From £45,001
A worthy competitor to a diesel Cayenne, X6 or Range Rover Sport

Our Verdict

Infiniti FX
Infiniti describes the FX as “the crossover without compromises”

The Infiniti FX is an interesting alternative to the norm, but lacks space and comfort to compete in this class

    Infiniti FX30d S Premium

    You'll have to really like FX30d's toys and looks to choose this over the Cayenne

What is it?

This is Infiniti’s much-needed diesel-powered FX SUV, which will dramatically increase the brand’s chances in a European market segment that is 80 per cent oil burning. Of the three thousand or so Infinitis sold in the EU so far, 55 per cent have been FX models.

The FX30d is powered by a version of the Renault-Nissan V6 turbodiesel engine, albeit much modified. Infiniti’s involvement in the V9X project from inception means it gets changes to the block, crankshaft, turbocharger, heads, sump and intercooler system.

The block is made from Compacted Graphite Iron, the heads are aluminium and the variable nozzle turbocharger sits in the ‘V’ of the engine. The unit develops 235bhp and 406lb ft of torque, which peaks at just 1750rpm.

The active engine mounts work in two stages; soft at start-up to damp out vibration and then stiffer when the FX is traveling at higher speed. The latter mode also improves the handling by more securely locating the engine.

The engine drives a 7-speed autobox, which, in turn, drives the car’s ATTESA all-wheel drive transmission. Fundamentally, the FX is a rear-drive car with a front-mid-mounted engine. That means under normal conditions, 100 per cent of torque goes to the rear wheels, up to 50 per cent to front on slippery surfaces.

What’s it like?

In a word, honed. The new engine is as refined as the competition, certainly in terms of the absolutely minimal vibration and harshness that reaches the cabin. There’s an argument that the engine noise itself is a little more noticeable than the equivalent BMW or Mercedes V6 diesel, but it’s not unpleasant.

It’s quick too, with plenty of pace on the motorway. On winding roads the FX’s balanced weight distribution and direct steering mean this big machine can be chucked around with some abandon and impressive accuracy. It even rides well on the 20in wheels.

I spent most of the test drive in the slightly less aggressively tuned GT model, but a short run in the ‘S’ model (which gets Continuous Damping Control and rear-wheel steering) proved again that this version of the FX is unsung hero. The superb body control and rear-steer lifts this wieldy car onto another level.

Should I buy one?

If you are contemplating a diesel Cayenne, X6 or Range Rover Sport… then, yes. The FX is not huge inside, but it is very well made and the new engine – which returned 28mpg on a hard drive around Barcelona – is up there with the best. It’s well equipped, too. With the specifications matched, it can be significantly cheaper than the Porsche or BMW.

hhhmmm it needs to be. it's really very ugly. i would even go as far as to say that it makes the x6 look nice.

Approx. 40g CO2/km more than the X5/X6/Cayenne/Touareg/ML/Q7 3 litre diesels; up to a second slower, and up to £10k more, for inferior performance, space, fuel efficiency and higher purchase/VED/BIK taxes. Yeah Hilton, real competitive. What a pile of overpriced Datsun/Renault tat.

I really can't get past how ugly it is, and the inside looks pretty dire too..

[/quote] Correction, if you're contemplating one of the above please place your head in the nearest gas oven. This does actually look better in real life than the pictures do justice, though I'm certainly not a fan. On the otherhand the interior is actually very, very smart, again it doesn't seem to photograph well. I like the fact that it's RWD until slip is detected.

The x6 is much nicer then this hideous creation and the interior looks miles nicer then the one in this Nissan, why would anyone but this over the x6 ? and dont give me that line I want to be different !

Based entirely upon those objective measures, it may not be as competitive, but the very fact that we are on this website, seeking subjective opinions on this car, means there is far more to being competitve in the automobile market than comparisons of performance, space and fuel efficiency.

Exactly. And the previous poster might want to go to the thread 'What is the point of the X6'....

Thank you! I was about to point out this unforgivable heresy myself...

I do have a few problems with this, though.

First, the cabin looks awful - steering wheel looks like it's off a Micra.

Second, the engine. Now, let's lay aside my dislike for V6s - but this seems, to me, to be not all that economical, not brilliantly powerful either, and heavy with it. Why are they using this and not the more economical, more refined, more powerful and (GET THIS) ALUMINIUM-block Merc 320/350 CDI unit, as they've got that powertrain agreement with Merc? Strikes me as odd...

Mine's an X5 xdrive40d, thanks.

Not really. Mine's a Range Rover 4.4 TDV8, but shorn of the bling they've inflicted on the L322 over the last couple of years.
