Job number one for me at this year’s Detroit motor show was to head downtown to the city fire station and witness the unveiling of VW’s new mid-sized saloon, designed exclusively for the US.

Rather confusingly it’s called the Passat, and it does share plenty of mechanicals with one that patrols our company car parks.

But it's been tailored to compete with the likes of the Ford 500, Hyundai Sonata and Toyota Camry in the world’s toughest car market. Like its main rivals it will be built in the US at an all-new factory in Chattanooga, Tennessee where up to 150,000 of the them will be rolling off the line every year, with the possibility of quite a few more if sales are good enough, according to plant boss Frank Fischer.

So what's it like? Well I'd like to be able to tell you but VW's big cheeses didn't feel like it was appropriate for the actual car to be at its launch party. But I've seen enough to know that it looks smart.
