NASCAR's streamlined inspection process explained

NASCAR will streamline its at-track inspection process next season, with a rollout of the new system coming this weekend at Chicagoland Speedway.
Playoffs teams – and most likely their teammates – will not be run through the new system. NASCAR officials are not looking to disturb the Playoffs. However, officials want those not competing for the championship to begin acclimating to the new system by testing it a few times during the postseason.
Shown to reporters last week at the NASCAR R&D Center, the sanctioning body is aiming to be more efficient with its system.


Here's a breakdown of how it will work:
Beginning in 2018, the at-track inspection process will consist of three stations, which is down from the five currently used. Those three stations will be Engines, Chassis and Templates / LIS. The Templates / LIS system is what will be handled in a new way. This station is an enclosed structure that will house no fewer than 17 high-definition black and white cameras and eight projectors. Inspected here will be the conformity of the vehicle's body – currently completed as part of the template grid and template module stations – weights and the skew of the car, which is currently inspected at the Laser Inspection Station.


The cycle time through this station is expected to be less than 90 seconds compared to the minimum three minutes it currently takes for these stations. And the overall inspection time for all three stations will be four minutes. Currently, all five stations take around 12 minutes.


The cars will be rolled up onto a platform so they can be put under the scrutiny of the cameras and projectors. The cameras will take pictures eight times a second as a full-body scan of the car is done. The report from that scan is expected to go to both NASCAR and the teams.
In simple terms, when looking at the body scan, green means good. Anything in red will be an indication further inspection might be needed.


What's important to note is this system will not cause NASCAR to add any rules to the rule book. Everything being inspected is staying the same, but this system inspects differently, can be more precise and goes a lot further than the current process.
Also, while NASCAR will use this for just the Monster Energy NASCAR Cup Series next year, doing so in the Xfinity Series is not being ruled out. It's likely that series will go to this system at some point in the future.

 

Taking 12 minutes for a 5 stage inspection seems really quick to me considering

that the templates must avoid bending even the slightest amount and the

clearance tolerance is down to thousandths of an inch.
