Infiniti FX45 Concept Vehicle Redefines ‘Crossover' SUV Category With Emphasis on On-Road Performance

Infiniti has a tradition of bringing new dimensions to existing model segments: the original Q45 brought a new level of performance to the large luxury car market, G20 added a taste of sport and luxury to small cars, and QX4 brought a new dimension of luxury to the luxury SUV market, even before that segment truly existed.

Enter the FX45 Concept vehicle, a new type of Infiniti concept created to take on the rapidly expanding 'Crossover Luxury' SUV market. The FX45 Concept vehicle features V8 power, all-wheel drive, exceptional performance and distinct interior and exterior appointments.

FX45 Style, Inside and Out

The low-slung FX45 Concept vehicle combines the best sport utility vehicle qualities, including optimized space utilization, four full-size doors for passenger entry and a large rear hatch for cargo with sports car styling — a low slung, wide stance and huge wheels and tires.

Inside the leather-appointed passenger compartment, personalized zones call out specific areas, unlike a traditional SUV, which is usually wide open and formless. The driver's zone, maximized for the driver's enjoyment, features integrated tilt steering and instruments, as well as a 9.5-inch LCD monitor that provides functions for the advanced navigation system, HVAC controls, audio controls, Infiniti Communicator, Internet and E-mail access.

The front passenger zone has its own climate controls for maximum comfort. The rear zone, for rear seat passengers, features a DVD player, video game system and a rear water bottle cooler. The entire interior is covered with Alcantara fabric and solid aluminum parts, giving the FX45 passenger an exciting contrast of warm and cool design cues.

FX45 Performance

'FX45 Concept vehicle performance target is far above that of the current crop of SUVs,' said Orbe. 'Instead, we targeted large sports luxury cars, such as the BMW 7-series, Lexus GS430 and our own 2002 Q45.

A specially tuned 32-valve 4.5-liter V8 with more than 300 horsepower and 300 ft-lbs of torque powers the FX45. Backing this powerful engine is a 5-speed automatic transmission with manual mode. Distributing power to the ground is an All-Modeâ driveline, adapted from the system found in the Nissan Skyline GT-R supercar, for superior performance in dry and adverse weather conditions.

The 4-wheel independent suspension is tuned for on-road handling prowess. Assisting vehicular control is the Vehicular Control System, which controls brake pressure and engine torque in over- and understeer situations. 'With its high performance sports orientation, we feel that an FX45 driver will not participate in serious off-roading,' said Orbe. 'Instead, we've given it stability and exceptional performance in light traction situations such as rain, snow or gravel.'

Braking is provided by large 4-wheel discs with Anti-lock. Electronic Brake Distribution, which distributes braking forces depending on vehicle load and the Brake Assist System, which aids the driver in panic braking situations, aid braking stability in the FX45 Concept.

20-inch wheels with 285/50R20 tires complete the FX45 Concept vehicle's suspension and give it an aggressive, broad-shouldered look.
