What is the equivalent displacement of a 1.5T engine compared to a naturally aspirated engine?
2 Answers
Equivalent to a 1.8L to 2.0L naturally aspirated engine. However, in terms of fuel consumption, the 1.5L turbocharged engine has lower fuel consumption while delivering stronger power. The 1.5L turbocharged engine is currently the mainstream engine displacement. Below is an introduction to the 1.5T engine: 1. Introduction: A turbocharger is a technology that uses exhaust gases from an internal combustion engine to drive an air compressor, providing additional power to the engine. The turbocharger can effectively increase the engine's air intake, enhancing its power and torque. For engines of the same displacement, the power output can increase by approximately 40% when equipped with a turbocharger. 2. Usage: When the vehicle is first started, it needs to warm up for 1-2 minutes before driving. Especially in winter, after the vehicle has been running at high speeds, it should idle for about a minute before shutting off to allow the turbocharger to cool down. Turbocharged models should not be operated continuously for extended periods.
I've been driving a 1.5T car for three years, and it feels much more powerful than the old 2.0L naturally aspirated engine, especially when overtaking on highways. However, during cold starts before the turbo kicks in, the power delivery isn't as smooth as the 2.0L. After researching, I found most mainstream 1.5T engines' performance parameters are close to 2.3L naturally aspirated levels - like Honda's 1.5T that squeezes out 193 horsepower, outperforming many 2.4L engines. But the fuel consumption is much better, my daily commute shows only 7.6L/100km. When choosing a car, don't just look at displacement numbers; test drive to feel the turbo engagement timing, as tuning varies significantly between models.
