Porsche 911 Turbo and Nissan GT-R Nismo star in World's Greatest Drag Race 4

We love Motor Trend's annual World's Greatest Drag Race video. Now back for its fourth appearance, the idea of lining some of the world's fastest cars up for a ten-wide, straight-line, full-throttle run is, well... it's pretty freaking badass.
The lineup this year boasts some impressively fast cars to be sure. The group of ten includes the following darlings: Alfa Romeo 4C, BMW i8, BMW M4, Chevrolet Camaro Z/28, Ford Fiesta ST, Jaguar F-Type R Coupe, Nissan GT-R Nismo, Porsche 911 Turbo S, Subaru WRX STI and, last but not least, the Volkswagen GTI. Give us any one of those for the weekend, and we're happy to take the keys.
It must be said though, that for a publication that draws as much water as Motor Trend does, there are some big cars that we might expect to be here instead. The Lamborghini Huracán or Ferrari 458 Speciale would have added some exotic flare to the list, and the omissions of the Chevy Corvette Stingray (for the second year in a row) and the Dodge Challenger Hellcat are real head-scratchers.

BMW i5 could be a new kind of i PHEV

Just this month BMW North America CEO Ludwig Willisch made a point of saying "Not any time soon" to AutoblogGreen's question about the arrival of a BMW i5 - and that came after he clarified, in case we didn't know it, that no such model exists. But the rumors of its eventual appearance were swelled again by a report in Autobild that sticks more details and numbers on what could be the next offering in for the i brand. In February, Car magazine laid the i5 out as having a 245-horsepower four-cylinder engine in front, assisted by a 204-hp e-motor in the bow and a 90-hp e-motor in the stern, for about 544 total horsepower. Autobild claims the gas engine will have 218 hp, the front e-motor will have 150 hp and the rear will have 272 hp, for roughly 640 total horsepower. Where the two reports agree is that it - maybe called i5, maybe i7 - will be based on the China-market long-wheelbase 5 Series platform, it will incorporate cues from both the 7 Series and 6 Series Gran Coupe, and it will not be cheap: 100,000 euros ($105,686 US) is the estimate. The i8 starts at 130,000 euros in Germany. Weight for the i5 is figured to be around 3,300 pounds. Green Car Reports says what's important about the i5's drivetrain is that it's being maximized for electric running. Its evolution of the company's eDrive mechanicals will crank the ICE over only above 36 miles per hour, and even then, only in cases of "maximum power demand." Electric-only driving would offer a range of 78 miles, company officials suggesting that it could remain in that mode for "fully two-thirds of its usage cycle." Whenever a vehicle like this arrives, that is, which Autobild says could be in 2019.

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.
