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.

April Fools' Day brings Jeep Sedan, Hyundai N Roadster, Toyota Yaris pickup and more

There is one day out of the year when public relations professionals have permission to lie to journalists and to the public: April Fools' Day. Manufacturers release details about wild, weird and wacky new technology, concept vehicles and services. Some take it to obvious outlandish extremes (Jeep Sedan anybody?), while others plot to mislead with products that are just outside the realm of possibility. Check out all the "jokes" below. BMW Motorrad BMW doesn't want to exclude anybody from experiencing the thrill of high-level racing, so it is introducing 'iRace" autonomous programming on its S 1000 RR sport bike. It includes beginner, sportsman, advanced and unlimited driving modes, and stores GPS information for all Superbike world championship tracks. Hyundai Hyundai is wrong for this. The Hyundai N Roadster is the work of South Korean designer Yeonjoon Park and features a 2.0-liter turbocharged engine, rear-wheel drive and a hard convertible top. Hyundai says this is a "concept (for now)," but we think it'd make a seriously great Mazda Miata competitor. Honda Honda wins the award for the best interactive gimmick, as its press release for the '90s-inspired special-edition Pastport includes a live hotline number with a message from Fred Savage. Call 1-833-PASTPORT for more information. Jeep Put the Jeep Cherokee face on the Chrysler 300's body, and voila! The 2019 Jeep Sedan is born. We can't decide if the name or the rendering is better. Land Rover Accessibility to charging ports is of major concern to anybody with a plug-in vehicle. So, with the recent launch of the Range Rover P400e and Range Rover Sport P400e, Land Rover is putting forth an effort to install more stations around the globe. First up is Scotland's Isle of Skye. Adventurers need juice too! Lexus Australia Lexus expands its Encore service to include doggos. The new service, called Enpaw, will take pups to luxury boarding kennels in style. Toyota U.S. Toyota created the Yaris Adventure pickup for "those who want to tell their friends they own a truck but never veer off pavement." It's part Mazda 2, part RAV4, 100 percent ute and it looks ... great? Creating a new segment might be all fun and games to Toyota, but Ford is reportedly considering a Focus-based ute in a similar, albeit larger, style. Toyota Australia Toyota is launching a new HiAce van, and it's already getting a limited-edition variant called the PieAce.

2016 BMW 7 Series First Drive [w/video]

Flagships demonstrate strength. "This is what we can do," these cars say with emphasis. Since 1977, the 7 Series has been a rolling showcase of BMW's capability. Sure, BMW makes racecars, but the mighty 7 is a proud reminder that the Roundel also stands for luxury. Except the 7 Series has been eclipsed by the Mercedes-Benz S-Class, a technological tour de force that Mercedes haughtily calls the industry's flagship. BMW makes a pretty nice car, but no one would dare call it that. Bimmer should probably just lower the flag, right? Not yet. Most of history's famous flagships have been fighting machines. They exude confidence, but also pack a punch. And with the 2016 7 Series, BMW is unleashing a broadside on Mercedes and the rest of the industry. Rather than raw power, the sixth generation of the iconic 7 Series is loaded with sophisticated technology that makes the new sedan more luxurious and comfortable. While it looks familiar from the outside, most of the improvements are in the cabin or under the skin. Things like the carbon fiber used for the passenger cell that help the 7 Series shed 190 pounds compared to its predecessor. Or the touchless gesture control that allows you to accept or decline phone calls with simple hand motions. Even the infotainment system is better, with a pinch-to-zoom feature that makes iDrive less confusing and more like the user-friendly iPad. BMW is unleashing a broadside on Mercedes and the rest of the industry. It's a lot of high tech stuff, but the driving experience is still the top priority for BMW. To test its mettle, we traveled to the Monticello Motor Club in rural New York. After several hot laps on the road course (more on that later) we slip behind the wheel of an Arctic Gray Metallic 750i xDrive for some public road driving. The big sedan immediately masks its size on the twisting rural state routes. With 445 twin-turbo V8 horsepower urging us forward, we barrel ahead as the countryside blurs by. Once we settle into a relaxed, legal pace and get our bearings inside the car, we check out some of the new tech. The gesture control is easy to activate while driving, and with a twirl of a finger we turn up the silky-sounding Bowers & Wilkins system. Gestures actually work as advertised. No one calls us, but during an earlier demonstration we were able to decline a call with a dismissive backhand. It felt good.
