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.

2015 BMW 228i xDrive

Has BMW lost its edge? The answer to that depends on what vehicle you're discussing. The company's products, while still quick and agile, are softer and more forgiving than they've ever been. And while this change may be worrying if we're talking about an M3 or an M5, is it necessarily a bad thing for more mainstream models? That's our question after a week behind the wheel of the BMW 228i xDrive, a vehicle that succeeds the beloved, driver-focused BMW 1 Series. In some ways this new car is a let-down, but in many other areas the new 2 Series is just plain better. The latter is particularly true if we're talking about the new sheet metal. While the 1 Series was a great source of compact, rear-drive entertainment, it wasn't a pretty car. The new 2 still isn't a stunner, but it benefits from BMW's latest design language. It looks wider and more muscular than the squat 1 Series, although certain elements, like the daylight opening and rear taillights, look like they were plucked right from the old car. Overall, BMW has crafted a more premium aesthetic for the exterior of its entry-level coupe. A weak spot for the 1er, the 2 Series cabin sports a similarly upscale redo. Like the last-gen car, the top of the dash is home to a master display for the iDrive system (a neutered, non-navigation version on our test car), while the lower half of the center stack is dedicated to analog controls for the HVAC and audio. The dash layout is similar to the 1 Series, but the execution feels more upscale. The trim around the radio and climate controls includes aluminum and gloss accents. The passenger side dash and center console ditch soft-touch plastic for authentic materials – our car uses real brushed aluminum, although piano black and wood are also available. As with all recent BMWs, the combination of the automatic gear lever, the knob and buttons of the iDrive system, and the toggle switch for the Driving Dynamics Control system mean there's a lot of clutter where the driver's right hand falls. What hasn't changed with the 2 Series is the excellent relationship between the driver and the primary controls. Our test car wears the Sport Line package, which does without BMW's obnoxious, too-large-diameter M Sport steering wheel. Instead, there's a thick-rimmed wheel with textured leather and red contrast stitching. It feels more natural than the oversized M wheel, while this car's large paddle shifters have a solid, well-damped action.

Take a look at the shocking Rolls-Royce Next 100 concept

Rolls-Royce showed off its Vision Next 100 concept today in London, giving a look at what its vehicles might look like a century years from now. Each BMW brand will show its own concept this year; BMW's Vision Next 100 concept was an interesting mix of textile-like patterns with stretchy fenders and a very 2010s four-door coupe shape, but this Rolls-Royce concept looks more like a luxury version of a World Solar Challenge racer. The car's official title is 103EX, following the convention of recent Roller concepts. Whereas its BMW counterpart was perhaps a safe, predictable vision of the future, the Rolls is a striking vehicle and a big departure for the brand. Whether it works as a whole for you or not, it represents the kind of stylistic provocation that made ex-BMW stylist Chris Bangle a household name. While the early Bangle cars were extremely controversial, this Rolls concept is clearly the heir of his penchant for sharply creased character lines. Call the rocker panel crease flame surfacing if you want. The floating headlamps and blade-edged verticality of the fenders are classic Rolls: imposing and visually heavy, without necessarily being classically beautiful. The square, flat grille is, to my eyes, much less successfully integrated. It seems like Rolls had the perfect opportunity to evolve the trademark grille into something more contemporary. In 100 years, the brand will still need to lean on this sort of anachronism? That seems short-sighted. We'll have more on this concept from our man on the ground in London later today.
