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.

Recharge Wrap-up: Grimsel electric car breaks acceleration world record, electric Ford Raptor ATV debuts

An all-electric version of the Ford F-150 SVT Raptor is now available... as an ATV. Made by Caddyshack Golf Cars, it features officially licensed Ford badging borrowed from the super-macho pickup. It has a lifted chassis with leaf springs in the front and rear, hydraulic shocks and off-road tires. Powered by a 48-volt motor, it can do 0-25 mph in 2.9 seconds. Range is an estimated 30 miles - plenty to get you through 18 of the most rugged holes of golf you've ever played. Caddyshack also offers other miniature electric Fords, including a Shelby GT500, Shelby Cobra and 50th Anniversary Mustang. Read more at Green Car Reports. Lexus takes a crack at the BMW i3 in a new video from Funny or Die. In the decidedly anti-EV film, a group of guys drives to Las Vegas for a "dad-chelor party" in a Lexus CT 200h and a BMW i3. The Lexus hybrid makes it to Sin City without any problems, while the BMW's occupants need to make several lengthy stops to charge along the way, missing much of the fun. The video lampoons the inherent range limitations of the EV (the BMW group ends up driving slowly through the desert with no AC or radio to save energy), all in a well produced, if somewhat misguided, short comedy film. Perhaps they should have considered the i3 with a range extender? See the video below, or read more at Green Car Reports. Students from ETH Zurich and Lucerne University have set a new EV acceleration world record. Their "Grimsel" racing car was able to zoom from 0-100 kph (0-62.137 mph) in just 1.785 seconds in less than 30 meters (98.425 feet), crushing the previous record of 2.134 seconds. Even more impressive is that the Grimsel was built by the students themselves, as part of the Formula Student team at the Academic Motorsports Club Zurich. The car weighs just 370 pounds and provides 200 horsepower and 1,202 pound feet of torque from the four hub motors. The Grimsel uses traction control to manage torque for maximum acceleration. See the record acceleration run in the videos below or read more at Gizmag, at Electric Autosport or in the press release from ETH Zurich below. 'grimsel' breaks world record The 'grimsel' electric racing car today broke the previous world record for acceleration in electric cars. The vehicle accelerated from 0 to 100 km/h in 1.785 seconds in under 30 metres. The new record was set by students from ETH Zurich and Lucerne University of Applied Sciences and Arts, who also designed and built the vehicle.

BMW X4 opens up alongside its boxier brother

It doesn't seem so long ago that BMW (not to mention Audi, Volvo and a handful of other European automakers) weren't in the crossover market. But it's been over a decade since BMW began producing the first-gen X5, and in the fourteen years since, the Bavarian automaker has steadily expanded its portfolio to include the X1, X3 and X6.
The next to join the family will be the X4, which is essentially to the X3 what the X6 is to the X5. That is to say, basically the same vehicle, only with an (arguably) more stylish but less utile roofline. Previewed in concept form at the Shanghai Auto Show half a year ago, the X4 has been snapped by our plucky paparazzi in the past, but this is the first time we've seen inside.
Not only that, but the prototype in question was spotted next to the current X3 on which it is based, which gives us ample opportunity to see the differences between them. Of course, that still primarily comes down to the slantback profile, because otherwise, the two are essentially the same inside and out. Or at least they will be: many of the differences between the two are expected to port over to the X3 when it's refreshed next year, including some subtle interior upgrades - just not the roofline.
