Winterkorn vacates chairs on Audi, Truck & Bus boards

The last remaining vestiges of Martin Winterkorn's power within the Volkswagen Group are slowly melting away. The former chairman of the group's management board resigned as CEO nearly two months ago in the wake of the diesel emissions scandal. He held onto other roles within the group, but one by one he's been vacating those as well. Last month Winterkorn resigned from his role at Porsche SE – Volkswagen's largest shareholder. Now the latest development comes from Bloomberg, which reports that Winterkorn has stepped down from his role as chairman of the supervisory board at Audi. Prior to his promotion to run the entire group, Winterkorn served as chief executive of the Audi division, and prior to his resignation served continued to serve as its board chairman. No date was given for his resignation from that capacity, nor any successor named at this point. Repeated requests for clarification from Audi have gone unanswered. In correspondence with Autoblog, however, spokespeople for VW's commercial vehicle operations confirmed that Winterkorn has also stepped down as the chairman of the board at Truck & Bus GmbH. The newly established division encompasses truck manufacturers Man and Scania. Winterkorn also served as chairman of Scania's board, but requests for confirmation of his departure from that role also went unanswered. The Swedish truck manufacturer, however, named Henrik Henriksson as its a new chief executive only a few days ago.

AMS Alpha 10 Audi R8 First Drive [w/video]

Horsepower is a relative number. Compared to the 1,500 hp in the last AMS car we drove, the face-melting Alpha 12 GT-R, 900 seems pretty tame. But by any rational standard that's a crazy amount of power, the kind that's hard to grasp in practical terms. When AMS Performance called us and offered a test in the 921-hp Alpha 10 Audi R8, saying yes was easy. Figuring out how to demonstrate that much thrust was the tricky part. Our solution was to head to the drag strip. What better way to show off the wicked alterations wrought by AMS president Martin Musial and his team than a video showing the car do the Star Trek warp speed effect through the quarter mile? AMS has a history of building quick drag strip cars, like the aforementioned GT-R and a series of Mitsubishi Lancer Evolutions. Vice president Arne Toman even owns the world's fastest Hearse. We should have taken the broken scoreboard at Milan Dragway as an omen. Wiped out by a lightning strike, both displays have since been replaced. Before our test both Musial and Toman explained that the Alpha 10 R8 wasn't built with drag racing in mind. But, being good sports, both met us at the track in southeast Michigan, unloaded the R8 from its trailer, and let us run through the timing lights over and over. The best time that day was 11.0 seconds at 136 mph, uncorrected. One of the many amazing things about the Alpha 10 Audi R8 is that it's essentially a bolt-on system. That's fast, but not what you'd expect for 786 horsepower at the wheels. And, honestly, we're not disappointed. First, a 4,200-rpm rev limiter was set too low to launch on the sticky drag strip. Put another way, that drag strip time is almost a street start. For what it's worth, Musial and Toman didn't seem concerned about the numbers. Like we said, they present the Alpha 10 as an all-around performance car, and we believe them. Now, if you go to AMS with the drag strip in mind, Musial and his staff can program whatever launch rpm you desire. (You're on your own for clutch replacements.) A reflash of the engine controller is part of the Alpha 10 package. Drop off a stock R8 V10 at AMS (or any of its 70-plus dealers), and they'll pull out the suitcase-shaped muffler that sits behind the engine. A pair of turbochargers, small mufflers, and two heat exchangers attach to the stock exhaust system mounts, while a giant water-to-air intercooler sits on top of the engine.

Audi 4.2-liter V8 to live again in next-gen R8

Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Word is that Audi's stupendous 4.2-liter V8 will once again be available in the next-generation R8. Rumors pegged the trusty 4.2 as a dead engine revving, thanks to Audi's newer 4.0-liter twin-turbocharged V8 found in models like the S6 and S7.
We expected the 4.0-liter to be the go-to engine in the next R8, but according to Car and Driver, there have been some issues cooling the force-induced mill in the mid-engine R8. The issues are so severe, in fact, that the 4.2 is going to be retained in the car's second generation.
It's more than just practical matters like cooling that are keeping the R8 from going turbocharged. C/D reports that even with the current state of forced induction, a turbocharged R8's throttle response and its resultant exhaust note would suffer too much to be feasible.
