The standard RLX has a V6 engine and Acura's P-AWS system -- that stands for Precision All-Wheel Steer -- and a roster of amenities. They include leather interior, navigation with real-time traffic, tri-zone climate control, 12-way-power front seats with heating, moonroof, and 14-speaker audio system with Bluetooth, USB input and HD Radio. The AcuraWatch safety and driver-assist system bundles forward-collision warning with automatic emergency braking, adaptive cruise control with low-speed follow, blind-spot monitoring, lane-departure warning and lane-keep assist. Optional Equipment The way to get more amenities and features in a 2018 RLX is by stepping up to the Sport Hybrid model. In addition to more power and its sophisticated powertrain, it adds that fine Krell audio system (see Favorite Features), ventilated front seats, heated rear seats and heated steering wheel, surround-view camera, parking sensors, head-up display and an upgraded climate system with air-quality sensor. Other nice touches include a power rear sunshade, windshield de-icer and auto-dimming side mirrors.
