The Infiniti FX was renamed the QX70 recently, following the manufacturer's decision to name all its saloons, coupes and convertibles with the prefix of "Q" and all of its crossovers and SUV models with "QX". A crossover indeed, the QX70 is a performance-oriented car, which we'd place somewhere in between the status of SUV and coupe. It's got a range of powerful engines to back it up, but be careful; the powerful V6 and V8 petrol units will mean running costs soar. The Infiniti QX70 provides stiff competition for the likes of the BMW X6, and while it's not the most practical of SUVs, it handles well and masters corners with ease. It comes in three main specifications - entry-level GT, mid-spec S and top-of-the-range S Premium.

Our choice: 5.0 V8 QX70 S Premium



The Infiniti QX70 has brash, muscular styling and a bold chrome grille, too. It's most easily described as a crossover between an SUV and a coupe. There are three main specifications - entry-level GT, mid-range S and S Premium. All models have at least 20-inch alloy wheels, and 21-inch alloy wheels are available as an option, too. The interior is optimised with 11 speakers, including two subwoofers. Plus, the interior is packed with gadgets and quality materials, but there's a few re-used switches and dials from Nissan cars that look a little out of place. To finish things off, it's also got roof rails.



The Infiniti QX70 is tailored around performance, and all models handle well through the corners. In the engine line-up there's 3.7-litre V6 and 5.0-litre V8 petrol engines, which can manage 0-62mph in 6.8 and 5.8 seconds respectively. A 3.0-litre diesel was recently added to the range too, but it's slower than both petrol models, and noisier. It does manage 31mpg, though, which is significantly more than the petrol versions. All models come with an effective seven-speed automatic gearbox, which changes through gears smoothly. Those wanting to take control themselves can do so by utilising the paddles mounted behind the steering wheel. 



The Infiniti QX70 was awarded the full five stars in the Euro NCAP crash safety tests, thanks to a generous number of airbags and a range of hi-tech gadgets. Intelligent Brake will help bring the car to a halt without the driver's intervention, while lane keep assistant will brake the inside wheels to prevent the car from straying out of its lane. While Lexus is Toyota's upmarket brand, it can definitely be said that Infiniti is the luxury arm of Nissan. All engines, then, have been tried and tested across the Nissan range, so should prove reliable. Interior build quality is great, and there have been no major faults or recalls reported. 



As mentioned before, the Infinti QX70's profile is somewhere between the status of SUV and coupe. The compromise for this styling, unfortunately, is practicality. There's 410 litres of boot space on offer with the Infiniti QX70, but this is 100 litres less than you'll find in the BMW X6 or the Porsche Cayenne. You can, however, fold the spilt-fold rear seats flat to create a much more impressive 1,305 litres of boot space. The interior is spacious enough for four adults, and while legroom is fine, headroom is hindered by the roofline. The back seats do recline for extra comfort, though, plus there're a range of cameras fitted to the front, back and sides of the QX70 which should make parking no task at all.

Running Costs


This isn't a strong point for the Infiniti QX70. Its big dimensions and heavy weight don't help things, and nor do the thirsty engines. Both petrol engines manage just over 20mpg which means that, on an average day, you're likely to achieve something along the lines of 12/13mpg. The least efficient, unsurprisingly, is the top-of-the-range S Premium model, which emits a whopping 307g/km of CO2. That means both petrol models will cost nearly £1,000 for their first year of road tax due to high emissions. The diesel is only a bit better; it manages 32.8mpg and emits 225g/km of CO2. Overall, the Infiniti QX70 will see you spending a lot of time at your local petrol station, which is probably why you hardly see any on the road.
