What is it?
The Mazda’s MX-5 Superlight concept – which is taking centre stage on the Mazda stand at the Frankfurt motor show, and which we’ve driven.
It’s a low-emissions, stripped-out, driver-focussed one-off version of the world’s biggest-selling sports car.
The car’s story began when Mazda Europe Head of Design Peter Birtwhistle, designer Hassip Girgin and the team took a 1.8-litre MX-5, stripped it down to its bare essentials – a running chassis with essential body panels only – and invited Mazda’s test engineers to drive it.
Those test drivers reported that the MX-5’s key dynamic traits – its trademark sharpness of response and natural rear-driven handling balance – were only enhanced by the lack of weight.
So they duly set about replacing some of the components they’d taken away with lighter alternatives made from carbonfibre and aluminium. They left the windscreen and roof off altogether, and fitted an alumium bonnet with a carbonfibre extension that incorporates the rearview mirror and covers the instrument cowl.
In place of the soft top, the Superlight has two large rollover hoops with integrated wind deflectors. And because the car is always roofless, the doors don’t need exterior handles. To open them, you pull a leather tie inside the cabin.
Also inside the cabin, the instrument panel is made of fiberglass-reinforced plastic; the gearlever and handbrake out of aluminium partly covered with leather. There’s no HVAC system at all, and no noise and vibration isolation either.
All in all, Mazda’s crash diet has taken 160kg from the kerbweight of this car; as a result it’s half a second quicker to 62mph and 6mpg more fuel efficient too.
What’s it like?
Exposed. That’s how you feel when you strap yourself in. There is no windscreen in front of you, no interior trim panels on the doors. And ahead of you, where the CD player should be, there are two flip switches – one to turn on the fuel pump, the other the ignition – and a starter button. That’s it.
