What is the equivalent displacement of a 1.2T engine?

[McAllison]

There is no specific conversion formula, but it can be estimated based on parameters. A 1.2T engine is typically tuned to produce between 100-130 horsepower, which roughly corresponds to a naturally aspirated engine in the range of 1.6-1.8 liters. Here are more details: 1. A 1.2T engine cannot be simply equated to a 1.6L or 1.8L naturally aspirated engine; it depends on the specific RPM conditions. 2. At initial acceleration, the 1.2T performs similarly to a 1.6L engine. However, once the turbo kicks in above 1000 RPM, the 1.2T engine delivers power equivalent to a 1.8L or 2.0L naturally aspirated engine. But at speeds exceeding 100 km/h, the 1.2T only matches the performance of a 1.6L engine.
