Driven: Cadillac XTS

In the light of the new, global-focused ATS and hot-off-the-press CTS sedans, the full-sized, US-centric Cadillac XTS is somewhat of an anomaly in the new Caddy clan.

Lamborghini Egoista (2013) first official pictures

Lamborghini's latest birthday present to itself is this: the crazy-looking Egoista concept. The one-off Egoista follows the Veneno and Aventador Anniversario in paying tribute to Lamborghini's 50th year in the supercar business, and is the most radical looking yet – it's so exclusive Lambo isn't even considering putting it up for sale.

New 2013 Bentley Continental GT Speed Convertible: Official

The Bentley Continental GT Speed Convertible, the drop top version of the GT Speed, has been officially revealed ahead of a Detroit Auto Show debut. Just as expected, Bentley has transplanted all the goodies from the latest version of the GT Speed in to the GTC Speed, which means a fulsome 616bhp and 590lb/ft of torque from the delicious 6.0 litre W12 and, despite gaining more than 200kg to keep the huge Bentley stiff without its roof, the GT Speed Convertible manages to hustle to 62mph in 4.1 seconds – just a tenth slower than the tin-top Speed. That extra lard does have more impact as you head towards 100mph with the convertible taking 0.7 seconds more, but there’s not exactly a paucity of power on offer.
