More details on next Audi A4 mooted, including PHEV

With just under two more years until the next-gen Audi A4 hits the streets, it's not surprising that details are starting to leak out. The Brits from Autocar are reporting some information on the 2015 A4, although it isn't clear where any of it came from.
The most substantial news might be in regards to the plug-in hybrid version of the car. We've known for a couple years now that an A4 PHEV was being planned, but the report indicates that a trio of plug-in configurations are being planned, equipped with a 2.0-liter gas engine, a 2.0-liter diesel engine or a 3.0-liter supercharged V6. All engines will be paired with an eight-speed automatic transmission, and the A4 plug-in is said to have an all-electric range of up to 31 miles.
In terms of styling, the next A4 shouldn't stray too far away from Audi's current design language, but it will introduce a new version of the automaker's signature grille. Despite being about the same size as the existing A4, the fifth-generation model will drop some pounds thanks to various weight-saving techniques with the most obvious being aluminum body panels. Based on this info, we should see the A4 sedan and wagon in April 2015, an Allroad later in the year and a redesigned A5 lineup hitting the scene in 2016.

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.

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.
