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 wheels out single-cylinder G 310 R motorcycle

BMW makes a lot of motorcycles, including cruisers, enduros, off-roaders, sport bikes, and scooters. The one thing it hasn't done is a single-cylinder motorcycle with less than half a liter of displacement. But that all changes with the arrival of the G 310 R. Previewed by the Concept Stunt G 310 revealed last month in Brazil, the new G 310 R is BMW Motorrad's first sport bike with an engine smaller than 500cc. Though developed in Germany, the G 310 R is built in India around a new liquid-cooled single-cylinder engine displacing just 313 cc. That tiny cylinder does boast four valves, along with dual overhead camshafts and electronic fuel injection. It makes 34 horsepower and 21 pound-feet of torque. The engine is nestled into a compact tubular steel frame. It features a single headlamp up front, a molded fuel tank, 17-inch wheels, disc brakes with ABS, and aggressive styling. It all weighs just 350 pounds, with a seat that's less than 31 inches off the ground. Along with the G 310 R, BMW also revealed an electric motorcycle concept based on the S 1000 RR. That one you can check out on Autoblog Green. For a closer look at the G 310 R, you'll want to peruse the extensive image gallery above, and for further details, the press release below. BMW Motorrad G 310 R The new BMW G 310 R – the first BMW roadster under 500 cc. One cylinder, low weight, powerful dynamic performance – the BMW G 310 R embodies the pure essence of a BMW roadster: it has neither too little nor too much of anything. Pragmatic in the best sense of the word, it offers precisely what is needed – for dynamic performance and comfort, both in town and out in the country. The BMW G 310 R takes these essential qualities into a capacity segment that is new to BMW Motorrad. As a genuine BMW roadster it masters a range of disciplines: it is just as happy winding its way nimbly and flexibly through the narrow streets of a city as it is travelling supremely and powerfully along country roads. And thanks to its exceptionally low level of fuel consumption and a relaxed, comfortable seating position, it offers the welcome capability of being able to cover a long distance at a time. At home on the roads of the world. Newly conceived from scratch, the G 310 R represents everything BMW Motorrad stands for: innovation, quality and of course many years of carefree partnership with its owner.

BMW reveals i8 Concours d'Elegance Edition ahead of Pebble Beach

If you want to be among the first owners in the United States of the new BMW i8, the Pebble Beach Concours d'Elegance will be the place to be next Saturday. That's where Gooding & Company will auction off this one-of-a-kind hybrid supercar.
The BMW i8 Concours d'Elegance Edition was previously slated to be the very first i8 in North America, but has now apparently been downgraded to the guarantee of being among the firsts. In any event, it packs a series of special touches to make it unique. For starters, it's decked out in matte grey with unique brown leather upholstery, blue accents and Pure Impulse Tera World trim, with BMW i8 logos embossed into the headrests, special treat plates and the signatures of several key BMW personnel on the rear parcel shelf.
Pending government approval, it's set to be the first vehicle in the US fitted with laser headlights, and comes equipped with a special key, Louis Vuitton luggage and a "professional edition" BMW Charging Station. Scope out all the details in the press release below and take a closer look in the gallery above.
