About Infiniti FX45
The Infiniti FX is an SUV for those who enjoy driving. Both the V6-powered FX35 and the V8-powered FX45 give the enthusiast SUVs from Mercedes-Benz, BMW, and Porsche a run for their money, especially your money, because the Infiniti models are less expensive than the German competitors. However, in terms of acceleration and handling, they are no match for the Europeans. Because it is more like a big sport coupe than a truck-based SUV, the FX drives more like a big sport coupe.
Both Infiniti vehicles are thrilling to drive; they are smooth, powerful, and quite stable. Because of their large, powerful brakes and stiff, fully independent springs, they can be driven significantly harder than standard sport utility vehicles. On the highway, they seem much more rooted and confident than standard SUVs. The FX35’s V6 engine is the same as that found in the Nissan 350Z sports vehicle. It’s powerful, providing responsive performance to the FX35. We never found ourselves pining for the more powerful FX45 when driving the FX35.
In fact, both FX models share the same mechanical architecture as the Nissan 350Z and Infiniti G35 coupe. They are not based on any Nissan truck or, as some appear to believe, the similarly sized Nissan Murano SUV. (The Murano’s front-wheel-drive design is shared with the Nissan Maxima and Altima.)
Creating an SUV from a sports car, on the other hand, necessitates some trade-offs. While the BMW X5, Mercedes-Benz M-Class, and Porsche Cayenne all have varied degrees of off-road capability, they are all better suited to tough terrain than the FX. The FX was built largely for on-road performance, with an optional all-wheel drive system particularly for increased handling and performance in the snow. Although it has been strengthened up for SUV duty, its chassis is still not as substantial as that of a real off-road vehicle, which lessens the weight that its strong engines must move.
Infiniti also outfitted the FX with massive (optional) 20-inch wheels and tires, race car-sized brakes, and a taut, handling-tuned suspension. The goal was to make the FX as thrilling to drive as a sports car, which Infiniti accomplished by sacrificing ride comfort, spaciousness, and rock-climbing capabilities. The end result is a car-based crossover SUV with personality and excitement to drive on sports-car roads, but it also has a harsh ride, a tighter cockpit than some of its competitors, and flashy aesthetics. However, for dedicated sports-car aficionados who need to get their winter toys through the snow belt, this could be just the ticket.
The FX was introduced for the 2003 model year. Upgrades were made in 2004. Roof-mounted additional side-curtain airbags are standard equipment for 2005, providing rollover protection for both front- and rear-seat occupants. Optional intelligent cruise control and a Lane Departure Warning system, the first of its kind on a passenger car in the United States, are also new for 2005.
