The Kia Sportage has long been one of Ireland's favourite family SUVs, offering a great combination of practicality, reliability, comfort, and value. One of the biggest decisions buyers face is choosing between a diesel or petrol engine.
The right choice depends largely on how you use your vehicle. High-mileage motorway drivers often benefit from diesel, while city drivers and lower-mileage users may be better suited to petrol.
