One of the key priorities for those looking to buy a car is finding low-consumption models, especially due to fuel costs. In diesel vehicles, fuel efficiency is directly related not only to engine displacement but also to transmission structure and driving conditions.

Fuel economy continues to be one of the deciding factors in car preferences.

Consumption values announced in factory tests can drop to lower levels, especially in manual transmission options. However, heavy city traffic, driving habits, load status, and road conditions can cause real-world consumption to differ from catalog data.

Differences can occur between catalog consumption values and real road conditions.
Transmission structure and torque delivery affect driving economy in diesel vehicles.
