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.

2014 BMW 740Ld xDrive does diesel in a big way

Slowly but surely, BMW is expanding its lineup of diesel-powered models here in the United States. In addition to the 328d sedan and wagon, 535d sedan and X5 xDrive35d crossover, we now have this, the BMW 740Ld xDrive (not to mention the refreshed 2015 X3 xDrive28d that also makes its debut here in Chicago). As its name - and the photos above - suggest, this means BMW is offering diesel power in its flagship, long-wheelbase 7 Series sedan, set to directly compete with the likes of the excellent Audi A8 TDI.
Under the hood is BMW's familiar 3.0-liter turbocharged diesel inline-six, delivering 255 horsepower and 413 pound-feet of torque, all of which is sent to the road via the company's xDrive all-wheel-drive system and ZF eight-speed automatic transmission. That torque thrust is available straight away from 1,500 rpm, and BMW says the 740Ld xDrive will sprint to 60 miles per hour in a very respectable 6.1 seconds. Official fuel economy estimates haven't been released yet, but we expect the car to net highway fuel economy ratings in the mid-30 range.
The 740Ld xDrive arrives in BMW showrooms this spring, priced from $82,500, not including $925 for destination. We're pretty stoked to drive it. But in the meantime, have a look at fresh images of the big sedan live from the Chicago Auto Show, above.

BMW just the latest automaker to realize China will want a lot of EVs

News about China and cars isn't in short supply these days. With several of the world's largest cities, millions of cars on the road and huge problems with air pollution, it's no wonder that the nation is trying to make some changes. Along with decommissioning many of its aging vehicles, China is also expected to see huge growth in its electric vehicle market. BMW, as other automakers already have done, sees this as an opportunity to sell more cars. "We expect that the Chinese car market for electromobility will become the largest markets for those cars in a few years," says Karsten Engel, BMW's China head. BMW is collaborating with Shanghai's State Grid municipal power company to put public EV charging points at the former World Expo site, and the city plans to create 45 more by the end of the year. These will charge many different vehicles made by BMW and other brands. Tesla, which began delivering its Model S to China last month, plans to build its own supercharger network for the country. BMW plans to begin selling the battery-powered i3 and i8 plug-in hybrid in China this fall. BMW hopes to sell more than 400,000 vehicles in China this year. Fewer than 1,000 of those will be the i3, though, says Engel, due to a lack of supply. So far, China is falling drastically behind its own targets to get EVs on the road. With a goal of 500,000 by 2015, fewer than 70,000 EVs are currently operating in China. This numbers gap doesn't necessarily mean that the demand is or isn't there yet, but more and more automakers are betting it will be, and soon. Volkswagen is planning a fleet of electrified models for China by 2018 (at least 15 models according to Bloomberg). Daimler is teaming up with China's BYD to build EVs (and, of course, Your Dreams). Other Chinese companies are getting into the game as well.
