I’m not really into campaigns, but I reckon Autocar readers might be able to influence one of the great decisions pending in a car company in-box.

At some point in the next few years, Alfa needs a new Spider, Duetto or whatever you call it — a lightweight agile, two-seater, preferably rear-drive.

And at Geneva, Italian coach-builder Pininfarina served up the perfect design – the beautiful Duettotantta — several design bosses’ choice of best car at Geneva.

If there’s any justice on the world, the Duettottanta will pass unhindered from concept to production as fast as Alfa Romeo’s engineers can manage. The exquisite proportions and subtle body surfacing surely demand that?

Pininfarina talks about the Duettotantta as a “single volume”, which seems to me to be shorthand for an incredibly fluid beltline that flows seamlessly from the rear haunch into the centre section and on to the minimalist Alfa shield grille.

Pininfarina’s own pictures don’t really show the scalloped detail on the body side, but it’s the same feature that made the Ferrari Scaglietti so distinctive. Scaled down on the smaller Duettotantta, it just looks right.
