2015 Audi A3 TDI Challenge

I officially gave up after 758 miles. The 15 or so miles leading up to this decision were spent in the right lane of Southern California's I-8 freeway, hazard lights blinking, climbing uphill at just over 40 miles per hour. After two days of sweating to the oldies (okay, a mix of SiriusXM Classic Rewind and First Wave), I had covered those 758 miles in a 2015 Audi A3 TDI on one tank of diesel fuel. And when I say sweating, I mean it quite literally. In order to maximize fuel efficiency, my co-driver and I kept the air conditioning off, even when the direct sunlight in the California desert had outside temperatures hovering around 90 degrees. I had been doing this hypermiling exercise for two days, the car was getting stinky, and I was ready to hear the sweet "thhhhhhhwack" of satisfaction that would finally come from peeling my sweat-soaked self off the A3's leather seat. Sexy, I know.
Audi had challenged me to drive 834 miles from Albuquerque, NM to San Diego, CA, on just one 13.2-gallon tank of diesel fuel. If you believe the EPA's highway fuel economy rating of 43 miles per gallon, this means I should have sputtered to a stop after 568 miles. But I went a grand total of 758 - that's 59.4 mpg - and I could have kept going. In fact, two teams made it the full 834 miles on their one allotted tank of fuel. That's over 63 mpg. That's twenty miles per gallon better than EPA estimates.
The TDI Challenge took me through three states over the course of two days, and the 834-mile journey wasn't just a simple highway cruise. I negotiated uphill climbs, long series of involving switchbacks through the mountains and elevations that ranged from 220 feet below sea level to nearly 8,000 feet above. I learned that super-crazy-efficient driving like this an incredibly challenging game that takes serious skill. But I also learned that if you're going to attempt to stomp all over the EPA's numbers, the Audi A3 TDI is one heck of a car for the journey.

Audi CEO's Dieselgate arrest threatens fragile truce among VW stakeholders

FRANKFURT — The arrest and detention of Audi's chief executive forces Volkswagen Group's competing stakeholders to renegotiate the delicate balance of power that has helped keep Audi CEO Rupert Stadler in office. Volkswagen's directors are discussing how to run Audi, its most profitable division, following the arrest of the brand's long-time boss on Monday as part of Germany's investigations into the carmaker's emissions cheating scandal. The supervisory board of Audi, meanwhile, has suspended Stadler and appointed Dutchman Bram Schot as an interim replacement, a source familiar with the matter said on Tuesday. Schot joined the Volkswagen Group in 2011 after having worked as president and CEO of Mercedes-Benz Italia. He has been Audi's board member for sales and marketing since last September. The discussions risk reigniting tensions among VW's controlling Piech and Porsche families, its powerful labor representatives and its home region of Lower Saxony. VW has insisted the development of illegal software, also known as "defeat devices," installed in millions of cars was the work of low-level employees, and that no management board members were involved. U.S. prosecutors have challenged this by indicting VW's former chief executive Martin Winterkorn. Stadler's arrest raises further questions. Audi and VW said on Monday that Stadler was presumed innocent unless proved otherwise. Munich prosecutors detained Stadler to prevent him from obstructing a probe into Audi's emissions cheating, they said on Monday. Stadler is being investigated for suspected fraud and false advertising. Here are the main factors deciding the fate of Audi. Background: Audi's role in Dieselgate Volkswagen Group was plunged into crisis in 2015 after U.S. regulators found Europe's biggest carmaker had equipped cars with software to cheat emissions tests on diesel engines. The technique of using software to detect a pollution test procedure, and to increase the effectiveness of emissions filters to mask pollution levels only during tests, was first developed at Audi. "In designing the defeat device, VW engineers borrowed the original concept of the dual-mode, emissions cycle-beating software from Audi," VW said in its plea agreement with U.S. authorities in January 2017, in which the company agreed to pay a $4.3 billion fine to reach a settlement with U.S. regulators.

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.
