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 creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.

Recharge Wrap-up: Smart metals, OTA updates, Rolls-Royce LNG ship

"Smart" metals could help engines reduce emissions and invigorate US business. Metallurgist and University of Wisconsin – Milwaukee professor Pradeep Rohatgi combines known metal alloys with materials like ceramics, nanoparticles, and recycled waste to produce strong, lightweight composites with self-lubricating properties that help internal combustion engines run more efficiently. Rohatgi hopes his startup, Intelligent Composites, and its products can help US foundries compete with production outsourced overseas. See the video above, and read more at Phys.org. Almost 203 million cars will be capable of over-the-air (OTA) updates by 2022, according to ABI research. While Tesla has the OTA firmware updates nailed down, other automakers will focus on software update capability. This will take the place of dealer-installed updates and - like Chrysler did after the Jeep hacking incident - updates sent to owners via USB drives. OTA updates will enhance vehicle security and reduce recall rates. Read more at Green Car Congress. European bus manufacturers have agreed upon a standardized charging interface for their electric buses. Irizar, Solaris, VDL and Volvo will use pantograph charging for "opportunity charging" and CCS plugs as the base for overnight charging and network communication. The manufacturers hope other bus makers and charging providers to join them in cooperation over standardized charging. Read more at Green Car Congress. The second Audi Autonomous Driving Cup will take place from March 22 to 24, 2016 at the automaker's Museum Mobile in Ingolstadt, Germany. The competition involves eight university teams implementing basic Audi software in 1:8 scale electric Audi Q5 models, and putting them through the paces of simulated real-world driving situations. The teams develop software architecture to use the suite of sensor to have the cars drive, park, maneuver in traffic and perform emergency braking autonomously. Teams also perform a freestyle event where they put the car through an additional task of their choosing. The winning team gets ˆ10,000, with smaller prizes for second and third place. The competition also gives the students the opportunity to showcase their skills in front of a potential employer. Read more at Green Car Congress. Rolls-Royce will provide the Liquefied Natural Gas (LNG) propulsion for an NSK cargo ship carrying fish food. The ship will deliver 2,700 metric tons of fish food to fish farms along the Norwegian coast.
