Audi has gone back to the future with this, the Quattro Concept, which looks even closer to a possible future production version. While the concept drawings showed an angry, aggressive look, the “in-the-metal’ version is understandably toned down, yet still looks squat and purposeful.

We brought you conceptual drawings of the Quattro Concept not so long ago, with speculation on possible power and figures, and now Audi has confirmed more details.

Famed for dominating the World Rally stages, Audi will be hoping to trade on some of that nostalgia with this new model, most likely reaching showroom floors in late 2015.

And it will be quite the performer. A plug in hybrid, the Quattro will feature a 411kw twinturbo petrol V8, coupled to a 110kW electric motor for a combined output of 521kW and 800Nm of torque. To put that in perspective, the most powerful R8 in the current line up, which uses a larger V10 motor, offers 404kW and 540Nm.

New Audi Quattro Performance Figures

Audi is claiming acceleration of 0 – 100km/h in 3.7 seconds and a top speed of 302km/h. However the plug-in hybrid set up gives the car astonishing fuel consumption; Audi claims 2.4litres/100km and CO2 emissions of just 59g/km.

Those figures are curiously close to the figures claimed by BMW’s i8 which we featured yesterday; a new future rivalry is certainly on the cards, but for the moment, the Audi trumps the i8 on power and performance, while the BMW will most likely get closer to it’s stated efficiency claims.

Although extensive aluminium and carbon fibre reinforced plastic (CFRP) have been used throughout, the Quattro Concept still tips the scales at 1850kg, including the battery pack. That’s a fair bit of weight to carry around, and gives a clue as to why the car has so much power.
