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.

Next BMW 7-series previewed in Vision Future Luxury concept

BMW has previewed key exterior styling elements, contemporary interior design touches, lightweight carbon fiber construction and innovative lighting systems to be incorporated on next year's sixth-generation 7-series with the unveiling of an arresting new concept car that goes under the name Vision Future Luxury. Revealed at the Beijing auto show, the big new sedan is described as a showcase for future BMW models. But while initial speculation suggested the Vision Future Luxury pointed at a possible 9-series flagship model to be installed at the top of the German car maker's lineup, BMW officials have confirmed the new concept was created more specifically as a pointer to the next 7-series, which is planned to head into North American showrooms late next year.

Maserati Ghibli

Maserati has unveiled the first images of the 2013 Ghibli ahead of its official debut next week at the Shanghai Auto Show. While the Ghibli badge has previously been reserved for coupés – both Giugiaro's 1967 original and Gandini's Biturbo-based 1992 Ghibli II – this is a four-door sports sedan to sit below the larger Quattroporte revealed in January at the North American International Auto Show. It's the first time the carmaker has built a car for the E-segment since the 1994 Quattroporte IV and is set to challenge high end of the Mercedes E-Class and BMW 5-series in AMG and M5 guises respectively.
