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.

Rolls-Royce Cullinan and BMW 8 Series spied south of Death Valley

Recently, we've stumbled upon a number of manufacturer prototypes running around. Usually, spy photographers sit and wait for hours with cameras primed in order to get a few shots of a car. We just got lucky. First, we caught the new Chevy Corvette ZR1 convertible during a Facebook Live video. A week or so later McGraw snapped a video of a ZR1 coupe cruising in his neck of the woods. Today, our ace photographer Drew Phillips caught a BMW test fleet filling up the new Rolls-Royce Cullinan and 8 Series coupe in Baker, Calif. Baker sits along Interstate 15, about halfway between Los Angeles and Las Vegas. It's just south of Death Valley, and, being late August, suggests that BMW was doing some hot weather testing. Drew was filling up his car when the fleet rolled in. There were at least two of the new king Rolls and a single 8 Series. Both cars were wearing a full swirl camouflage wrap. It's not an uncommon place to see prototypes. Still, seeing a whole fleet roll in is quite a sight. We've seen official photos of the Cullinan before, but these pictures give us our best view of the profile and rear we've had so far. From a distance, it looks like a high-riding version of the new Phantom with a hatch in place of the trunk. The taillights are obviously just filler units. Expect the final version to look very much like the squared off LED units on the Phantom. Likewise the interior and engine should be straight from the Phantom. That means a twin-turbocharged V12, though power is likely to be sent to all four wheels. We've seen the full BMW 8 Series concept a few times now. The proportions on the production car look the same, with a long hood and even longer wheelbase. The nose isn't quite as aggressive as the concept, but we expected the styling to be toned down to meet crash and safety standards. As for engines, look for six, eight and (hopefully) 12-cylinder power under the hood. A plug-in variant is also expected. Both cars have been in development for a long while, so look for full debuts sometime this auto show season. Maybe we'll happen upon some more test mules between now and then. Related Video:

2015 BMW i8 [w/video]

The most important thing to keep in mind while driving BMW's all-new i8 is that it's not a product of the company's vaunted M division.
Sleek sports-coupe design, carbon-fiber construction and blistering acceleration may cause automotive enthusiasts to drool, but the i8 has not been conceptualized, engineered or assembled to be another one of BMW's world-class track stars. Instead, the i8 has been hatched as a progressive sports car from the Bavarian outfit's new i division, which "represents visionary electric vehicles and mobility services, inspiring design and a new understanding of premium that is strongly defined by sustainability." Think of it as thrilling, but with an engaging environmental twist.
It's nearly impossible to walk up to the i8 with stopping twenty feet short and taking in its styling. There's no other production car as visually fascinating - this BMW is showroom-ready sculpture that captures all of the essence of the Vision Efficient Dynamics Concept that wowed crowds at the 2009 Frankfurt Motor Show. The wind sees it as a 0.26 drag coefficient, but humans will study its beautifully crafted carbon fiber and glass panels and realize they're in the presence of the future.
