The then Nationwide Series unveiled its "Car of Tomorrow" (CoT) at the July 2010 race at [[Daytona International Speedway]]. Before being fully integrated in the 2011 season, it was also used in 2010 races at [[Michigan International Speedway]], [[Richmond International Raceway]] and [[Charlotte Motor Speedway]].<ref>{{cite web|url=https://ca.sports.yahoo.com/nascar/news?slug=ap-nascar-nationwide-newcar&prov=ap&type=lgns |title=Yahoo!

The body and aerodynamic package differs from the NASCAR Cup Series cars, marketing American [[pony car]]s from the 1960s such as the [[Ford Mustang]], [[Dodge Challenger]], and [[Chevrolet Camaro]]. The change to share the same CoT chassis as the Cup series resulted in the wheelbase being lengthened from 105 to 110 inches<ref>{{cite web|author=Mark Aumann |url=http://www.nascar.com/2007/news/headlines/bg/10/28/nationwide.cot.2009/index.html |title=COT planned for 2009 Nationwide Series debut&nbsp;– Oct 28, 2007 |publisher=Nascar.Com |date=October 28, 2007 |access-date=July 13, 2010}}</ref><ref>{{Cite web|url=http://www.nascar.com/2007/news/headlines/bg/10/28/nationwide.cot.2009/index.html|title=NASCAR.COM - COT planned for 2009 Nationwide Series debut - Oct 28, 2007|date=February 18, 2010|access-date=May 26, 2022|archive-date=February 18, 2010|archive-url=https://web.archive.org/web/20100218001749/http://www.nascar.com/2007/news/headlines/bg/10/28/nationwide.cot.2009/index.html|url-status=bot: unknown}}</ref><ref>{{cite web | url=https://bleacherreport.com/articles/413381-nationwides-car-of-tomorrow-debuts-at-daytona | title=NASCAR: Daytona Debuts Nationwide's Car of Tomorrow | website=[[Bleacher Report]] }}</ref>

Each manufacturer uses a distinct body design (similar to 1960s muscle cars), built within strict aerodynamic guidelines provided by NASCAR. The [[Chevrolet]] car body currently resembles the [[Chevrolet Camaro (sixth generation)|SS]], after initially running the [[Chevrolet Impala#Ninth generation (2006–2016)|Impala]] and then the [[Chevrolet Camaro (fifth generation)|Zeta-based Camaro]] (which coincided with GM's Cup car being its four-door Zeta counterpart, the [[Holden Commodore (VF)|Holden VF Commodore based Chevrolet SS]], being used in Cup at the time). [[Ford Motor Company|Ford]] uses the [[Ford Mustang (seventh generation)|Mustang Dark Horse]]. [[Toyota]] runs the [[Toyota Camry (XV70)|Camry]], reconfigured in 2015 to resemble the current production model. Toyota announced they would be running the [[Toyota Supra#A90|GR Supra]] starting in 2019, replacing the Camry, which had been run in the series since Toyota joined the Xfinity Series in 2007.<ref>{{Cite web|url=https://www.toyota.com/concept-vehicles/supra/xfinity-series/|title=2019 Toyota Supra Xfinity Series Race Car {{!}} Toyota Nascar|website=www.toyota.com|language=en-US|access-date=September 21, 2018}}</ref> [[Dodge]] teams used the [[Dodge Challenger (2008)|Challenger R/T]] model, despite the manufacturer pulling all factory support after 2012 (though it continued in Canada as FCA Canada still supports the Pinty's Series). Following Dodge's exit, smaller underfunded teams continued to run second-hand Challenger chassis without factory support (thus earning the nickname "Zombie Dodges").<ref>{{cite magazine |url=https://www.roadandtrack.com/motorsports/news/a7155/nascar-dodges-without-factory-support/ |title=Zombie Dodges race in NASCAR after factory pulled plug |first=Jeffrey N. |last=Ross |magazine=[[Road & Track]] |date=February 25, 2014 |access-date=November 24, 2018}}</ref><ref>{{cite web|url=https://ca.sports.yahoo.com/nascar/news?slug=nascar_com-retro.racing.nationwide.new.car-20091031&prov=nascar_com&type=lgns |title=Yahoo!

Since FCA had pulled factory support years earlier, no new body was submitted for competition, ending the possibility of running a Challenger chassis in the series.<ref>{{cite web |last1=Nguyen |first1=Justin |title=NASCAR Bids Farewell to Dodge after 2018|url=https://www.thecheckeredflag.co.uk/2018/11/nascar-bids-farewell-to-dodge-after-2018/ |website=www.thecheckeredflag.co.uk |date=November 16, 2018 |access-date=November 20, 2018}}</ref>
