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.

Consumer Reports says these are the worst new cars of 2014

Consumer Reports has announced its annual list of worst vehicles, a cringe-inducing contrast to its list of top vehicles. Ignominiously leading the way in 2014 is Chrysler, which has a staggering seven models listed.
Jeep nearly sweeps the small SUV segment by itself, with its Compass, Patriot and 2.4-liter version of the new Cherokee, while the only midsize sedans listed by CR were the Chrysler 200 and Dodge Avenger. The new Dodge Dart and the Dodge Journey round out CR's condemnation of Chrysler.
Ford is taking heat as well, with the Taurus, Edge and their counterparts from Lincoln all listed as the worst vehicles in their respective segments. Toyota doesn't fare much better, with its Lexus IS, Scion iQ and tC also making the list.

Next-gen BMW M5 spied on Munich roads

BMW is still hard at work developing the next-gen M5 around the company's home base in Munich. Unfortunately, the Bavarians are keeping the super sedan plastered with camouflage, which makes picking out the details rather difficult. There are some tiny tweaks from the previous spy shots, though. Obviously, these are still early development vehicles, so it's hard to know whether these changes are in any way meaningful. Up front, this M5 still has an air intake stretching all the way across the lower portion of the bumper. The earlier shots showed this piece with a uniform width, but the designers added a little flair this time by lifting the center portion slightly for a more attractive look. Comparing the two examples in profile, the suspension has seemingly been lowered on the latest one to tuck the tires closer to the fender lips. Most parts have carried over, though, including the massive, cross-drilled brake rotors and quad exhaust tips poking out from the rear. The next M5 should have no problem backing up its mean looks, though. All indications, including earlier spy shots, suggest that the high-performance sedan will gain all-wheel drive, at least as an option, and power will be around 600 horsepower. While about the same as the current 30th anniversary edition, the future 5 Series will reportedly follow the lead of the latest 7 Series by going on a big diet thanks in part from a new, lighter platform.
