The Acura RLX, a full-size luxury sedan, has undergone a few cosmetic changes this year and now features the same hybrid technology found in the NSX sports car. The RLX's primary engine remains the 3.5L V6, which generates 310 horsepower and 273 lb·ft of torque. It is paired with three electric motors, including two located in the rear wheels, making the RLX's all-wheel-drive system one of the most sophisticated out there. In total, we're talking 377 horsepower.
