Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.

GM, Audi, Jaguar halt Russian sales amidst ruble's collapse

The value of Russia's ruble currency has sunk like a stone tossed in the Volga for much of the year, losing over 40 percent of its worth since June. The change is having bizarre effects on the auto industry there and leaving some automakers scrambling to adjust. According to Bloomberg, Russians are buying up luxury goods including automobiles at the moment to have a physical investment in case the ruble sinks further. However, with the money worth so little, the companies aren't making much from these transactions. Things are so dire that several automakers are temporarily ending deliveries until the situation stabilizes. According to Bloomberg, General Motors stopped sales on December 16 with no set date to start again. Audi did the same thing but with the intention to resume once it has adjusted model pricing. Jaguar Land Rover terminated business until December 19 to see how things changed. Toyota is increasing its pricing, as well, but keeping business open at the same time. Some automakers have subtly been reacting to the slumping Russian auto market all year. The moves have included Volkswagen cutting production by 30,000 units from its factory in Kaluga. Ford also got rid of 950 workers from two plants due to low demand. Some analysts have even speculated that the contracting industry and possibility of lower import duties into the country could cause companies to end their manufacturing in Russia completely.

Audi R8 lines up as safety car for Rolex 24 at Daytona

This weekend a new era begins in American sports car racing with the Rolex 24 at Daytona to kick off the new United SportsCar Championship, the freshly inked union between the Grand Am and American Le Mans Series. There'll be a wide variety of machinery lining up on the grid at the Florida speedway, including race-ready versions of the sports cars you can drive on the road, plus Daytona Prototypes, Le Mans Prototypes and even the DeltaWing. But at the front of the pack will be the Audi R8 5.2 FSI.
That's because Ingolstadt's flagship has been named as the official safety car for this, the 52nd annual Rolex 24 at Daytona. And so the R8 becomes the first pace car pressed into service for the United SportsCar Championship, although the model also paced last year's race (pictured above) when it was under the auspices of the Grand Am series.
The car in question appears to bear little in the way of modifications over the showroom version, save for some requisite graphics and maybe some emergency lighting to make it more visible - because while you wouldn't miss an R8 slicing its way through ordinary traffic on the road, it's another story entirely in a field full of competition machinery. Audi points out that the road-going R8 shares a good 50 percent of its components with the R8 LMS competing in the race, including its 5.2-liter V10 engine that's available this year with a new seven-speed dual-clutch transmission.
