Verdict

The Infiniti FX - or Infiniti QX70 following the brand's renaming of its models in early 2013 - is the largest car in the line-up of upmarket vehicles from Nissan's luxury car brand. It competes against the Porsche Cayenne, BMW X6 and Range Rover Sport but claims to be more driver-focused than all of the alternatives.

Unlike the Cayenne and Range Rover Sport, the FX has no off-road ability. However, it has the presence of a large 4x4, and - Infiniti claims - the agility of a coupe. This is the second-generation FX model, the original having been a success in North America and a few private imports of the earlier model made it to the UK. Now the interior has a less mass-produced feel with expensive looking trim and excellent attention to detail. If petrol really is your thing you'll go for the thirsty 3.7-litre V6 or 5.0-litre V8. The 3.0-litre V6 diesel is more UK-friendly, offering better fuel economy and lower emissions.

Strong performance

Whichever engine you choose in the Infiniti FX, they all offer good performance. Quickest of the bunch is the 5.0-litre V8-powered 50 S that has some 385bhp at its disposal to get the large SUV from 0-62mph in 5.8 seconds, working smoothly through its seven speed automatic gearbox.

Next quickest is the 3.7-litre V6 used on the 37 models that has 315bhp and deals with 0-62mph in 6.8 seconds. It also offers useful overtaking urge and is a little more economical than the V8 petrol.

If you want reasonable economy in the FX you’ll need to choose the 30d model that has a 235bhp V6 turbodiesel. It covers 0-62mph in 8.3 seconds and overtakes with easy strides. The limited edition FX Vettel has a 414bhp version of the 5.0-litre V8 for a 186mph top speed and 0-62mph in 5.6 seconds.

Poor ride and noisy diesel

Despite its size, the FX handles very well and has sharp responses. However, the suspension and very large wheels conspire to give the car a very firm ride, which makes the FX unpleasant to be sat in when driving on rougher roads. Even on smoother tarmac, the FX has an unyielding quality to its ride that leaves you wanting something more supple. The steering of the FX is also quit heavy at low speeds, making parking more of a chore than it should be. To find out more read the full Infiniti FX review that follows.
