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.

CO2-neutral* Audi A3 G-Tron goes on sale in Germany

The Audi A3 Sportback G-Tron has been on our natural gas-powered radar since it was unveiled at last year's Geneva Motor Show. Just before the big show starts up again this year, Audi put the new G-Tron vehicle on sale in Germany today, starting at 25,900 euros ($35,400 US). Anyone who opts for the Audi e-gas fuel card will be able to cruise the Autobahn knowing that their emissions will be CO2-neutral. That's because Audi has built an e-gas plant in Werlte in Lower Saxony, Germany that creates a synthetic methane that is compatible with natural gas from a process that uses "green electricity" to "[bind] as much CO2 as is released when the Audi A3 g-tron is driven in gas mode." Your own A3 G-Tron doesn't burn the carbon-neutral fuel directly, but the automaker will track how much is spent using the fuel card and make sure "that exactly this amount of Audi e-gas is fed into the German natural gas network." Audi charges 14.95 euros a month to use the card. Burning that e-gas in the A3's 1.4-liter TFSI engine can put out 110 horsepower (you can also burn regular natural gas or gasoline) and offers fuel economy of between 3.2 and 3.3 kilograms of gas per 100 kilometers on natural gas Audi A3 g-tron: Advance sales get the green light Ingolstadt, 2014-02-13 Audi A3 Sportback g-tron available to order from February 13 CO2-neutral mobility with the Audi e-gas fuel card Prof. Dr. Ulrich Hackenberg: "Audi e-gas is an important pillar of our sustainability strategy" The Audi A3 g-tron is all set to hit the roads. Advance sales at dealerships in Germany will kick off on February 13. The basic price will be 25,900 euros. Using the Audi e-gas fuel card, customers can opt for Audi e-gas to power their A3 g-tron without impacting the environment if they wish. The Audi A3 g-tron forms part of a new, integrated and sustainable mobility concept from the brand with the four rings. Its 1.4-liter TFSI engine developing 81 kW (110 hp) can be operated using either natural gas, e-gas generated by Audi or gasoline. In pure e-gas mode the g-tron is entirely CO2-neutral. Audi e-gas is a synthetic methane that is produced at the Audi e-gas facility located in Werlte in Lower Saxony, Germany – the world's first industrial power-to-gas plant. An A3 Sportback g-tron fueled by Audi e-gas is currently the most environmentally friendly form of long-distance mobility.

US-bound Audi A3 Sedan spied testing

As the Audi A3 sedan gets closer to its debut, Audi has camouflaged prototypes to take it on the streets for final testing. Last time we saw the A3, it was testing almost in the buff, but it was on a closed track so our spy shooters were kept at quite a distance.
Now that the newest Audi sedan is testing on public roads, our latest batch of spy shots gives us a more detailed look at the entry-level luxury player despite the swirly camo. Except for the oversized wheels and the fancy exhaust outlets and door mirrors, the production version of the car should look almost identical to the A3 sedan concept we saw in Geneva a couple years ago. Some of the details we can see include a good-sized panoramic roof that stretches almost halfway into the rear passenger space and signature Audi LED-accented headlights and taillights.
