Diesel (Mercedes E 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 (Mercedes C class) 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."
Mercedes E class is more dynamic to drive. Mercedes E class engine produces 42 HP more power than Mercedes C class, whereas torque is 380 NM more than Mercedes C class. Thanks to more power Mercedes E class reaches 100 km/h speed 0.3 seconds faster.
