NASCAR has confirmed that Denny Hamlin's No. 11 Toyota will be among two cars set to be taken back to their R&D Center for a full teardown this week.

While post-race technical inspection at Chicagoland Speedway went down without any issues, making Chase Briscoe's eero 400 victory official, NASCAR is set to scrutinize some cars further.

Hamlin finished third on Sunday, extending his lead at the top of the Cup Series standings. However, his car will now be taken back to Concord, North Carolina and face further scrutiny.

That also goes for Alex Bowman's No. 48 Hendrick Motorsports Chevrolet. Bowman finished Sunday's race in fifth position - his third top-five finish of the season so far.

Why does NASCAR inspect cars further?

So, what does being taken for a teardown mean for those cars exactly? Well, cars are taken back to the R&D center from time to time, and often, it is just routine. However, if something illegal or that violated a rule were to be found during the added inspection, there would naturally be consequences.

This happened when Hendrick Motorsports' No. 17 Chevrolet, driven by Chase Elliott in the O'Reilly Auto Parts Series last season, was seized post-race at Pocono.

During inspection at their R&D Center, NASCAR found that the team's vehicle violated Section 14.3.3.2.1.1 K&L (Main Frame Rail Conical Receivers) of the NASCAR Rule Book.

As a result, hefty penalties followed. Crew chief Adam Wall was suspended for three races, the team was fined $40,000, and the team was docked 40 owner points and 10 playoff points.

However, for the most part, the further inspections are for educational purposes, as outlined on NASCAR's official website: "Sometimes, NASCAR will choose cars to take back to the R&D Center, but that’s more for engine education than anything else."

This happened after Las Vegas, with Christopher Bell's No. 20 and Erik Jones' No. 43 both inspected further at NASCAR's R&D Center with no resulting penalties.

That was also the case following Darlington, when Austin Cindric and Carson Hocevar's cars were the vehicles under scrutiny on that occasion, and no punishment was forthcoming.
