Electrify Expo is an all-electrified auto show like the old days

In late July, Autoblog swung by Washington, D.C. to check out the Electrify Expo. Now in its third year of nationwide shows, the Electrify Expo calls itself “North America's largest electric vehicle festival filled with over 1 million square feet of the world's top electric brands.” At every stop, visitors can find out about, crawl around in, drive and ride just about any personal conveyance that uses a battery for propulsion. Truth be told, when the show's PR team reached out to us with an invite, we only considered going after finding out about an area showcasing battery-electric tuner cars. EV tuning is undoubtedly going to be huge—eventually—which got us curious about these early days. We figured weÂ’d brave whatever the rest of the expo was to find out whatÂ’s the equivalent of nitrous for a Tesla. See, the EV event scene is still such that one never knows if theyÂ’ll show up to a mix of science and county fairs with a few cars on display just for truth in advertising, or if theyÂ’ll show up to a parking lot with 26 cars, 10 of them locked, 10 of them homemade, and 6 guarded by promotional hires desperate to tap all your identifying info a tablet before dispensing dubious and superficial information. Which is to say, we didnÂ’t expect much. And that makes us chuffed to report: Electrify Expo is great. We hadnÂ’t been strolling the lot outside the old RFK Stadium for five minutes before thinking, “This feels like an old-school auto show!” The exclamation to that point came from a group of four who cut me off to reach the C40 Recharge in the Volvo booth, one of them exclaiming as if he were the group expert and as if his friends were deaf, “THATÂ’S THE LEAST EXPENSIVE ONE! AND ITÂ’S BEEEE-YOUUUUU-TI-FULLLLLL!” I wasnÂ’t there to judge, I was there for the enthusiasm. Automakers had built small, simple, open booths, parked cars in them, then provided visitors the kind of interactions that will do the most good for anyone wondering about or interested in an EV. We only saw two cars that were off limits, the new Volkswagen ID.Buzz and the Ford F-100 Eluminator. Volvo wouldnÂ’t let me get an espresso from their chic little trailer, either, unless I visited the EX90 Experience trailer first. Otherwise, it was a free-for-all. Tesla had a large booth full of cars. BMW had two i7s open for everyone to sit in, next to the Ford booth with that Eluminator and an unlocked Mustang Mach-E GT and F-150 Lightning showing their cooler-chest-frunk trick.

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 patents strange three-cylinder pushrod engines, perhaps for cruiser motorcycle

For decades BMW's motorcycles were easily identified by the two opposed cylinders sticking out of each side of the bike. While you can still find this layout on some of its products, these days the company also uses a variety of other layouts, depending on the model line. Based on European patents, there might even be a Bimmer in the ranks eventually with an absolutely bizarre-looking W3 configuration. BMW actually has two separate patents on these W3 designs, and both of them have the goal of cramming three cylinders into the space of a traditional V-twin. The first splays the cylinder out into a fan shape with pushrods operating the valves. The description submitted to the World Intellectual Property Organization describes the solution as, "The embodiment according to the invention represents an as of yet unknown type of W-3 reciprocating piston internal combustion engine having cylinder angles which can be largely freely sized." The other solution is more of a modification to the traditional V-twin. Two of the cylinders share a crankpin, but the third has its own and is positioned inside the angle of the V. It's a very odd-looking engine. With BMW's assertion that these designs are meant to fit in place of a traditional V-twin, Jalopnik speculates that they could be for a future cruiser from the company, and that would make sense. While brand offers a line of sport tourers with the K1600 line, it doesn't have something more classic to take on the likes of the Ducati Diavel. Creating such a weird engine would probably grab early interest from riders.
