Acura's full-size sedan offers very good quality for price. Even the less posh versions come with a glut of luxury equipment. To get the RLX moving, Acura has entrusted a drivetrain that's very similar to the one in the NSX supercar. In front, there’s a 3.5-litre 310-horsepower V6 that’s assisted, on the SH-AWD version, by electric motors that take charge of the rear wheels, for a combined total of 377 horsepower.
