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 tests M Lap Timer App with M4 Coupe at Brands Hatch

The 2015 BMW M4 looks to include all the necessary ingredients to offer dynamite driving experience. It's an M car after all. But in today's constantly connected world, the experience of hurtling a car around a track isn't always enough.
We want data, and while there are some solid telemetry apps available for smartphones (notably Harry's GPS LapTimer), manufacturers have been a bit slower to develop their own dedicated mobile telemetry trackers for their performance cars. With the new M4, though, BMW is taking the plunge, allowing drivers to track their lap progress through a new app, creatively called the M Lap Timer.
To show off the program, BMW has recruited touring car racer Andy Priaulx to perform a fast lap in an M4 at the UK's Brands Hatch circuit. The accompanying video doesn't do much to show off the app in action. Rather, it give us a stylized look at the metrics as Priaulx hustles BMW's hottest 4 Series coupe around the circuit.

China's auto sales continue to drop

The days of unending growth of carmakers in China look to be over, and some analysts are even forecasting a net drop in volume this year, The Detroit News reports. After falling numbers in June and July, the China Association of Automobile Manufacturers tallied total sales, including trucks and buses, in August to 1.7 million, down 3 percent from 2014. There were some tiny specs of good news in China, but there's no turnaround in sight. Total vehicle sales from January to August are actually still up but only 2.6 percent. Like the rest of the world, SUVs are booming with numbers up 45.6 percent from the previous year. Honda managed a very impressive 50.7 percent gain on the strength of the CR-V and Vezel (the HR-V here), according to The Detroit News. Also, the country's domestic automakers, which generally offer less expensive products, posted a 2.5 percent growth in sales. The news continues to look bad for Detroit's automakers, though. Volume from General Motors dropped 4.8 percent in August, and Ford fell 3 percent in August. Both of them have invested significant amounts there in the past years. The vehicle industry in China grew last year, but there was burgeoning evidence of weakness. At the end of 2014, dealers there pushed back against huge inventories pushed by automakers. Even before the big drops began in June, GM saw the writing on the wall and started cutting prices. BMW responded to the slump by cutting back production to deal with the changing demand.
