Walt Arfons: 1916-2013

No one seemed to know why the two brothers stopped talking, but their resulting rivalry led to some of the fastest cars ever built, two of which went more than 600 mph.

Audi Sport Quattro Concept arrives on video

It does seem almost a certainty that Audi are planning on building a production version of the Audi Sport Quattro concept we saw at the Frankfurt Motor Show last month. After all, Audi has already had one stab at a high-end recreation of the iconic quattro in 2010, turned up at Frankfurt with a second, more powerful, version and has now got that version running around on video to celebrate 100,000 Facebook Likes. If Audi are going to build the Sport Quattro it’s almost certainly going to be a limited edition run at a price that eclipses even the current range-topping Audi R8 V10 Plus.
