Toyota Gazoo Racing Malaysia is gearing up for the 2023 Sepang 1000 KM Endurance Race (S1K) with a focus on defending the overall title they secured the previous year. The team plans to enter a Toyota Vios in the MTC Class, with drivers Tengku Djan Ley Tengku Mahaleel and Naquib Azlan returning to the competition. Additionally, dealer team Wing Hin Motorsports will participate with two Toyota Yaris cars in the MTC Class, driven by Boy Wong and former Gazoo Racing Rookie Class driver Amer Harris.
The S1K event will also feature the third edition of the Gazoo Racing (GR) Vios Enduro Cup within the SP2 Class. This cup has gained popularity as a season finale for drivers already engaged in the GR Vios Challenge and GR Vios Sprint Cup. The GR Vios Enduro Cup attracts a diverse range of drivers, including teenagers, a father and son duo, a husband and wife team, and several female drivers.
