History of Infiniti FX

Infiniti FX First Generation (2002 - 2007)

The FX model replaced the previous QX4 model and was released to mimic the sensation of driving a sports vehicle.
It wasn't easy to attain such remarkable agility and power as an SUV. Hence Infiniti had to make some concessions.
The FX was an SUV with no off-road capability, so the frame would be lightweight. Infiniti built the FX on Nissan's 350Z platform. A thicker structural frame bore the increased weight of the greater body.
The FX35 and FX45 were the two models offered for the 2002 model year.

  • FX35 - 3.5L V6 engine (same engine as the 350Z)
  • FX45 - 4.5L V8 engine (borrowed from the Q45 luxury sedan)

Infiniti FX Second Generation (2008 - 2013)

The second generation of the FX model debuted at the 2008 Geneva Motor Show on March 4 and went on the market in June as the 2009 Infiniti FX. The company renamed the V8 model from FX35 to FX50 to honor its newly built 5-liter engine, the VK50VE, while the V6 model retained the name FX35 due to its use of the VQ35HR V6. Infiniti included Fuel-efficient engines and 7-speed automatic transmissions in the FX's 2008 model year. The company offered diesel engines for the European market for the first time. Europeans favored the diesel version of the FX over the gasoline-powered model, which was not an issue for American buyers.

Infiniti FX37 (Europe)

The FX37, with a VQ37VHR engine, debuted at the 2008 Paris Motor Show and went on the market in Europe in October 2008.

Infiniti FX30d turbo diesel (Europe)

At the end of 2010, a new 3.0L V6 turbodiesel V9X engine was released for the European FX30d. Renault-Nissan Alliance's engine will also power M and EX variants. According to Infiniti's concept, this engine delivers high amounts of polished performance and is the first diesel in the company's history. After considering an 8-cylinder option, the decision was to go with a V6 diesel engine, which provides an excellent mix between power and elegance.


Infiniti sold the 2012 Infiniti FX35 with an MSRP of $43,700 ($54,001 in 2022) for the Base RWD model. The company also offered different trim levels and prices for the 2012 model:

  • Base RWD - $43,700 ($54,001 in 2022)
  • Base AWD - $45,150 ($55,793 in 2022)
  • Limited Edition AWD - $52,000 ($79,404 in 2022)


The Infiniti FX35 engine delivers 303 hp (226 kW) at 6,800 rpm and 262 lb-ft (355 Nm) at 4,800 rpm of torque. The Infiniti FX35 accelerates from 0 to 60 mph (97 kph) in 6.5 seconds with a top speed of 138 mph (222 kph) and a curb weight of 4,167 lbs (1,890 kg). Infiniti sold the FX model as all-wheel-drive (AWD) and rear-wheel-drive (RWD) models. The company also used different engines for this model:

  • 3.0L turbo diesel V9X Engine V6
  • 3.5L VQ35HR V6
  • 3.7L VQ37VHR V6
  • 5.0L VK50VE V8
