Before NASCAR mandated the restrictor plate on superspeedways, the fastest lap ever was clocked at 220 mph. The highest speed ever attained in a straight line, back stretch run was 238 mph. With today's restrictor plate carbuerators, cars rarely exceed 190 mph.

Bill Elliot, in 1987, set the all time speed record in qualifying at Daytona: 210.364 mph. He later set the all time speed record at Talladega that same year: 212.809 mph. "Awesome Bill from Dawsonville" set these speed records in a Ford Thunderbird.

Around 1994, there was a top speed contest that included many different types of race cars. A Nascar race car won the competition, hitting 248 mph. Of course, this was with grille tape, good preparation, and a long straight-line run. It won the compeition. It may be assumed that with today's more aerodynamic body and more powerful engines, a modern day Nascar car will shatter the 248 mph mark on a long straight.

Now they can get up to 300mph or more.
