2015 BMW M3 squares off against Alpina D3 in gas vs. diesel throwdown

There was a time when diesel meant one of two things: This vehicle's owner either wants to save some money at the pump or needs to haul massive loads. It definitely did not mean that the owner of said machine wanted to drive fast, but that perception has slowly but surely been changing over the last several years, with automakers from Volkswagen and Ford to Audi and BMW offering spiced-up versions of their high-compression, turbocharged diesels.
It's that last automaker we mentioned that's the subject of the video you'll see down below. One bright-blue BMW M3 was procured by the Brits at Autocar, and it was lined up against a deep-black Alpina D3 (which we sadly can't buy in the US) in a spate of tests, including acceleration, stopping, sound and lap times on a closed circuit. The results, which we won't spoil for you, were enlightening, and were followed up by personal impressions from the man behind the wheel.
We know you're curious. All it takes to find out which of these 3.0-liter, twin-turbo-powered 3 Series variants came out on top is to scroll down below and watch. You know what to do.

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 Pininfarina Gran Lusso Coup'e bows at Villa d'Este

The first collaboration between BMW and Pininfarina is this blunt-force two-door called the BMW Pininfarini Gran Lusso Coupe revealed at the Concorso d'Eleganza Villa d'Este. Said to be the "interpretation of a luxurious BMW Coupé as seen through the eyes of Pininfarina," once you get past all of the design-speak, you can focus on the full-bodied and keen-edged missile sitting on 21-inch wheels.
The long wheelbase makes for short overhangs. Up front, BMW's design language gets scraped across a whetstone, everything getting sharper, including the usually round cat's eye headlights that have gone dihedral. Under the hood is a V12, behind the twin-kidney grille in matte-sheen aluminium and high-gloss black. The same aluminum treatment also backs the taillights, the lenses designed to let air flow through them.
Inside is room for four, a cockpit canted toward the driver, Foglizzo leather in black and Tobacco Brown, 48,000-year-old kauri wood from New Zealand, deep pile carpet on the floors, a patterned virgin wool headliner and an "oblong aperture in the roof liner" set off by white LEDs.
