Infiniti Q50 review

You might not be familiar with Infiniti because it's newish to Britain and has few dealers. It's Nissan's posh brand - the same relationship as Lexus has to Toyota. It's also got its name on the side of the all-conquering Red Bull F1 team, if that makes you take it more seriously.

The Q50 is a mid-size rear-drive saloon, and the mainstream version has just the specification to rake on the established and obvious rivals including the BMW 320d and Mercedes C220. It uses a four-cylinder diesel (borrowed in fact from the Mercedes). But the top-end version is more of an oddball, a ‘performance hybrid' with a V6 petrol plus electric assistance.
