The number one fuel selection for the Mercedes S320 is diesel.
Fuel types for Mercedes S320:
We urge you to take your driving habits into account before settling on a specific fuel type. Do you find yourself driving more in urban settings or on open highways and expressways? How much distance do you travel in an average week?
If you drive mostly short distances, range is not crucial - so electric, plug-in or petrol are obvious choices. For daily long journeys, electric cars make the most sense if you can charge easily. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. Diesel cars can still make sense if you drive very far and don't have access to charging. Take into account that several countries restrict high-emission diesel engines from their city zones.
The Mercedes S320 only comes in the sedan body type in the UK. Usually fitted with four doors, the saloon or sedan body type has been popular with families for a long time. With its versatile design, the saloon caters to a range of needs, from daily commutes to longer journeys, and remains a symbol of elegance and practicality in the automotive world.
The Mercedes S320 is a mildly popular car within its segment but still it has some competitors.
