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.

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.

2014 Audi A4 next car to go on big diet while adding features

The Audi A4 is expected to receive a major redesign over the next couple of years, and with the smaller A3 now gaining a sedan model, it is being reported that the A4 might be getting a little breathing room for a more advanced design and improved technology and features. According to AutoBild, this would include a drop of more than 200 pounds in curb weight, updated cabin tech and a wider variety of drivetrain options.
AutoBild states that Audi is looking to upgrade just about every detail - inside and out - when it comes to the 2014 Audi A4, and this includes a next-generation MMI system that uses two digital displays. Extensive use of magnesium, aluminum and plastics will help shave an estimated 220 pounds from the A4's curb weight, and in terms of engines, it sounds like the usual array of forced-induction, small-displacement gas and diesel engines will be on tap, but a bigger V6 TDI and a plug-in hybrid powertrain are also mentioned.
