This is a highlight video of an extreme off-road monster car race where accidents are rife everywhere. There is a motorsport that challenges human limits by driving through off-road areas. Since it is impossible with a regular car, the body of the car must be modified to overcome the extreme conditions. Those who participate in these extreme motorsport competitions must use all their knowledge of cars to change the shock absorbers and suspensions to make them wider and larger, and change the wheels to use giant paddle tires or heavy-duty tires. These vehicles have a grotesque appearance with a large lower body and a small upper body, and they are called monsters because of the loud noise generated by the high output. They make the vehicles they have modified with great difficulty for the sole purpose of using them in a competition. When they encounter enormous obstacles and difficulties, the vehicles explode with high output and are destroyed, or the engine overheats and catches fire. You can feel the terrifying vibration and power of monster cars at the competition venue. The loud noise and the smell of exhaust fumes from burning engines are a bonus. However, the competition venue is always crowded with spectators. There is a risk of accidents such as stones and rocks flying out of the wheels and accidents that could slip and crash into the spectators at any moment, but people risk their lives to watch the competition in order to feel the charm of the monster. Nevertheless, special safety measures for spectators in these extreme motorsports competitions are lacking. As is the case with extreme sports competitions in the US and Europe, spectators who want to feel the excitement rather than safety should approach the stadium as much as possible and avoid the dangers themselves. Spectators who watch this competition praise the athletes who overcome obstacles that seem impossible. Extreme motorsports competitions are classified by the type of obstacle and each mission. In this video, we will introduce cliff climbing, lake crossing, and rock crossing. The vehicle that succeeded in crossing the water uses a 1,600 horsepower twin turbo engine and paddle tires to cross the water surface of about 400m without sinking. Considering that the Genesis G80 model has about 400 horsepower and the Ferrari SF90, the highest-performance supercar, has 980 horsepower, you can guess how powerful this vehicle has been customized. It seems impossible to climb a nearly vertical cliff with a car, right? Only a few cars succeed, and most cars break or flip over, but no one gets hurt thanks to the safety design of the car body. This place in Utah, USA, is surprisingly marked as a road on Google. While regular cars pass by bypassing it, many special vehicles are said to be challenging the victory. At a stadium in the US, tens of thousands of spectators gather every year to enjoy this monster competition. Large heavy equipment vehicles jump and do aerial spins as if they are doing gymnastics, and the spectators cheer louder when the monster vehicles fail rather than succeed. Although it may seem a bit extreme, the determination of the players participating in extreme motorsports competitions seems great. It is said that players who fail further study vehicle modifications for the next competition. The efforts of players who challenge the limits of nature in this way can become the foundation for the advancement of automobile technology.
