MG 3 arrives in the UK next month – price from £8399

All the UK models of the new MG 3 (pictured) will cost under £10k MG revealed the UK MG 3 back in June as their design centre in Birmingham, and it’s not a terrible looking thing – at least from some angle. But whether the relatively low tech and the implication that this is the rebirth of MG Motors will be enough to persuade UK buyers in remains in doubt. What will help is a relatively modest entry point, and the MG3 is starting at £8,399 when it goes on sale in the UK in September.

Why the BMW M4 is better than the M3 V8 (2013)

It’s no exaggeration to say that the turbocharged engine in the upcoming BMW M3 (saloon) and M4 (coupe) models is one of the most important engines ever produced by BMW’s M Division. No, it’s not the first turbo lump the performance off-shoot has built – you'll probably know we’ve already had the X5/X6M mutants plus the brilliant 1M and M5 and M6 – but it is the first turbo ever to slot in a production M3, the car that personifies BMW’s iconic performance sub brand, which itself has always been defined by high-revving, naturally aspirated engines. All of this explains why M’s engineers have cut their teeth on other engines first before plucking up the courage to develop the M3/M4 turbo while turning their backs on the outgoing E92 M3’s exceptional V8.

GM gets behind Vauxhall & Opel by dropping Chevrolet in Europe

Cars like the Chevrolet Trax (pictured) will disappear from the UK in 2015 GM has seemed to be fighting a battle with itself in the UK and Europe by marketing a broadly similar range of cars under the Vauxhall and Opel badges in the UK and Opel and Chevrolet in Europe. But unlike the VW Group, which manages to offer very similar cars from VW, SEAT and Skoda and create a different customer base, GM seems to have failed to make the marketplace work with Opel and Vauxhall competing with Chevrolet. So Chevrolet are on their way out in Europe.
