Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

Audi A3 supplies tight, model stealing Honda, Toyota sales

It appears that there was a pent up demand for compact, front-wheel drive German luxury sedans that no one really knew about. Not only has the Mercedes CLA-Class been a success in the US with its Hungarian factory running three shifts to keep up, but the Audi A3 Sedan is doing quite well, too, after just three full months on the market.
Audi of America recently announced that the compact sedan shifted 2,452 vehicles in June and 7,735 units of the A3 since the beginning of the year. Not only are they selling; it's the people buying them that's important. According to Audi USA spokesperson John Schilling speaking to Autoblog, "A little over 25 percent of A3 buyers in April were 30 years or under." That's compared to about 18 percent for the A4, he said. Company executives also recently told Edmunds that many of those new customers are brand conquests turning in Honda or Toyota models. We gently mocked Audi when it held A3 Sedan launch parties aimed at hipsters that served craft beer and played indie music, but the marketing worked, apparently.
That said, if you're in the market for an A3, you might have not be able to get one immediately. According to Edmunds, some customers are on a waiting list for the compact luxury sedan. Although, Schilling said that's because Audi is still stocking dealers. "It's a little leaner than other models, but that's mainly because it's new and still ramping up," he said.

Evo drives the Audi R18 E-Tron Quattro on track

Audi invited Evo scribe Richard Meaden to the Misano circuit in Italy to drive the Audi R18 E-Tron Quattro - and not just any R18 Quattro, were such a thing possible, but the No. 2 car that took first place at Le Mans this year driven by Marcel Fassler, Andre Lotterer and Benoit Treluyer. Meaden got just four laps in the diesel hybrid racecar - a warm-up, two hot laps and a cool down lap - so this wasn't about testing the R18 E-Tron's limits. In fact, Meaden makes it clear that such a thing isn't even possible for less than a professional driver; when driving at his limits (admittedly in Audi's very expensive car being watched by dozens of Audi engineer eyeballs), the data showed he was using 60 percent of the pedal effort of the professionals. Nevertheless, Meaden does have a lot to say about how the car delivers its massive ability, and with the wide-view shot of the cockpit we also get to see how busy and how intimate an endurance driver's office is.
