Watch the BMW i8 get wrung out on the Ring

Been wondering where the heck the reviews of the all-new, plug-in-hybrid BMW i8 have been? After all, the car isn't exactly new, having debuted in concept form way back in September of 2009. In August of last year, we even tested a prototype of the new supercar. Despite that, though, we still haven't gotten a crack at the actual vehicle that will be sold to the public.
Well, we're happy to tell you that we're currently testing the i8 and will have a proper review for you soon. If, however, you're just aching for some coverage of the low-slung plug-in, we have a short video of it in action around Germany's famed Nürburgring.
Despite it's three-cylinder, turbocharged gas engine, the i8 sounds pretty angry as it laps the Ring. That is, until it has a little bit of a breakdown. According to the guys that caught the car on video, it appeared the i8 had a minor brake issue, and was parked on the side of the track for a good 15 minutes, with the driver pumping the brakes. We should probably just take this as proof, then, that manufacturers are actually using the Ring for testing, and not just messing about.

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.

Here are this year's top 5 automaker April Fools’ jokes

April 1 is the wonderful day when PR departments really push themselves to top the zany jokes they came up with the previous year. And it's not just fast-food chains competing with each other, or breweries announcing they have released stuff like a fermented herring flavored beer: carmakers' media teams rarely miss out on the opportunity to play a little joke on their audience. Here are a few of our favorites from this year:1) Porsche Porsche announced that it's launching a Mission E tractor, styled to resemble its 1950s tractor models. "With a power output in excess of 700hp, the Mission E Tractor will be the fastest accelerating agricultural vehicle in the world, enabling farmers to harvest crops in record time with the added environmental benefits of zero emissions at source and significantly reduced operating noise."2) Lexus Lexus actually jumped the gun, telling us on March 28 that it's combining cars and drivers using DNA matching. The kicker was that with DNA-matched cars, owners would be able to start their Lexuses by licking the steering wheel.3) McLaren Automotive McLaren said it's boosting efficiency by quite eccentric measures, such as measuring the technology center's lake and floor tiles daily, and by synchronizing the staff's tea breaks.4) BMW Motorrad BMW's motorcycle arm is solving parts availability issues in remote locations by offering a 3D printer mounted permanently on the bike's rack: If you need to replace a broken-off gear lever, you can just print one. "The new system will mean that even very rarely required parts not generally stocked by BMW Motorrad sales partners can be supplied on a just-in-time basis." BMW even went to the lengths of announcing that the "BMW Motorrad iPart 3D Mobile Printer" was tested on the Antarctic, by erecting a tent whose poles were produced onsite.5) Honda Last but not least, Honda UK purportedly cut the roof off a new CR-V, calling it the CR-V Roadster. Tellingly, no convertible top was even offered for the concept, "making it a no-top rather than a drop-top. This innovative design makes it a vehicle purely for sunnier climates and therefore completely useless for the two-day British summer which traditionally occurs in May."Related Video: Featured Gallery Top 5 April Fools 2018 Image Credit: Porsche Green Humor Weird Car News BMW Honda Lexus McLaren Porsche bmw motorrad mclaren automotive
