What is the equivalent displacement of 2.7T?
2 Answers
2.7T is equivalent to a 3.0 displacement, and if it's a 2.7T twin-turbocharged engine, it's equivalent to a 4.0 displacement. A turbocharged engine refers to an engine equipped with a turbocharger. A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. Below is an introduction to turbocharged engines: Principle: A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It uses 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 compresses the air delivered from the air filter pipe, pressurizing it into the cylinders. Power: When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable more fuel to be burned, and by correspondingly increasing the fuel amount and adjusting the engine speed, the engine's output power can be increased.
I've driven quite a few turbocharged (T) cars. The 'T' in 2.7T stands for turbocharging, not displacement. Converted to a naturally aspirated engine, the power is roughly equivalent to a 4.0L to 4.3L NA engine. For example, my V6 turbocharged car with a 2.7T engine delivers stronger acceleration than my neighbor's 4.0L off-road vehicle. However, turbocharged and naturally aspirated cars feel completely different to drive—when the turbo kicks in, it's like someone gives you a kick from behind, whereas NA power comes on linearly. Nowadays, many performance cars use small-displacement turbocharged engines for their low energy consumption and strong power.
