Toyota does apply turbocharging technology in some of its models. For example, the Harrier is equipped with a 2.0L twin-scroll turbocharged engine (8AR-FTS), which delivers 231 horsepower and 350 Nm of torque, paired with a 6-speed automatic transmission. Such powertrain combinations are quite popular in the local market. However, not all Toyota models utilize turbo technology. For instance, the 2025 Corolla still primarily features naturally aspirated engines (1.8L/2.0L) in the local market, while the performance-oriented GR86 employs a 2.4L naturally aspirated horizontally opposed engine. Toyota's turbocharging technology harnesses exhaust gases to drive the turbine, enhancing intake efficiency while balancing power and fuel economy. Its reliability has been proven through years of market validation. For example, the twin-scroll design reduces turbo lag and optimizes combustion efficiency. Turbocharged engines require higher-octane fuel and regular maintenance, whereas naturally aspirated engines remain favored for their lower maintenance costs.
