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:

Felix Baumgartner parachutes into racing at N?rburgring 24

There are plenty of commonalities to be found between astronauts and racing drivers. Both are daredevils by definition (if not by trade), both subject themselves to unfathomable G forces and both face very real risks when strapped into machinery that makes the very best use of advanced propulsion, aerodynamics and composite construction technologies. Yet you don't find much crossover between the two. There was talk of Niki Lauda, himself an experienced pilot, training to go into space with Virgin Galactic (which itself was sister to an F1 team for a while in Richard Branson's empire), but that didn't seem to materialize. Now we're receiving news that Felix Baumgartner will contest the Nürburgring 24 Hours this year.
Felix Whomgartner, you ask? Felix Baumgartner. He's more of a skydiver than an astronaut, but he made history in 2012 when he jumped out of a space capsule and set the record for the highest altitude in a manned balloon, the parachute jump from the highest altitude, and the highest velocity freefall as part of the Red Bull Stratos initiative. In other words, he may as well be an astronaut, because he fell down to the earth's surface from the stratosphere.
For his next challenge, Baumgartner will be climbing into an Audi R8 LMS Ultra in an attempt to tackle the Nürburgring. Having contested a handful of spec races under the VW Group umbrella, he'll undertake several test sessions and practice races before the main event in June, in which he'll alternate behind the wheel with professional racing drivers Frank Biela, Marco Werner and Pierre Kaffer. The initiative is part of the Audi race experience program that allows gentleman racers to team up with seasoned pros to take part in real races. Baumgartner will undoubtedly prove its highest-profile participant.

2021 BMW M3 and M4 vs all the high-powered sport sedans and coupes

Should you have a found a way to get past that schnoz, you've probably digested some of the basic specs for the all-new 2021 BMW M3 sedan and M4 coupe specs. They're plenty impressive. There's also, basically, two sets of them thanks to the regular and Competition versions that differ in engine output and transmission type.  But how do they compare to other ultra sport sedans and coupes? Well, we were wondering that too, so we fired up the Autoblog Comparison Spreadsheet Generator 5000 (aka me chained to my computer in a dark basement).  Sadly, there are surprisingly few competitors for the 2021 BMW M3. Rival sedans include the Mercedes-AMG C 63 and the Alfa Romeo Giulia Quadrifoglio, along with the Audi RS 5 Sportback sedan/coupe/hatchback thing. There's no more Lexus IS F, the Cadillac CT4 Blackwing has yet to arrive and Jaguar doesn't offer a spicy XE R.  Happily, there are more coupe rivals for the 2021 BMW M4, including the two-door versions of the AMG and Audi as well as the Lexus RC F. I also included the Ford Shelby GT350 and Chevrolet Camaro SS 1LE. On paper, they align incredibly well. On the street and on a track, I can personally attest that these Americans are fully capable of keeping up and/or bettering the fancy-pants luxury brands (and let's not forget there are even more powerful, hardcore versions available). If they don't align in terms of price or prestige, whatever. OK, let's get to the spreadsheet. Let's start with the coupes and note that I didn't bother listing the dimensions for the M4 Competition and C 63 S as they are identical to their "lesser" siblings.  I won't bother burning words explaining what you can see on the chart. Instead, I'll point out a few things that stood out to me. First, BMW M comes awfully close to matching the output of AMG's twin-turbo V8 despite having two fewer cylinders. Similarly, Audi manages to better the 0-60 time of the M4 Competition and tie the C 63 S despite being WAY down on power. It's not like it weighs less. Magic? Second, and speaking of 0-60 times, remember the importance that transmission and drivetrain make with them. It's not just horsepower and torque. An automatic will be quicker and easier to launch than a manual, while all-wheel drive provides more instantaneous and beneficial grip.
