Infiniti Q50 Eau Rouge performance concept storms 2014 Detroit Show

The Infiniti Q50 has been designed to take on the BMW 3 Series – but Infiniti is trying to attract a more youthful set of customers and efficient diesel and hybrid saloons aren’t exactly going to gain any favour with the young crowd.

This thing has been designed to take on the mighty BMW M3 and could well have the weaponry to succeed.

Clay Dean, director of GM North America, said the Cadillac Urban Luxury Concept stood comparison with Europe's finest city cars. At just under 4 metres long and 1.7 metres wide, he has a point.

VW Golf R 400 could get more than 400PS – which makes a bit of a nonsense of its name

The VW Golf R 400 (pictured) may not actually be an R 400 The Beijing Motor Show last month saw the debut of the VW Golf R 400, an extreme take on the VW Golf R with a full 400 PS (395bhp) at its disposal. When Volkswagen revealed the R 400 as a concept we did note that it looked more production-ready than concept, and it took VW less than a week to confirm that the Golf R 400 was indeed heading for production. Now, just to muddy the waters a bit (or raise expectations), VW’s R&D chief Heinz-Jakob Neusser has said that when the Golf R 400 does arrive it could well be with more than 400PS.
