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 A3 outselling Mercedes CLA 2 to 1 in its first 3 months on sale

The Audi A3 is on fire in US showrooms. Not literally of course, that would be horrible, and the situation we're referring to is a good thing indeed, as the Four Rings has a serious hit on its hands with the compact luxury sedan. Looking at just its first three months on the market, the entry-level model is outselling the Mercedes-Benz CLA-Class by nearly two to one.
The CLA was one of the hottest new cars of last year. Mercedes even called it the company's best launch in 20 years, but it sees as if that early sales performance has not been sustainable. According to Bloomberg, the CLA has seen its sales drop year-over-year in seven of the last eight months, and the new A3 came at just the right time to fill that void.
In June, Mercedes shifted 1,658 CLAs in the US, compared to 2,452 for the A3. The Merc has sold more units so far this year but only because the Audi sedan has only been on sale for three full months. With the two cars being relatively comparable as compact, front-wheel-drive, German luxury sedans, it appears buyers prefer the Four Rings over the Mercedes star, so far at least.

Entry-level Audi R8 to go turbo after all?

Would you be shocked if we told you that the better version of the Audi R8 offered a V8 engine rather than a V10? There was something inherently lovable about the company's 4.2-liter V8. Maybe it was the noise or the high-revving nature or some combination of the two, but the R8's original engine is a darn hoot. Sadly, the V8's days appear numbered in the brand's flagship model, according to a new report from Car, which claims Audi will ditch the beloved, off-angle 4.2-liter for a 2.9-liter, twin-turbocharged V6. The rumor cites sources in Ingolstadt who claim the new engine will develop 450 horsepower, up 20 ponies on the current entry level engine. We'd expect a commensurate increase in fuel economy too, befitting of a smaller, force-induced engine. Still, this is counter to what we've heard before. But, if the report proves true, the R8 will join the ranks of turbocharged supercars like the Ferrari 488 GTB and California. It's unclear when such a switch would be made, but according to Car, we can place the blame squarely on China. The country has been combating large-displacement engines since 2008, attaching massive taxes on vehicles with anything larger than a 3.0-liter engine. It's China's position, Car reports, that led to the death of another beloved, naturally aspirated V8, Mercedes-AMG's 6.2-liter model. First the venerable M156 and now Audi's 4.2-liter V8? Just stop this silliness China. Related Video:
