Used 2018 Acura RLX Sedan Trims Comparison

The base RLX P-AWS is powered by a 3.5-liter V6 engine making 310 horsepower and 272 pound-feet of torque. It sends power to the front wheels via a new 10-speed automatic transmission.

Standard equipment on the P-AWS trim includes 19-inch alloy wheels, LED headlights and taillights, a power sunroof, automatic windshield wipers, a rearview camera, and keyless entry with push-button start. Inside you'll find three-zone automatic climate control, heated and power-adjustable front seats, leather upholstery, a power-adjustable steering wheel, a dual-screen infotainment system, navigation, Bluetooth, and a 14-speaker sound system with a CD player, HD and satellite radio, a USB-iPod interface, smartphone app integration (Pandora and Aha internet radio integration), and an auxiliary audio jack.

Both the P-AWS and Sport Hybrid come with a full suite of active safety features and driver aids, including adaptive cruise control, lane keeping assist, blind-spot monitoring and rear cross-traffic alert, and forward collision warning with automatic emergency braking.

The Sport Hybrid also adds LED foglights, auto-dimming and power-folding side mirrors, front and rear parking sensors, remote start, and a surround-view camera system. Inside, the Sport Hybrid gets ventilated front seats, heated rear seats, a heated steering wheel, a power rear sunshade and manual rear-door sunshades, a head-up display, and a premium 14-speaker stereo system.

Obviously, the biggest upgrade is the hybrid drivetrain. The V6 motor drives the front wheels through a seven-speed, dual-clutch automatic transmission with a built-in electric motor, and each rear wheel has an independent electric motor. Total system power is 377 horsepower and 341 pound-feet of torque.
