Nascar Next Gen Car Specifications Revealed

Since NASCAR championship season has begun, Age Ty Gibbs might be the information that is currently being sought after. Ty Gibbs known to be the champion of the 2021 ARCA Menards Series champion and currently become the champion of NASCAR Xfinity Series.

Talking about NASCAR, the Next Gen, the seventh generation of the Cup Series racing vehicle, has been unveiled by NASCAR. The Next Gen modernizes the Cup vehicle, which has advanced slowly since the series’ founding in 1948, drawing inspiration from Australian Supercar and GT3 racing.

Even fuel injection wasn’t used until 2012 at the earliest (the Xfinity and Camping World Truck series still rely on carburetors). With the Next Gen, manufacturers can modify the race cars’ bodywork to more closely resemble the Chevrolet Camaro, Ford Mustang, and Toyota Camry with which they share a name. The new automobile has made enormous hardware advancements. Here is a closer look at the many modifications.

Body and Aerodynamics

The cosmetic changes to the Next Gen automobiles are the most noticeable. The teams are now able to more closely resemble the production vehicles after which they are named thanks to NASCAR. No stickers will be applied to the Toyota Camry to make it appear to have four doors, but the general profiles and noses will more closely resemble the street-legal versions of the Toyota, Chevrolet Camaro, and Ford Mustang.

Following the teams’ submission of their designs, NASCAR checks to see whether they adhere to their strict aerodynamic specifications. Furthermore, the bodies will be symmetrical. The passenger side used to stick out further than the driver’s in earlier models. The body is now able to generate additional side force as a result.

Body dimensions have decreased. Shortening the decklid has reduced the overall length by 6.0 inches, and the 50.4-inch roofline now sits around 1.5 inches lower than before. The wheelbase stays the same at 110.0 inches, while the body is 1.6 inches wider at 78.6 inches.

In order to restrict the amount of downforce a car can produce while also limiting speed, NASCAR will always specify the front splitter and rear wing. With the Next Gen automobile, two significant developments are taking place, though. Previously, teams would modify any exposed subsurface components to increase their aerodynamic efficiency or to add some downforce.


Previously, a race shop would have a raw steel tube entrance and a tube frame exit. That’s not the situation anymore. All of the frames, which now include a shared central cage with bolt-on front and rear substructures, will be supplied by Michigan-based Technique Inc. By replacing the bolt-on structures rather than dismantling or discarding the complete tube frame in the event of an unavoidable catastrophe, the objective is to save on operational expenses.

Currently, the vehicle depends on a single-adjustment damper to counteract high-speed irregularities on racetracks. Engineers may choose from a variety of dampers in the racing haulers, fine-tune them, and select the ideal spring rate. That won’t exist anymore. In order to provide a four-way adjustable damper at each corner, NASCAR has contracted with Ohlins. Teams will be able to fine-tune a single unit for numerous circuits thanks to the possibility of pit lane changes. The choice of springs will depend on the track, like previously.


Thankfully, NASCAR hasn’t altered the engine on these vehicles. Pushrod V-8 engines from Chevrolet, Ford, and Toyota will still have a 358 cubic inch displacement limit, with a 550 horsepower maximum for restrictor plate racing and a 670 horsepower limit for all other tracks.

The redesigned undertray necessitated a modification in how the exhaust is routed, unlike the present car, which has a crossover pipe that allows all eight cylinders to snarl their wonderful tone at the fans. Now that each bank of cylinders is exiting to the left or right of the car, the only engine you may hear from the stands is an inline-four. We’ll reserve judgment until we personally hear the automobile.

The four-speed gearbox is being replaced by a five-speed transaxle from X-Trac in the transmission announcement. The series’ increased gearing will allow for more gear changes when it visits road courses, according to the engineering departments, even if NASCAR’s final-drive options will prevent downshifting at high-speed ovals. The transaxle helps NASCAR’s goal of creating a platform that can be modified over time by, gasp, allowing for potential hybridization of the powerplant. It is unknown when that technology will be used in NASCAR.

Brakes, Tires, and Wheels

The spectacle that takes place in pit lane is a significant component of a NASCAR race. A race may be won or lost by the meticulously planned tire-changing procedure in which five lug nuts per wheel are blasted by high-rpm air guns. With the launch of the Next Gen, the outdated 15-inch wagon wheels will be retired and replaced by an 18-inch forged aluminum wheel provided by BBS.

The Bottom Line

Aside from the exciting information about Age Ty Gibbs, which is right now is at 20, we should appreciate for Nascar Next Gen Car Specifications which make Nascar championship even more exciting.

However, even though the car looks stunning both in print and in pictures, the all-new automobile has undergone significant alterations, but the key concern is how the vehicles will race. Until they make their debut in 2022 at Daytona International Speedway, we won’t know that. As NASCAR is a motorsport, not an entertainment series, we can only hope for some thrilling racing.
