Infiniti EX (2009 – 2013): At A Glance

The Infiniti EX isn't merely a new car. It's one of a range of cars, previously unheard of in the UK, but very well known on the other side of the pond as Nissan's equivalent of Lexus -  a high quality premium make that offers something different to the usual German makes.

It was initially available only as a petrol and used a detuned version of the 3.7-litre V6 engine that can also be found in the Nissan 370Z. With 320PS it's very rapid and sounds great too, but economy is a shortcoming as it only returns 25.0mpg. What the EX desperately needed was a diesel engine. Luckily it didn't have to wait long and in July 2010 Infiniti introduced its first ever diesel - a 3.0-litre V6.

This means the EX now makes much more sense and its no surprise that Infiniti expects the majority of buyers to go for the diesel model. It's refined but punchy and actually feels quicker than the petrol in everyday driving thanks to its enormous torque reserves of 550Nm. But the best bit is average fuel consumption of 33.2mpg, making it far more affordable in terms if running costs.

In terms of categorising the EX, that's not particularly straightforward. It's more of a 'crossover' than a 4x4 and although it does have all-wheel drive a standard, this is no off-roader. It's smaller than the BMW X6 and isn't as tall as an Audi Q5

Interior quality is an area where choosing a premium make really makes a difference. The likes of Audi and BMW manage to create sophisticated and modern interiors that are not only stylish but also user-friendly. It's not always an easy feat to manage but the EX is pretty close. The quality of the finish and the high grade of the materials used is immediately obvious as soon as you get behind the wheel with leather trim and high gloss finishes.

There are quite a few switches and controls which may be familiar to you if you've ever driven a modern Nissan before, but they don't detract from the high-end feel. The design isn't especially adventurous but everything is easy to find and straightforward to use, it's just slightly lacking in the cohesion and sharpness of the German makes. But comfort levels are superb and the seats are some of the best around for plushness, although a bit more side support wouldn't go amiss.

There's decent rear passenger room too, although with the front seats pushed all the way back, rear legroom is pretty restricted. Head room is generous and the boot is usefully large too. But where the EX really has the edge over its rivals is standard equipment. It's absolutely loaded with kit, most of which would be (expensive) optional extras on other premium makes.

What's the Infiniti EX (2009 – 2013) like to drive?

All Infiniti models share the same basic chassis and it's a platform that was designed for sports cars. As a result the EX handles very well with impressive body control and great cornering ability - it certainly doesn't feel like a 4x4 usually does. The steering is a touch light and has a slightly artificial feel, but it's still very precise so tackling sweeping bends is enjoyable and the car deals incredibly well with quick changes of direction thanks to impressive agility.

The all-wheel drive system means there's excellent traction too, especially noticeable when pulling away from junctions in the wet or where there's loose gravel. The EX manages that rare feat of being flat in corners thanks to a firm suspension set-up, but still forgiving over bumpy and uneven roads. It's very comfortable and makes for a great long distance cruiser with very little wind or road noise at higher speeds and a cossetting feel in the cabin.

Originally just one engine was available, a 3.7-litre V6 petrol with 320PS that's actually a detuned version of the unit that powers the Nissan 370Z. It's very refined and silky smooth at a sedate pace but has a great turn of pace when you want it to. Accelerating flat out from 0-62mph takes just 6.4 seconds and the V6 sounds great pulling from low down.

It can feel quite strained at higher revs though, but the advanced seven-speed automatic gearbox that comes as standard means you can make the most of the power as it delivers incredibly quick yet smooth shifts. One disappointment is that there aren't paddles on the steering wheel allowing you to change gear yourself plus the the American style foot operated manual parking brake is very effective, but a bit outdated these days.

Most people choose the diesel-powered EX which was introduced in July 2010 and is a very welcome addition to the range. This is Infiniti's first ever diesel engine and the good news is that it's a real gem. It's hushed on start-up but you're always aware of that underlying V6 engine note while the exhaust system has been specifically tuned for the diesel to deliver a suitable sporty sound, especially when accelerating. On paper the 235PS covers the 0-62mph spring in a respectable 7.9 seconds - that's considerably slower than an Audi Q5 3.0 TDI - but its 550Nm of torque means that in everyday driving it feels quick enough.

In-gear acceleration is punchy and it really shows its strength from 50-70mph which is a much better measure of real world acceleration. You don't need to force the gearbox to kickdown either as it's responsive and pulls very well from a high gear anyway, although having seven-speed does seem a little pointless given the torque on offer. It's good on the motorway where it settles down to around 1900rpm at 70mph so you can barely hear it as you cruise along.

I like the looks of the Audi A5 sportback. I see the BMW 5 Series GT as an alternative, but it lacks style. The Porsche Panamera is too expensive. I need the hatchback (dog) and want 4 doors with style for long distance cruising. Are there any other cars I should be considering?
Infiniti EX37 or EX30d.
