Although hybrid vehicles have the advantages of fuel efficiency and environmental friendliness, they also have some obvious drawbacks. First, the higher purchase cost: due to the complex powertrain and battery pack, the price of hybrid models is usually 20% to 30% higher than that of fuel-powered vehicles of the same class. For example, the Toyota Vios hybrid version is priced at about 160,000 ringgit in Thailand, which is significantly higher than the fuel-powered version. The complex powertrain increases repair difficulty, while the battery lifespan typically ranges from 8 to 10 years. Replacing the battery may cost tens of thousands of ringgit, substantially increasing long-term ownership expenses. Additionally, hybrid models exhibit limitations in power performance. Battery degradation issues result in poorer acceptance in the used car market, with residual values potentially depreciating sharply after five years. Therefore, consumers must carefully balance the fuel-saving benefits against the higher overall costs when making purchasing decisions. While hybrids are particularly suitable for urban commuting, they may not be ideal for long-distance travel or high-performance requirements.
