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 launches new M Performance accessories for M5, M6

Those looking to make their stock BMW look like an M model might be interested in an M Sport package. But those who already drive an M model and want that extra bit of attitude to take it over the top look towards the M Performance Accessories catalog, to which BMW has just added a new range of add-ons for the M5 and M6.
The new range of accessories include a titanium exhaust from Akrapovic that's 22 pounds lighter and an extra bit throatier than the stock unit. BMW's also offering a carbon-ceramic brake kit and 20-inch alloys to accommodate them, as well as a carbon aero kit, carbon interior trim and those trademark stripes for the truly extroverted BMW performance enthusiast.
You can check them out in the gallery above and the press release below to see what Martin Tomzczk, the DTM driver sponsored by BMW M Performance Accessories, chose for his matte black M6 Gran Coupe daily driver.

BMW Concept Roadster has two fewer wheels than we were expecting

The annual Concorso d'Eleganza Villa d'Este on the shores of Lake Como is an opportunity for some of the most beautiful vehicles in the world to descend on one of the poshest places on earth each year. Unsurprisingly, the event is also increasingly the chance for automakers to debut exclusive concepts to some of the wealthiest auto enthusiasts in the world. In the last few years, BMW has become the masters of this annual unveiling with automotive concepts like the Gran Lusso Coupé, BMW Zagato Coupe and motorcycles like the the gorgeous Concept 90, not to mention the just-revealed Mini Superleggera Vision. But this year the Bavarian automaker has been somewhat tricky.
What would you first think when you heard of the BMW Concept Roadster? A lithe, two-seat convertible? Nope. This roadster is a cut-down, minimalist motorcycle with an ultra-modern design. As opposed to the retro looks of the Concept 90, this naked bike looks like it could fit in a BMW showroom tomorrow and not seem out of place.
The Concept Roadster packs the brand's classic two-cylinder boxer engine displacing 1,170 cubic centimeters and producing 123 horsepower and 92 pound-feet of torque. That power is routed to the rear wheel via a cardan drive, essentially a driveshaft, with a single-sided swing arm rear suspension. It's all nestled in a tubular spaceframe.
