I've never attended a 'meet,' but after reading about what Dr.Andrew Franks was doing at U.C.Davis,California,the cars are approx.:
*3.5 sq-ft frontal area
*Driver is shoe-horned in to the 'car' and incapable of solo ingress/egress
*Cd 0.13
*200-psig bicycle tires
*a couple hundred pounds all-up weight
*Briggs & Stratton modified lawnmower engine
*Burn at WOT up to around 20-mph,cut power and coast down to 8-mph,then bump-start the engine and repeat for a few laps.
*The car is kept in laminar boundary layer running solo on a wind-protected closed-course
*No speed-bumps
*No turns
*No braking
*No electrical loads other than ignition
*Fuel is drawn from a burette and mpg is extrapolated on a mass basis
