"The Infiniti Q70 is a quirky choice in this segment but while it's comfortable and spacious, the expensive price tag and high running costs help to make rival models better value."

For those looking to break the norm and move away from class leaders such as the BMW 5-Series and Mercedes E-Class, the Infiniti Q70 executive saloon makes an intriguing alternative. The range consists of a pair of diesel engines, one petrol and a hybrid – all of which boast comprehensive equipment lists, as well as eye-catching looks, decent build quality and performance, and spacious interiors. But although the Q70 is an excellent all-rounder, it can't keep pace with established rivals, particularly in the increasingly important field of running costs.

MPG, running costs & CO2

2.3 / 5

The Infiniti Q70's fuel economy and road tax bills will make your eyes water

Although the introduction of a 3.0-litre diesel engine to the range has improved fuel economy slightly, returns of less than 40mpg and CO2 emissions of 199g/km are still poor, and lag behind class leaders. A 2.2-litre diesel was introduced in September 2014, but fuel economy and emssions figures are yet to be announced.

The petrol's economy figure of 28mpg is truly abysmal. Not only are fuel costs high, so is annual road tax – the oil-burning Infiniti Q70 sits six tax bands above its BMW 5-Series equivalent. Servicing and parts are also pricey. At least the forthcoming hybrid should improve things in this category.

Engines, drive & performance

2.2 / 5

The diesel engines are the pick of the Infiniti Q70 range, while S variants offer sharper driving experience

Of the engines on offer, the 3.0-litre diesel is smooth, refined and delivers plenty of mid-range punch – sprinting from 0-62mph in a rapid 6.9 seconds. The petrol is marginally quicker from 0-62mph, in 6.2 seconds, making for easy overtaking, but it's very costly to run. Both models use a seven-speed automatic gearbox, which can feel ponderous if you up the pace.

Those seeking agile handling would be better served by opting for an S-spec model, which gets a tauter chassis and four-wheel steering system. In bends, the Q70 offers decent grip and body roll is well controlled.

There's also a smaller 2.2-litre diesel and quiet petrol-electric hybrid – but only the former offers truly low running costs.

Interior & comfort

3.2 / 5

The Infiniti Q70 is smooth, quiet and refined

Infiniti Q70 GT models prioritise comfort, and soak up imperfections in the road well. Standard double glazing means wind noise is kept to a minimum, and while the diesel unit is audible at idle, it's not intrusive.

The 20-inch wheels found on top-spec S cars make for jittery progress, but finding a comfortable driving position is easy, with plenty of seat and steering wheel adjustment. Shallow rear windscreen restricts visibility slightly.

Practicality & boot space

3.3 / 5

The Infiniti Q70 gets a spacious cabin that can easily accommodate four adults

There's acres of room in the Infiniti Q70's cabin, both front and rear, for four adults. Legroom is ample, and despite a swooping roofline, it doesn't impact on headroom. However, the intrusive central transmission tunnel means that the middle seat is for small children only.

Petrol models boast a useful 450-litre boot, while diesels get a more generous 500-litre load area. Yet both are outclassed by the BMW 5-Series and Mercedes E-Class.

Reliability & safety

4 / 5

Top-drawer reliability and customer service, but the Infiniti Q70 can't compete with rivals for quality

Infiniti has an impressive reliability record and offers first-class customer service, so any problems should be dealt with smoothly and efficiently. The Infiniti Q70 feels well built and the quality of materials used is superb, although it can't quite match premium German rivals.

Price, value for money & options

2.2 / 5

The Infiniti Q70 is generously equipped, but costly to buy

Even the entry-level Infiniti Q70 comes loaded with equipment, including keyless entry, reversing camera and dual-zone climate control. Range-topping S-spec cars add sports suspension, gearshift paddles and four-wheel steering.

However, the Q70 is expensive to buy and resale values aren't expected to compete with rivals. Its exclusivity on the UK market is a plus point, though.
