Nissan 350Z

	The large intake above the reg plate feeds air to the most significant extra – a Novidem supercharger. This boosts power from 296bhp to a huge 377bhp

The one-off model first appeared at July’s Goodwood Festival of Speed. Now, Auto Express has tried it to see if you should be pleading with your Nis-san dealer to let you buy one.

The most obvious change is the add-ition of an aggressive bodykit. It incorporates a rear spoiler and low front splitter to create genuine downforce, while wider alloys hide uprated Brembo brakes. With the sinister black paint, these give the GT-S a purposeful look.

There are plenty of visual clues to the changes beneath the skin. For instance, the large intake above the reg plate feeds air to the most significant extra – a Novidem supercharger. This boosts power from 296bhp to a huge 377bhp, and can be switched on and off using a button on the centre console.

As the blower clunks into action, the 350Z is transformed from a fast coupé into a junior supercar. Performance is electrifying – the 0-60mph sprint takes only 4.8 seconds compared to 5.8 for the standard model. Every time you pull away, it feels like you are leaving the pitlane; the mechanical whines and whirrs give the GT-S a race car feel. As the revs rise, an electronically controlled valve in the exhaust opens, too, providing a suitably sporty soundtrack.

The specially developed suspension is surprisingly supple, and smooths out bumps without harming the superb handling. Modified cars often come with ultra-stiff set-ups, but the GT-S has been tuned for UK roads, combining good body control with a pliant ride. The powerful brakes are reassuringly responsive, too, and the meaty steering is precise and provides plenty of feedback. Nissan’s robust six-speed box is unchanged.

Additional sound insulation boosts long-distance refinement, but the mech-anical nature of the supercharger is a constant reminder that you’re not driving the standard model. Leave it on all the time and it noticeably increases cabin noise – and fuel consumption – especially at motorway speeds. How- ever, its 425Nm of torque provides an addictive surge of acceleration at seemingly any speed.

If you’re not in the mood for go-faster performance, simply turn off the blower and enjoy the standard V6. Already convinced? Form an orderly queue!
