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.

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.

Audi RS3 spy shots foreshadow an ultra-hot hatch

Not all vehicle prototypes and mules require heavy camouflage - sometimes they can be hidden in plain sight. That's probably what Audi was hoping for while testing its new RS3 wearing S3 duds, but thanks to some visual and audible telltales, our spy photographers were able to recognize this as a precursor to the marque's ultra-hot hatch testing near the Nürburgring.
Our photographer noticed the signature exhaust note of a five-cylinder engine, which suggests the RS3 could borrow its motivation from the excellent TT RS. Producing at least 340 horsepower, this 2.5-liter turbo powerplant could be the perfect answer for the new A45 AMG from Mercedes-Benz. The big brakes on this RS3 mule give us our best idea about the car's high-performance intentions, with Audi RS wave brake rotors and six-piston calipers peering out from behind the oversized wheels.
In production form, the RS3 should have a much different appearance from what you see here, with sportier design cues including oval-shaped dual exhaust outlets and a more aggressive front fascia. While we're still waiting for our first taste of the S3 in the North America, we'll be holding our breath for the RS3 to make its way here, as well.
