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 4 Series Gran Coupe spotted wearing minimal camo, M Sport pack

The new BMW 4 Series is essentially the coupe version of the latest 3 Series. So it would stand to reason that the four-door version of the 4 Series, in turn, would be the 3 Series - right? Well, yes and no.
Just as BMW offers both a 5 Series sedan and a four-door version of the 6 Series called the Gran Coupe, so, too, will its 4-Series family expand. So following the release of the new 4 Series Convertible, here we have the latest batch of spy shots showing the upcoming 4 Series Gran Coupe - which in turn should not be confused with the hunchbacked 3 Series Gran Turismo, which is more of a sporty wagon than a four-door coupe.
The nearly ready test vehicle pictured here is wearing only minimal camouflage to hide some last few details, but also appears to be wearing the M Sport package that will bridge the gap (at least, visually speaking) between the base models and the M4 Gran Coupe that is all but certain to follow.

BMW seeks partners for electric Mini, could make it an all-EV brand

LOS ANGELES — Germany's BMW is talking with other automakers "around the world" to try to find partners to lower the cost of electrifying its future Mini small cars, management board member Peter Schwarzenbauer told Reuters. "We are talking to many OEMs (manufacturers) around the world, not only in China, (about) how to electrify smaller cars," Schwarzenbauer said. "There's no final conclusion on it." Chinese automaker Great Wall Motor said last month it was discussing a possible venture to build Mini vehicles in China. BMW currently does not build Mini vehicles outside Europe. Schwarzenbauer declined to discuss the Great Wall situation, saying "this was speculation." However, he said building smaller electric cars was challenging, not only because of the financial costs, but also the engineering problem of fitting batteries with sufficient range into a smaller vehicle package. BMW has worked with rivals before to share the costs of clean vehicle technology. The automaker has a partnership with Toyota to develop fuel cell vehicles. BMW has said it plans to launch a new, electric Mini model in 2019. Eventually, Mini could become an entirely electric brand aimed at urban consumers, Schwarzenbauer said. Mini sales in the United States have fallen 10 percent through the first 10 months of this year, as demand for many smaller cars has waned in favor of sport-utility vehicles and trucks. "It's really only in the U.S. where we are facing this with Mini," Schwarzenbauer said. BMW will not try to reverse that trend by adding larger SUVs to the Mini lineup, Schwarzenbauer said. Instead, he said, "the way for Mini in the U.S. is ... building the Mini brand in the direction of the electric urban mobility company." On a separate issue, Schwarzenbauer said BMW intended to offer a self-driving car planned to debut in 2021 at a price that could be below $100,000. The iNEXT model, which BMW previewed earlier this year, will be offered to individuals, ride services fleets and put into service in BMW fleets, Schwarzenbauer said. "By 2021, you will have a lot of people who want to own this car," he said. "It will be a normal price. We are thinking of scaling this. To bring a $150,000 electric car is nice, but it will not really scale." When it launches, the iNEXT may not be offered with complete, so-called Level 5, autonomy because the regulatory and legal frameworks for such a vehicle likely won't be in place, Schwarzenbauer said.
