Audi and Mercedes both outsell BMW in January

There won't be any celebrations in Munich this month, as BMW was outsold by arch-nemeses Audi and Mercedes-Benz. The Bavarian company finished behind Audi in January, which took the top spot for the first time since June of last year, Bloomberg reports. Ingolstadt rode high on a 10-percent bump in sales, while Mercedes saw a larger 14 percent increase. BMW, meanwhile, only saw a modest 6.3-percent sales increase last month, thanks in large part to its struggles in China. The company's sales there increased at about half the rate of its chief competitors, with a 7.9-percent jump to Mercedes and Audi's roughly 15-percent increases. Perhaps more worrying for BMW, though, is that this could become something of a trend for the company. According to Bloomberg, issues with Chinese dealers who cancelled orders over sales targets and bonuses combined with what the publication calls aging models, could spell bad news for the German marque. "This looks like a pretty significant decline in growth compared to Mercedes and Audi," Bankhaus Metzler analyst Juergen Pieper told Bloomberg. "I think this will continue during the next few months." News Source: BloombergImage Credit: Matthias Schrader / AP Earnings/Financials Audi BMW Mercedes-Benz

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago.

Audi boss can't say no to F1 program

Audi has been a dominant force at the top rung of endurance racing for over a decade. Still, rumors have fired up again about the possibility of the company making a big switch to Formula 1. The Four Rings' boss Rupert Stadler isn't ready to make that decision yet, but he's not ruling it out. When asked by Auto Express about the potential of Audi entering F1 in the next five years, Stadler gave an intriguing answer. "It's something we're looking at, but then we're always looking at it and many other things. But I can't say yes or no," he said. While not at all a confirmation, that's hardly an outright denial, either. According to unnamed insiders speaking to Auto Express, Audi is under pressure from Volkswagen Group to leave the FIA World Endurance Championship. Right now, the Four Rings is competing directly against its corporate sibling Porsche. While that might make for a good rivalry on the track, it doesn't necessarily make sense financially. Rumors last year suggested that Audi might leave the WEC and DTM to finance the F1 project. Two possibilities were proposed at the time: act as engine supplier to Red Bull or buy Toro Rosso to run a whole new team. Stadler's non-denial might also indicate that Audi's view on F1 is shifting. In the past, the company's opinion has been much more obvious. Last year, Audi Sport tweeted that the rumormongering was "pure speculation." As far back as 2011, the brand's motorsport boss said grand prix racing had "no relevance to the road." Related Video:
