The Lexus GS 450h, the world’s first rear-wheel drive hybrid power sports saloon, made its motor racing debut in Japan’s only 24-hour race last month.

The high-performance hybrid shone at the Tokachi International Speedway in Hokkaido (in northern Japan) finishing fourth in its production car class and 17th overall in a field of 33.

The gruelling, twice around the clock event allowed Lexus engineers to collect data on the potential of hybrid systems in motor sports, especially relevant as such systems are being discussed for imminent introduction to Formula 1.

The racing GS 450h added to hybrid motor sport history, joining the Toyota Prius which was the first, and remains the only hybrid car to start and finish an FIA sanctioned event, the 5,000mile Midnight Sun to Red Sea Rally in 2002.
