Microsoft demos Apple CarPlay rival

The battle between Microsoft and Apple is being fought on the desktop, on the smartphone and now in the car. At its Build 2014 developer conference, held earlier this month in San Francisco, Microsoft demoed an early version of Windows In The Car, its response to Apple's CarPlay system we saw at the Geneva Show back in March. As you'd expect, In The Car's design follows the look of Microsoft's latest Windows and Window Phone operating system pretty closely.

Fiat 500: US Spec Fiat 500 revealed in LA

U.S. Spec Fiat 500 revealed at the Los Angeles Motor Show It would have been completely unthinkable just a few years ago; a small Fiat not just entering the US market but doing so amid much domestic anticipation and razzmatazz. But it’s happened – the car buyers of America have been introduced to the Fiat 500 at the Los Angeles Motor Show.

Volvo S60 Polestar goes in to production

It sounded like a plan to put it in to production – even if it would probably need twin turbos to make it nicely wieldy on the road – and that’s exactly what Volvo and Polestar have done. The Volvo S60 Polestar has gone in to limited production, initially for the Australian market, but instead of the mighty 508bhp of the concept it has to make do with a more pedestrian 350bhp, little more than the V60 we reviewed last year with the Polestar upgrade. But the extra power is enough to get the production S60 Polestar to 62mph in 4.9 seconds and, thanks to tweaks to the suspension, brakes and aerodynamics, the S60 Polestar looks like it will be able to handle the power quite well.
