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.

Next BMW X1 caught on flatbed

The X1 had been around for four years before it was added to BMW's US lineup, so it isn't all that surprising that a new version of the company's smallest Sport Activity Vehicle is already in the works. Captured in transit on the back of a flatbed truck, these spy shots give us our first look at the next-gen X1 - codenamed F48 - which is expected to debut around 2015.
While the camouflage does a good job of obscuring most of the styling elements, we definitely see evidence of the X1's new platform. Elements like the loss of the long nose and a noticeably shrunken dash-axle gap (just compare this spy shot picture to this one from our X1 review), are good indicators that the next X1 will move to the new front-wheel-drive platform BMW is using for the new Mini and 1 Series GT. Aside from this, the overall shape is very similar to the current design, but we're sure it will pull many cues from the updated range of BMW products.

BMW revisits its 8 Series

So why would BMW choose July 2 to release a retrospective on the 8 Series? Could it have something to do with the recent unveiling of the Pininfarina Gran Lusso Coupe concept, another sleek, B-pillarless V12 two-door, at this year's Villa d'Este? We have no idea, but the timing is likely coincidental.
This three-minute look at the 8 Series talks to Niels Hamann, who was smitten with the long-hooded coupe when it appeared in 1989 and finally bought one in 2004. Hamann also happens to be a project manager at BMW, and that came in handy when he wrote a book detailing every aspect of what was BMW's flagship for ten years but to the chagrin of many only managed one generation.
While we wait for the next clue about the Gran Lusso - 8 Series connection, check out the video below.
