A criticism that is leveled at major racing series today, from NASCAR to IndyCar, is that the cars are "spec" cars – all the same except for paint.

The yellow #26 is a Crosley-powered "upright," a car with the driveline centered in the chassis.
The red #16 is a Triumph-powered rear-engined machine.
The blue #1-X is a Rotax-powered offset roadster.
Each of three of these cars was built to a common set of specifications, but clearly those specifications left plenty of room for innovation!
