You may be thinking of dragsters. NASCAR gets 5-7 mpg:

As you suggested, how many laps per gallon depends on
the track and the kind of racing involved (short
track, superspeedway [various lengths], plate, road).
Funny Car numbers:
- During idle, a Funny Car consumes a gallon of fuel every 15 seconds. Balance
of weight is such an issue that if the car idles too long, it will be too light
in the nose and will lift the front wheels during initial acceleration. For
anyone that watches drag racing, he or she knows that this might result in the
car steering directly into the wall.
- One 4.73 second quarter mile run consumes 15 gallons of fuel at about
$15/gallon (or more). That is a fuel efficiency of 0.016 miles per gallon. If
these were on the street, the EPA would be furious.

Top Fuel dragsters consume 64 gallons per minute at speed:

A top fuel dragster can consume 6 U.S. gallons (23 L) of nitromethane for a
quarter-mile (400 m) run in about 4.5 seconds, which comes out to 24 gallons per
mile (5600 L per 100 km).
