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:

2015 BMW M3 Sedan, M4 Coupe are officially revealed [w/video]

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.

BMW considering M7 and luxurious 9 Series

BMW just recently rolled out its new flagship 7 Series sedan. It didn't take long for it to introduce not one, but two performance versions as well. But what we've seen until now could only be the start as the Bavarian automaker looks to close the gap between the 7 and the Rolls-Royce Ghost. What you're looking at above appears to be a prototype testing components for a potentially forthcoming M7 – which is something that BMW has never offered before. It's packing what look like enormous, cross-drilled brakes – just the kind of thing an M-fettled 7 would need to keep its mass and momentum in check. It was seen running around with an M5 and X6 M, suggesting that it's the performance division that's playing around with this big sedan for the first time. An M7 would have to pack some serious punch, considering what's already on offer. Both the Alpina B7 (4.4-liter V8) and M760Li (6.6-liter V12) each offer 600 twin-turbocharged horsepower and 590 pound-feet of torque driving to all four wheels, capable of hitting 60 mph in the threes. The full M version, then, might need a good 650 hp or more, which would put it out in front of everything else – including the Audi S8 Plus (605 hp) and Mercedes-AMG S65 (621 hp). Even with all that performance and clout, however, the M7 might still not be enough for BMW to close that $200k gap to the bottom of the Rolls-Royce range. That's why it could roll out an even more luxurious and completely separate model, potentially called the 9 Series. The new uber-luxe sedan would take on the Mercedes-Maybach S600 that's proven particularly popular in China, where Automotive News notes that Benz sells half of all the S-Class models it makes. Since they're mostly chauffeur-driven through crowded streets, upscale customers there care less about BMW's traditional focus on handling dynamics and more about comfort. And with the government cracking down on corruption, they've also reportedly been eschewing overt symbols of wealth – like the Spirit of Ecstasy hood ornament, for example. We could expect the 9 Series, then, to offer even more rear-seat legroom than the 7, and be more oriented towards comfort than performance. Related Video:
