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.

Six 'shut up and take my money' cars

Any time you see this iconic moment in pop culture - Shut up and take my money! - posted in response to a new car reveal, rumor for an upcoming model or even lip-service to a vehicle that should exist, you can bet there's some intrinsic good in the idea. Though depending on the person offering up the cash, that good could take the form of extraordinary form, functionality, weight savings, power, handling, etc. You get the idea.
In fact, when I first proposed this list, I reached out to the Autoblog staff to help me brainstorm. Here are some of the ideas they offered up that I ultimately didn't use: Jaguar XE Coupe, Pagani Huayra Roadster, Mercedes-Benz S-Class "parade car" (cabriolet), Morgan 3-Wheeler with Ducati V-twin, Ford Transit Connectamino (pickup), Mercedes CLA63 AMG, Ford Fusion 5.0, BMW i8 Spyder, Lexus RC-F Shooting Brake, Volvo XC90 Polestar. Oh, and things we collectively wanted to stick Dodge's Hellcat in were almost as numerous as models that Fiat Chrysler Automotive currently makes (though none quite so compelling as the Grand Cherokee you see above.)
Ultimately though, while I used a couple of ideas from my colleagues, the list of cars I'd shell out for unquestionably is very personal. Though it isn't complete, what follows is a selection of cars whose very existence would prompt me - or the trust-fund-baby versions of me - to utter without hesitation: "Shut up and take my money."

BMW gets exemption to allow self-parking 7 Series in US [w/video]

The US-spec 2016 BMW 7 Series is gorged with enough technology for it to qualify as a finalist in our Technology of the Year award. But not all of the tricky bits found on the European-spec car are offered Stateside, like the automated Park Assistant Plus that lets a driver remotely move the car into and out of a parking space using the touchscreen keyfob. The reason is Section S5.3 of Standard No. 114 of the Federal Motor Vehicle Safety Standards, which dictates that "the service brake... be depressed before the transmission can be shifted out of park.'" Since Park Assistant Plus is remote controlled, the brake pedal isn't pressed when the car shifts from Park into a gear. Automobile reports that the National Highway Traffic Safety Administration has conceded the law is too vague, and granted BMW's request for an exemption to bring the convenience feature to the US. NHTSA said that the point of the law was to have brake actuation during the transition from Park to a forward or reverse gear, not to insist that someone actually presses the brake pedal. BMW said it plans to bring Park Assistant Plus to the US soon, but the carmaker doesn't yet have a firm timeline for the move. To us that seems like a small yet significant victory as the marketplace fills up with cars that have abilities beyond the current laws to manage. Now if we could just get that whole FMVSS headlight issues worked out and enjoy some of that tasty Matrix and MultiBeam lighting. You can watch a video of the BMW system in action in the video below.
