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.

Tom Kristensen walks through a perfect lap of Le Mans in Forza 5

One of the best ways of learning a new track, aside from driving it, is to hear someone that's intimately familiar with it give you a good walkthrough. That's just what you'll get here, as the winningest driver in 24 Hours of Le Mans history, Tom Kristensen, walks you through the Circuit de la Sarthe's high-speed, 8.5-mile strip of pavement.
Kristensen is dubbed over scenes of drivers from a Forza Motorsport 5 contest lapping the track at the wheel of an Audi R18 E-Tron Quattro, adding a bit of visual sense to the Danish drivers description of the track.
With the 2014 24 Hours of Le Mans kicking off this weekend, this is just the sort of video you'll want to watch to get you in the mood. Take a look below, and then let us know what you think in Comments.

KTM X-Bow to get Audi TT-RS five-cylinder turbo

The Audi TT-RS continues to occupy a warm spot in my personal top five list of cars thanks in no small part to the lusty turbocharged 2.5-liter five cylinder under the hood. With 360 horsepower and 343 pound-feet of torque in stock configuration, the engine is a shining star of internal combustion. And now it's headed to one of our favorite vehicles. EVO reports KTM is planning to plop the turbo 2.5 from the TT-RS into the upcoming X-Bow. That ruckus you hear? It's a choir of angels singing "Halleluiah." While speaking at the Geneva Motor Show, KTM CEO Stefan Pierer said the engine is good for up to 480 horsepower.
Pierer went on to say that the company is already testing prototypes and that we may very well see the engine show up in some races next year. What's more, the company's engineers are playing with dual-clutch transmissions, too. Since KTM is already testing the turbo 2.5 on the track, it's only a matter of time before customers will be able to get their grubby mitts on a street-legal version.
