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.

Petrolicious reconnects with the BMW M coupe

With the look of a clown shoe on wheels, the BMW M Coupe was a product of using what was around to create something great. Starting with the Z3 convertible, BMW's engineering team added a bulbous roof to improve rigidity, and for the M version, it dropped in the inline six from the contemporary M3. While the result wasn't a beauty queen, the car more than made up for any aesthetic complaints in driving pleasure. Petrolicious talks to owner Alex McCulloch about just what makes the tiny three-door so special in its latest video. With a fairly short wheelbase, plenty of power, and a rear suspension from the E30-chassis BMW 3 Series, the M Coupe can be a quite handful at the limit. "I used to say it wanted to kill me, but now we've reached an agreement where it's not quite as murderous," McCulloch says. He's eventually found that the only real way to exploit the coupe to its fullest is on the track, where he competes in time trials. To get lap times as low as possible, the BMW now wears quite a few mods, but McCulloch says that it's all reversible. Figure out what competitive hang gliding has to do with driving in this clip from Petrolicious. Related Video:

BMW planning six-cylinder i9 hybrid to celebrate centenary?

On the prospect of a new BMW M1 based on the company's new i8 hybrid, the jury has been in and out so much that we can't even tell which way it's likely to go. However, the latest reports coming in from Germany suggest that BMW may have something else up its sleeves. Rather than make a conventional gas-powered version of the i8, Germany's Auto Motor und Sport says BMW will make a more powerful one.
Tentatively dubbed i9, the hybrid sports car is rumored to pack a six-cylinder internal-combustion engine instead of the i8's turbo three. Coupled to more potent electric motors, it would figure to produce even more than the 357 horsepower and 420 pound-feet of torque already on tap in the i8, with further weight reductions to offset the bulkier engine.
Auto Motor und Sport says the mooted model will be produced to celebrate the Bavarian automaker's 100th anniversary and eclipse the i8's performance, with a projected 0-60 run in under four seconds en-route to taking the gloves off to crunch the Autobahn in electric bliss. The new i flagship would be another member of the company's growing electrified family, joining the existing i3 hatchback, upcoming i5 minivan and possible i8 Spyder down the line.
