Next Audi R8 to be up to 130 pounds lighter

"Simplify and add lightness," as Lotus founder Colin Chapman said. In a world where even supercars are subject to environmental, efficiency and emissions standards, lighter vehicles are being looked on as a sort of panacea - make it lighter, and it's automatically faster, more agile, easier to brake and better on gas.
Knowing this, it comes as no shock that Audi is looking at ways to lighten up its next-generation R8, with the brand's head of technical development Ulrich Hackenberg targeting a 110- to 130-pound diet for the mid-engine rocket. This supports previous reports regarding the focus for the next R8. Motor Trend reports that aluminum and carbon fiber feature heavily in plans for the next R8, which should go a long way toward slimming down even the lightest of R8s, the 3,678-pound V10 Plus model.
There's more over at Motor Trend, including the buff book's attempts to get Hackenberg to discuss powertrain options for the next R8.

Audi supercar not yet approved, R4 not quite dead, still room for an MPV

According to a report by Autocar, all we thought we knew of the in-development Audi supercar we might not actually know. A piece in Car and Driver, not even a month old, said the diesel-hybrid halo car was in the design stages, would get the engine from the R18 E-Tron Quattro and its carbon fiber tub. Now we get word that that while the coupe is indeed being designed, it hasn't yet been signed off and there's no business case for it yet. Said business case, whenever it is built, is also dubious of the diesel aspect of the car at the moment - diesels aren't known for creating Pavlovian purchase responses in buyers in the two key markets of the US and China.
The report suggests that instead of a diesel, the 2014 Le Mans regulations changes "could swing the favour back towards petrol models," which would give the so-called Scorpion a better tie to racing technology. Of course, that also assumes that Audi would contest next year's Le Mans with a gas-powered car. If so, that would be an about-face on the original reasons for the halo sportscar in the first place.
In other news, seems Audi also believes it can slot another sportscar below the R8, it just needs to get the financials sorted. The R4 - a Porsche Boxster-sized roadster - that has been chattered about for years is still in on the table but appears a long way off. Company R&D chief Wolfgang Durheimer said it would need to be mid-engined and bring plenty of tech to separate itself from the TT, but mass-market price point is the catch as is the focus on other segments in the portfolio.

The real reason Audi races

The world has watched Audi have its way with endurance racing since 1998. What started as an intriguing race winner in 2000 that could be rebuilt so quickly that the ACO oversight organization changed the rules to slow Audi mechanics down, slowly morphed into a unique assassin, employing novel engineering methods to achieve series domination with its R18 E-Tron Quattro. Until recently. It's strange, then, that for all these years we didn't fully comprehend Audi's stated approach to motorsport. And so we sat down with Dr. Wolfgang Ulrich, head of Audi Motorsport, and Chris Reinke, head of Le Mans Prototype development while in Austin, TX, for the Lone Star Le Mans and World Endurance Championship race for answers. BMW, Corvette, Porsche, and Ferrari have healthy reputations, lucrative option sheets, and supported a robust trade in special editions by winning races. They have standalone racing divisions and they transfer the entire sheen of their racing endeavors to their road cars, a healthy part of what their customers buy into. Even though we know they improve their road cars with lessons learned racing, the belief is that they race because that's just what they do; those brand names mean racing. "Not one single euro is spent on a separate motorsports program." Yet Reinke said that for Audi, "Not one single euro is spent on a separate motorsports program. We [Audi Motorsport] are part of the Technical Department [of the road car company]. We are a pre-development lab for road-relevant technology." As in, Audi isn't racing out of core philosophy, it's racing only to improve its road cars. That helps explain why Audi's entire road car lineup doesn't bask in the same racing aura as those other brands even though Audi has been racing since it was called Horch. It's not a racing brand, it's a technology brand. Said Ulrich, "Instead of components, look at technologies – not lights, but lighting technologies, not engines, but engine technologies, like injection pressure technology is the same from the race car to the road car." That's nowhere near as exciting as, "Win on Sunday, sell on Monday," but it is arguably much more practical. Quattro is the most obvious example of racing tech for the street. For a less obvious one, Reinke said, "Audi Motorsport developed codes for computational fluid dynamics, and then we'd run the calculations on the Technical Department computers at night.
