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 X3 ensnared by diesel emissions probe

Volkswagen may not be the only German automaker ensnared by this whole diesel debacle. The latest reports suggest that BMW could be guilty of the same offense. According to Bloomberg, citing a report from Germany's own Auto Bild magazine, the X3 could be over the European legal limit for emissions. The report suggests that a BMW X3 xDrive20d registered tailpipe emissions more than 11 times the limit under testing by the International Council on Clean Transportation. The council is the same that triggered the investigation into Volkswagen that led to the automaker's admission that it cheated on emissions tests for its diesel vehicles and the subsequent resignation of its chief executive. Volkswagen admitted to installing software that initiates additional emissions controlling measures when it detects that the vehicle is being tested. For its part, however, BMW denies that it has any such similar system in place, noting that many of its vehicles have passed testing by the same organization. Whatever the truth in BMW's case, it may not emerge unscathed. Bloomberg reports that the company's stock fell as much as 9.7 percent – the most it has lost in over four years – amid concerns that it could be implicated in the scandal as well. Shares in rival automaker Daimler also dropped by 5.8 percent. Volkswagen has already lost over $20 billion in market value in the midst of the scandal. The German government and European Union are considering implementing more restrictive standards and more thorough testing on diesel engines in order to prevent this sort of thing from recurring.

BMW i8 could get 300-hp, 2.0L turbo-four

First and foremost, the long-rumored, high-performance BMW i8 will not be called the i8 M. While the lack of an M badge might be a disappointment, it's fair to say the performance of the new model likely won't be. AutoExpress claims BMW is developing a new 2.0-liter, turbocharged, four-cylinder that will take the place of the i8's three-cylinder engine. Offering an even 300 horsepower, up from the current car's 228, total system power would sit around 450 ponies, thanks to the extra cylinder. The electric system won't be fettled with, though. If that still sounds modest, it's because it is – AE's source claims the i8 could handle another 300 hp. BMW would also make a concerted effort to at least maintain the current i8's weight, even with the extra heft of the 2.0-liter turbo to deal with. AutoExpress's source claims that BMW could skip the paint on certain exterior carbon-fiber elements while also offering a more focused, minimalist cabin to save even more weight. According to AE, this new model should arrive as early as 2016, which could result in a debut in Frankfurt this September, Los Angeles in November, or even Detroit, in January.
