Audi A6 review - CarBuyer

You have to admire the new, 2011 Audi A6. Built out of more lightweight materials than ever, the latest A6 is faster yet more economical than ever while inside its incredibly classy cabin is chock full of all the gadgets you'd expect on a luxury car. There's a wide range of petrol and diesel engines, along with the option of quattro four-wheel drive too.
