The 2014 Rolex 24 at Daytona: What we learned, what we saw

Two days after the flag dropped on the 2014 Rolex 24 at Daytona, people are still trying to figure out what it might portend for the rest of the season. In 24 hours, two minutes and 24 seconds, 695 laps were completed by the car that crossed the line first. During that time, 67 cars began the race, 18 of them retired. There was that accident, and a red flag. There were supposedly slower classes beating supposedly faster classes. There were 16 caution periods, including that yellow flag. And then there was The Decision. And Then The Uproar. And then The Reversal.
There was also some pretty good racing, so let's have one last look at the weekend. Oh, and there was that 1964 Ferrari 250 GTO Series II...
If you want to skip the reading bits and go to the photos, there's a high-res gallery of 158 images above and a couple more below. Enjoy.

Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

1,682 miles in a 2014 Audi A8 L TDI - Part 2

Interruptions like the Canadian Grand Prix, Le Mans, Pikes Peak, that ridiculous Porsche 911 GT3 and the really good, really outrageous Jeep Cherokee, are among the distractions that delayed the conclusion of this tale. If you'll remember, in Part 1 we started off in a parking lot in Sebring with an Audi A8, headed anywhere that would empty our tank, and after five days in Miami and Ft. Lauderdale and Pompano Beach we bolted in the middle of the night for a breakfast date at an IHOP a couple hundred miles away.
We last left proceedings at a Chevron pump beside the West Florida Turnpike, somewhere around midnight in the humid wilds, having done 660 miles and spent $89.40 to put 20.992 gallons in the great white whale. We had done average speed of 31 miles per hour at an average rate of 27.5 miles per gallon. Those kinds of numbers, as we demonstrated, are good enough to put you in the fuel economy orbit of the Toyota Corolla - to be precise, it only cost $6.40 more to cover that 660 miles in the A8 TDI than it would in the Japanese compact. That led us to conclude that there were just a couple of Starbucks Venti lattes between the A8 and the Corolla, assuming we conveniently ignore the two cars' purchase prices. Turns out we were wrong: it didn't take long for a commenter named "mike" to set us straight when he wrote, "It's clear you weren't lying about not frequenting Starbucks...no way could you get two venti lattes for $6.40." Mike, we salute you - our ignorance of terrible coffee has served the higher purpose of emphasizing the strong case made by the diesel Audi.
But that A8... well, the wheels were still on the damn thing and we had to drive them off. That meant five more days of pilot duty to get us from wherever the hell we were to Wildwood and Daytona Beach, FL, then Brunswick, Macon and Atlanta, GA, then Birmingham, AL, and back to Atlanta.
