2013 Nissan GT-R gets a tweak

Nissan has had a play with the GT-R for 2013 with suspension upgrades, sharper responses and a more comfortable ride. On the performance front, the 2013 model year Nissan GT-R gets a set of new high-output injectors which give more concise control to fuel for better mid range and high rev response, a new relief valve for the turbocharger bypass cuts the decrease of pressure to sustain response and a new oil pan baffle helps maintain oil pressure. On the handling front Nissan has revised dampers, springs and the front anti-roll bar to lower the centre of gravity, new cam bolts on the front suspension improve accuracy and the torque carrying capacity of the driveshaft to hub bearings has been increased to you can attack a track more reliably.

Porsche 911 testing in the extreme: Video

The new Porsche Carrera 911 might not look much different from the last-generation car. It might not even look much different from the first generation. That doesn't mean the company just flips a switch and the new version is born.

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.
