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.

BMW chooses Tesla's Supercharger network for its future EVs

BMW, following the lead of many other automakers, has confirmed this week that it will adopt the North American Charging Standard (NACS), delivering EV drivers in the U.S. and Canada access to Tesla’s Supercharger network. The move goes a step further in cementing NACS as the universal system of choice. The conversion to Tesla plugs will begin formally in 2025 for BMW, as well as its Mini and Rolls-Royce brands in the U.S. market. Those marques now use the Combined Charging System (CCS) for EV charging. “It is our top priority to ensure that our drivers have easy access to reliable, fast charging," said Sebastian Mackensen, President & CEO, BMW of North America. NACS, which began as began as TeslaÂ’s proprietary charging connection, rapidly has become the new standard in its native land after Ford announced it would adopt it this past summer. This was quickly followed by General Motors. Since then, brands including Rivian, Mercedes-Benz, Volvo, Nissan, Polestar, and Jaguar have climbed d on board NACS. Earlier this month, the Hyundai Motor Group announced it would also provide customers with the NACS connector across its namesake, Kia, and Genesis marques. BMW says it will work across its three marques in the coming months to ensure a smooth transition to TeslaÂ’s charging network by early 2025, and owners will be able to pay for charging using their respective vehicle brandÂ’s own app. Related Video: How to charge a non-Tesla on a Supercharger

Check out the trick way you access the tire valve on this BMW Alpina B6

The wheels are one of the first things you notice when checking out the 2015 BMW Alpina B6 xDrive Gran Coupe. The 20-inch aluminum alloy rollers have 21 spokes that spray out from their hubs, creating one of Alpina's signature design features. But there's also plenty of function to go along with the stylistic form of this hotted-up BMW 6 Series Gran Coupe.
By rotating the Alpina roundel and unlocking the center hub, you gain access to the tire valve and bolts, which are hidden inside. They're literally kept under lock and key, and they protect your Alpina's wheels from the elements and theft. This unique center-fill system employing a hollow spoke isn't a new setup for the favored BMW tuner, but since Autoblog had one in our offices this week, we thought we'd take the opportunity to show the unique mechanism in case you haven't seen it before. Check it out in our brief video below.
