What does the open patents deal mean for Tesla ... and BMW?

Gift to the world or trade bait? Tesla Motors announced this week it would open its patents for other automakers to use. That has analysts guessing whether the California-based electric-vehicle maker is looking to either swap trade secrets with other automakers or to expand the proverbial pie that represents the plug-in vehicle market. For its part, Tesla says the answer is B. BMW, which is establishing its i sub-brand of plug-in vehicles, would be a natural collaborator with Tesla, Forbes says. In fact, executives from the two companies met in Europe this week. Details were not released, but a BMW spokesman said, "Both companies are strongly committed to the success of electromobility and discussed how to further strengthen the development of electromobility on an international level." While Tesla brings battery technology to the table, BMW offers its carbon-fiber advancements that lighten vehicle-body weight. Those advancements are key to range-extending efforts and could do wonders for Tesla on its journey to help spur technology for the sake of getting more of the general public to accept plug-in technology as a viable first-car option. Then again, Forbes says Tesla, whose investors include Mercedes-Benz parent Daimler and Toyota, may be keeping its best technologies to itself by not patenting certain advancements at all. What's in Tesla's patent pool? uAutoInsurance analyzed Tesla's 249 patents and found that 104 of them related to battery technology, while 28 pertained to recharging activity, which wasn't surprising (about a quarter of those 249 patents couldn't readily be categorized). Tesla also has nine patents related to sunroof technology. The company is based in California, after all.

BMW preparing two concepts for Villa d'Este

Every spring, the finest automobiles ever to grace tarmac gather on the shores of Lake Como for the Concorso d'Eleganza Villa d'Este. It's a chance for the most beautiful classics to compete for awards and for automakers and design studios to show off their concept cars under the soft light of the Italian sun. But while most of the vehicles old and new that show up for the concours are ones we've seen before, BMW takes things a step further.
As patron of the concorso d'eleganza for the past ten years, BMW regularly cooks up something new for the glamorous extravaganza. Last year it teamed up with Pininfarina for the Gran Lusso Coupé and revealed it alongside the Concept 90 motorcycle. The year before that came the BMW Zagato Coupe, preceded by the 328 Hommage and the M1 Hommage (pictured above) before it.
The theme for this year's event is the Roaring Twenties. BMW may not have been known back then on the same level as Bugatti or Duesenberg, but Rolls-Royce sure was.

History of BMW touring cars looks splendid in Adrenalin trailer

More high-quality documentaries about the history of motorsports are always welcome. When thinking about racing, we generally focus on moving forward to go a little faster or shave a tenth of a second off a lap. There's not much time to look backward. It's too bad, because there are so many fantastic stories from the sport's history. Thankfully, an upcoming doc is taking on the challenge of telling some of these tales, and it looks like a movie not to miss, especially for BMW fans.
Adrenalin - The BMW Touring Car Story mixes high-quality, vintage footage with new interviews from many of the drivers of these machines to craft what looks like a fantastic experience. Covering the period from the '60s to the modern DTM era, just the trailer shows racing from the 2002, 3.0 CSL and of course the E30 chassis M3 of the '80s. You also get to hear from legends behind the wheel like Hans-Joachim Stuck, Johnny Cecotto and Joachim Winkelhock telling their stories.
Adrenalin comes out in November on DVD, Blu-Ray and on-demand. Check out its trailer above for a taste at what it's aiming for. The documentary definitely looks like one to watch.
