Toyota Motor Corp. and GrabTaxi Holdings Pte. Ltd. on Dec. 18 revealed their "Total-care Service" designed to enhance and expand ride-hailing platforms.

The service, which aims to improve cost and operational efficiency, will be introduced in Singapore and will offer fleet management, auto insurance and vehicle maintenance packages.

About 1,500 Toyota cars owned by Grab will test the service, run by the Japanese carmaker's marketing arm, Toyota Motor Asia Pacific Pte Ltd., or TMAP. Following the initial introduction, TMAP and Grab will offer Total-care Service across Southeast Asia.

The carmaker aims to increase the number of its vehicles in Grab's fleet by 25% by 2020 in Southeast Asia. Toyota also expects to implement its Toyota Production System to streamline the ride-hailing business' operations.

Toyota's Philippine arm offered car replacement and ownership packages to Grab drivers in October.

The move is part of Toyota's increased focus on mobility services business and the Japanese carmaker is set to launch a mobility service joint venture in Japan with SoftBank Group Corp. in 2019.
