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 celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

Audi bringing TT Clubsport Turbo concept to Worthersee

Is the world ready for an Audi TT with 600 horsepower? Well it had better be, because that's exactly what Ingolstadt has in store for this year's GTI-Treffen at Worthersee, Austria. Billed as a "technology concept," this TT show car packs a 2.5-liter inline-five with two electric turbochargers. Audi is developing electric turbos for its diesel engines, but has found a performance application here in a gasoline engine. The result is a whopping 600 horsepower and 479 pound-feet of torque, driving all four wheels through a six-speed manual transmission. Weighing in at 3,078 pounds and with those electric turbos spooling up quick, it's said to reach 62 in 3.6 seconds en route to a top speed of over 192 miles per hour. In a TT. The turbos are powered by a 48-volt electrical system, juiced by a compact lithium-ion battery in the trunk that can store regenerated power. It's also got a coilover suspension and electric jack to get over obstacles like curbs and speed bumps. The whole thing rides on 20-inch alloys with a two-tone finish, with carbon-ceramic discs to keep it all in check, and as you can see, a rather aggressive-looking widebody aero kit. All of which makes for a rather stunning concept, even if its encroachment on the R8 means it will likely never see production.

From May 13 to 16, Audi will be showing its technology concept car on the Worthersee Tour in the Austrian town of Reifnitz. The inspiration for the show car came from the successful Audi 90 IMSA GTO of the late 1980s. A new technology is making its debut under the hood. The car's electric biturbo adds even more dynamism to the driving experience with its spontaneous response. "The electric biturbo signifies a new dimension in driving enjoyment; it boosts sprinting ability and torque and enables high peak power," explains Prof. Dr. Ulrich Hackenberg, Audi Board Member for Technical Development. "In our TDI engines, we are close to production readiness with this technology.
