The RLX is the flagship sedan for the Acura lineup. Replacing the long-running Acura RL, the RLX is a couple of inches bigger and about $10,000 more expensive than the next closest Acura, the TL sedan. Compared to other luxury sedans the RLX is slightly larger than the BMW 5-Series, Audi A6 or Mercedes-Benz E-Class, but significantly smaller than flagship sedans like the BMW 7-Series, Mercedes-Benz S-Class or Lexus LS. The base RLX is front-wheel-drive with a 310-bhp V6 engine under the hood, but the range will include an advanced all-wheel-drive hybrid powertrain similar to that of the next NSX. A new all-wheel-steering system can independently control the left and right rear wheels for enhanced steering control. Pricing starts at just under $50,000.
