There is a change in outlook at Audi, and I think it's going to be one for the better. The people who recently brought you the 571bhp, 2025kg RS6 are deadly serious about cutting weight from their cars.

That much they've made evident by keeping the headline weight of the Quattro Concept car, which I'll be driving today (and you can read about here later) down to 1300kg, the same as the original 1983 Sport Quattro.

On a concept car that's easy enough of course; replace enough metal with carbon fibre and you could have a one-tonne supercar if you wanted (as Lamborghini did with the Sesto Elemente, using quicker and cheaper processes than usual that, crucially, are near production-ready).

But Audi is making the right noises about doing it throughout its range; and not all through the use of exotic materials.
