The 2009 FX will be available in two different choices: the FX37 and the FX50. As you suspect already one will be powered by a 3.7 liter and the other by a 5.0 liter engine.
The FX37 wil be powered by the same 3.7 liter VQ-series V6 engine engine used in the G37 Coupe and will deliver 300 hp. The FX50 will be powered by a 5.0 liter engine with an output of 390 hp and 369 lbs-ft.

The new VQ37VHR, first used in the G37 Coupe is based on the award-winning VQ engine series, named one of the "Ten Best Engines" by Ward’s Auto World magazine for 13 consecutive years. next to a bigger output, the FX37 will also use the new VVEL system which combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side to help improve performance and response. The VVEL system is also expected to improve emissions and fuel efficiency.
The 2009 FX will have the same dimensions as the current FX. Infiniti will use materials that will reduce weight, this is why the up-coming FX will be faster compared to the current model.
The biggest changes will be made to the front of the car. The exterior will be more sporty and modern.
The exterior highlights will include flowing front fender curves, expressive front fascia with Infiniti’s signature double-arch grille and L-shaped High-Intensity Discharge (HID) bi-xenon headlights with integrated fog lamps. Also the rear will feature large LED taillights – an Infiniti trademark, refined rear bumper and an integrated RearView Monitor camera. The camera will help you to have a 360 degree view of what was around you.
