On the morning of May 24, at Cao Thang Technical College, the annual Mini Car Racing model car competition entered the final round, marking the 10th year this technical playground has been held.

This year's competition attracted 350 students from 70 teams registered to compete, from 10 universities and colleges such as University of Technology (Ho Chi Minh City National University), Ho Chi Minh City University of Technical Education, Tra Vinh University, Van Lang University, Saigon Gia Dinh College...

After 2 rounds of technical testing and preliminary rounds, 27 excellent teams entered the final round.

Mr. Nguyen Ngoc Thanh - Head of the Department of Dynamic Mechanics at Cao Thang Technical College, head of the organizing committee - said that this is a technical competition for model cars designed and manufactured by students themselves, at least 50%, with dimensions not exceeding 80 x 50 x 50cm, using 2-stroke gasoline engines (22 - 33cm³).

The car is controlled remotely via phone via wifi connection, integrating both automatic control elements and modern connection technology.

Each race will consist of 3 cars from 3 teams. The car that completes 2 laps first will win. If all 3 cars fail to reach the finish line, the car with the longest distance traveled will win - Photo: TRONG NHAN

This year's theme "E-Power" encourages teams to integrate hybrid technology (a combination of gasoline and electric engines), aiming to save fuel and protect the environment.

The final round consisted of 13 knockout matches. Many teams went through tough challenges to complete the race, such as losing wifi connection, slipping chains, broken axles, and shutting down engines in the middle of corners or steep inclines.

Many teams had to urgently handle the situation in a short time to continue the race or accept stopping the game.

Nguyen Thai Thanh Long - a student majoring in automotive engineering at Cao Thang Technical College - shared that his team of 5 people had been preparing for 3 months.

"We focus on making the hardware really strong so that when a collision does not affect the electrical system. Many cars have damaged circuits when they collide, leading to loss of connection or requiring a long repair time," Long said.

Nguyen Trang Nguyen - a student at Binh Duong University - believes that the structural factor is the key.

"Some teams choose a lightweight structure to increase speed, while others prioritize a rigid frame to avoid damage. The engines of the teams are almost the same, so the difference lies in technical details, driving skills, and coordination in handling incidents between members," Nguyen analyzed.

In the end, the championship belonged to BIG HEAD team, Cao Thang Technical College.

Evaluating the competition, Mr. Tran Thanh Dat - General Secretary of the Ho Chi Minh City Automobile and Power Equipment Association - commented: "The competition helps students learn both professional and working skills. This is also an opportunity to discover and nurture technical talents for the automobile industry - an industry that is in great need of high-quality human resources, both skilled and innovative."
