Between the FX35 and the FX50, there's very little feature difference at a standard-feature level; but they're both fully kitted-out as luxury vehicles.
The FX50 comes with bigger, showier wheels, but with the new Limited Edition, you can get 21-inch graphite-finish wheels, dark-tinted headlamps, adaptive front lighting, and other extras on the FX35 AWD. Both models come with a power rear liftgate.
Options are limited to big-ticket tech features like a lane-departure warning system, an adaptive suspension, adaptive bi-xenon headlamps, and a navigation system with an especially good display and interface. The navigation system comes with a 9.3-gigabyte music-storage feature, and Bluetooth is well-integrated.
