Two models are available: Infiniti FX35 ($34,200) is powered by the 3.5-liter V6 from the Nissan 350Z. FX45 ($44,225) gets the 4.5-liter V8 from the Q45 luxury sedan.
Both come with a five-speed automatic transmission, dual-zone climate control, power front seats, split folding and reclining rear seats, tilt/telescope steering wheel, traction control, stability control, brake assist, and high-intensity discharge headlights.
FX45 gets a firmer suspension, 20-inch wheels, leather heated seats and trim, power tilt/telescope steering wheel, memory for seat, mirrors, and steering wheel, auto up/down windows. FX35 offers those items in its a Premium Package ($2,600), which also includes a sunroof, a more-powerful stereo with controls on the steering wheel, automatic headlights, and a garage door transmitter. You can add the last four items to the FX45 in a Premium Package ($2,100).
Both models offer a Technology Package that includes all of the options in the Premium Packages, plus a navigation system, a remote sensing door key, traffic-sensing cruise control, a DVD system, a rear facing camera to assist backing up, and a tire pressure monitor. The Technology Package for the FX35 also adds the 20-inch wheels and the stiffer suspension, and costs $9,400 on top of the FX35's base price; the package adds $7,600 to the FX45's base price. Roof rails are available for $300 on cars with the Premium Package and satellite radio is $400.
Only a third of Infiniti SUV buyers are expected to buy the FX45. A lower-priced V6-powered FX35 starts at $34,200 in rear-drive-only form, though only about 14 percent of buyers are not expected to get the $1500 all-wheel-drive system that's available on the FX35 and standard on the FX45.
