Audi Sport Quattro Concept to spawn volume sports car?

There have been two modern re-imaginings of the original 1984 Audi Ur-Quattro: the Quattro Concept of 2010 (shown above) and the Sport Quattro Concept revealed at the 2013 Frankfurt Motor Show. In between them, there have been numerous rumors about what, if any, kind of production car Audi might make of them. According to a new report in Auto Motor und Sport, Audi CEO Rupert Stadler has "indicated... that the car will come," and based on the specs presented, what we get might end up being a mix of the two.
Ulrich Hackenberg, Audi's head of R&D, apparently wants a sports car with wider appeal than the 700-horsepower hybrid Sport Quattro Concept. AMS says his vision would be built on a modified A6 platform - the same MLB architecture under the Sport Quattro Concept - with ample use of carbon and aluminum keeping the weight down to around 1,300 kilograms (under 2,900 pounds). Engines could include a 2.5-liter, five-cylinder (like that of the original, smaller Quattro Concept) offering anything from 310 to 360 hp. Those numbers would be at least 48 horsepower shy of the first concept, but a less-powerful entry point to a new model range would provide a lower cost of entry. Besides, a full model range would likely include a significantly healthier powertrain option on the top end.
At the moment, Hackenberg is said to be unsatisfied with the design of the car, which could well mean we'll get another concept car before a production version appears.

Audi rumored to ditch Le Mans, DTM for F1

If you've been scratching your head wondering how - between Audi and Porsche - the Volkswagen Group could possibly support two rival top-tier LMP1 programs at Le Mans and the FIA World Endurance Championship, but stay out of Formula One entirely, you're not alone. In fact, Porsche was said to have been eying an F1 entry if Audi had internally blocked aspirations to return to Le Mans. But according to the latest rumors, it's Audi that's now preparing to shift away from endurance racing and onto the grand prix circuit.
Word has it that, following internal pressures from within the VW Group, Audi is finally gearing up for a full assault on F1. It's said to be developing a new six-cylinder turbo hybrid power unit - potentially at its new racing headquarters in Neuburg - and, in an expanded partnership with Red Bull, either take Renault's and Infiniti's places with the Red Bull Racing team or take over the Toro Rosso team entirely.
Although Ingolstadt has not campaigned in grand prix racing since the pre-war days of the Silver Arrows, it was said to have been the impetus for the FIA's push a couple of years ago for new four-cylinder engine regulations until Audi bailed on the idea altogether and F1 went for six-cylinder engines instead.
