Audi readying 650-hp Sport Quattro Concept for Frankfurt

Remember Audi's perfectly lovely Quattro Concept from the 2010 Paris Motor Show? Of course you do. The latter-day Ur-Quattro is laser-etched in our brains as well - and not just because Audi was kind enough to offer our man Michael Harley a mountain drive of its seven-figure showcar. At the time, Audi hinted that the coupe might have a showroom future, but the gossip pipeline has long since gone dry, leading us to believe that the car's production hopes had soured.
That 2010 concept was powered by a 2.5-liter five-cylinder engine yielding 380 horsepower and 354 pound-feet of torque, a relatively modest but appropriate engine configuration in light of the Ur-Quattro's five-banger. Given the Quattro Concept's size and specs, it wasn't clear exactly where such a vehicle might fit into the company's lineup, though, as it already already offers the successful A5/S5/RS5 lineup.
Apparently, Audi might have a solution to that conundrum. A new report from Germany's AutoZeitung suggest that the automaker is posed to reveal a production version of the concept at the Frankfurt Motor Show in September - on the Ur-Quattro's 30th anniversary, no less. Word is that Audi is taking the Quattro Concept upmarket in a big way, with a tuned version of the twin-turbo 4.0-liter V8 from the RS7 churning up in the neighborhood of 650 horsepower. Naturally, all-wheel drive will get all that power to the ground, and new bodywork is expected as well. In addition to the powertrain switch-up, there is talk of extensive use of lightweight materials, including magnesium, carbon fiber and aluminum, with a target weight of under 2,900 pounds. Magnetic ride control suspension and carbon-ceramic brakes are also expected to find their way onto the model. Unsurprisingly, all of that extra equipment is likely to impact the car's bottom line - reports suggest its sticker price could crowd that of the mighty R8 at around $150,000.

Honda, Audi sweep European tin-top championships

Despite his win at the Japanese Grand Prix this weekend, Sebastian Vettel still has another race or two to go before he can claim his fourth consecutive World Championship in Formula 1. Back in Europe, however, this weekend saw several championship titles decided in a variety of tin-top racing series.
In the British Touring Car Championship, Gordon Shedden won the final round at Brands Hatch this weekend, but that wasn't enough to defend his title. Instead, the ultimate glory went to Andrew Jordan, also driving a Honda Civic, coming in ninth place to take a seven-point victory over Shedden in the final standings. Little wonder then that Honda took the constructors' championship and the Honda Yuasa Racing team took the teams' title. Four-time BTCC champion and Fifth Gear co-host Jason Plato, now driving for MG, landed third in the standings.
While Honda dominated the British championship, it was Audi that reigned supreme in mainland Europe. In the Superstars International Series - Italy's touring-car championship - Gianni Morbidelli drove the Audi RS5 to his fifth title, finishing the season's final race in a calculated third place behind the BMW racecars of Giovanni Berton and Max Mugelli. It's the second consecutive win for the RS5 in the Superstars series (Johan Kristoffersson won the title last year), and the second this year following Mike Rockenfeller's title in the RS5 DTM.

Mattias Ekstr?m unleashes bonkers 600-hp Audi S1 Supercar on World RX

Mattias Ekström doesn't need to prove anything. He's won the DTM title twice and before that the Swedish Touring Car Championship. But being a racing driver as he is, Ekström has been looking for new challenges. He's contested the Swedish Rally six times, the German Rally twice, he's driven in V8 Supercars and in NASCAR. He's even won the Race of Champions. Twice. Heck, we're surprised his long-time sponsor Red Bull hasn't let him try out one of its F1 cars. But this season it's on to a new challenge: the inaugural FIA World Rallycross Championship.
Ekström drove a Volkswagen Polo fielded by Marklund Motorsport in the Swedish rallycross round last season and came in second, but this year he's diving in head-first with his own team and his own car. His outfit EKS is hard at work preparing the new Audi S1 for competition in the World RX Championship, and will field two of them this season: one for Ekström and another for JWRC champion Pontus Tidemand.
Built to compete in the top category of the championship, the EKS Audi S1 Supercar will pack a 2.0-liter turbo four with 600 horsepower, all-wheel drive and a 0-60 time of 1.9 seconds. It's expected to make its debut late in May at the World RX of Great Britain where it will have to tangle with specially prepared versions of the Citroën DS3, Ford Fiesta ST and Peugeot 208 driven by the likes of Tanner Foust, Ken Block, Jacques Villeneuve and Petter Solberg. The sole North American round will be held in Trois-Rivières, Quebec, in early August, on the same circuit that once hosted Indy Lights, ALMS, Grand-Am, Can-Am and Trans-Am races.
