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.

Bosch has an advanced self-parking system slated for 2019

Self-driving cars are the future of the auto industry, but there are many years and intermediate steps between now and driverless roads. Bosch made one of those important baby steps earlier this month when it unveiled its Home Zone Park Assist, which takes automated parking to the next level. The system works like this: a driver pulls up to where they'd normally begin to angle into a preferred parking spot. The driver then sets the start point and slowly drives the car into place so the system can learn the route. After the route is entered, the driver can let the car take control by either holding down a button inside the vehicle or on a smartphone app to engage the self-parking program from outside the car. Twelve ultrasonic sensors, a rear-facing stereo video camera, and four radar sensors work together to slot the car safely into or out of a spot perfectly every time. If you don't start in the same place every time that's okay, because the car can deviate from the original start and stop points by up to six and a half feet. The system can track up to 100 meters' worth of complex maneuvers, perfect for anyone tired of backing out of long, curvy, or steep driveways. Bosch says the system will be available in a few years but doesn't mention any specific models. Other companies have similar technologies, but they're not quite as advanced. The National Highway Traffic Safety Administration recently cleared a similar technology called Park Assistant Plus for use in the BMW 7 Series. BMW's technology allows drivers to move the car in and out of parking spaces with the key fob. Tesla's Summon feature allows the Model S and X to come when called up to 10 meters away. But Bosch seems to have pushed the boundaries of what autonomous features on cars can do. Besides superior distance, the really amazing aspect of Bosch's system is that it allows cars to sense obstacles within its path and make the decision whether to proceed with minor course adjustments or stop and wait for its owner. That's right, a decision-making car. Welcome to the brave new world. Related Video:

BMW X4 Concept images leak ahead of Shanghai debut

Last month, BMW confirmed that its long-awaited X4 crossover would debut next year, but other than imagining a smaller X6-shaped crossover, we really had no idea what the new niche model would look like. That is until a Russian website, Autowp, leaked a handful of embargoed images this morning showing the X4 Concept that will be unveiled in a couple of weeks at the Shanghai Motor Show.
From what we can see of this concept's styling, there are more elements shared with current BMW models than not. The face of the concept is an attractive blend of the current 3 Series sedan and the X3, while the roofline has definitely plucked right from the X6. This thinly veiled concept should carry over almost untouched when it enters production with the exception of the door handles and the overly stylized fascias and side mirrors. According to CarScoops, it will measure the same length as the current X3 and use the same engine lineup as well. Stay tuned, as we'll have more information on this concept shortly.
