What does e/t mean?

E: It means the engine uses an electronically controlled fuel injection system. T: Stands for Turbo, which means turbocharging. The principle and function of turbocharging are introduced as follows: The principle of turbocharging: A turbocharged engine is an engine that relies on a turbocharger to increase the intake air volume of the engine. A turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gas from the engine as power to drive the turbine in the turbine chamber (located in the exhaust passage), which in turn drives the coaxial impeller (located in the intake passage). The impeller compresses the fresh air delivered through the air filter pipe and then sends it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase synchronously, thereby increasing the degree of air compression. As a result, the engine's intake air volume increases accordingly, allowing for an increase in the engine's output power. The function of turbocharging: The main function of turbocharging is to increase the engine's intake air volume, thereby enhancing the engine's power and torque, making the car more powerful.
When it comes to e/t, this term is quite common on the racetrack, especially for someone like me who’s into drag racing. e/t stands for "elapsed time," which refers to the seconds a vehicle takes from the starting line to the finish line. For example, if a car completes a 1/4-mile run in 10.5 seconds, its e/t is reported as 10.5. This directly reflects how fierce the acceleration performance is and serves as a key indicator of a car’s speed. Beginners sometimes confuse it with "trap speed." e/t emphasizes the time itself, while trap speed is the instantaneous speed at the finish line. Car enthusiasts use it to compare the effects of modifications—if you upgrade to a stronger engine or optimize the tires, the e/t might drop by 0.5 seconds, a gap that can be the difference between winning and losing on the track. Remember, don’t try this recklessly in daily driving—safety first. But once you understand e/t, watching racing events becomes more exciting, as you can instantly spot the hidden pros.
