What does d4st mean on the back of a Toyota?
2 Answers
Toyota's d4st indicates that the model is equipped with an enhanced version of the 4-stroke dual-injection turbocharged system engine. Here, 'd' stands for dual injection system, '4' represents 4-stroke, 's' signifies the enhanced version, and 't' denotes turbocharging. Taking the 2021 Toyota Corolla as an example, it belongs to the compact car category with body dimensions of 4635mm in length, 1780mm in width, and 1455mm in height, featuring a wheelbase of 2700mm and a fuel tank capacity of 50 liters. The 2021 Toyota Corolla is powered by a 1.2t turbocharged engine, delivering a maximum horsepower of 116ps, a peak power output of 85kw, and a maximum torque of 185nm, paired with a 10-speed continuously variable transmission.
I was also curious about the D4ST badge on the rear of my car when I first started driving. Later, I found out it's Toyota's engine technology code, standing for Direct Injection 4-Stroke with Turbo. Simply put, it's a turbocharged direct-injection four-stroke engine. This technology is used in models like the Camry or Highlander, enhancing power while saving fuel—urban driving consumes about one liter less per 100 kilometers compared to regular engines. My personal experience with such a car is quick acceleration from a standstill, especially making highway overtaking effortless, with the turbo engagement smoothly tuned to avoid abruptness. Toyota introduced this technology to meet environmental regulations and boost competitiveness, integrating direct injection to reduce emissions and a high compression ratio design to minimize carbon buildup. As an owner, I recommend regular air filter changes and using the right engine oil to prevent turbocharger issues and extend its lifespan. In short, though this small badge might seem insignificant, it carries substantial meaning and can serve as a reference point when buying a car.
