The 2020 Acura RLX sits at the top of the Acura sedan hierarchy, as the biggest car in their lineup. The RLX is powered by a 3.5L direct-injected V6 that makes 310 horsepower and 272 lb-feet of torque, which is mated to a 6-speed automatic transmission with Sequential SportShift paddle shifters. With a curb weight of 4,000 pounds, the RLX isn't light, but the powertrain works well enough to propel the car to 60 mph in less than seven seconds. The RLX Sport Hybrid makes an extra 66 horsepower over the conventional RLX thanks to a 3-motor system and lithium ion battery combination. The RLX features uni-body construction and rides on independent double wishbone suspension with lower control arms up front and an independent multi-link with coil springs and a stabilizer bar in the rear. Acura's Agile Handling Assist System provides active braking of individual wheels to assist in cornering, while the crown jewel of the RLX's dynamic handling is Precision All-Wheel Steer (P-AWS). The system enables the rear wheels to adjust toe angles independently of each other, while working in conjunction with Agile Handling Assist and Vehicle Stability Assist. Four-wheel disc brakes provide stopping power, while 19-inch alloy wheels hold road-hugging high-performance all-season tires. Up front, "Jewel Eye" LED headlights provide what Acura claims to be a whiter, brighter beam than either HID or halogen lamps. Standard equipment in the RLX with Technology Package includes leather seating, front 8-way power seats, navigation, and a premium 14-speaker audio system and Bluetooth hands-free connectivity. AcuraWatch is also included, which features a multi-view rear camera, Forward Collision Warning system, Lane Departure Warning, Road Departure Mitigation, Blind Spot Monitoring and more. The RLX with Advance Package adds 450-watt 14-speaker Krell sound system, surround-view camera, remote start, power sunshades, heated steering wheel, heated and ventilated front seats and heated outboard rear seats.
