BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

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 to show car that can park itself in a multi-story garage at CES

Automatic parking systems are something of a novelty, in their present form. Sure, modern parallel parking systems work well enough. And they're great if you lack the special awareness required to complete such a task. But frankly, how often is the average owner of such a system in a position to use it? Perpendicular parking systems, meanwhile, are basically an admission that you don't really deserve a driver's license. Novelties these systems may be, but they promise a future where we won't even need to be behind the wheel to park our cars. BMW is going to deliver a vision of that future at the 2015 Consumer Electronics Show with the Remote Valet Parking Assistant, a smartwatch-activated system that takes the driver out of the parking equation and replaces them with an advanced collision avoidance system. Fitted to an i3 for CES, the BMW system relies on four laser scanners to map the surrounding environment and identify obstacles. Combined with a digital site plan for a building, the company claims its car can navigate its way to an open parking spot, moving around even unexpected obstacles like improperly parked cars. The car's owner can step out of the vehicle at the intended destination, and then tap the smartwatch app for vehicle parking and retrieval. BMW claims this system will allow more precise control than GPS, particularly in something like a multi-story parking deck. While it's an intriguing route with autonomous technology, we wonder how much is required of these digital site plans. There are more practical uses of this technology, beyond valet parking. According to BMW, the collision-avoidance technology can aid a driver in low-light conditions, automatically braking the car for its driver when an obstruction is detected.
