Most MMA fights usually take place in a cage, but what about inside a car?

Yes, it's a thing, and it's actually getting quite a lot of interest.

Welcome to 'Car Jitsu', the brainchild of lifelong mixed martial artist Vik Mikheev, who came up with this rather strange concept in 2020.

He has posted dozens of videos of these so-called matches on YouTube with over three million views.

The Russian started his channel when he was looking for something to keep himself occupied during the coronavirus pandemic.

Per Mikheev's YouTube page, he is apparently a black belt in BJJ and Judo. He also claims to have a PHD in Mathematics.

“In 2020, I came up with the idea of doing competitive grappling in vehicles,” he told Bloody Elbow. 

“Since October of 2020, I and my friends run small tournaments of Car Jitsu to study the aspects of jiu-jitsu application in such a confined space.“

MMA News - Punch Club reveal their version of Car Jitsu

Russian MMA promotion Punch Club has brought out its own version of Car Jitsu

But now Russian MMA promotion Punch Club appear to have taken things a step further by coming up with their very own version with a unique twist of course.

That's right, the team that brought you phone booth fighting have come up with another crazy idea.

This time, both contestants sit in the front seat of the vehicle with a seatbelt strapped tightly across their chest before a horn sounds to mark the start of the fight.

Whatever will they think of next?

It remains unclear whether Mikheev has anything to do with it or not but one thing's for sure fans seem to be enjoying it.

What are the rules of Car Jitsu?

The original rules are as follows:

"All submissions are legal. 3 min (or till submission) on driver’s seat and front passenger’s seat, then switch and 3 min more (or till submission).

"If the score by submission is equal, competitors move to the back seats for 4 min round. If no submissions happen on the back, the competitor with more pts wins.

"Points are counted for guard pass (3 pts), mount (4 pts), back mount (4 pts), and knee on belly (2 pts) positions. And yes, competitors can use seat belts."
