With those mighty engines, NASCAR vehicles are certainly not the lightest in motorsport. Moreover, their weight is regulated. What is the average weight of a NASCAR car?
Answer 3,200 lbs
The NASCAR rules say the car's weight should be under 3,400 lbs for it to be eligible to compete. However, manufactures do their best to achieve at least some degree of weight reduction. As a result, most NASCAR racers weigh in at around 3,200 pounds.
