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 X4 tunes up its crossover game in Germany

Except for the fancy wheels and the overly expressive fascias, the production version of the BMW X4 looks like it will carry over practically untouched from what we saw in the X4 Concept several months back. With the same fastback roofline as the concept, these spy shots show that the X4 is taking shape to be a baby version of the BMW X6.
Sharing the same platform as the X3, the lower and wider X4 will be positioned slightly more upmarket - as is the case with the X5 and X6. We hear that this could mean that the X4 will ditch the X3's base engine to give an even sportier feel right out of the gate, but word has it that an M version will being showing up down the road as well.
BMW has already revealed what it plans to show off at the Frankfurt Motor Show (i3, 4 Series Coupe, next-gen X5, refreshed 5 Series, X5 Concept eDrive plug-in hybrid and Concept Active Tourer Outdoor), so barring any surprised we definitely won't be seeing the X4 there. At this point, with as close to production as these images would have us believe, our best guess would be that we'll see the X4's official unveiling happen either at LA or Detroit.

BMW i3 Shadow Sport limited edition opens a moon roof on US

Here's a bit of news for a quarter-million dollars. BMW is bringing a special edition i3 called Shadow Sport to the US for the 2016 model year. That tag refers to the special-edition Bimmers that come equipped with a moon roof, which before this was unavailable in the US. But only 50 lucky folks will get them. The Shadow Sport edition comes with a few other goodies, too, including "fluid" black paint, 19-inch alloy wheels, custom-trim interior and sport-tuned suspension, though there are no changes in the electric motor or performance. That means the same single-charge range of 81 miles, the same 0-60 miles per hour acceleration time of seven seconds flat and the same top speed of 93 miles per hour. If you experience a little slower speed and a little shorter single-charge range because you're spending too much time looking out of the moon roof, that's on you. The catch is that the model won't be available for the i3 vehicles with the gas-powered range extender, i.e. the i3 REx. The Shadow Sport will also have a price of $47,400, or $5,000 more than the base model i3. BMW's Dave Buchko told AutoblogGreen that all 50 Shadow Sports have been sold, with the first 40 selling out in the first hour or so of availability. The Shadow Sport is on display at the Los Angeles Auto Show this week. Through the first 10 months of the year, BMW sold 8,879 i3 vehicles, which was double year-earlier figures. Last month alone, though, things weren't as rosy, as October i3 sales declined 15 percent from a year earlier to 986 units. There's more information at the bottom of BMW's LA Show press release, below.
