2011 Infiniti FX Performance
This performance review was created when the car was new. Some links may no longer point to an active page.
The 2011 Infiniti FX is one of the sportier SUVs out there and its powerful engines don't disappoint. However, some critics say that its sporty handling takes a toll on ride comfort.
- "The hairpin turns through mountain passes were perfect for defining the FX's sporty nature. And yes, it does drive like a sports sedan. Yet, I wouldn't go as far as to say it drives like a sports car, which is usually a coupe." -- AutoTrader
- "The FX goes like stink and offers sporty handling along with some cargo capacity." -- New Car Test Drive
- "I comfortably drove it down a rocky track in the Nevada desert, an adventure that wouldn't have been possible in the previous FX without wearing a mouth guard and a kidney belt." -- New York Times
Acceleration and Power
The FX35 comes with a 303 horsepower 3.5-liter V6 engine, while the FX50 upgrades to a 390-hp 5.0-liter V8. Both are paired with a seven-speed automatic transmission. Reviewers find both models provide more than enough power, and even say the V8 might be too powerful. For most buyers, the V6 should suffice -- and it will save you more than $10,000 as compared to the pricey V8 model.
According to the EPA, the rear-wheel-drive FX35 should achieve 16/23 mpg city/highway, while the all-wheel-drive model should net 16/21 mpg. The FX50 comes with standard all-wheel drive and is rated at 14/20 mpg. The FX35's ratings are quite good, with only a few SUVs getting more miles per gallon. These include the Lexus RX 350, RX 450h, and Lincoln MKX.
- "The new rip-roaring Infiniti FX50 is a fine sporty crossover SUV, but with 390 horsepower, it's a bit over the top. For starters, who really needs one of these tall wagons to run 0 to 60 mph in 5.0 seconds, as the FX50 does?" -- Car and Driver
- "FX35's 3.5-liter V6 is spunky from a stop and competent and adequately powerful on the highway." -- Consumer Guide
- "The FX's smooth, sure-shifting seven-speed automatic transmission is the unheralded star in this thrilling automotive production." -- MSN
Handling and Braking
The FX features a front independent double-wishbone suspension, rear independent multi-link suspension, and speed-sensitive power steering. The system gives the FX especially sporty handling for an SUV. The FX50 has an optional $3,000 Sport Package that adds Continuous Damping Control with Auto and Sport modes. However, many reviewers find the ride overly harsh in Sport mode.
- "FX is very nimble and exhibits excellent handling response with minimal body lean. It finds itself at home on even the curviest of roads. Steering is firm, but direct and responsive. Solid, reactive brakes furnish smooth stops." -- Consumer Guide
- "The ride might be a bit too firm for some, even in the Auto setting instead of the more aggressive Sport." -- Road and Track
- "The FX produces impressive grip by any standard. Diving into turns makes it easy to forget all the practicality that an SUV body style represents. The FX claws at corners, with no squealing tires, just a scrubbing sound that seems to say, 'Bring it on.'" -- MSN
