An excellent mid-size Acura RDX. This Acura RDX has refined handling, a smooth V6 engine, and a premium cabin with ample passenger space for fit up to 5 riders in the car. The RDX has a 3.5-liter V6 engine that produces 273 horsepower. It’s paired with a six-speed automatic transmission. The smooth V6 provides zippy acceleration and returns good fuel economy (up to 20 mpg in the city and 28 mpg on the highway). The RDX’s precise steering gives it a sporty feel, but the ride is comfortable. The RDX can tow 1,500 pounds when properly equipped.
