Tesla in talks with BMW about batteries, charging collaborations

With Toyota and Daimler no longer holding Tesla shares, the electric vehicle company might be looking for a new partner – possibly a Bavarian one. In a new interview with Germany's Der Spiegel, CEO Elon Musk confirmed that he has had talks with BMW execs about future collaboration. "We are talking about whether we can collaborate in battery technology or charging stations," Musk said in the interview, according to Reuters. However, a Tesla spokesperson has tempered things by saying no formal agreements are in place at the moment. In the same interview, Musk reportedly praised BMW's use of carbon-fiber-reinforced plastic in its i sub-brand offerings, and said he would like to have a battery factory in Germany in the next five or six years. The possibility of technological cooperation between Tesla and BMW has been a hot topic this year. In June, Musk reportedly met with BMW execs, and the two companies were also rumored to have met with Nissan to discuss charging technology. When Daimler sold off its shares, there was talk of it opening the way for possible collaboration between the two automakers, as well.

Next BMW 7 Series interior spotted

The next BMW 7 Series looks to be leading a rather dramatic change of the company's interior styling, judging by this new series of spy photos. In the trio of shots, we can see that the next 7 Series will replace the high-quality plastic buttons of the brand's iDrive, HVAC and secondary audio controls with some very, very pretty aluminum pieces. We can also see what looks like haptic touch controls for some of the HVAC systems. While the 7 Series interior has never been bad, it's lagged notably behind the Audi A8 and new Mercedes-Benz S-Class. This brightwork should be taken as a good sign, then, that BMW is preparing to take the fight to its countrymen. Aside from the handsome new switchgear, the large, wide nav screen looks like a pop-up unit, while it appears to be running a new version of the company's infotainment system. These spy photos also give us our most detailed look at the 7 Series' new laser headlights. According to our spies, these will be an optional extra, while LED headlights will be standard. The high-output lights will flank a wider pair of kidney grilles that our spies claim will give the 7 a sportier look. Changes in back are still camouflaged, although our shooters claim the new lamps will be more angular than the current car's. Expect the next 7 Series to make its debut in the second half of 2015, which could indicate a debut at the Frankfurt Motor Show.

BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.
