Notes from Day One of the 2013 Twelve Hours of Sebring

The 61st edition of The 12 Hours of Sebring is on, and Autoblog has come to central Florida with Audi to feast on jumbo boiled peanuts, pickled eggs and the final race for the LMP1 class at the oldest road course in North America. As Audi has been doing for more than a decade now, it's brought its latest endurance race car, the 2013-spec R18 etron quattro, to Sebring to begin testing for Le Mans.
Why the commitment to Sebring? Audi Sport executives have repeatedly called Sebring "punishing," "extremely demanding" and "one of the toughest tracks in the world." It is a 3.47-mile circuit that, in places, feels like it was made from the leftover bits of other circuits. Doing the 12-hour distance in Florida is thought to be a good start on lasting the 24-hour distance in France, and we can't think it a coincidence that Audi has won ten times here in the last 13 years and 11 times in Gaul.
Where there's rhyme - and victory - there is reason. We think we found a few of them on our first day where preparation, technology, fastidious attention to detail and sweat fit right in with swamp cabbage...

Next Audi Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.
