The FX50 comes with bigger, showier wheels, but that's about the only difference between the two models. 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. For 2011, a power rear liftgate has been made a standard feature across the FX line.
The 2011 Infiniti FX models are true luxury vehicles, meaning that whether you go for the 2010 Infiniti FX35 or FX50, either version comes equipped with pretty much everything you'd expect for comfort. And if you want some cutting edge tech features, that's a little extra.
