BMW 1 Series prototype packs direct water injection

Just a few months ago, BMW showcased an M4 that was modified to serve as the safety car for the MotoGP racing series. The flashing lights and emergency equipment, however, weren't the only modifications BMW made to the performance coupe. It also packed an innovative new water injection system. And now it's furthering the development of that system by running it in a 1 Series hatchback as well. Revealed at the BMW Group Innovation Days 2015 event, this five-door 1 Series packs a three-cylinder gasoline engine – like the one found in a Mini or i8 – but fitted with the direct water injection system. In this application, the system sprays a fine mist of water – yep, regular old H2O – right into the combustion chamber. While mixing water with gasoline normally wouldn't be recommended, in this case it evaporates immediately and helps cool the engine from the inside, allowing it to run at higher efficiency. That cooler running engine brings with it several benefits. It delivers improved fuel economy and lower emissions, to start. It also allows for an earlier ignition point, higher compression ratio, and higher boost pressure in turbocharged engines, delivering increased output. It even cuts down on engine knocking (where combustion occurs spontaneously), reduces wear and tear on the engine, and makes better use of lower octane levels. If that sounds like a win-win-win... win (we're losing count of all the wins here), it's because BMW just may be on to something. Of course it does require a water tank to be fitted on board, which means added weight, but instead of requiring the driver fill up the water tank, BMW has fitted this prototype with a system that replenishes the water level from the air conditioning system when the vehicle is switched off. So unless it's being driven in a particularly extreme climate, it doesn't even need topping up. Add one more "win" to the list, then. Extra power, improved real-world fuel economy: Direct water injection enhances efficiency. With direct water injection for turbocharged petrol engines, the BMW Group has again succeeded in enhancing the capabilities of conventional engine technology through an ongoing process of refinement and improvement. The precisely controlled injection of water into the engine cylinders produces a cooling effect that boosts power and torque, particularly when operating at or near full throttle, while at the same time reducing fuel consumption and emissions.

2015 BMW X6 keeps it weird

Say what you will about the BMW X6 - odd and ugly as it may be, it's actually been sort of successful for the German automaker. BMW has now sold some 250,000 examples of the X6 since its launch, and the company's fastback-crossover-coupe-whatever-thing gets a host of meaningful updates for the 2015 model year while not straying from its original mission.
Aside from its revised styling, most noticeably set apart by its larger, X5-inspired headlamps, the biggest update for the US-spec X6 is the addition of a rear-wheel-drive model, the sDrive35i. This trim joins the all-wheel-drive xDrive35i and xDrive50i, and since you should all be capable of decoding BMW's weird naming structure by now, you know this means the X6 will be offered with a choice of 3.0-liter turbocharged six-cylinder and twin-turbo 4.4-liter V8 engines. Fuel economy figures have not been released yet, but BMW says the new powertrains are more efficient than before, mated exclusively to an eight-speed automatic transmission regardless of cylinder count.
Look for the updated X6 to hit US showrooms this fall, following its debut this week in Paris. Expect pricing to be revealed closer to the model's on-sale date. Have a look below for all of the details.

Recharge Wrap-up: BMW invests in Zirx, EV charging on National Mall

BMW i Ventures has invested in valet company Zirx. Zirx offers on-demand valet services in urban centers and other areas where parking can pose a challenge to drivers. Drivers use the Zirx app to mark their location, where an agent will pick up the car and park it and, if desired, refuel/recharge, wash or have other maintenance performed on the vehicle in the meantime. "BMW i Ventures provides equity financing to service providers it identifies as having high potential to make urban mobility smarter, more efficient and more flexible," says BMW i Ventures Managing Director Ulrich Quay. "With its combination of service and technology that makes it easier for drivers to park and take care of their cars, ZIRX has the potential to be a central component of on-demand services."

While Toyota searches dominate much of the rest of the world, Tesla is enjoying solid favor in Norway. While electric vehicles make up about a quarter of new car sales in the Scandinavian country, Tesla has had trouble getting a foothold in China. Perhaps the Google searches mean Chinese drivers could be warming up to the automaker. Read more from Gas2. Two EV charging stations have been installed at the National Mall in Washington, DC. Installed by the National Park Service, the stations – which cost $2 per hour to use – are located across from the National Museum of American History and from the National Air and Space Museum. "As the National Park Service prepares for its second century of service to the American people, we are committed to providing clean and green energy to promote a healthy environment," says the National Park Service Acting Superintendent Karen Cucurullo.
