Car Number 1: The Boulder Mobile, driven by The Slag Brothers (Rock Slag and Gravel Slag) - cavemen (covered with hair like Cousin Itt from The Addams Family; their design was recycled for "Captain Caveman", a later Hanna-Barbera series) driving a wheeled boulder. The Slag Brothers sometimes reconstructed their car from scratch using their clubs.

Number 2: The Creepy Coupe, driven by The Gruesome Twosome (Big Gruesome and Little Gruesome) - monsters (Big spoke like Boris Karloff and Little like Peter Lorre), driving a car with a belfry; the belfry housed a dragon and various ghosts and ghouls. The Creepy Coupe was able to fly short distances through use of the dragon's wings.

Number 3: The Convert-a-Car, driven by Professor Pat Pending - a mad scientist in a car that could change into just about anything that moves.

Number 4: The Crimson Haybailer, driven by Red Max - an air ace (loosely based on WWI German aviator, Max Immelmann) in a car/plane hybrid that was capable of limited flight, usually just enough to leapfrog over racers and/or obstacles in its path. The Crimson Haybailer also had a machine gun mounted, which was sporadically used.

Number 5: The Compact Pussycat, driven by Penelope Pitstop - a woman racer driving a pink feminine car with personal grooming facilities. Said facilities would sometimes backfire on the other racers - shampoo foam hitting them in their faces, for instance. Penelope went on to star in her own spin-off series, "The Perils of Penelope Pitstop".

Number 6: The Army Surplus Special, driven by Sergeant Blast and Private Meekly - two soldiers racing an army jeep/tank hybrid. The Army Surplus Special made use of its tank facilities while racing, including its cannon.

Number 7: The Bullet-Proof Bomb (a.k.a. The Roaring Plenty), driven by The Ant Hill Mob (led by Clyde, with Danny, Kurby, Mac, Ring-A-Ding, Rug Bug Benny and Willy) - gangsters in a 1920's saloon car. They all appeared in the later spin-off series "The Perils of Penelope Pitstop", but with name changes (still led by Clyde, the others then being Dum Dum, Pockets, Snoozy, Softy, Yak Yak and Zippy) and a new sentient car, Chugga-Boom.

Number 8: The Arkansas Chuggabug, driven by Luke and Blubber Bear - hillbillies in a wooden buggy driven by a coal-fired range.

Number 9: The Turbo Terrific, driven by Peter Perfect - an All-American Jock (he had a crush on Penelope, so often stopped to help) driving a drag racer that regularly fell to bits.

Number 10: The Buzz Wagon, driven by Rufus Ruffcut and Sawtooth - a lumberjack and a beaver in a wagon with buzzsaws for wheels, which gave it the ability to cut through almost anything, damaging or destroying the object in the process.

Number 00: The Mean Machine, driven by Dick Dastardly and Muttley - the villains of the series, in a rocket-powered car with lots of concealed weapons. Their sole aim was to win every race by hook or by crook. Drat and Double Drat! They went on to star in their own spin-off series, "Dastardly & Muttley in their Flying Machines".

(My thanks to Glenn Leider for his help with the above results table - we both independently viewed all 34 races on DVD and we are in complete agreement that the information in the table is correct.)
