BMW M4 Coupe laps 'Ring in 7:52, bests outgoing M3

Comparing Nürburgring Nordschleife lap times is a bit of a black art, especially when looking at times officially set by manufacturers matched against other sources. Driver skill and weather conditions play a huge roll in determining a quality time. Still, it appears BMW fans have reason to celebrate because the new M4 Coupe beat the previous-generation M3 by 13 seconds in a recent test by Germany's Sport Auto magazine.
Sport Auto conducts what it calls the Supertest, where it runs performance cars around the 'Ring and the short course at Hockenheim to create its own database of comparable times. The M4 with a dual-clutch transmission, ceramic brakes and Michelin Pilot Supersport tires managed a quality 7 minutes 52 second lap around the 12.8-mile course, compared to 8:05 from the last M3, according to BimmerPost. The new coupe also beat the magazine's posted times for the Audi RS5 Coupe, which did it in 7:59, and Mercedes-Benz C63 AMG with an 8:01, but couldn't quite match the 7:44 set by a 911 Carrera S. Still, BMW must be somewhat pleased with these results of its new 425-horsepower coupe because it posted the magazine's cover and an image of the time on its official M Facebook page.
While the M4 apparently stands up to contemporaries and predecessors, new generations of the AMG and RS models are reportedly on the horizon. In other words, more tests will come.

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.

BMW 5 Series future: 3-cyl engines and 600-hp M5

What if we told you the next BMW M5 would crest 600 horsepower? You probably wouldn't be too surprised, considering the steady increase in output that's accompanied each preceding generation. Now, what if we told you that the next BMW 5 Series would be available with a three-cylinder engine? Yeah, that'd be a surprise. But it may be a reality, according to a new report from Car. In its roundup of information on the next-gen BMW 5, code-named G30, the Brit mag predicts the new sedan will arrive in the summer of next year riding on an all-new platform that trims nearly 180 pounds of body fat through the use of high-strength steel, aluminum and carbon fiber. That platform, called the CLAR, which is short for Cluster Architecutre will give birth to not only a new 6 Series, but (for some reason) a 5 Series Gran Turismo and a Touring model, which won't likely be sold in the US. It will also underpin the 7 Series, eventually. Under hood, the lighter 5er will be paired with a new 1.5-liter, three-cylinder turbodiesel for the entry level 518d. This is the same three-pot oil-burner found in the 2 Series Active Tourer and Mini Cooper D. Of course, considering how little of BMW's actual engine range is sold in the US, we very much doubt the 518d will make it across the pond. More likely candidates for the US market include a range of a 2.0-liter, four-cylinders, such as the 272-horsepower 528i, and potentially a four-cylinder diesel. Naturally, there will be six-cylinder mills, found on the 530i, 530d, 540i and M550d. At the very top of the range, of course, will be a 600-hp M5. There will even be a range of hybrids and plug-in hybrids that are sure to further annihilate the formerly logical BMW nomenclature. Car expects the new 5er to arrive next summer, which we'd wager would lead to a debut at either the 2016 Geneva Motor Show or perhaps next year's Auto China, in Beijing.
