Mercedes could make EV batteries with Audi, BMW

It's not a big leap from digital maps to batteries, it turns out.The head of Mercedes-Benz parent Daimler said recently that he envisions his company working together with German automotive competitors BMW and Volkswagen to further accelerate electric-vehicle battery technology. The three automakers recently worked together to enhance their in-car maps systems. Daimler CEO Dieter Zetsche talked about "commonalities" between automakers, not the least of which is the need for all of them to achieve increasingly stringent fuel-economy requirements in the European Union, at the Frankfurt Auto Show last week, according to Reuters. While these companies have made their own inroads as far as plug-in vehicles go, they are all behind the Renault-Nissan Alliance when it comes to public deployment of electric vehicles. This summer, Daimler, Audi and BMW hooked up to acquire the Nokia Here digital-mapping service for about $2.8 billion. The triad of automakers beat out companies such as Apple and Uber to buy the entity, which was founded in 1986 as Navteq. Nokia bought the company in 2007. The acquisition makes sense as the automakers work on improving their products with features like cloud-based data to warn drivers of icy roads and traffic jams. The technology will likely also eventually be used in autonomous vehicles. Automakers working together for a common goal of improved technology is nothing new, of course. General Motors and Honda agreed in 2013 to work together to accelerate hydrogen fuel-cell drivetrain development. Earlier that same year, Daimler said it would work with Ford and Nissan in a separate collaboration to speed up the development of hydrogen fuel-cell technology. Related Video:

Mercedes and VW battling Uber and Apple to spend billions on Nokia mapping division

Whether for autonomous driving or simply better navigation, digital mapping is closely linked with the future of motoring. The sale of a major player in that industry is spurring a showdown between automotive behemoths and tech giants, and it's a fascinating battle to watch unfold. Nokia is selling its Here mapping division, and while the company might not have the name recognition of Google, it controls about 70 percent of the auto market. The business is valued at $785 million, according to Reuters, but is likely to sell for significantly more. Case in point: Uber reportedly submitted a $3 billion bid. Apple has also been rumored to be among those interested in purchasing Here. A trio of German automotive heavyweights is mounting a challenge to Silicon Valley, though. According to Reuters speaking to two unnamed insiders, Daimler, BMW, and Audi are teaming up to submit a joint bid for an undisclosed sum. They're worried that if Here falls under the control of tech companies, then automakers might have limited availability to these vital maps in the future. Nokia bought Here for $8.1 billion in 2007, according to Reuters. The company operates a fleet of vehicles with cameras and LIDAR that drive around the world to create high-definition maps. It also generates even more information by using the GPS data from shipping and trucking companies.

Lewis Hamilton owns 15 cars, uses tow trucks to keep the mileage low

No matter how you feel about Lewis Hamilton off the track, it's impossible not to respect his talent behind the wheel. Currently, Hamilton is the second most successful Formula One driver of all time. His 67 wins and four championships place him only behind Michael Schumacher's 91 wins and seven championships. With all those winnings, Hamilton has racked up a decent personal fortune, much of which he uses to buy cars. Except he doesn't drive them quite as much as you might think. According to The Sunday Times, Hamilton's net worth of just over $207 million makes him one of the richest sports figures in the UK, just behind David Beckham. In a recent interview with the British newspaper, Hamilton gave some details on his personal car collection. His first car was a used Mini Cooper, soon followed by a Mercedes-Benz C200. Both have long since been replaced by a pair of original Shelby Cobras, a 1967 Shelby GT500, a Ferrari 599 SA Aperta, two LaFerraris (a red coupe and a white Aperta), a McLaren P1 and a Pagani Zonda 760 equipped with a manual transmission. All in, Hamilton has about 15 cars split between homes in Monaco and Los Angeles. Unsurprisingly, he has a Mercedes-AMG Project One ( a car that shares more than a little with his F1 W09 EQ Power+ race car) on the way. Hamilton has some hot takes on his personal collection. "The Zonda is terrible to drive," he said. "It's the best-sounding car I own, but handling-wise it's the worst. I got it in manual because I didn't like the tiptronic version. The tiptronic Pagani offered was worse than the Smart Roadster I had." He also says his Shelby Mustang is a "beautiful car, but a heap of junk." In order to keep the miles down (and valuations up), Hamilton apparently has a tow truck on retainer in Los Angeles. When he's finished driving one of his Ferraris, he'll have the car towed back to his place. Classic cars are becoming a solid and serious investment, and Hamilton doesn't want to squander his wealth like some other athletes. That said, there are a couple more cars Hamilton would love to own, including a Mercedes-Benz 300 SL (the one with the gullwing doors) and a Ferrari 250GT California Spyder (the one from "Ferris Bueller's Day Off").
