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.

2015 BMW M4 Coupe ditches some doors, gains some grunt

If you saw our earlier post about the hot new BMW M3 Sedan and were about to call blasphemy for no coupe version, just settle down, silly. Remember: BMW now badges its two-door 3 Series models with the number four, and thus, meet the 2015 M4 Coupe. Looks hot, right?
So yeah, it's pretty much just the M3 with two less doors, but that doesn't make it any less important - or potent. Power comes from a turbocharged, 3.0-liter inline six-cylinder engine, sending 425 horsepower and 406 pound-feet of torque to the rear wheels via either a six-speed manual or seven-speed dual-clutch transmission. You know, the usual.
Not only is the M4 more powerful than the M3 Coupe it replaces, it's a good deal lighter, too. BMW has managed to cut 176 pounds of weight out of the M4, and that means, with the increased output numbers, that the M4 will scoot to 60 miles per hour in 3.9 seconds with the DCT or 4.1 seconds with the do-it-yourself tranny. Either way, that's not what we'd call slow.

BMW offers M Performance Power Kit for 2012 335i sedan

BMW has let loose a new M Performance Power Kit for its F30-generation 335i and 335i xDrive sedans. Starting at $1,100 for the kit - installation is extra - your car will be fitted with a new ECU and air intake on the functional side and an M Performance engine cover and rocker panel stickers on the decorative side. The Power Kit raises the 3.0-liter inline six-cylinder's horsepower rating from 300 to 320, and on automatic models, torque gets a boost from 300 pound-feet to 332 lb-ft - manual transmission models get a smaller bump to 317 lb-ft.
According to the Bavarian automaker, you'll be able to hear the change in the overrun exhaust note, and 0-60 mile-per-hour times drop by 0.2 seconds. The package is available now at all BMW Centers in the US, and if you get it installed when you purchase the car new, it will get the same four-year, 50,000-mile warranty as the vehicle. Have it done after the fact and the kit will be warranted for two years and unlimited miles. There's a press release below with some more details.
