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 i5 could be a new kind of i PHEV

Just this month BMW North America CEO Ludwig Willisch made a point of saying "Not any time soon" to AutoblogGreen's question about the arrival of a BMW i5 - and that came after he clarified, in case we didn't know it, that no such model exists. But the rumors of its eventual appearance were swelled again by a report in Autobild that sticks more details and numbers on what could be the next offering in for the i brand. In February, Car magazine laid the i5 out as having a 245-horsepower four-cylinder engine in front, assisted by a 204-hp e-motor in the bow and a 90-hp e-motor in the stern, for about 544 total horsepower. Autobild claims the gas engine will have 218 hp, the front e-motor will have 150 hp and the rear will have 272 hp, for roughly 640 total horsepower. Where the two reports agree is that it - maybe called i5, maybe i7 - will be based on the China-market long-wheelbase 5 Series platform, it will incorporate cues from both the 7 Series and 6 Series Gran Coupe, and it will not be cheap: 100,000 euros ($105,686 US) is the estimate. The i8 starts at 130,000 euros in Germany. Weight for the i5 is figured to be around 3,300 pounds. Green Car Reports says what's important about the i5's drivetrain is that it's being maximized for electric running. Its evolution of the company's eDrive mechanicals will crank the ICE over only above 36 miles per hour, and even then, only in cases of "maximum power demand." Electric-only driving would offer a range of 78 miles, company officials suggesting that it could remain in that mode for "fully two-thirds of its usage cycle." Whenever a vehicle like this arrives, that is, which Autobild says could be in 2019.

Behind the Scenes of BMW's 'Drift Mob,' Part 2 [w/video]

After spending four days practicing about a dozen drift stunt moves in a parking lot for an upcoming BMW "Drift Mob" internet mini-film, Rhys Millen, Sam Hübinette, Dai Yoshihara, Rich Rutherford, and Conrad Grunewald are finally ready for show time. We are brought to the huge urban traffic circle to see the stunts performed midway through the day to observe for a couple of hours.
The undertaking is massive, with multiple cameras set up, scores of crew members, a helicopter filming from above, a rigged pickup for car-to-car shots, sidewalks lined with security and plenty of curious onlookers, and oh, yeah, a major intersection of a top world city shut down for an entire weekend.
The five drifting legends are nestled in their identical red BMW M235i coupes, which have been modified with special handbrakes but essentially nothing else you can't get on a stock version, and are listening to direction from director Mic Rodgers and stunt coordinator Riley Harper. We're basically given free rein of the set, to shoot the cars, the drivers, and at one point, even hopping in with Yoshihara for one of the admittedly more tame stunts. Even then, the g-forces are so severe that they flip our cameraphone's video recording from landscape mode to portrait. Yes, this is a pretty cool day to be reporting on cars, and as we said during our first installment of our behind the scenes coverage of Drift Mob, we're honored to be the only US media outlet here to tell the tale.
