Chevrolet Cobalt

The Cobalt is yet another Chevrolet making its debut at the Buenos Aires International Motor Show. Reviving the previously defunct name, the three-box Cobalt has been developed by GM's Technical Center in South America. Finished in a 'smoke beige' hue, the show car is said to be the result of research that showed cutomers' desire for more internal space paired with increased refinement and equipment.

Audi Urban Concept

Audi has released additional photos and information on the Urban Concept, which is set to make its debut at the Frankfurt motor show in September. As we previously reported, the new car – touted by Audi as a 'new kind of concept car' that combines aspects of a racing car as well as a fun-to-drive urban vehicle – is a diminutive two-passenger vehicle powered by two e-tron electric motors. Measuring in at 3200mm long, 1700mm wide and 1200mm tall, the Urban Concept is expected to weigh less than 500kg, thanks largely to a cockpit made from CFRP.

Aston Martin V8 Vantage N430 and DB9 Carbon for 2014 Geneva Motor Show

Aston Martin will show off special new versions of the V8 Vantage and the DB9 at the 2014 Geneva Motor Show in March. The updates to the two model ranges are very different in character, however. The V8 Vantage N430 is a race-inspired special with more power and less weight – not to mention a somewhat shouty paint job – while the DB9 Carbon Black and Carbon White models are intended to bring a little extra luxury and style to the British marque’s Grand Touring model.
