Hybrid retained the earlier EF-series engine. The Hybrid was discontinued in April 2010, as the hybrid drive system proved a bit too expensive for a microcar, while returning negligible fuel economy benefits for what is already a very efficient vehicle. In April 2015, the Cargo received a minor update, changing to a new four-speed automatic and an electronic throttle system (as recently introduced on the S500 Hijet Truck). In November 2017, the Hijet/Atrai received a thorough facelift, with a redesigned front treatment with a prominent trapezoidal grille. The tenth generation Van/Microbus as well as the ninth and tenth generation truck have also been marketed in Japan by Toyota since December 2011. They are called "Toyota Pixis" Van and Truck respectively. As for the Hijet, they have the new KF engine of 660 cc. Hijet Truck (S500, S510) In September 2014, the tenth generation Hijet cabover trucks was introduced, replacing the S200 line which had remained in production for a full fifteen years. The Truck is mid-engined as before, with either rear-wheel drive or optional four-wheel drive (S510). Unlike the ninth generation Hijet Truck, chassis codes end with a "P" for trucks as well as box van versions. As with the S201 predecessor, they have the new KF engine of 660 cc. In December 2021, the CVT option was introduced for the Hijet Truck. Hi-Max (S501) The tenth generation Hijet Truck was launched in Indonesia as the Daihatsu Hi-Max on 10 November 2016. Unlike the Japanese market Hijet in the restricted kei class, it used the 998 cc 1KR-DE engine, the same engine used in Ayla hatchback but producing less power figures, at 5,000 rpm and of torque at 4,000 rpm. The Hi-Max has the S501RP chassis number and was assembled at Astra Daihatsu Motor's Sunter plant. It stopped production in November 2019 and was removed from Daihatsu's Indonesian website in April 2020 due to low sales caused by buyers' preference for larger models such as the Gran Max or the Indonesian-built Suzuki Carry. In 2019, only 95 units of Hi-Max were sent to dealerships, compared to nearly 36,000 units of the Gran Max. A total of 1,731 units were sold. Eleventh generation (S700, S710) Hijet Cargo/Atrai (S700, S710) The eleventh-generation Hijet Cargo/sixth-generation Atrai was introduced on 20 December 2021. It is based on the Daihatsu New Global Architecture. Variants and derivatives There were some versions of the Hijet sold outside
