Major Association of Southeast Asian Nation (ASEAN) countries rely on internal combustion engine (ICE) passenger vehicles. National incomes and infrastructure development also drive motorcycles’ popularity. Hybrid and electric vehicle penetration only accounted for 0.3%, 1.3%, and 9%, respectively, in the total new passenger vehicle sales in Indonesia, Malaysia, and Thailand. As the automotive market matures, hybrid and electric vehicle and charging infrastructure development will bring new excitement to the market. Indonesia, Malaysia, and Thailand together sold 38,119 units of hybrid and electric vehicles in 2020. Indonesia recorded the fastest growth, with a 47.5% year-on-year increase, rising from 720 units in 2019 to 1,062 units in 2020. The governments of these three countries encourage the sales and production of energy-efficient and electric vehicles. In the long term, the adoption and application of electric powertrain and energy-efficient technology will continue to grow in the automotive market. Japanese OEMs have the largest market share in the ASEAN automotive market. They will continue to offer hybrid powertrain through alternative powertrain selections, such as gasoline and hybrid, provided by the same passenger vehicle model in the ASEAN market. Meanwhile, premium OEMs will continue focusing on plug-in hybrid electric vehicles (PHEVs). The study covers the hybrid and electric passenger vehicles market in ASEAN countries, emphasizing Indonesia, Malaysia, and Thailand. With a market overview based in 2020, the historical period of the study covers 2018–2020, while the forecast period is from 2021 to 2025.
