Which model is the Corolla d4t?
2 Answers
Corolla d4t refers to the 2021 Corolla 1.2T model. Meaning of D4T: D-4T indicates that this Corolla is equipped with a 1.2T four-cylinder direct injection turbocharged engine. D4 refers to the inline 4-cylinder engine, and T stands for turbocharging. Turbocharged engine: A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of the exhaust gas from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller pressurizes the air delivered from the air filter pipeline, forcing it into the cylinders. As the engine speed increases, the exhaust gas discharge speed and turbine speed also increase simultaneously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel.
I believe the Corolla D4T refers to the Toyota Corolla model equipped with a 1.2-liter direct-injection turbocharged engine, with the engine code D-4T, emphasizing direct fuel injection technology to enhance fuel efficiency and power response. It was first introduced in the eleventh-generation Corolla, approximately between 2014 and 2018, and later continued into the twelfth-generation 2019 model and subsequent versions. This engine delivers around 116 horsepower, with peak torque achieved as early as 1500 rpm, providing smooth acceleration, especially excelling in urban driving conditions. The combined fuel consumption remains at about 5.8L/100km. I often mention in car enthusiast groups that this engine is quite common in the European and Chinese markets, known for its high reliability and low maintenance costs. Minor issues like spark plug wear suggest checking every 30,000 km. For tech enthusiasts, the Turbo system paired with a CVT transmission ensures smooth gear shifts, making it an economical choice worth considering for both new and experienced drivers.
