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.

What the Volkswagen I.D. concept tells us about the post-TDI future

If you've been paying attention, 2016 hasn't been a great year for Volkswagen. The TDI scandal removed VW's last crutch between our internal combustion present and the electric future, and so the company found itself scrambling to shift resources to show what's next right now. It's naive to assume that this is truly the sort of fairytale comeback story that VW's spin doctors would have us all believe, but it's notable that instead of flinching or pointing fingers, the engineers got to work. What they've produced is the I.D. concept, the third wave in VW's volume car history after the Beetle and Golf. The transaxle Golf was more than simply an updated Beetle, and likewise the I.D. is more than an electrified Golf. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. VW says the I.D. won't replace the Golf, but they said the same thing about that car replacing the Beetle. It's only a matter of time. The I.D. approach is refreshingly simple: no carbon fiber chassis, no exotic battery chemistry, no outrageous concept car styling. The MEB chassis (the German acronym for modular electric platform) is made out of a traditional mix of high-strength steel grades to save costs and utilize existing factories. The battery is integral, not swappable, to reduce complexity and increase structural rigidity. It's also uses lithium-ion chemistry because of a proven track record and an existing (albeit deficient) supply chain. Contrast that with the e-Golf, which shares its chassis with the conventional internal-combustion cars. Fitting the battery and its ancillary systems became complicated and expensive. The skateboard installation in the I.D. will allow the pack to be optimized for the space available, reducing costs. As we've already reported, MEB will be shared across all VW Group brands to achieve an economy of scale, and the modular platform can be stretched to the size of roughly a Passat and down to a car slightly smaller than the I.D. It can be given all-wheel drive, although VW's e-mobility chief Christian Senger is quick to point out that the standard rear-drive configuration provides plenty of traction because of optimal weight distribution achieved with battery in the middle of the chassis. It makes all-wheel drive more of a bonus rather than a necessity in bad weather.

Audi execs mulling turbocharged, entry-level R8

The just-launched, second-generation Audi R8 is apparently a pretty fantastic example of Vorsprung durch Technik. While it's sublime to drive, Audi might already be missing some potential sales due to the lack of an true entry-level version in the supercar's lineup. Lending further credence to an earlier rumor about just such a model, company execs are saying to expect an entry-level, turbocharged R8 to launch in the coming years. "It is inevitable that we will go to a turbocharged motor for it at some point," Audi technical development board member Dr. Ulrich Hackenberg said to Motoring. "It would be in this model cycle, to give us a fuller range." The executive certainly isn't mincing words about forced induction, but the V10's position in the lineup is also secure. "It doesn't mean we are not going to do a turbo, but naturally aspirated is here to stay as well," he said. If Dr. Hackenberg's direct assertion isn't enough, Quattro GmbH chief Heinz Peter Hollerweger further clarified to Motoring that the turbocharged engine would slot into the bottom of the R8's range. An unnamed "senior sales and marketing source" within the Audi also said that the company's turbo five-cylinder was among the currently favored choices for the application. The first rumors about the R8 getting a forced induction version arose just a few months ago. At the time, Audi's electrically turbocharged, 2.5-liter inline five-cylinder was considered an option. The model would solve a problem in markets, like China, that severely tax big displacement engines. Customers might not even need to worry about giving up too much performance either. In the Audi TT Clubsport Turbo concept, the powerplant has a total output of 600 horsepower and 479 pound-feet of torque. While 10 fewer ponies than the latest R8 V10 Plus, it would bring 66 lb-ft more twist to the supercar.
