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 Pininfarina Gran Lusso Coupe and Concept 90 pics from Villa d'Este

Royalty and the ultra-wealthy rubbed damp shoulders at this past weekend's Concorso d'Eleganza Villa d'Este on the shores of Italy's Lake Como, but even the rain couldn't extinguish the excitement generated by the millions of dollars of cars and bikes on display. Nowhere was this more true than with BMW, which marked the occasion with the reveal of two stunning concepts with six wheels between them - the shark-nosed Pininfarina Gran Lusso Coupe and the retrosexual Concept 90 motorcycle.
Conceived with Italian design house Pininfarina, the Gran Lusso Coupe is a power broker on 21-inch wheels. While we're not completely sold on every element of its design, this twelve-cylinder two-door concept moves us more than the current 6 Series, and not just because it has four more cylinders underhood and 48,000-year-old kauri wood paneling inside. BMW is sadly mum on production hopes, but we're not entirely optimistic - the company has graced us with a number of attractive concepts at Villa d'Este before, only to pack them away again without ever affording them a production future.
If one of these concepts has a better shot at finding its way into dealers, we have to believe it's the Concept 90 under the BMW Motorrad umbrella. Designed to celebrate the 40th anniversary of BMW's R 90 S, we think this Roland Sands Design air-cooled boxer would look fantastic on today's streets, especially with the rising popularity of vintage motorcycles and cafe racers.

Reveal of next-gen BMW 7 Series set for June 10

Executive vice presidents of the world, your next sedan is debuting in just a few days. BMW is finally taking the wraps off the next-gen 7 Series on June 10, and the Bavarian brand's teaser video provides a few early hints about the high-class model. Highlighting a 750Li, the camera in the teaser swoops around the sedan to show off its laser headlights. The badge for BMW's Carbon Core also gets some of the limelight here to proclaim the extensive use of carbon-fiber-reinforced plastic. This clip doesn't give much more away, though. However, BMW has already spilled the beans about some of the other futuristic features for the new 7 Series in an earlier tease. The sedan is essentially a rolling technological showcase and offers functions like remote-controlled parking that's run from the key fob. Inside, using the infotainment system is possible with three-dimensional gesture control by waving your hand in the air in the right area. The extensive amount of CFRP in the passenger cell also helps save 287 pounds over the previous generation. If buyers are really looking for opulence, they can also reportedly order a massive, panoramic glass roof and a leather-covered engine cover. Expect a full rundown of all of the 7 Series' lavish features when the sedan debuts.
