Toyota and Mazda Test Decarbonization Tech in Thailand Race

Toyota and Mazda used a 24-hour endurance race in Thailand to test new decarbonization technologies for vehicles [1, 2].

This initiative marks a shift toward using competitive racing as a real-world laboratory. By testing these systems under extreme stress, the companies aim to find viable alternatives to battery electric vehicles for reducing carbon emissions [1, 2].

Toyota entered a hydrogen-engine car featuring superconducting technology [1, 3]. According to company data, this superconducting enhancement allows the vehicle to achieve 1.3 times the range of a comparable gasoline vehicle ^[3]. The technology is designed to minimize energy loss and maximize efficiency during the grueling race conditions.

Mazda focused on a different approach by deploying a system capable of capturing CO₂ directly from the vehicle's exhaust [1, 2]. While Toyota seeks to eliminate carbon at the source through hydrogen, Mazda is testing the ability to mitigate emissions from existing internal combustion frameworks.

Akio Toyoda, Chairman of Toyota Motor Corporation, highlighted the importance of maintaining a diverse range of powertrain options. He said that a car using an engine that emits only water is one option for achieving carbon neutrality.

Toyoda also noted the impact on the automotive supply chain. He said that many suppliers have built their businesses around engines, and asked what their future would be if battery electric vehicles were the only option. He said that hydrogen engines hold value in this context ^[1].

The endurance race began on May 17, 2024 [1, 2]. Both manufacturers utilized the 24-hour window to gather data on how these experimental systems perform over long durations, and under high thermal loads [1, 2].
