NASCAR does have specific requirements for the cars that enter the races.
Part of the requirements are stock parts, for example, the hood and trunk are stock.
Although, there can be modifications done to other parts of the vehicles, they had to say within guidelines set by NASCAR.
For the most part, the only thing that is left as stock on the cars is the hood and the trunk.
In the recent past it was common to notice similarities among the cars in a race.
Typically the majority of the cars weigh around 3,300 pounds and the wheelbase is around 110 inches.
The shape of the cars needs to meet specific criteria.
This is to ensure equality among the driver's.
One would have to win because of their skill, not because they had different aerodynamics.
Also, this would minimize some of the tactics used by the drivers to get ahead.
Safety is very important when it comes to the design of the cars and the interior of them as well.
Some of the features for safety that can be found inside a NASCAR are a reinforced gas tank, HANS (head and neck support system), roll cage and a windshield made of Lexan.

The gear ratio is 1:1 and the rest of the ratios are set at 1.
28:1.
Technically, these cars could run in the Formula One races.
In 2006, NASCAR announced the new template for the cars.
The CAR of Tomorrow, seems to still have many of the drivers and teams concerned.
