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.

Refreshed 2016 BMW 3 Series adds two new models to the range

The BMW 3 Series had years standing at the forefront of the luxury sedan segment, but competitors have continued to get better at challenging its long reign. To make sure the stalwart model can keep up, BMW is bringing some new powertrains and other upgrades to the range with a refresh for the 2016 model year. Plus, the exterior sees a very slight styling update. There are two big additions in the 3 Series range for 2016. First, there's the new 340i with the B58 turbocharged, inline-six engine to replace the 335i. Displacement is still 3.0-liters, but the latest mill makes 320 horsepower and 330 pound-feet of torque – gains of 20 hp and 30 lb-ft over the outgoing model. BMW estimates the 340i can reach 60 in 4.8 seconds with the standard eight-speed automatic or in 4.6 seconds with xDrive. A six-speed manual is also available as a no-cost option. The other new member of the family is the 330e plug-in hybrid, and it joins the lineup later in the year. BMW isn't specifically talking about the PHEV's powertrain, but the company estimates total output of 250 hp and 310 lb-ft. The sprint to 60 is forecasted at 6.1 seconds, and the range on electric power is predicted at 22 miles. Fuel economy isn't disclosed yet. Beyond these two models, there are a host of other upgrades under the skin for the 3 Series. The eight-speed automatic should be slightly more efficient thanks to wider gear ratio, and the handling is reworked with new front struts, rear dampers, and retuned electric power steering. There's also a Track Handling Package for gas-fueled models that combines Variable Sport Steering, Adaptive M Suspension and M Sport Brakes with high-temperature pads. The nav system accepts over-the-air map updates now, as well. You certainly can't see all of the changes on the outside, though. For the 2016 3 Series, BMW's designers tweak the front fascia slightly and update the headlights. LED units are optional on the 320i, 328i, and 328d, and they're standard on the 340i. The rear features reshaped LED taillights, and inside there's additional ambient lighting and chrome trim. In one other small adjustment, the look of the Sport Line package with black trim on the grille, B-pillars and rear bumper is now included on the 328i, 328d and 340i.
