The 2021 Mercedes-Benz C-Class is a petrol sedan with AWD and seating for 5. It belongs to the W205 LCI generation. The C 300 4MATIC is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured C 300 4MATIC version develops 258 hp and 370 Nm (273 lb-ft) of torque. Its listed 0-100 km/h time is 5.7 seconds, which is decisively quick for everyday road use. Top speed is listed at 250 km/h (155 mph). Its power output is about 25% above the peer average. Its 0-100 km/h time is about 23% 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 7.8 L/100km. Fuel-tank capacity is 66.0 litres (17.4 US gallons). Recorded CO2 emissions are 178 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 4,686 mm (184.5 in) in length, 1,810 mm (71.3 in) in width, and 1,442 mm (56.8 in) in height, while the wheelbase measures 2,840 mm (111.8 in). Cargo capacity is listed at 460 litres (16.2 cu ft), expanding to 1,370 litres (48.4 cu ft) with the rear seats folded. The cabin is configured for 5 occupants. Listed curb weight is 1,600 kg (3,527 lb). That cargo volume is close to 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 2021 Mercedes-Benz C-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.
