How to charge up your BMW i3 with a Honda

Behold a cheaper version of BMW's range extender for its i3 plug-in. And it's brought to you by ... Honda? Sort of, if you take the approach that Gadget Review took when it looked for an alternative to ponying up the $4,000 or so for the gas-powered i3 range extender that comes from the factory. What was procured was a Honda portable generator for Home Depot for the experiment, which involved gassing the generator up in a parking lot, plugging in the i3 and going out for a cup of coffee. The result was that, after about a half-hour of charging, the i3 picked up about four miles of driving range. Not exactly revolutionary but it least a bit instructive. And given that Honda generators start at about $800, the idea, while clunky, is potentially cash-saving. Gadget Review briefly took the experiment one-step further by trying to run the generator inside the back of the car and plugging in, complete with a rigged-up ventilation system, but the host thought better of it once he realized that there'd be suffocation involved. Why this was never tried on the Nissan Leaf, we'll never know. Check out Gadget Review's five-minute video below.

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 warns profits will fall, plans $13.6 billion in cost-cutting

FRANKFURT, Germany — BMW said Wednesday that profits in 2019 will be "well below" last year's, and it will cut 12 billion euros ($13.6 billion) in costs by the end of 2022 to offset spending on new technology. The company said profits would be eroded by higher raw materials prices, the costs of compliance with tougher emissions requirements and unfavorable shifts in currency exchange rates. The Munich-based automaker also faces increased uncertainty due to international trade conflicts that could lead to higher tariffs. "Depending on how conditions develop, our guidance may be subject to additional risks; in particular, the risk of a no-deal Brexit and ongoing developments in international trade policy," said Chief Financial Officer Nicolas Peter. The company forecast a profit margin of 6 to 8 percent for its automotive business, short of the long-term strategic target of 8 to 10 percent, which it said still "remains the ambition" for the company if given "a stable business environment." BMW said it had no plans for layoffs even as it outlined cost saving measures that include dropping half of its engine variants as it seeks to reduce product complexity. The BMW, Mini and Rolls-Royce brands are to get a single sales division. Peter said that given the headwinds to earnings, "we began to introduce countermeasures at an early stage and have taken a number of far-reaching decisions." The company said the measures were needed "to offset the ongoing high level of upfront expenditure required to embrace the mobility of the future." Automakers around the world have faced heavy up-front costs for technology expected to change how people get from one place to another in the next decade. Those include electric cars and renting cars through smartphone apps. Yet the returns from such investments remain uncertain and auto companies face competition from tech firms such as Uber and Waymo. BMW made 7.2 billion euros ($8.2 billion) in net profit last year, down 17 percent from 2017, when it booked a gain of $1 billion from U.S. tax changes. The company faced headwinds from increased tariffs on vehicles exported to China from the United States. It also suffered from turmoil on the German auto market when companies faced bottlenecks getting cars certified for new emissions rules. BMW faces uncertainty from U.S.-China trade tensions that could result in new tariffs if talks do not result in an agreement. U.S.
