Tech Talk: Comparing Loop Data To Analyze The Gen-6

_Author's Note: An unexpected scheduling conflict caused our crew chief to be unavailable this week, so we're going to take a look at the loop data statistics from last year's Phoenix race vs. this year's to see what the performance of the Gen-6 vs. COT looks like from a purely data-driven perspective._ NASCAR compiles a mountain of statistics each week that allow digit heads across the land, and in the garage area, to make unbiased comparisons on many different levels. Since Sunday's race was the first unrestricted event for the latest version of the Cup Series car, it just might be interesting to see what the numbers reveal. The first numbers we'll look at are quality passes. A quality pass is one that occurs on a car running in the top 15 under green flag conditions. In last year's race, Jimmie Johnson finished fourth but had the most quality passes during the race with 63. Interestingly, in 2013, Brad Keselowski finished fourth and also had the most quality passes; however, the defending champion only notched 35 of them. In looking at the quality passes, the top 11 passers in 2012's Spring Phoenix race made more than the top passer in 2013. That's sign that to pass someone, last Sunday it was far more difficult than during the race a year before. <div style=\"float:right; width:275px; margin: 20px; border: black solid 1px; padding: 3px;\"><img src=\"http://www.frontstretch.com/images/15503.jpg\" width=\"275\" height=\"102\"/><p style=\"margin: 3px; text-align: left; font-weight:bold;\">Much has been said of the Gen-6 cars leading into the 2013 season, but are they really that much better than the COT was?</p></div> Next up is the speed in traffic stat. It gives you the average speed of the driver when he has another car within one car length of them during green flag laps. This year's top runner at Phoenix was Matt Kenseth with a speed of 129.807 mph. Last year's best in traffic was Jimmie Johnson who clocked 130.260 mph. When it was all said and done, the speed of the top runners was nearly identical from one year to the next. Third up is the statistic that backs up the argument that you always hear from the people who attend the race in person. They always maintain that there is so much more action back in the pack than what you see on TV. Green flag passes will most definitely let you know which race had the most excitement from front to back of the pack. In 2012, Jimmie Johnson once again led the category with no less than 90 passes during green flag competition. That was nearly 50% more than this year's king of the overtake, AJ Allmendinger, who put the move on 61 cars throughout the length of the race. The top 12 drivers in the 2012 green flag pass statistics made more green flag passes than the top passer in 2013. Laps led is another category that indicates the competitive nature of a race. More drivers leading laps means more drivers were at the front. Certainly some laps led occur when drivers stay out during cautions, but in the long run, more drivers leading laps indicates more competitive races. 2013 saw nine drivers lead laps, with five of them leading double digit laps and Carl Edwards leading the most at 122 circuits. In comparison, 2012 saw 15 drivers lead the field across the line, but only five of them led double digit laps. The mandate that came down from above as the manufacturers and NASCAR's R&D center started working on the latest edition of the Cup series car was to have more side-by-side racing and more passes for the lead. While there is a long way to go and many things to be learned about this new car, for now it is looking like the older car was a bit more competitive. However, the older car had been around for six years, and there had been a lot of tricks and techniques learned to make it better. For now, the jury is still out on the new car. But, looking at the numbers that were accumulated last Sunday, the older car was faster, had more passing and more leaders. We'll see what it looks like when the series rolls back into Phoenix in November. *Connect with Mike!* <a href=\"http://www.twitter.com/mneffshorttrack\"><img src=\"http://www.frontstretch.com/images/6502.jpg\"></a><br> \"Contact Mike Neff\":http://www.frontstretch.com/contact/14354/

Thinkin’ Out Loud: 2013 Sprint Unlimited at Daytona

On lap 16, Tony Stewart attempted to change lanes and make a move on race leader Matt Kenseth. While he wasn’t cleared by his spotter, Stewart chose to shift down low which resulted in his left rear corner making contact with the right front of Marcos Ambrose. Stewart’s car got out of shape, made contact with the apron and sent a shower of sparks over several cars that were pursuing him. Jimmie Johnson checked up in the high line, which caused Denny Hamlin to make contact with the five-time champ, turning him down in front of the oncoming pack and ultimately taking out one-third of the field. The accident eliminated defending champion Kyle Busch, two-time Unlimited champion Jeff Gordon, 2006 winner Denny Hamlin and 1999 winner Mark Martin. Just like that, the field was reduced by one-third, many contenders sat idle in the garage and the drafting – along with the racing – became a shell of its former self.

Thinkin’ Out Loud: 2012 AdvoCare 500 at Phoenix

Jeff Gordon intentionally wrecked Clint Bowyer, collecting Joey Logano and Aric Almirola as the field was coming to the white flag. The result was a green-white-checkered finish, one that saw Danica Patrick wreck on the first of two laps, lay down a large amount of oil on the track, then cause a complete melee on the front straight as the cars came to the checkered flag. The final wreck tore up over half-a-dozen race cars while the incident between Gordon and Bowyer set off a rumble in the garage, one reminiscent of the Tide team vs. the Kodiak crew at the 1989 Winston.

Thinkin’ Out Loud: 2012 AAA Texas 500

During the seventh caution flag of the night, Brad Keselowski took two tires on his pit stop to regain lost track position while Jimmie Johnson and Kyle Busch took four. That got Kes the lead, for a series of restarts but kept what was likely the fastest car from having the speed to pull away. While Busch faded into the background, that decision would ultimately result in Johnson and Keselowski finishing first and second.

Thinkin’ Out Loud: 2012 Tums Fast Relief 500 at Martinsville

During the pit stops for a lap 476 caution, Brad Keselowski and Dale Earnhardt Jr. stayed out while Jimmie Johnson, Jeff Gordon, and the rest of the lead lap cars came in for two tires. Johnson restarted behind Keselowski and worked him over for four laps before taking the lead for good. In the end, Keselowski ended up about where he would have finished with tires, while some of the other top contenders on the day ended up falling back to unsatisfying results.
