LA Auto Show highlights - Cadillac XTS

Okay, so British buyers won't get this one. However, Cadillac's XTS – a 5 Series-sized model – is interesting because of its ultra-sharp concept looks and a cabin that's surprisingly coherent.

The show car is a range-topping model, true, but there are lots of soft-touch materials inside and the finish looks good.

The XTS takes some of its mechanicals from the same platform that sits under the Saab 9-5 and Vauxhall Insignia, although it's modified and will also be offered with four-wheel drive. There's no diesel, though, and Cadillac won't commit to European sales, let alone a right-hand-drive version.

Instead, the firm is concentrating on the ATS, a 3 Series rival that's due at the Detroit show in January. It will get right-hand drive, and diesel engines (likely to be Vauxhall units). If it can deliver a little of the XTS's edgy styling and still retain a half-decent interior, it could be an interesting proposition.
