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.

Porsche uses phone-formatted bar codes to connect with customers

Porsche is harnessing the power of smartphones, using Microsoft Tag bar codes to provide dealership customers with unique information about the cars they're looking at. Buyers can scan the square stickers with a properly equipped phone, and the application will take them to dedicated microsites where they can see stats, videos and pictures of the car, along with audio clips of a flat-six engine revving up. Through the microsite, buyers can provide contact info for a follow-up call from Porsche salespeople.
