Found this and thought it may be of interest.
I know this is held each year by Russia and other countries are invited to partake, I believe the US was invited one year but turned it down.
This video shows Mongolia, Vietnam, Syria and Venezuela competing.
I believe these are T-72B3 but if others know different please let me know.
Should be an Olympic sport in my opinion!
Two hundred mile race. Oval track. Stock tanks. Done like NASCAR. Tanks can shoot at fixed targets while racing with hits earning time off the clock. To make things more interesting, anti tank gun teams from the same countries also get to compete, firing paint rounds at the tanks. A hit on any tank accept your own takes time off the clock. Land mine paint bombs are lobbed onto the track at random. Hitting one adds time to the clock. Losing your barrel adds a big block of time to the clock. Maybe have close support aircraft bomb the tanks with paint bombs.
Edit: Make the targets vehicles spaced around the track–armored personnel carriers, infantry fighting vehicles, tanks, technicals, whatever. Machine guns with paint rounds are now in on the action. Main gun hits takes out anything. Machine gun hits only take out and score points when used on thin skins.
Those T-72s would make some very interesting models with those camo colors.
Instead of NASCAR’s Car of Tomorrow (CoT) it could have T-72B3’s the tank of yesterday! (ToY)
T-80U would be a fun choice.
@SableLiger Reynier, thanks I may have to get one of those now just so I can do a ‘racing’ tank. Quiet like the blue Syrian or red Vietnamize schemes from the video.
@Armor_Buff Wade, we need a NATO and Western/other countries version of this, various versions of Leopards and Abrams plus Challenger 2 or 3, Ariete, Leclerc etc all in bright colours racing round a track and target shooting all against the clock.
Mmmm… 
I can see a 1/72 project forming in my head!
Nothing says race tank like a big spoiler on the rear for “down force” and a pair of canards on the nose for racing down the long straights of a super speedway!
Throw in a pitstop where the tank crew (no pit crew like in other car racing) have to change a wheel, or is that going a step to far?
In a 24 hour Lemans style absolutely in shorter races, maybe check wheel bearing grease, tracks & oil?
Or change a track link on each side and zero (Bore sight?) or what ever the proper name for it is the main gun.
The US participated in 2015; there is a video on the net showing them powering through a water hazard and stalling out their tank (restarting on the other side of the hazard), followed by another competitor who enters the turn approaching the water hazard a bit too fast and, where earlier competitors pulled a drift in the turn, they pulled a much harder drift ending in a 270° roll, leaving the tank on its right side.
Or for Soviet type tanks, A turret altitude launch for tie breaker, if there is a tie…
If they’re still holding this event, it’s probably a BYO
Mal
There is a NATO tank event minus the colors.
I think this makes for a very sporty contender…
It’s a hybrid, with rear weight bias for better cornering and it’s a Porsche as the next generation of RainBow 
warrior…in this scheme…

That said you should build a nascar inspired VK.45.
