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.

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.

Rolls-Royce sketching out SUV for possible 'late 2017' release

With each new story on the Rolls-Royce SUV, the Goodwood automaker comes off as more at ease with their reluctantly birthed yet necessary sport ute. Company design chief Giles Taylor told Autocar that his team is still "sketching to assess the viability of the concept," which to ours ears means they're trying to figure out if such a beast is even possible within the confines of the brand. If it is, Taylor says it will be "a shooting brake, not a crossover with a sloping roof. A proper SUV."
A different company source, unnamed, seems confident that Taylor's team will figure it out, telling the magazine it would start at 200,000 pounds ($335K US). However, that same source said the vehicle will be "a kind of Mercedes-GLK-plus-plus," which is a baffling description in several ways. More reasonable is the speculation that it will ride on Ghost, not Phantom, architecture and make its debut sometime around late 2017.
That Ghost platform is expected to take cues from the carbon, aluminum and steel bones that supported the BMW Vision Future Luxury concept shown at the Beijing Motor Show and destined for the 9 Series. Some of those tricks will also go into the next-generation Phantom, which Autocar says will come in 2017 and not 2020.
