To know Audi’s Quattro Concept, you have to recall the original Audi Quattro (a.k.a.”Ur-Quattro”) from 1980. Launched 30 years ago, the two-door coupe was the first sports car to feature the automaker’s new Quattro all-wheel-drive system. With a turbocharged 2.1-liter inline five-cylinder engine mated to a five-speed manual transmission, the original 200-horsepower street variant was good for a 0-60 sprint of around seven seconds and a top speed of 137 mph. Rally-prepared, and with hundreds of additional horses under the hood, the Audi Quattro was unstoppable, dominating the Group B class in rally competitions around the world for years. Commemorating the success of the legendary Audi Quattro, the engineers and designers at Audi set out to develop a modern interpretation – an homage – to the classic. Their efforts were unveiled at the 2010 Paris Motor Show. Check photos of the new concept after the jump. @FunkmasterFlex

Sometimes, the children just refuse to get along, leaving it up to the parent to swoop in, clean up the messy bits and make a judgment. Such is the case at the Volkswagen Group, where corporate stepchildren Audi and Porsche were both fighting for the right to develop future sports cars and luxury sedans for the German auto conglomerate’s portfolio of brands. @Funkmasterflex

The KTM 350 EXC-F Factory is works-rider-only racer that will be used to develop the Austrian bike maker’s next-generation enduro models. Like the KTM 350 SX-F that just won the MX1 world title, the new 350 is claimed to make the power of a 450 and weigh only as much as a 250. @funkmasterflex

The New Stratos is here to suggest that you may be able to have your cake and eat it to, as full technical specifications and performance stats have been released on the one-off retro creation. The aluminum chassis from the Ferrari 430 Scuderia is a good starting point, giving the New Stratos a compact, lightweight frame, a 44/56 front/rear weight distribution ratio and a 4.3-liter V8 tuned from the 508 horsepower delivered in the Scud to 540 in the nuovo Lancia. @funkmasterflex
