What is the difference between diesel and petrol engines in a Vauxhall Insignia?

I am thinking of purchasing a Vauxhall Insignia, but I am not sure which engine type to go for. Can you explain the differences between diesel and petrol engines in this car?

Diesel engines are typically more fuel efficient than petrol engines, making them a better choice for longer drives. However, petrol engines may have better acceleration and performance, so it ultimately depends on your driving habits and needs.

In terms of maintenance, diesel engines tend to have lower maintenance costs. However, petrol engines may have a longer lifespan. It's important to regularly service your car regardless of the engine type.

If you're concerned about emissions and the environment, diesel engines generally produce lower CO2 emissions. However, they may also emit more harmful pollutants such as particulate matter. Consider your priorities when making your decision.
