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 bringing two new concepts to Pebble Beach

BMW has announced that it will reveal not one, but two new concept cars during Monterey Car Week next month. The Bavarian automaker released this teaser image in conjunction with the announcement, showing what looks like a rather racy steering wheel to suggest that at least one of those concepts will be focused on performance. The signature red and blue stitching on the wheel and the participation of the M division's R&D chief in the press conference also hint at its nature. We're intrigued, though, by some of the buttons on the wheel with labels like "Flash," "Cool," and "PSL." The Roundel marque has been known to create concept cars to showcase at classic car concours, but they're more often presented at the Concorso d'Eleganza Villa d'Este that BMW has supported for over a decade on the shores of Italy's picturesque Lake Como. That's where BMW revealed in recent years the 3.0 CSL Hommage, the Pininfarina Gran Lusso, and the Zagato Coupe concepts (to name just a few). It did, however, follow up on the latter with Zagato Roadster concept at Pebble Beach that same year. We might project that at least one of the concepts would represent another brand affiliated with BMW – like Mini, Rolls-Royce, or BMW Motorrad. However the announcement below seems to indicate fairly clearly that they'll both be "concept cars" (not bikes), and that they'll be presenting the BMW brand itself (not another from the group). The show cars are also likely to veer more toward the design-study end of the spectrum than previewing any specific upcoming production models, and we wouldn't be surprised if the two arrived as a matching pair of sorts. BMW's California-based Designworks studio is also likely to have played a key role in at least one of the projects. But to find out more, we'll have to wait for the press conference on August 13 in the BMW Villa at Pebble Beach. The concepts will subsequently make the rounds of key Monterey events, including The Quail, the Legends of the Autobahn Concours d'Elegance, the Rolex Monterey Motorsport Reunion, and of course the headline Pebble Beach Concours d'Elegance. BMW to Unveil Two World Premier Concept Cars During Monterey Car Week. Media Preview at The BMW Annual Press Conference on Thursday Evening. Woodcliff Lake, N.J. – July 17, 2015... BMW is pleased to invite credentialed media to the 'BMW at the 2015 Monterey Car Week' preview press conference on August 13th at 6:00pm.

Mercedes G63 vs. BMW i8: Our silly drag race between the past and future

You see, we were just trying to conserve resources. We had Milan Dragway rented for a test of the AMS Alpha 10 Audi R8, and there was some extra track time, so we brought these two along. That's called saving money. Or something. Aside from being German, the G63 and i8 couldn't really be much more different – one is a prehistoric military vehicle with a nutty twin-turbo V8, the other a vision of the near future of efficient sports cars. So what did we do? We lined them up against each other, editor-in-chief Michael Austin in the i8 and me in the G-Wagen. Though we had a good idea of the likely winner – note which car the boss is driving – the results were still surprising. Watch for yourself above.
