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 5 Series Gran Turismo won't be a one-and-done model

The BMW 5 Series Gran Turismo seems like a model without a real segment to fit into. It doesn't quite match the mold for the swoopy four-door coupe niche like the Porsche Panamera or the brand's own 6 Series Gran Coupe. However, the vehicle isn't really a station wagon to appeal to those utilitarian buyers, either. Despite this identity crisis, BMW is reportedly prepping another GT for the next-gen 5 Series platform. According to German magazine Auto Motor und Sport, the 5 Series GT somehow has been a big enough sales success in the US and China to warrant another model. The next one would allegedly arrive in 2016, which is the about the same size as the future 5 Series sedan. The magazine speculates the new GT could lose about 221 pounds in the transition and be offered with four- and six-cylinder powertrains, plus a plug-in hybrid with an electric driving range estimated at around 19 miles. Globally, China is actually the larger 5er GT market than the US. According to IHS senior analyst Stephanie Brinley to Autoblog, the variant sold 21,089 units worldwide in 2013 (2014 is still being tabulated), and that represented about 5.7 percent of the 370,930 total sales for the 5 Series. China bought 42 percent of the world's GTs, compared to about 10 percent of the mix from the US. Europe, meanwhile, took about 29 percent of them that year. While the GT's sales figures make up just a fraction of the overall 5 Series, the variant is still a moneymaker for BMW, and IHS forecasts a second generation, too. "The 5 Series range as a whole is stronger for having this product, and it's very likely that the company's profit margin is higher on the GT, even with the cost of some dedicated sheetmetal and tooling," said Brinley.

BMW-Toyota partnership to spawn hybrid supercar

BMW and Toyota inked a partnership some time ago to develop green technology, and while we were excited by the idea of a reborn Supra with BMW's carbon fiber reinforced plastic slashing the curb weight or an ultra-efficient, hybridized 1 Series, the joint efforts have been rather limited. That's set to change, though, according to a report from Australia.
Motoring reports that the partners have come to terms on a sports car. And not just any sports car, but a lightweight, hybridized model, with a six-figure price tag. Lending a bit of street cred to that idea is the site's claim that Toyota is currently carrying out durability testing on the BMW i8. According to the site, the new model will slot into the spot left by the Lexus LFA, although based on the language used, it's unclear if this is the Tokyo-bound vehicle we mentioned several months ago.
Details on this potential car are limited, although Motoring claims it will use a Toyota hybrid system mated up to a BMW gas engine - likely the 4.4-liter, twin-turbo V8 found in the M5 and M6. That sounds pretty amazing to us, but we'd still advise taking this with a grain of salt. What would you like to see out of a joint-venture supercar from Toyota and BMW? Let us know in Comments, and have your say on the prospects of a hybridized, twin-turbocharged V8.
