Notes and notations on the 2014 Rolex 24 at Daytona [w/video]

This year is the 52nd edition of the Daytona 24 Hours. The 2014 Rolex 24 at Daytona is also the first race of the year in the brand new TUDOR United SportsCar Championship (TUSCC) With the merger of the American Le Mans Series and Grand-Am Rolex Sports Car Series rewriting and revising the rules of American sports car racing right up until yesterday, we've made the journey to an intermittently wet and constantly freezing Daytona Beach, Florida with Audi to watch the new R8 LMS and every other competitor explore the limits of those rules on the track.
With a ton to cover - and a couple of videos below to watch, including some slo-mo qualifying footage and a hot lap in an R8 LMS - let's not waste time with chit-chat, eh?
Quick things to know about the classes and the leader-light system:

Stay in the house from the Audi R8 Emmy ad

Audi is sponsoring the Emmys again, and launching an ad alongside the awards show that features a family living in the middle of the desert simply to have an excuse to drive their R8s as much, and as fast, as possible. Which is crazy. Even crazier, you can live in the exact house from the ad for a few days as part of an airbnb promotion. The stay includes chauffeured transportation from Las Vegas McCarran airport, all meals prepared by a personal chef, and an R8 V10 Plus in the driveway available for driving. Did we mention it's a real house and not just an advertising prop? It is. The 1,200 square foot Rondolino Residence sits on 80 acres near Scotty's Junction, Nevada, just over 2 hours northwest of Las Vegas. Beginning September 18, seven three-night stays in October will become available - one booking opens up each day at 9 PM Eastern. The rate is listed at $610 per night, with the bookings running October 10th through November 1st. You can book the experience, or try, on the airbnb page. As for the ad, titled "Desolation," at first it seems like a entertaining jaunt about the lengths people will go to for an amazing driving experience. A deeper (and totally unreasonable - it's just an ad) analysis suggests some truly troubling things going on. For starters, the lackadaisical parents let the children taunt a poisonous scorpion. Will the isolated upbringing and history of cruelty towards animals produce a future serial killer? In our deranged version of this fictional universe, yes. Second, the R8 - spoiler alert, both R8s - get super dirty on the run to the corner store. A corner store, which, seemingly unequipped for coffee roasting nevertheless has fresh artisanal beans sold in half-pound bags. Lacking a bulk purchase option, the plot of the ad surely repeats itself several times a week. That sounds insane, but hey, it's all about the drive. And we do love the "Leadfoot Coffee" easter egg. But we digress. Where is the car wash that left the R8 clean before the drive through the desert? And where is the second R8 parked? The male protagonist clearly drives out of the garage from a position that doesn't leave room for the second car. We can only surmise that there is a underground component to the house in the ad. To be clear, we're still in fictional universe of this ad - the real Rondolino Residence, like the Alamo, lacks a basement.

166 MPGe diesel-electric Audi Q7 E-Tron Quattro gets real in Geneva

Despite some warnings that plug-in vehicles would not make a big impression in Geneva this year, the first big reveals from the Peace Capital are indeed PHEVs. For example, the diesel-electric Audi Q7 E-Tron Quattro, which right out of the gate comes at us with some impressive numbers: an all-electric range of 34 miles and the "potential" to hit 166 miles per gallon equivalent. Whatever scale Audi is rating the new Q7 PHEV on, 166 MPGe is a resounding success. As we might guess from the prototypes we've seen and hints we've had, the Q7 E-Tron Quattro is not some auto salon fantasy. The vehicle will go on sale at the end of this year, in the UK, at least. Availability in the rest of Europe and here in the US is likely but unspecified in the press materials we've seen so far. The real-world reality of the Q7 E-Tron Quattro means that specs like a 0-100 kilometers an hour (62 miles per hour) time of six seconds and a top speed of 225 kmh (139.8 mph), CO2 emissions of under 50 grams per kilometer and a total system torque output of 516.3 pound-feet should be ours to test in the not-too-distant future. This whole E-Tron program is turning out to be quite something. Who else is ready?

Making its world public debut at the Geneva Motor Show, the new Q7 e-tron quattro combines a frugal TDI engine with lithium-ion battery technology for a potential range of up to 876 miles and the ability to travel emission-free for over 34 miles on electric power alone, contributing to an official CO2 figure of less than 50 grams per kilometre. The Q7 e-tron quattro is the second Audi model with a powerful plug-in hybrid drive system.
