BMW swaps 30i and 40i models into 2017 2, 3, and 4 Series

BMW will continue its staggered rollout of new engines to many (but not all) of its products in 2017. The new modular engine architecture is the basis for three-, four-, and six-cylinder engines, some of which are already stuck in new Minis and a handful of BMWs. With those new engines come new (or in some cases resurrected) badges meant to connote the added power. They have the added benefit of further separating the last two numbers of the models from the actual displacement of the engines, which is always fun. BMW calls its latest 2.0-liter four-cylinder engine B48, and the new single-turbo six is the B58. The B48 cars get 30i suffixes and the B58s say 40i on the back. And if you really want to get down into code numerology: the B48 replaces the N20 four and the B58 supersedes the N55. Here's where they're headed next year: 2 Series: 230i and M240i For the small Bimmer, the 228i and M235i names are replaced by 230i and M240i models. In these applications, the four-cylinder makes 248 horsepower and 258 lb-ft of torque and the M-ish six makes 335 hp and 369 lb-ft of torque. The 2 gets other updates for 2017 as well. 3 Series: 330i sedan/wagon/Gran Turismo and 340i Gran Turismo For 2016, BMW put the 335-hp B58 six in the 3 Series sedan only. That engine spreads to the 340i Gran Turismo for 2017, and the N20 in the 328i is replaced by the B48 for 330i models in all body styles. There's still no six-cylinder wagon, and the 320i sedan keeps its N20 engine. Diesel sedans and wagons keep both the 328d name and the 2.0-liter four they had before. Trivia: The 330i name is being recycled – it was used on the E90 most recently. 4 Series: 430i and 440i Every 4 Series – including coupe, Gran Coupe, and convertible models – gets a new engine for 2017. Woo! And both engines will again be available with or without xDrive all-wheel drive. Woo. And no, that's not an official BMW photo above. The rest? BMW hasn't shared information on its 2017 crossover lineup, but we expect the X1, X3, X4, X5, and X6 will get new engines where applicable. And then there are the 30i and 40i models that already existed and won't be getting these new engines. The 330e iPerformance plug-in hybrid sedan already has the B48 four-cylinder. And the 540i, 640i, and 740i continue with a version of BMW's last-gen six. Got that all straight? Yeah, neither do we. And expect updates once the details on the 2017 crossovers are shared.

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 wants to expand DriveNow carsharing program to 25 new cities

Daimler's Car2go car-sharing service just announced that it will debut in Rome, its 26th global city. Now, BMW says it wants to expand its own carsharing program to, wait for it, 25 more cities. Coincidence? We think not. BMW is looking to bring its DriveNow carsharing program, with its Mini Coopers and 1 Series, to as many as 15 new cities in Europe as well as 10 in the US, Bloomberg News says, citing comments BMW executive Peter Schwarzenbauer made at the Geneva Motor Show last week. The service is now operational in Berlin, Hamburg, Cologne, Munich, Dusseldorf and San Francisco and serves about a quarter-million people. Of course, it's that last city, where DriveNow started operations in August 2012, that's been somewhat problematic. San Francisco has tough guidelines when it comes to where the cars can be parked, with so few public parking areas to choose from. DriveNow charges $39 for membership in San Francisco, then $12 for the first half hour of driving and 32 cents for each additional minute. DriveNow competes directly against Car2go, which charges around $25 to become a member and then 41 cents a minute to rent a Smart ForTwo.
