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.

BMW chooses Tesla's Supercharger network for its future EVs

BMW, following the lead of many other automakers, has confirmed this week that it will adopt the North American Charging Standard (NACS), delivering EV drivers in the U.S. and Canada access to Tesla’s Supercharger network. The move goes a step further in cementing NACS as the universal system of choice. The conversion to Tesla plugs will begin formally in 2025 for BMW, as well as its Mini and Rolls-Royce brands in the U.S. market. Those marques now use the Combined Charging System (CCS) for EV charging. “It is our top priority to ensure that our drivers have easy access to reliable, fast charging," said Sebastian Mackensen, President & CEO, BMW of North America. NACS, which began as began as TeslaÂ’s proprietary charging connection, rapidly has become the new standard in its native land after Ford announced it would adopt it this past summer. This was quickly followed by General Motors. Since then, brands including Rivian, Mercedes-Benz, Volvo, Nissan, Polestar, and Jaguar have climbed d on board NACS. Earlier this month, the Hyundai Motor Group announced it would also provide customers with the NACS connector across its namesake, Kia, and Genesis marques. BMW says it will work across its three marques in the coming months to ensure a smooth transition to TeslaÂ’s charging network by early 2025, and owners will be able to pay for charging using their respective vehicle brandÂ’s own app. Related Video: How to charge a non-Tesla on a Supercharger

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
