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 preparing new M4 GTS with water injection

Last month, BMW revealed a new safety car for the MotoGP series. Only instead of just taking one of its production models and giving it some flashing lights, special livery and emergency equipment, the Bavarian automaker used the specially equipped M4 to showcase a new water injection system. And now word has it that the tech is being worked into a new M4 GTS. The system sprays water into the combustion chamber in order to lower the temperature of the air and increase the engine's efficiency, thus allowing it to produce more power without overheating, and relying less on ambient temperatures. It does require refilling a 1.3-gallon water tank in the trunk, though. According to Car and Driver, it's that same system that BMW will be installing in the new M4 GTS, taking the place of previous M3 GTS specials. If precedent is anything to go by, the M4 GTS will also be stripped of excess weight and feature a tighter suspension, stickier tires and more, in order to make BMW's muscle coupe even more hardcore and focused for the track. We could be looking at a debut as early as Pebble Beach in August.

Mini has become the Rover that BMW always wanted

BMW has been working for 20 years to build a successful line of British cars, and on the evidence of the second-generation Mini Clubman, it may have finally done it. That means it's time for all of us to get used to the fact that Minis aren't going to be that small anymore. Case in point is this new Mini Clubman, introduced last month and conspicuous by its size. Many of us who've pointed to BMW's stewardship of Mini as an example of retro done right bemoaned the Countryman subcompact SUV – a concept actually ahead of its time. The Coupe and Roadster, perhaps rightfully, deserved (and received) an eye roll. But now there's a so-called four-door hardtop that went on sale this year and this forthcoming, six-door Clubman that approaches the compact hatchback class in size. These vehicles actually look like practical moves at keeping buyers from defecting to larger cars made by someone else, rather than vain attempts at maximizing investment in a set of parts. And in an interesting twist, Mini is turning into one of its ancestors – minus the feeling of inevitable doom. Many of us were led to believe somewhere since Mini's relaunch about 15 years ago that the brand would be a stepping stone into the greater BMW fold. But in reality, it's done exactly the opposite, creating a parallel brand for those not willing to embrace the BMW image, but leaning heavily on British nostalgia. That was sort of the reasoning used when BMW pulled the Rover Group of England away from a fruitful partnership with Honda in 1994 and absorbed it all. In the consolidate-or-die '90s, it made sense. BMW had a small, but successful, line of sedans. Rover had no success outside of Western Europe (its last US attempt at selling cars, the Sterling, ended three years earlier). Yet its Land Rover line of SUVs was just right for the time and the 35-year-old Mini still had image-conscious clout. With every passing day, the brilliance of BMW's move to abandon Rover in 2000 seems brighter. Even ditching Land Rover made sense in the long run (and probably saved Jaguar in the process). With every passing day, the brilliance of BMW's move to abandon Rover in 2000 seems brighter. During a chat with Mini USA VP David Duncan this summer, it became clear the Mini of the past is probably gone. A small, city-sized Mini is not necessarily off the table, but larger and more profitable models are coming first.
