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 supercar not yet approved, R4 not quite dead, still room for an MPV

According to a report by Autocar, all we thought we knew of the in-development Audi supercar we might not actually know. A piece in Car and Driver, not even a month old, said the diesel-hybrid halo car was in the design stages, would get the engine from the R18 E-Tron Quattro and its carbon fiber tub. Now we get word that that while the coupe is indeed being designed, it hasn't yet been signed off and there's no business case for it yet. Said business case, whenever it is built, is also dubious of the diesel aspect of the car at the moment - diesels aren't known for creating Pavlovian purchase responses in buyers in the two key markets of the US and China.
The report suggests that instead of a diesel, the 2014 Le Mans regulations changes "could swing the favour back towards petrol models," which would give the so-called Scorpion a better tie to racing technology. Of course, that also assumes that Audi would contest next year's Le Mans with a gas-powered car. If so, that would be an about-face on the original reasons for the halo sportscar in the first place.
In other news, seems Audi also believes it can slot another sportscar below the R8, it just needs to get the financials sorted. The R4 - a Porsche Boxster-sized roadster - that has been chattered about for years is still in on the table but appears a long way off. Company R&D chief Wolfgang Durheimer said it would need to be mid-engined and bring plenty of tech to separate itself from the TT, but mass-market price point is the catch as is the focus on other segments in the portfolio.

Overnight action from the 24 Hours of Le Mans

We won't go into a recap here, but there are still leading positions being fought for in all classes - it's so close that leads are changing when a car goes into the pits. We'll let the recap wait until the end of the race, so for now enjoy some shots from last night's action at the 24 Hours of Le Mans.
