The Mercedes-Benz S-Class stands out with heated front seats, ventilated seats and Burmester audio that you will not find on the Mercedes-Benz C-Class. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The Mercedes-Benz S-Class uses a Petrol producing 320kW and 520Nm of torque, sent through a automatic to a AWD layout. It covers the 0-100km/h sprint in 4.9 seconds.
The Mercedes-Benz C-Class responds with a Petrol making 150kW and 300Nm, paired to a automatic driving the rear wheels. It gets to 100km/h in 7.8 seconds.
The Mercedes-Benz S-Class has the clear power advantage at 320kW vs 150kW. In the real-world sprint, the Mercedes-Benz S-Class is 2.9s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The Mercedes-Benz S-Class measures 5,179mm long on a 3,106mm wheelbase, 428mm longer than the Mercedes-Benz C-Class at 4,751mm (2,865mm wheelbase). The longer wheelbase on the Mercedes-Benz S-Class generally means more rear legroom.
