Watch Atieva's electric van outrun a BMW i8 and Dodge Viper

A little while back, automotive startup Atieva drag raced its electric van, called Edna, against a Tesla Model S and a Ferrari California in order to compare its performance against known and revered mechanical athletes. Again, the Silicon Valley-based company is putting its prototype up against electrified and conventionally powered performance vehicles on the drag strip. Last time around, Edna, the Mercedes-Benz Vito van equipped with a 900-horsepower, all-wheel-drive powertrain, bested both of its foes. In that showcase, Edna was hitting 60 mph in a little over three seconds. Comparatively, BMW lists the i8's 0-60 time at 4.2 seconds, though Road & Track clocked it at 3.8 seconds, with a quarter-mile time of 12.3 seconds. The Viper does 0-60 in 3.4 seconds. Before you even watch the video above, you can imagine how it will end, as the retuned Atieva Edna rips 0-60 mph in 2.94 seconds. Atieva clocked the quarter mile at 11.3 seconds at 117 mph. It's worth noting that driver skill can have a lot to do with a car's straight-line performance. We've witnessed Viper's elapsing the quarter mile in well under 12 seconds, which means it should be quicker in this test than the i8, if not the Edna. Still, the performance showcased in the video is exceptional. To improve Edna's stats, Atieva says it has used testing data to fine tune its AC induction motors at higher speeds once it got low-speed performance locked in. After testing in the hot California sun, including the race you see above, Atieva drove Edna 90 miles home with range to spare. As for production plans, Atieva will put this powertrain into a sedan slated for sale in 2018. In the meantime, the company will keep testing and tuning its working prototype, and has even invited the public to put their cars up against Edna in future sessions.

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 M models will stay rear-wheel drive as long as possible

Don't expect BMW's M cars to go soft any time soon. Carsten Pries, the division's head of product management, wants to focus on at least six cylinders and rear-wheel drive for as long as possible. Pries sees the combination of six (or more) cylinders and rear-wheel drive as defining features of the division. "These are cars that attract new people to the M brand and that is very important," he said to Motoring. He doesn't think it's time to deviate from that strategy yet. "I hope not, because six is part of our DNA. Not only the power, but that hallmark sound that we have." We certainly like Pries' sentiment, but the division's current lineup shows a willingness to compromise the purely rear-wheel drive focus when necessary. For example, the latest X5 M and X6 M already feature all-wheel drive systems, which can send 100 percent of the power to the back at times. Spy shots and rumors heavily suggest a similar option for the next-generation M5, too. The latest M4 GTS proves BMW knows how to tune a fantastic sounding six-cylinder, but there's no reason a well engineered four-cylinder model couldn't be great. The original M3 relied on one to speed around, and it became a performance icon of its period. Pries even admitted in 2014 that a new four-cylinder M vehicle could happen eventually. For now, he isn't ready to introduce a new four-pot model. Pries admits that the division's strategy might need to change someday, but he still expects to create M-badged models. "If the framework changes in the future, we have to look then at what we can do in terms of a proper or decent M offer," he said to Motoring. Related Video:
