Diesel (Mercedes C class) engines typically outperform gasoline engines in terms of fuel efficiency and low-end torque. This makes them more economical and better suited for towing or long-distance travel. However, gasoline (Volvo V70) engines mostly are lighter, quieter, and offer better acceleration and responsiveness, especially in smaller vehicles. For more information, see the article "Diesel or Petrol: Fuel Economy and Key Differences."
