Mercedes A45 AMG – with Lewis Hamilton & Nico Rosberg (video)

That lump is a 2.0 litre turbo 4-cylinder that produces a not insignificant 355bhp and 332lb/ft of torque, which is enough to get the pocket rocket A45 to 62mph in a competition busting 4.6 seconds. And with the A45 AMG heading towards Mercedes showrooms soon, MB are bust promoting their new hot hatch, and what better way to do that than rope in your own highly paid F1 drivers to add a bit of performance gloss? So Mercedes has put Lewis Hamilton behind the wheel of an A45, Nico Rosberg in the passenger seat and a ‘Good Fairy’ in the road to sort out arguments about who should get to drive.

Concept Car of the Week: Fiat Scia (1993)

After a successful design competition between famous Italian design houses to rework the little Cinquecento, Fiat renewed the experience two years later by giving to nine of them – including Fiat's in-house studio – a new Fiat Punto as a base to let their creative juices flow. The results ranged from being simply forgettable (Zagato Monomille), ridiculously daft (Boneschi Doblone) or just plain ugly (Giannini Punto 4x4 TL), but one of the concepts stood out from the flock for being brilliantly bold. This was the Fiat Scia, presented to the public at the 1993 Turin Auto Show.
