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.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

2016 Audi A4 is larger, lighter [w/video]

The 2016 Audi A4 arrives with a bang, but no surprises. We say that because the formula for creating the new A4 is one we know all too well. Make it larger, add a bunch of content, reduce weight, and improve both power and efficiency. It's a recipe for success, and this fifth-generation A4 looks to be a solid contender against its chief rivals, the BMW 3 Series and Mercedes-Benz C-Class. The shape hasn't changed; it's immediately recognizable as an A4. Instead, this new model updates that familiar design with sharper lines, similar to what we've seen on the new Q7, or even the R8. The big story here is that the 2016 A4 is up to 264 pounds lighter than its predecessor, depending on trim and engine. Additionally, the A4 is the most aerodynamic car in its class, boasting a drag coefficient of just 0.23. A fresh, modern cabin lies within that lighter shell – one that looks decidedly more upscale than the last A4. Many elements are reminiscent of the Audi Prologue concept that we first saw (and drove) in Los Angeles last year – specifically, the steering wheel, and the new MMI controls. In fact, Audi has positioned its infotainment controls closer to the center console – in front of the gear selector. This reminds us of the current A8, where Audi specifically designed its shifter to act as a sort of wrist rest. You can rest your arm on the gear lever and still access all of the MMI functionality. Speaking of which, that's the latest generation of Audi's MMI interface, packing navigation, touch capability, LTE connectivity, and WiFi in the 8.3-inch color display. Audi isn't saying which engines will come to the United States right now, but when the new A4 launches, it'll be offered with three gasoline and four diesel engines in Europe. Our best guess is that the US-spec car will come with the latest 2.0-liter TSFI turbocharged inline-four with 272 horsepower, as well as Audi's tried-and-true 2.0-liter TDI diesel four. Front- and all-wheel drive will be available, and for the first time, two-wheel-drive models will get a proper dual-clutch transmission – no more CVT. There's a whole lot more to lean about the A4 in the press release, posted after the reveal video. You can also see the 2016 A4 in sedan and Avant forms in the galleries above and below – it's unclear if the wagon will make its way to the US. The A4 Avant has been sold here before, but currently, Audi only offers that more functional bodystyle in Allroad spec.
