Intractable (adjective): very tough or unattainable to regulate, handle or remedy.
NASCAR set a difficult aim in making an attempt to design a automobile able to working any monitor with minimal modifications at reasonable price. They need to be recommended for the try. However the twin constraints of most versatility and minimal price are unattainable to concurrently fulfill.
NASCAR, well-known for making packing containers, have made a field they seemingly can’t escape. They took on a tough — maybe intractable — drawback. They haven’t been capable of remedy it. However IndyCar and Method One have the identical challenges and neither has arrived at an ideal reply, both.
NASCAR’s first try at a common race automobile was the Gen-5 (Automotive of Tomorrow), which launched a spec chassis that incorporated cutting-edge safety research. The automobile was not well received, partially as a result of NASCAR imposed the automobile on groups with out asking for enter, and partially as a result of it was generically homely.
The Gen-6 automobile retained Gen-5’s security advances and added producer id, balancing aerodynamics amongst completely different makes to make sure a degree taking part in discipline. NASCAR continued to experiment with comparatively easy modifications like spoiler top or radiator pan configuration to tweak the automobile for various tracks.
The Subsequent Gen automobile, with its modern, carbon fiber underbody, revitalized racing at mile-and-a-half tracks however struggles at smaller tracks. The brand new short-track bundle has made little distinction on the small ovals (Phoenix, Richmond and Martinsville) this yr.
As a result of followers usually cite lead modifications as a measure of a ‘good race’, I used NASCAR’s lead change stats. These numbers award credit score to at least one driver for main every lap firstly/end line. They don’t embrace passes throughout a lap, or passing in the remainder of the sphere.
I’ll summarize my conclusions after which take you thru the information.
- The standard of short-track racing varies extensively over completely different automobile generations and even inside a single technology. The issues didn’t all originate with the Subsequent Gen automobile.
- Passes for the lead haven’t modified considerably at Phoenix for the reason that Gen-4 automobile. The numbers of complete lead modifications are the identical, and the numbers of green-flag passes are fixed from the Gen-6 to the Subsequent Gen automobile.
- Whole lead modifications at Richmond are up with the Subsequent Gen automobile; nevertheless, the Subsequent Gen continues a development that began in 2020, with fewer cautions and extra lead modifications because of green-flag pit cycles. The typical variety of green-flag passes is down within the Subsequent Gen relative to Gen-6.
- Racing at Martinsville reached its peak when it comes to lead modifications with the Gen-5 automobile. The opposite technology automobiles have all produced races with few lead modifications. However solely for the reason that Subsequent Gen automobile have there been green-flag pit stops — and solely within the spring races. That implies the stage lengths are too quick in comparison with the tire sturdiness.
- The range of lengths, shapes and surfaces precludes a easy repair.
NASCAR has already said they’ve completed what they’ll with aero modifications. Attempting to engineer a tire that wears quicker is a horny choice that transfers the fee to Goodyear and the groups.
However faster-wearing tires will not be sufficient.
That leaves modifications that might essentially require bigger investments. It’s a sore matter in the mean time, as groups and NASCAR have but to achieve an settlement on methods to break up cash from the following media bundle.
However that’s what it might come right down to. The groups, the producers and NASCAR sitting down and determining how a lot cash house owners and NASCAR are prepared to spend to enhance the racing at these tracks.
Right here’s the information that led me to these conclusions.
Phoenix
The plot beneath exhibits lead modifications at Phoenix from 1991 to this yr’s race, with colours denoting automobile technology. I break up the Gen-5 automobile into 5a (the automobile with the unique wing) and 5b (the automobile with a spoiler.)
This plot exhibits that there aren’t any vital variations in lead modifications with completely different automobiles. The 4 races of the Gen-5b automobile had a mean of 19.5 lead modifications per race. Different automobile variations vary from a mean of 12 to 16 lead modifications per race.
The 12.6 common lead modifications per race within the Subsequent Gen automobile are on the low finish of that vary, however nonetheless inside it. The Subsequent Gen automobile hasn’t produced fewer than 10 lead modifications in a race, nor greater than 18.
As a result of it makes a distinction whether or not a lead change occurs on monitor or within the pits, I broke down the information by kind of lead change.
- GF is a green-flag move on monitor.
- GF-R is a move made on a restart or on the race begin.
- Lead modifications beginning with INH point out that the motive force inherited the lead because of one thing another person did, like pit or spin. I consider it as a passive lead change.
- ONPR signifies that the lead was taken by passing on pit street. Typically that’s because of whose pit field is previous begin/end and generally it’s a measure of who had the quicker pit cease.
- BTL means ‘beat to the road.’ Present guidelines enable the motive force on the entrance row who just isn’t the chief to beat the chief to the beginning/end line. When that occurs, they’re credited with main the final yellow-flag lap of the warning. In the event that they maintain on to the lead, I classify it as GF-R. If the lead was only for that one lap, it will get assigned BTL.
I solely have adequate information going again to 2017 for this evaluation, however even that restricted vary is helpful. The graph beneath exhibits the lead-change breakdown for Phoenix. Deal with the inexperienced, unhatched packing containers on the backside of every column that signify true green-flag passes for the lead.
In the event you didn’t know the place the automobile generations modified, you seemingly wouldn’t have the ability to inform from this graph. Within the stage racing period, Phoenix races have had between one and 7 green-flag passes. Final fall’s championship race had six green-flag passes, the second-highest variety of the races included. This yr’s race had 4 green-flag passes.
Racing at Phoenix is about the identical within the Subsequent Gen because it was within the Gen-6 automobile.
Richmond
The graphic beneath exhibits that the Subsequent Gen automobile supplied a big enhance in lead modifications at Richmond over the Gen-6. In reality, the Subsequent Gen automobile has the very best common variety of lead modifications per race.
Breaking down the sorts of lead modifications exhibits that the Subsequent Gen automobile has produced barely fewer green-flag passes on common than the Gen-6 automobile. Final spring’s race featured seven green-flag passes, the second-highest quantity in any stage-racing-era race at Richmond.
The rise in complete variety of lead modifications within the Subsequent Gen automobile is primarily because of will increase in green-flag pit stops. These, in flip, are because of fewer cautions. There have been solely two green-flag passes at this yr’s Richmond race and each got here whereas automobiles had been on moist climate tires.
The rise in inexperienced flag pitstop induced lead modifications (INH-GF) isn’t new with the Subsequent Gen automobile. It began round 2020.
Martinsville
Martinsville exhibits a distinct sample, even accounting for the truth that the final three spring races had been diminished from 500 laps to 400.
Final week’s Martinsville race featured 13 lead modifications in 415 laps, which corresponds to fifteen.7 lead modifications in 500 laps. That, in flip, is according to the imply variety of lead modifications in Gen-6 races.
Whereas the primary races with the Subsequent Gen automobile had minimal passing, this graph exhibits that the Gen 6, and even the Gen-4 automobile, have had races with fewer lead modifications.
In contrast to Richmond, the phenomenon of green-flag pit stops solely began at Martinsville with the introduction of the Subsequent Gen automobile -– and solely in spring races. The autumn 2023 race was the perfect for green-flag lead modifications with the Subsequent Gen automobile, with eight green-flag passes. That ties or beats all Gen-6 races besides one.
