Removing performance cars, in terms of power, torque and power driving feel like is the case, a better injection, the conversion factor and the dual injection naturally aspirated gasoline engine is about 1.55 to 1.8:
1.0T equivalent to about 1.6 - 1.8L naturally aspirated
1.2T equivalent to about 1.8 - 2.0L
1.4T is equivalent to about 2.0 - 2.2L
1.5T equivalent to about 2.2 - 2.5L
1.6T is equivalent to approximately 2.3 - 2.7L
1.8T is equivalent to approximately 2.4 - 2.8L
2.0T equivalent to about 3.0 - 3.5L
2.3/2.5T is equivalent to about 3.5 - 4.0L
Look various tuning and technology base level.
More general direct injection engine (or a low-power version), most of the EFI engine, a conversion factor of approximately 1.3 to 1.5:
(See above focus on these attributive, in fact, a lot of people in contact with power T are in this category, you do not look good data above those of the engine)
1.0T equivalent to about 1.4 - 1.5L naturally aspirated
1.3T equivalent to about 1.6 - 1.8L
1.4T equivalent to about 1.8 - 2.0L
1.5T is equivalent to about 2.0 - 2.3L
1.6T equivalent to about 2.2 - 2.4L
1.8T is equivalent to approximately 2.3 - 2.5L
2.0T is equivalent to approximately 2.4 - 3.0L
