The 2026 Mercedes-Benz S-Class is a petrol sedan with AWD and seating for 5. It belongs to the W223 generation. The S 580 4MATIC is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured S 580 4MATIC version develops 503 hp and 700 Nm (516 lb-ft) of torque. Its listed 0-100 km/h time is 4.4 seconds, which is seriously quick. Top speed is listed at 250 km/h (155 mph). Its power output is about 73% above the peer average. Its 0-100 km/h time is about 27% quicker than the peer average. The figures establish its straight-line performance on paper, but they do not substitute for measured braking, handling or ride-quality tests.
Fuel economy and range
The listed fuel consumption is 9.0 L/100km. Fuel-tank capacity is 76.0 litres (20.1 US gallons). Recorded CO2 emissions are 205 g/km. Consumption, emissions and range can be measured under different regional procedures, so like-for-like comparisons should use the same market and test cycle.
Dimensions and practicality
Its exterior dimensions are 5,289 mm (208.2 in) in length, 1,954 mm (76.9 in) in width, and 1,503 mm (59.2 in) in height, while the wheelbase measures 3,216 mm (126.6 in). Cargo capacity is listed at 550 litres (19.4 cu ft), expanding to 1,340 litres (47.3 cu ft) with the rear seats folded. The cabin is configured for 5 occupants. Listed curb weight is 2,145 kg (4,729 lb). That cargo volume is about 26% above the peer average. The measurements are useful for comparison, although seat comfort, access and the shape of the load area still need to be judged in person.
In perspective
Compared with nearby petrol sedan models from the same period, the 2026 Mercedes-Benz S-Class is strongest on power and acceleration, while price stands out as the principal numerical compromise. That conclusion is drawn from the recorded specifications rather than a road test. A final choice should also account for local pricing, equipment, comfort and a test drive.
