Mercedes G63 AMG 6×6 vs G63 AMG (video)

Mercedes G63 AMG 6×6 vs G63 AMG The Mercedes G 63 AMG is a mad car in its own right (although not as mad as the G 65) and costs almost £125k before you start ticking any option boxes. But the G 63 AMG is bullet proof, will go anywhere and does come with many of the luxuries you’d rightfully expect in a £125k car, even if its on-road handling – particularly if you decide to make the most of the 5.5 litre V8 turbo’s  performance – is pretty woeful round the bends. Mad and irrational though the G 63 may be, it now has an even madder sibling – the Mercedes G 63 AMG 6×6 – which not only adds an extra axle for 6WD but comes at a price – almost £400k – that makes the G 63 seem a bargain.

Nissan Extrem concept

Nissan has unveiled its Extrem concept at the Sao Paolo motor show, a two-door 2+2 crossover that previews future Nissan design cues. The Extrem concept was designed at Nissan Design Center (NDA) in San Diego, California, in collaboration with Brazilian designers but much of the creative time was spent in Sao Paolo. "We call it Baby Beast," said Robert Bauer, Senior Design Manager for the project at NDA.

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.
