How fast are the NASCAR cars? The average top speed of a NASCAR car is just over 321km/h, or 200mph. Compared to a Formula 1 car, this is quite a bit slower, as they hit speeds of 360km/h (223mph). Indycar – another major American racing series – is faster still, reaching speeds of 380km/h (236mph).Jun 11, 2021
358 cubic inchesThe engine is large -- 358 cubic inches (5.87 L). Not many street-cars have engines this big, and the ones that do usually generate well over 300 hp.

212.809 miles per hourThe fastest speed ever reached in NASCAR's history was recorded at 212.809 miles per hour at the Talladega Superspeedway in Talladega, Alabama. The record was set in 1987 by Bill Elliot, making him NASCAR's fastest driver! His lap is the fastest official qualifying mark in NASCAR's history and still stands today.
There is an established pit road speed limit for each race. Since NASCAR cars do not have speedometers, the first pace lap of each race is run at pit road speed so drivers can get a tachometer reading for pit speed. There are a variety of other safety rules (see penalties above) that must be followed.
