WHAT is it, how much does it cost and where does it sit in the range? This car raises so many questions that Audi ought to call it the ‘A?’ not ‘A7’. Pitched against the super-successful Mercedes-Benz CLS as well as BMW's not-so-hot 5 Series GT (at least until the all-new 6 Series sedan arrives), this four-seater five-door supercharged V6 slingshot seems like the answer to something that nobody even thought to ask. So you can imagine our surprise when we found ourselves reluctant to hand it back.
