2015 BMW X4 configurator is ready to get personal

The 2015 BMW X4 configurator is ready for your special touch. Starting with the 300-horsepower xDrive35i that starts at $48,925 after destination, our special touch aimed at a luxury cruiser and added $9,250 to proceedings for a final tally of $58,175. That got us the Technology, Lighting and Driver Assistance packages, navigation and enhanced USB and smartphone integration. We were tempted to go for the Dynamic Damping Control for just $1,000 and a set of 20-inch M Double Spoke Wheels, but the configurator didn't want to mix the M Sport Line with our Sparkling Brown metallic exterior hue so we skipped it.
We've covered the details on pricing and the breakdown of the order guide elsewhere, so you can always click through for refreshers. Or you can skip all those words and dive straight into trying to build an X4 that makes you say, "Yeah, now I get it."

1972 BMW 1602e EV concept looks glorious

Pretty sweet. That's a first impression of one cherry-looking experimental electric vehicle from BMW from way back in the day. Or at least from someone who for a time drove a '74 2002. A gas-powered one, that is. BMW built two experimental vehicles in 1972 based off of the old 1600 (which evolved into the 2002) model and even showed them off during the Munich Olympic Games of that year. BMW strung together a dozen typical car batteries and linked them to an electric motor made by Bosch. The result was a battery pack that weighed about 770 pounds (A quick modern-day comparison: a Nissan Leaf battery pack weighs about 480 pounds). Bimmer recently posted a two-and-a-half minute video about the project. The clip doesn't say how far those cars could go on a single charge, but did use to the vehicles to "escort" long-distance running competitions at the Munich Games, since there was no exhaust to choke those athletes out. The timing is fortuitous, of course, as the German automaker looks to continue to gain more goodwill from the green-car set through its new "i" sub-brand of plug-in vehicles, including the i3 electric vehicle and the i8 plug-in hybrid.

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.
