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.

Some younger drivers relish the idea of stick shifting

Part way into the 21st Century, obsolescence isn’t what it used to be, especially in the minds of younger consumers; consider the renaissance of vinyl records and film cameras. To that list, add the automobileÂ’s stick shift. Manual transmissions are no longer just about lower car purchase prices, better fuel economy or more control on the road. TheyÂ’re about being hip. At least, thatÂ’s part of the thesis offered in a recent article in The Wall Street Journal. “The 20-Somethings Fueling a Stick-Shift Renaissance”  examines a modest but real resurgence in the sales upticks of manual-equipped cars, and focuses on the enthusiasm of younger people to acquire them, and the challenges—no longer so challenging—of learning bow to drive them. But, as readers of Autoblog have learned in recent years,, the future of manuals, as author Rachel Wolfe succinctly points out in the Journal piece, is essentially doomed in the longer term. Blame the electric vehicle. She writes that car makers sold 43 different manual models in 2022, according to J.D. Power, compared with 69 in 2019. “While a few EVs do have more than one gear,” she says, “auto makers are still figuring out how to translate the experience of maneuvering a manual to their electric car lineups. ‘’ Did we mention “doomed”? But Ms. Wolfe does offer some positivity. “MINI just opened a manual driving school of its own at the BMW Performance Center in Thermal, Calif.,” she writes. “A January company survey of just over 1,000 drivers found that two-thirds of 18-to-34-year-olds are eager to learn how to drive a manual, versus 40% of older respondents who donÂ’t already drive stick.” The author quotes a couple of drivers who became enamored of manuals, including a teenager from Ohio who took his driving test with a manual. “I thought it was cool to learn how to drive on a stick, just because I could tell my friends that I was a better driver than them,” he says. She also visits the other side of the issue, talking to a 24-year-old, who said that she found the stick “cool,” but only until “her leg grew sore from the clutch as she navigated traffic commuting back and forth from law school every day in Tampa, Fla.  ‘I think they are very fun to drive for about two hours, and then youÂ’re like, OK, I would like to put it away and just drive like a normal person again.’’” The full article is available online here.

134K BMW 5 Series recalled for taillight issue

BMW is voluntarily recalling 134,100 cars due to a faulty ground terminal in the taillight bulb carriers, causing the sudden failure of brake lights, turn signals and reverse lights. The recall covers 2008 through 2010 5 Series models produced between March 1, 2007 and December 31, 2009, and includes everything from the 528i to the mighty, V10-powered M5. It's unclear if this recall is limited to sedans or extends to the 5-Series Touring.
There have been no reported cases of injuries, fatalities or crashes associated with the taillight issue. BMW will be issuing recall notices to affected owners in the coming weeks, asking them to report to dealers so that the bulb carriers on the taillights can be replaced. All repairs are, naturally, free of charge. Scroll down for the official recall notice from the National Highway Traffic Safety Administration.
