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.

Which would you rather have, Audi's RS5 or Mercedes' C63 AMG 507?

If you're in the market for a German sports coupe with a naturally aspirated V8, run, don't walk, to your nearest dealer because they are going to be gone very soon. European fuel economy and emissions rules have conspired to force automakers into seeking forced-induction mills. Motor Trend personality Jonny Lieberman is hosting the retirement party in the latest Head 2 Head video, where he takes on the 2014 Audi RS5 and 2014 Mercedes-Benz C63 AMG Edition 507 to decide which is the ultimate Teutonic V8.
To make the decision harder, Lieberman challenges the duo on the first soaking wet roads that Southern California has seen in ages. It forces the coupes to confront some of the actual weather that the rest of the country encounters regularly and serves to even the playing field somewhat between the charismatic rear-drive Mercedes-Benz and the all-wheel drive Audi.
It really is the end of an era for these coupes. The next Audi RS4 is rumored to switch to a twin-turbo V6, and while Mercedes won't officially admit it, the next C-Class AMG will likely switch to a 4.0-liter twin-turbo V8. And we already know the next BMW M3/M4 will rely on a 425-horsepower, 3.0-liter inline-six. Let's enjoy these eight-cylinder German giants while we can, and scroll down to watch the video.

Audi A8 and S8 get another video tease

If there was any doubt before about which car(s) Audi recently teased in a video, now we know for sure. Audi has released another teaser video that confirms we'll at least be seeing the 2015 Audi S8 (and very likely the A8 as well) in the near future, but the big surprise is just how soon we'll see the new flagship sedan. We originally expected to see the sedan receive its official debut at the Frankfurt Motor Show, but now Audi says that the car will be presented about three weeks before the event on August 21.
How do we know this is the S8? Well, aside from it obviously being a large sedan, the true tell that this is its A8/S8 is the front license plate, which clearly shows "S8" on it - we've been doing this long enough to know that Audi's promotional license plates have the model designation in the plate number. As for other details, Audi's trick Matrix headlights shine through the thin veil in what should be the crown jewel of the sedan's new face. There's a little more than a week to go until the car is unveiled, but for now, check out the video below.
