Audi reveals even more efficient 2015 R18 E-Tron Quattro

We've seen two of this year's LMP1 manufacturer challengers – Porsche's updated 919 Hybrid and Nissan's GT-R LM Nismo. Audi has finished cooking up the successor to its Le Mans champion and unveiled the fifth-generation R18 E-Tron Quattro, even better than before. The bodywork monocoque is carried over, but the body around it has been reshaped to improve airflow from front to rear with a new hood, front fenders and wheel arches, and radiator configuration. The engine cover behind the cockpit is shrunk more closely around the engine, and there are new headlights. The hybrid system can expend double the energy per lap this year, putting Audi in the four-megajoule class under the energy-use regulations. That extra energy will come from 17-percent more capacity built into the flywheel storage system and an electric motor good for 272 horsepower. The revisions haven't increased the weight of the car, pegged to the minimum allowed at 870 kilograms. They have, however, forced changes to the TDI engine, which has to use 2.5-percent less fuel per lap to offset the increased hybrid output. The 558-hp V6 has been optimized such that it "managed to more than compensate for the loss" of fuel allowed, and Audi expects "significantly" lower lap times this year and less fuel used. We're still waiting to see what Toyota has done to its World Endurance Championship-winning racer, but we're already looking forward to this year's Le Mans. It's going to be cracking. You'll find a press release below the videos with more info on the Audi.

In the FIA World Endurance Championship (WEC) and in the Le Mans 24 Hours as the season's pinnacle event, Audi is going to compete with a hybrid sports car in the 4-megajoule class. A twofold quantity of hybrid energy, fundamentally revised aerodynamics, the next step in lightweight design and a lot of detailed work characterize the fifth generation of the Audi R18. "The possibilities of the revolutionary regulations that have been in effect for LMP sports cars since 2014 are far from having been fully used.

Automakers paying Chinese dealers for lower-than-expected sales

The Chinese dealers vs. foreign manufacturers story won't quit. It began with a story on the struggles faced by FAW-Toyota joint venture dealers, with supposedly 95 percent of the showrooms losing money, and 10 percent of them doing so poorly that they'd have to exit the business. The problem is mandated sales targets, most set when the country's economy was racing. Now that things have slowed, China's dealers are swimming in unsold cars and the costs to keep them. In the case of FAW-Toyota, dealers asked Toyota to hand over 2.2 billion yuan ($355 million) to help address the situation. That was followed by a report noting the issues that Honda, BMW, and Nissan dealers are having with the same issue, revealing that the Chinese Automobile Dealers Association (CADA) had taken the highly unusual step of writing to the Chinese government to complain. Now Reuters reports that CADA is not only pressing its case even harder, it's being open about it: it announced that BMW agreed to pay dealers 5.1 billion yuan ($820 million) to alleviate poor profits last year. Unnamed sources said Audi has thrown 2 billion yuan into the kitty for subsidies, and Daimler has contributed "about 1 billion yuan" to its dealers. The battle isn't just about 2014, but how business will be run in 2015 as well: Chinese Porsche dealers have requested the automaker lower its 2015 target of 64,000 cars, which would be a 40-percent increase on its 2014 sales of 46,931 vehicles. One analyst called it "shocking" that the CADA has taken its fight public, while CADA comments continue to imply that dealers have been railroaded to the cliff's edge without recourse. "Due to the difference in status," it's deputy secretary said, "individual dealers are not willing to, or don't dare to, talk frankly with the carmakers...." Both parties need one another, so they'll figure out a way to make it work – but that could mean acknowledging the Chinese market is behaving more like a mature one, not an emerging one.
