The 2021 Toyota Harrier offers two powertrain options in the Malaysian market: a 2.0-liter naturally aspirated four-cylinder petrol engine (codenamed 3ZR-FAE) and a 2.5-liter hybrid system (codenamed A25A-FXS). The former delivers a maximum output of 171 horsepower and a peak torque of 207 Nm, paired with a CVT transmission. The latter boasts a combined power of 218 horsepower and features an Electronically Controlled Continuously Variable Transmission (E-CVT). Both configurations cater to Malaysian consumers' dual demands for fuel efficiency and performance, with the hybrid version standing out particularly in fuel economy—perfect for the frequent stop-start nature of local road conditions. It's worth noting that Harrier's Dynamic Force engine series incorporates advanced technologies like high-speed combustion and a variable cooling system, which effectively boost thermal efficiency. The hybrid variant further comes with Toyota's proven THS II system, optimizing energy distribution via the PCU (Power Control Unit). For Malaysian users, the choice should factor in daily driving distance. If city commuting is the main use, the hybrid version significantly cuts fuel consumption, while those who often drive long distances might prefer the linear power delivery of the 2.0-liter petrol model. Additionally, Toyota's well-established local after-sales network ensures convenient maintenance for both engines, with adequate support for regular servicing and parts supply.

The 2023 Toyota Harrier available in the Malaysian market has a gasoline version equipped with a 2.0-liter four-cylinder naturally aspirated engine (model 3ZR-FAE), while the hybrid version features a combination of a 2.5-liter four-cylinder Atkinson cycle engine and an electric motor. Therefore, both the gasoline and hybrid versions come with a four-cylinder configuration, not a three-cylinder design. For Malaysian consumers, four-cylinder engines usually have an edge over three-cylinder ones in terms of smoothness and noise control. Meanwhile, Toyota's Dynamic Force series engines are well - known for their high thermal efficiency, which can balance power and fuel economy. It's worth noting that although there is a global trend in the automotive industry to reduce engine displacement and the number of cylinders, Toyota still adheres to the four - cylinder foundation in its mainstream SUV models to ensure driving quality and reliability. Three - cylinder engines are more commonly found in small cars or entry - level models. It is recommended that you take a test drive at an authorized dealer before buying a car to experience the performance differences of different powertrains in person.

In the Malaysian market in 2023, the Toyota Harrier offers two powertrain options, both of which adopt Toyota's well - established hybrid technology. Among them, the 2.5 - liter inline - four Dynamic Force engine paired with the THS II hybrid system is the main configuration. The combined output of this system can reach 222 horsepower. Coupled with the E - CVT transmission, it provides a smooth driving experience. At the same time, it has excellent fuel consumption performance. The official data shows that it can reach about 5.3L/100km, which is especially suitable for the congested urban traffic conditions in Malaysia. It's worth mentioning that the Harrier's hybrid system uses a nickel - metal hydride battery pack. Compared with lithium batteries, it is more adaptable to the tropical climate and shows good durability. For consumers who pursue power, a 2.0 - liter turbocharged version is also available in some markets, but currently, the hybrid version is the main offering in Malaysia. This engine uses the D - 4ST dual - injection technology, which balances power and fuel economy. Its technical principle is similar to that of the Lexus NX series, reflecting Toyota's modular development strategy. In terms of maintenance, Toyota has established a well - developed service system for its hybrid system in Malaysia. The battery pack usually comes with an 8 - year/100,000 - kilometer warranty, giving car owners more peace of mind.
