The Audi Quattro concept is back!

The Audi Quattro concept is back!

No, you are not seeing double. This is, in fact, a refreshed and updated version of the Audi Quattro concept that had 1980s rally fans salivating back in 2010.

The German marque told the world's press that they had ditched the concept - despite receiving high praise from those lucky enough to drive - in favour of an electric car programme in the shape of the Audi R8 e-tron and the A3 e-tron.

But in a twist of fate, Ingolstadt officials have said that the majority of their activity at this year's Frankfurt motor show will surround the iconic Quattro four-wheel-drive system and possibly the unveiling of an updated Quattro concept vehicle.

Full details remain scarce (Audi wants to ramp up the excitement!) but it is thought the concept may be based on the Audi A5 platform, hinting at a possible production run.

Rumours also suggest that the 408bhp 2.5-litre, five-cylinder engine used in the original concept will be replaced with the fire-breathing lump found in the current RS Avant. That means around 600bhp from the massive twin-turbocharged 4-litre V8.

As with many modern supercars, the new Quattro concept will make the most of lightweight design, utilising materials such as carbon fibre and aluminium to keep the power-to-weight ratio high.

Sources told Autocar: "We have a great history with quattro four-wheel drive and this will be reflected by what we have in store for the Frankfurt motor show."

So could this signal an end to the R8 as Audi's range-topping supercar? Take a look at the Quattro concept sketches in the gallery below and then have your say in the comments section.
