The 2018 Acura RLX Sedan makes for an excellent contender in the midsize sedan class. With a single trim on offer, the Acura RLX has a base MSRP of $54,900, competing directly with the Audi A6 Sedan, the BMW 5 Series Sedan, and the Mercedes-Benz E-Class Sedan. Only a 3.5L V6 engine is offered, mated to a 10-speed automatic transmission. Together, they produce 310 horsepower and 272 lb-ft of torque. Accelerating from 0-60 in 4.9 seconds, the RLX maintains a combined fuel economy of 23 MPG. Acura offers the RLX in 7 stunning colors, with the Fathom Blue Pearl being a particular favorite of ours.
