Diesel Engines: These engines provide less speed torque, so they have more overtaking power and also enables with towing. Being noisier such engines irritate more but this sounding problem is getting a significant improvement in recent models.
Petrol Engines: The driving experience with the petrol engines is more refined and is less noisy. These engines easily pick-up maximum speed but have less power than diesel engines.
Diesel Engines: These engines have high compression ratio than petrol engines and do not use a spark plug to ignite the fuel. Collectively they are more efficient than petrol engines.
Petrol engines: The petrol engines use a spark plug to burn the fuel and they have less fuel compression ratio than diesel engines.
