has soft perforated leather upholstery. New for 2018, there’s a rich Espresso leather and a high-contrast stitched Milano leather on the menu. The power-adjusting front seats can also be power-heated. The second row benefits from the tri-zone automatic climate controls. Sport Hybrid editions pamper you even more with a heated steering wheel, ventilated front seats, and heated back seats.


The dual-screen infotainment center lets you put information where you want it. The upper screen can be used for navigation. The lower touchscreen controls your audio.
AcuraLink includes Pandora and other important apps. The hands-free phone system is complemented by SMS Hands-free Text Messaging. Exterior safety aids include rain-sensitive wipers and heated side mirrors. While many luxury makers hold back on their crash avoidance systems, AcuraWatch comes standard on every RLX. Safety technologies include a lane departure warning which may trigger a lane keeping assist and a forward collision warning that may utilize an automatic braking function. Unique to the Acura family, a standard road departure system uses throttle reduction and steering cues to keep the RLX or RLX Sport Hybrid on the road. Adaptive Cruise Control, which already had Low Speed Follow, now boasts special Traffic Jam Assist. The rearview camera offers multiple views for better reverse maneuvers. The Sport Hybrid adds front/rear parking sensors and a surround camera system for a 360-degree view. It has a head-up display to keep you informed about speed and other vital data.
