2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

Lots of new cars were unveiled in Munich this week. Here's what you might've missed

The 2021 Munich Auto Show is happening this week and due to ongoing corporate travel restrictions, we remained firmly planted on this continent. So, although we can't tell you exactly what it's like inside the futuristic new Mercedes EQE electric sedan or fully appreciate the funky Volkswagen ID.Life concept, there's no shortage of details and analysis to provide.  Obviously, as Germany's premier auto show in 2021, the cars unveiled were primarily from the German brands. We also focused mostly on the cars that might actually make their way to the United States, or at least inspire those that will.   2023 Mercedes-Benz EQE is an electric alternative to the E-Class While the EQS paved the way for Mercedes' electrified future, much like the S-Class before it, the EQE stands to be the car that will move in far greater numbers -- much like the E-Class before it.

Though perhaps a tad derivative of the Honda E, Volkswagen's blocky little crossover EV nevertheless represents a handsome new direction for VW design. We like this better than the rounded looks of the current ID.3 and ID.4.  2021 Volkswagen ID.Life concept View 20 Photos   BMW i Vision Circular is a 100% recycled and recyclable hatch Behold, the next BMW 3 Series! Just kidding. Besides this, BMW displayed cars in person for the first time that it had previously only unveiled on the interwebs, including the new 2 Series and revised iX3. It also unveiled some bikes. BMW i Vision Circular Concept View 63 Photos   Audi's GrandSphere concept was designed as a road-going private jet Does Audi know what a sphere is? Cause this isn't anything like one. Still, it's quite a handsome thing, and as one of three Sphere-branded concepts, previews the next direction of Audi design (which is pleasantly reminiscent of two-decade-old Mazda design). No complaints here. 2021 Audi GrandSphere concept View 26 Photos   Porsche Mission R is a 1,000-horsepower electric monster Just like the Mission E previewed the Taycan, this apparently previews another future car.

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.
