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 recalling 70k TDI models worldwide over braking problem

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.
The report indicates that while the brakes in these vehicles still function, the enhancing power from the booster may fail due to a possible leaky membrane.
All of the affected vehicles are powered by the 3.0-liter TDI turbodiesel V6, and were built between March and December of 2012. It is unclear as of this writing how many of these vehicles are in the States, though remember, US customers are not privy to 3.0 TDI examples of the A4 or A5. Autoblog has reached out to Audi for specific numbers, and we'll update this space when we hear more.

Recharge Wrap-up: Chevy Volt named KBB "Best Buy," slow BMW i3 sales in Germany

The Chevrolet Volt has been awarded Kelley Blue Book's Electric/Hybrid Car Best Buy for 2015. KBB cited the car's electric commuter capabilities, extended range, acceleration, design and overall value as reasons to place it above the Nissan Leaf, BMW i3 and Toyota Prius. It works well in the real world, and doesn't leave drivers with range anxiety. Plus, it's comfortable, and a fun car to drive, according to KBB. Read more at Kelley Blue Book. The BMW i3 is seeing slow sales in Germany. BMW has sold about half the number of i3s it expected in its home country, with about 1,900 sold in the first nine months. BMW projected sales of 5,000 to 6,000 in the first year. BMW partly blames long shipping times for the slow sales, and the company is offering incentives in hopes of getting more people to adopt the electric car. In the US, BMW sold more than 1,000 units each month between August and October. Read more at Green Car Reports. Audi is pursuing new carbon-neutral synthetic fuels - or e-fuels - such as Audi e-diesel. Audi's newest project uses electrolysis of water to create hydrogen, which it then reacts with CO2 extracted from the air. The result is a liquid - called Blue Crude - full of energy from hydrocarbon compounds. The Blue Crude can then be converted into a sulfur-free synthetic diesel called e-diesel. This e-diesel can be used as a drop-in fuel, blended into fossil diesel for a more renewable fuel. Read more at Hybrid Cars. Uber is partnering with Spotify to allow passengers to choose what music they listen to during their ride.
