2 Answers
Differences between the high and low power versions of Volkswagen's 1.4T engine: 1. Different power outputs: The high-power version has a maximum power of 110KW, maximum horsepower of 150PS, and maximum torque of 250NM; the low-power version has a maximum power of 96KW, maximum horsepower of 131PS, and maximum torque of 225NM. 2. Different engine models: The low-power model is CSTA; the high-power model is CSSA. Volkswagen is an automobile manufacturer headquartered in Wolfsburg, Germany, with models such as the Sagitar, Magotan, and Lavida. Taking the Lavida as an example, this car is produced by Shanghai Volkswagen, with body dimensions of 4605mm in length, 1765mm in width, and 1460mm in height.
The difference between Volkswagen's 1.4T high and low power engines mainly lies in software tuning. The high-power version optimizes turbo boost pressure and ignition timing through ECU, delivering higher horsepower, such as around 150 hp in the Golf GTI, with more aggressive acceleration and a strong sense of push-back. The low-power version is capped at around 130 hp, focusing more on smoothness and fuel efficiency, making it easier to drive in congested urban areas. The hardware foundation is almost identical, with no changes to components like the cylinder block or turbo. In terms of fuel consumption, the high-power version consumes slightly more, but the difference is minimal, less than 1 liter per 100 kilometers. For modifications, the low-power version can be upgraded to high-power levels with a simple software flash, making it a cost-effective option. Long-term maintenance costs are similar, so you can use either version with confidence.
