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.

NHTSA gives okay for three automakers to skirt tire-related recalls

BMW, Honda, and Mercedes-Benz are all going to avoid small recalls, after the National Highway Traffic Safety Administration issued petitions for "findings of inconsequential noncompliance" to the three manufacturers, according to Tire Business. Basically, the petitions allow the brands to avoid recalls for some very, very minor issues.
BMW had tire placards on 364 X6 M CUVs that stated the car could only handle four passengers, when in reality it had room for three in the back. Actual plausibility of fitting three real humans in the slope-roofed Bimmer aside, the Munich-based manufacturer argued it was inconsequential, as the placards were correct regardless of the number of passengers.
Honda's case focused on 212 2011 and 2012 Acura TSX sedans equipped with 18-inch wheels. The TPMS systems on these cars were set for 17-inch wheels, rather than the larger hoops, but even with the lower settings, the tires maintain adequate load capacity.

2016 BMW X1 First Drive [w/video]

Perhaps more than any other model, the X1 exemplifies the shift going on at BMW. That the X1 is the first front-drive-based car to wear the BMW badge in the US is both remarkable and doesn't matter at all. Some background: The first X1, sold here for the latter half of its six-year run, was an Old BMW. Based on E90 3 Series underpinnings, it was basically a tall, last-gen 3 wagon, a car on short stilts. We loved it. It drove almost exactly like a good 3 Series at a time when that 3 Series was no longer available. It sold in okay numbers. It's gone now. This new X1, the 2016 model, is a sort of about face, or at least a right-hand turn in the engine compartment. This is New BMW. The base engine is again a 2.0-liter four-cylinder, a new design based on the company's modular engine architecture that can spit out threes, fours, and sixes using the same component set. It's mounted transversely, not longitudinally like in the rest of BMW's US offerings. It loses some horsepower to the last X1's 2.0 (228 hp versus 240) and a bit of torque (258 lb-ft down from 260). Again, few will notice. The optional 3.0-liter turbocharged six from the last generation is gone. Not many customers chose it, and the six likely wouldn't fit under the hood of this rearranged X1. EPA fuel-economy numbers match those from the 2015 xDrive28i exactly – 22 mpg city, 32 highway – so no gains there. So packaging won. There's really no other explanation for the longitudinal-transverse swap, except that maybe it's less expensive to build this way. EPA fuel-economy numbers match those from the 2015 xDrive28i exactly – 22 mpg city, 32 highway – so no gains there. But the packaging advantages are abundant. The interior is somewhat narrow, but it's opened up a bit by the lack of a transmission tunnel that would normally eat space between the front occupants. Instead, the center console is set low, with a tall shift lever rising practically from the floor up to meet your hand. There's storage forward of the shifter and a folding center armrest that opens for small items. The original X1 was sold here with rear-wheel as well as all-wheel drive. For obvious reasons, that won't be the case this time around. BMW also won't sell a front-drive model here (although one is offered in Europe and elsewhere) likely because it would involve the admission that this is not your average BMW, but instead a New BMW, one designed for more people and fewer enthusiasts.
