What makes a diesel car.

The diesel engine remains the rational choice for drivers who cover high annual mileages on motorways. Fuel consumption on the combined cycle is typically 15–25% lower than a comparable petrol engine, and the torque advantage at low revs makes overtaking effortless and towing capacity high. A full tank of diesel in a large saloon or estate can cover 900 km or more.

Modern diesel engines — equipped with AdBlue injection and advanced particulate filters — meet the latest emissions standards and run cleanly in urban environments. For company car drivers, fleet operators, and high-mileage private users, the economics still make a compelling case: the higher initial cost is offset by fuel savings within two to three years of typical use.
