Infiniti Q60 coupe (2013-2016)

Starting from around £36,000 for the entry-level model, the Infiniti Q60 (previously the Infiniti G37) is a stylish and genuinely unique-looking coupe that stands out from the crowd. Powered by a modified version of the 3.7-litre V6 petrol engine from the Nissan 370Z, the sporty coupe isn't short on performance, either. Inside, it's luxurious, comfortable and well equipped. But with its high running costs, lack of engine variety and shortage of both rear-seat and boot space, the Q60 lacks the all-round competence of rivals such as the BMW 4 Series and Mercedes E-Class coupe.

Running a Q60 isn't cheap. Currently it's only available with a Nissan's thirsty 3.7-litre V6 petrol engine, which returns 27mpg fuel economy and emits 246g/km of CO2, so road tax is £490 a year.

Buying a Q60 coupe is made easy by the fact that there's only one engine in the line-up. The 3.7-litre V6 is borrowed from the Nissan 370Z sports car, but it's more refined here to suit the Infiniti's more relaxed nature. There's still impressive performance on offer, though, with a 0-62mph time of 5.8 seconds.

A six-speed manual gearbox comes as standard, but there's also an excellent seven-speed automatic available as an option. When the road gets twisty, the Infiniti continues to perform well, with responsive steering and lots of grip. Some drivers may prefer a little more feedback through the wheel, though.

The Q60 is refined, luxurious and comes with an impressive amount of standard equipment – even in the most basic GT trim. Cabin noise is almost non-existent, too, due to the Q60's excellent sound insulation. The back seats are cramped and awkward for adults, but up front there's plenty of leg and headroom and the seats are comfortable, with an excellent driving position.

Due to a steeply sloping roofline, space in the back of the Q60 is minimal. This results in a '2+2' seating arrangement, where the rear 'passenger' space is better used as additional luggage storage. Compared to its rivals, the Q60's boot is very small, too: at only 275 litres, it's over 150 litres smaller than what you get in both the BMW 4 Series and Mercedes E-Class coupe.

Despite using a large amount of Nissan parts, the Infiniti Q60 feels remarkably well built, although it doesn't feel as luxurious and prestigious as its premium brand image suggests. But Infiniti as a company has a very strong record for reliability and the Q60 is no different.

Starting from £36,000 for the entry-level GT model, the Infiniti is not a cheap proposition compared to similarly priced, better performing and more competent European rivals. Despite its relatively exclusive status and rarity, the Q60 also has poor residual values.
