New Mercedes A45 AMG has 105 years of 4WD on its side

With the new Mercedes A45 AMG on the horizon – complete with 4WD – Mercedes chart the history of all wheel drive on their vehicles. We tend to think of 4WD road cars as a modern innovation, and certainly very few 4WD road cars hit the road in a mainstream way much before the 1980s (the Jensen FF was hardly mainstream before someone points out that was in the 1960s).

Audi SQ5 Exclusive – for when an SQ5 just isn’t enough

Audi are debuting a limited edition of their new SQ5 – the SQ5 Exclusive – at Paris 2012 before a limited production run of 50 cars. The new Audi SQ5 – a diesel RS Q5 in all but name – bowed in at Le Mans in June featuring the 3.0 litre twin turbo diesel V6 with 479lb/ft of torque, 309bhp and a very un-SUV 0-62mph of 5.1 seconds. As the range-topping Q5 you would think that would be enough for Audi, but it seems they think there’s a market for an even more exclusive Audi SQ5 so they’re producing a limited edition model that’ll cost an extra £30k – the Audi SQ5 Exclusive.

It's the first car designed by Jason Castriota, the new design chief.
