It's 2006 and the phone at Nissan's Technical Centre in Cranfield is ringing. Nissan's UK PR department is on the line, asking if the Cranfield engineers would be interested in creating a go-faster version of the already potent Nissan 350Z for the Goodwood Festival of Speed. Absolutely, the engineers reply, very interested.

The result is the car you see in the pictures above. At first glance, it looks like a standard 350Z. Until you notice the aggressive bodykit, the huge air intakes cut into the front bumper, the updated brakes and the high-set rear spoiler. Then you open the bonnet and discover that resting alongside the standard 3.5-litre V6 engine is something new - a supercharger.

This is the secret of the 350Z GT-S concept: a supercharger that boosts the car's power from around 300bhp to 382bhp. It also drops the 0-60mph time from an already quick 5.8sec to 4.8sec. In other words, this 350Z is quicker to 60mph than a V6-engined Jaguar F-Type and only 0.2sec slower than a Porsche 911 Carrera.
