How NASCAR’s Next-Gen Car Will Be Judged

There are three qualifications that will ultimately determine the success of the revolutionary new NASCAR Cup Series car that will debut next season during Daytona Speedweeks.

Those pillars are closer competition, cost containment and manufacturer relevance.

Of the three, that last qualification is arguably the most important. Simply stated, history will remember how many additional OEMs the Next-Generation platform was or wasn’t responsible for delivering during its life cycle.

This is a matter of not just the chassis and body but also the hybrid engine that is set to follow it over the next several seasons.

It would not an overstatement to suggest that this is a pivotal crossroads in the history of NASCAR and the sanctioning body has responded aggressively.

Make no mistake, the Next-Gen is a spec car in every sense of the word, no matter how much the industry may not like using it. They prefer to call it a standardized parts platform. Regardless, for the first time in Cup Series history, single source manufacturers will be responsible for building the chassis, providing parts and supplying a carbon composite body.

What is different is the stylings of each body with Chevrolet, Ford and Toyota having distinctively different shells that more closely resemble the showroom counterpart Camaro, Mustang and Camry. The platform will continue to use the current generation internal combustion, pushrod V8 produced by each manufacturer as well.

At some point over the next decade, that engine will be phased out with a hybrid, and that is when NASCAR must deliver additional OEMs.

“In my opinion, the importance of this car can’t be overstated,” said NASCAR president Steve Phelps in February. “There are many things that Next Gen will do for us as a sport when it rolls out in 2022. The styling is going to be amazing. I think the racing is going to be better based on the aerodynamics of the vehicle.

“The costs associated with the vehicle will be lower in terms of its absolute cost as well as the number of cars that will be necessary to run and run up front. Those are all wins for us.

“I believe new OEMs and the relevance of this sport, where this sport now ranks within the sports entertainment landscape, is different than it was a year ago, two years ago, three years ago. With that, as well as the Next Gen car coming out next year, I think there’s going to be some renewed interest from an OEM perspective.”

And again, that renewed interest has to begin with a new engine.

“I know for a fact we will not have a new OEM unless we change our engine,” Phelps said. “I would be surprised if a new OEM came in without some type of electrification. I’m not talking about all-electric, I’m talking about a hybrid system.”

The only manufacturer that could theoretically come in before a hybrid is introduced would be Dodge, which still has a current-generation Cup Series engine platform used until the current generation car was introduced in 2013, but the cost to develop a hybrid in addition to modernizing the 2012 engine would be astronomical.

NASCAR had considered implementing a carbonfiber chassis but opted to retain its traditional steel tubular frame equivalent for now. The chassis will be supplied by Technique Inc., owned by former Indy car racer Ronnie Johncox, with the company having opened a facility in North Carolina.

In the name of safety, the driver will be moved 1.6” further towards the center of the car and door bars have been moved further outwards.

The Next-Gen features a split exhaust system, which now means exits on both sides, which has generated a radically different sound during tests over the past year. That’s also crated a driver concerns over cooling and driver comfort.

Instead of a four-speed manual gearbox, the Next-Gen features an Xtrac produced five-speed sequential shift (plus reverse) transmission, that will use a ‘gear stick’ rather than a paddle-shifter. It was important to NASCAR that drivers would have to take a hand off the steering wheel to shift on restarts and on road courses.

The car feature independent rear suspension — a departure from the classic solid axle rear suspension. Regulations will keep drivers in fifth gear for most tracks, with Martinsville Speedway in Virginia being an obvious exception.

If that sounds like a Australian Supercar, that’s because there are countless borrowed elements from that discipline, a byproduct of NASCAR executives spending a considerable amount of time Down Under to learn about the platform.

There’s also a lot of GT3 built into the Next-Gen, the total package reflecting NASCAR’s increased road and street racing future.

“There is so much different about it with the independent rear suspension and the way the rear differential is, the suspension, the shocks, the springs, you name it,” 2017 Cup Series champion Martin Truex Jr. said. “It’s a whole different ballgame.”

Even pit stops will look drastically different next season with the center-lock single lug nut aluminum wheel replacing the traditional five lug steel platform. The so-called ‘gas man’ could become the most important crew member next season with a simplified wheel changing process.

The car could also make use of sports car style clamp-on refueling hose at some point.


Not even a spec car will be enough to prevent the Cup Series from being dominated by Hendrick Motorsports, Joe Gibbs Racing, Team Penske and Stewart-Haas Racing.

After all, look at IndyCar, which remains the personal playground of Team Penske and Chip Ganassi Racing more often than not.

However, also like IndyCar which creates opportunities for its other teams to nail the set-up and win races, NASCAR hopes to bridge the gap to teams like Richard Childress, JTG Daugherty Racing and Front Row Motorsports with greater regularity.

With so many spec components, the cars brought to the track by the elite and the mid-tier teams will be more similar in 2022 than ever before.

NASCAR is still fully committed to a low horsepower (550) and high downforce rules package to keep cars closer together on intermediate tracks. The addition of aero ducts, the rear diffuser and changes to the underbody and all designed to off-set the challenge the current generation car has in traffic.

The short track and road course package will feature even less horsepower (670) than the current 750 package.

“Overall picture in my eyes: We need something that you can get up behind a guy and at a mile-and-a-half track get near his bumper in the corners,” Truex said. “That’s something that needs to happen, and we haven’t been able to do that really in the past few seasons. Hopefully, we can get back to that somehow.”
