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 i8 fully revealed ahead of Frankfurt debut

It may be early in the morning here in the US, but in Germany, the first day of the 2013 Frankfurt Motor Show is in full swing. BMW took advantage of the early start and showed off its long-awaited i8 plug-in hybrid sportscar, a two-plus-two, swan-wing-doored coupe, to the Frankfurt crowd.
We drove a BMW i8 prototype back in August, so many of the things we're reading today are clarifications on our initial suspicions or speculations. Underhood sits a 1.5-liter, turbocharged, three-cylinder engine. On its own, it churns out a respectable 231 horsepower and 236 pound-feet of torque, which is then channeled to the rear wheels by way of a six-speed automatic transmission. An electric motor, meanwhile, sends 131 hp and 184 lb-ft of torque through a two-speed automatic to the front wheels.
With all-wheel drive at its disposal, the total system power sits at 362 hp and 320 lb-ft of torque, and allows the i8 to scamper to 62 miles per hour in just 4.4 seconds. That excellent performance is offset by an estimated fuel economy figure of 94 miles per gallon, though, making this a fast and efficient vehicle. Charging is impressively fast on the i8, with a full charge coming from a 110-volt outlet in under four hours. A BMW Charging Station will trim the charge time down to 1.5 hours.

M-fographic breaks down the history of BMW performance machinery

Few characters carry the kind of clout among performance enthusiasts as the letter M. For 35 years now, that one letter has adorned over 300,000 BMWs, each tuned to deliver a higher degree of performance than the stock models on which they're based.
The M division has worked up nearly 100 different models over the past third of a century, which can leave even the most expert among Bimmer fanatics bewildered. Fortunately British auto loan service Carfinance247 has commissioned this handy infographic to make sense of it all, and you can check it out below to see what the letter M really stands for.
