Despite what appearances and the new trapezoid grille may have you thinking, the improvements made to the 2013 Lexus RX go much further than skin deep. Its 3.5L V6 engines have been revised, offering 270 horsepower, or 245 in the case of the hybrid. This year, an F Sport version has been added with more dynamic style and handling. This vehicle’s cargo space ranges from 1,132 to 2,273 litres.
