Although sport suspension tuning gives the RX 350 F Sport better handling, the ride quality loses its luxury feel and the vehicle struggles for a purpose.
Lexus' RX model has been a stalwart in the lineup, a five-seater SUV offering luxury amenities. For 2013, the vehicle experiences little change from previous model years, with no change in engine or basic features.
F Sport gives the RX 350 more rigid suspension tuning, which results in better handling but also makes the ride rougher. An all-wheel-drive system includes a differential lock mechanism, useful for particularly slippery surfaces.
As an odd choice for the F Sport trim, Lexus throws in an eight-speed automatic transmission, giving the RX 350 two more gears than come with other trims. Sporting performance benefits little from the different transmission.
