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 apparently still undecided about future i project electric vehicles

Coaches like to say that there's no "i" in team. At least one BMW executive is saying the company's not sure if there are any more "i"s in its near future. BMW executive Harald Krueger indicated that the German automaker is holding back on any i-project plans besides the i3 city car and i8 plug-in hybrid sports car until the company gets a better idea of how those models are selling, Reuters says. Bimmer has spent about $2.7 billion on the plug-in sub-brand and says it's taken more than 11,000 orders for the i3 since the model was first shown off at German dealerships last fall. Additionally, BMW has no plans to make the i3 in China (BMW makes versions of its 3- and 5-series sedans there). As we all know, should the brand expand, BMW has already trademarked the "i" badge from i1 through i9. There are a lot of mixed messages on the BMW i project front. For example, early indications are that i3 demand has been higher expected. BMW North America chief Ludwig Willisch indicated earlier this month that US demand for the electric city car, at least for the near future, will likely to outstrip supply. Bimmer dealers in the US will start getting the $41,350 i3 in May. Additionally, fellow BMW executive Jacob Harb said the company was already starting to work on its next EV, to be larger than the i3, though he didn't give many details and was later somewhat refuted by another BMW spokesman.

Tesla only 8th greenest automaker, BMW is best, says Newsweek

We imagine some readers will be surprised by this. Newsweek has just put out its rankings for the top "green" companies in the world, and while Tesla Motors chief Elon Musk can crow about how green his electric vehicles are, the company as a whole apparently falls behind some traditional automakers. Quite a few of them, actually. In Newsweek's Global 500 list of the greenest 500 largest publicly-traded companies in the world, BMW ranked best among automakers at Number 26. Not surprisingly, Toyota was close behind at 35, while Nissan came in at 152. What's a little more puzzling is that Tesla fell behind Ford (178), and General Motors (289). That's a lot of pickups versus a few Model S EVs. Go figure. Then came Hyundai (306) and Honda (316), which are a little more palatable. Tesla? It came in at 431. Newsweek's measurement standards include eight categories that include a lot of verbiage and involve things like energy productivity (which is defined as revenue in US dollars divided by total energy consumption), greenhouse-gas emissions productivity (revenue divided by GHG emissions), water usage, waste levels and something called "green revenue" (revenue derived from products that "contribute positively" to the environment). Newsweek says that its results are reproducable by a third party. Take a look at the list here and find the details on how the numbers are compiled here.
