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:

Audi RS3 spy shots foreshadow an ultra-hot hatch

Not all vehicle prototypes and mules require heavy camouflage - sometimes they can be hidden in plain sight. That's probably what Audi was hoping for while testing its new RS3 wearing S3 duds, but thanks to some visual and audible telltales, our spy photographers were able to recognize this as a precursor to the marque's ultra-hot hatch testing near the Nürburgring.
Our photographer noticed the signature exhaust note of a five-cylinder engine, which suggests the RS3 could borrow its motivation from the excellent TT RS. Producing at least 340 horsepower, this 2.5-liter turbo powerplant could be the perfect answer for the new A45 AMG from Mercedes-Benz. The big brakes on this RS3 mule give us our best idea about the car's high-performance intentions, with Audi RS wave brake rotors and six-piston calipers peering out from behind the oversized wheels.
In production form, the RS3 should have a much different appearance from what you see here, with sportier design cues including oval-shaped dual exhaust outlets and a more aggressive front fascia. While we're still waiting for our first taste of the S3 in the North America, we'll be holding our breath for the RS3 to make its way here, as well.

Audi to launch 600-hp RS6 Avant Plus?

Much to the dismay of many - but apparently not enough - there's a whole category of power wagons available overseas that we just can't get our hands on. While the Mercedes-Benz E63 AMG Estate and Cadillac CTS-V Sport Wagon are both available Stateside, the recently revised Mercedes-Benz CLS63 AMG Shooting Brake, the Jaguar XFR-S Sportbrake we recently drove at the Nürburgring and the Audi RS6 Avant remain out of reach for American buyers. They all stand on more-or-less equal footing, with forced-induction V8s producing around 550 horsepower. But Audi is apparently taking things over and above with a new RS6 Plus.
Revealed ahead of schedule on a British dealer's website (which leaked details accompanied by a stock photo of the existing model), the RS6 Avant Plus will apparently keep the same 4.0-liter twin-turbo V8, but upgrade from 560 hp to a nice, round 600 to put it ahead of the competition and in league with supercars. Considering that the existing RS6 Avant is already capable of cracking the four-second barrier to 60 and tops out at over 190 miles per hour, we're sure the Plus version will positively annihilate the Autobahn, all while bringing your whole family along for the ride.
Unfortunately it doesn't look any more likely that Quattro GmbH's latest Plus model will make the transatlantic journey to American showrooms, but we can hope that maybe Audi will perform similar modifications on the RS7 Sportback we do get here.
