BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.

Senior VP Hildegard Wortmann says BMW's electric journey is just beginning

Anyone who questions BMW's effort or sincerity on electrified vehicles should have a chat with Hildegard Wortmann, the German automaker's senior vice president over product management for automobiles and aftersales. I was fortunate to do just that at the Detroit North American International Auto Show earlier this year. ABG: Where might BMW go with electrified vehicles beyond your i3 urban EV and i8 high-performance hybrid sports car? "That [regulatory] train has left the station" - Hildegard Wortmann HW: I think a big advantage is that we now have two bookends: BMW i [green] and BMW M [high performance]. We can use those bookends to foster the BMW brand in total. Are electrified vehicles the answer to CAFE and European regulations? Is that the future? We don't know, but that [regulatory] train has left the station. To achieve all of these regulations worldwide, there is no way to do it without electrification. That is why the activities of BMW i are not just to launch new products. They are our build-up in competence for learning and gaining experience in electrification. We will use those learnings for the total BMW brand. Technology-wise, we now have a really good understanding of what to do, what not to do, how to work with this and how to get a lot of learnings from the infrastructure and everything that goes with it. And depending on how quickly the market takes off, we can scale it and use it across the range. We will use the competence we will have in vehicle electrification for more than just BMW i. There will be other derivatives and electrification of other products. ABG: Do you see BMW offering pure EVs with larger batteries for greater range? HW: That's a big feature of the Tesla. The question is to find the best balance [of range vs. battery size, weight and cost]. On the i3, we tried to have the right balance between how much range customers need for daily driving and how much battery we put in there. The market will show us. We have over a million kilometers driven by consumers in the Mini E and ActiveE and a fairly good understanding that those people are not driving that much. Putting a really big battery with all that weight into a car that is meant for urban mobility does not make sense. ABG: What about extended-range EVs beyond the i3's optional small range extender engine? "This whole EV movement is in its very early stages." HW: This whole EV movement is in its very early stages.

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.
