Tesla, BMW and Nissan meeting in secret to discuss charging tech

It's interesting what's happening in the electric vehicle field. It used to be that BMW and Tesla were competitors. Then – and of course they're still competing, especially in the public mind – they were working together on ... something. Maybe. And now, the Financial Times reports that the two luxury automakers are meeting with Nissan. Again, maybe. The scuttlebutt is that the three companies are interested in working together on something to do with charging electric vehicles, potentially a global recharging standard. Currently, when it comes to fast charging, BMW uses the SAE Combo standard, Nissan uses CHAdeMO and Tesla uses its own Superchargers. The meeting was prompted by Tesla opening of all of its patents the other day, FT says. Speaking during the recent annual shareholder meeting, Musk said he was "more than happy to have other manufacturers" use Tesla's Superchargers but that, "there is no other electric car that can accept anything close to 135 kilowatts." Let's assume the technical hurdle can be overcome. With any potential patent/licensing problems out of the way, these discussions with BMW and Nissan might be revolving around this other angle that Musk mentioned: "They (other automakers) just have to contribute to the capital cost, so figure out what percentage of the time are their cars using the Supercharger network and then they can make a contribution proportionate to their customer usage of the Supercharger network." That certainly sounds like something that could take some time to figure out.

2015 BMW 228i Convertible

BMW history is littered with small, four-seater convertibles that offer style, spirited performance and driving flexibility. These days it's the 2 Series range, not the 1 or the 3, that carries on the droptop-driver's-car tradition, and the 2015 228i Convertible will the first flavor of it to hit US shores. With prices starting in the upper $30k range, conservative but attractive exterior styling and just enough interior comforts and amenities to feel like a true-luxury player, the 228i makes a strong initial case for itself as either a first or second vehicle. Concurrent with my First Drive of the 2015 BMW X6 M, the Germans brought along their new 2 for testing along some pretty mellow Texas driving routes outside of Austin. With roads that ranged from sweeping country lanes to small town streets, and weather changing handily from cold and misty to bright and warm, I got a good sample of what the new open-top 2 can do. Drive Notes I'll admit to getting behind the wheel of the 228i convertible with a bit of a bias: the old 1 Series line, including the droptop, was amongst my favorite BMW models in years. In terms of overall character, this 2 Series has mellowed a lot versus the chuckable, cheerful 1er. The steering response isn't quite so whip-fast, and the longer wheelbase means it's less willing to rotate overall. Of course, the 2, especially in convertible form, does feel better suited for the stereotypical small, premium convertible driver, too. Ride quality over our mostly smooth-road drive route was placid and controlled, and steering still felt steady and weighty on center and with lock added in. The car also offers really well-sorted protection from wind buffeting and noise, both with the top raised and lowered. I drove topless on the highway and on surface streets, and was impressed at how cozy I felt with the wind deflector erected and the windows up. Cold-weather convertiblers should do well with this BMW (especially when the xDrive AWD car launches, later in the year). Erect the folding soft top – a feature that's available at speeds up to 30 miles per hour – and the NVH experience is transformed. BMW says that the top-up wind noise has been reduced "by half" versus the 1 Series – a fact that I had no trouble believing after the first few seconds. Wind rush is basically eliminated with the roof raised, and the car becomes a downright conversational space thusly set up.

BMW M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.
