Mercedes C-Class All-Terrain

Which C-Class All-Terrain version to buy

Both engines sit Front, longitudinal. Both have 4 valves per cylinder. C200 2.0 AT lists Direct injection (direct); fuel-system type on C220d 2.0 AT is not measured.

C200 2.0 AT is the quicker, lighter petrol car: 204 hp, 7.5 s to 100 km/h, 1710 kg kerb. C220d 2.0 AT is the torque and economy car: 440 Nm, 5.6 L/100 km mixed, 126 g/km CO2. Top speed is the same: 231 km/h. City and highway consumption are not measured on both.

Specs: C220d 2.0 AT vs C200 2.0 AT

Both engines sit Front, longitudinal. Both have 4 valves per cylinder. C200 2.0 AT lists Direct injection (direct); fuel-system type on C220d 2.0 AT is not measured.

Engine: what the extra displacement buys

C220d 2.0 AT displaces 1993 cc; C200 2.0 AT displaces 1496 cc. The diesel is 497 cc larger (33% more swept volume). Peak power is almost a wash: 204 hp versus 200 hp — the petrol is 4 hp stronger (2%).

Specific output is not. C200 2.0 AT makes 204 hp from 1.496 L → 136.4 hp per litre. C220d 2.0 AT makes 200 hp from 1.993 L → 100.4 hp per litre. The petrol is 36 hp/L denser.

Torque is the opposite. C220d 2.0 AT has 440 Nm at 1800-2800 rpm. C200 2.0 AT has 300 Nm at 1800-4000 rpm. The diesel has 140 Nm more (47%). Diesel torque is fully in by 2800 rpm; petrol torque stretches to 4000 rpm but never reaches 440 Nm.

Power peaks: C220d 2.0 AT at 4200 rpm (147 kW); C200 2.0 AT at 5800-6100 rpm (150 kW). Compression: diesel 15.5, petrol 10.5. Bore × stroke: C220d 2.0 AT 82 × 92.3; C200 2.0 AT 80.4 × 73.7. Fuel: diesel Diesel; petrol 98.

If the job is mid-range pull with a loaded Estate 5-door, C220d 2.0 AT is the arithmetic winner. If the job is peak power per litre and a higher-rev peak, C200 2.0 AT is.

Performance: 0-100, top speed, kg per hp

C200 2.0 AT: 7.5 s to 100 km/h. C220d 2.0 AT: 7.8 s. Petrol is 0.3 s quicker. Top speed is 231 km/h on both — extra 4 hp and 80 kg less mass do not raise the catalogue maximum.

Weight-to-power: C200 2.0 AT 1710 / 204 = 8.38 kg/hp. C220d 2.0 AT 1790 / 200 = 8.95 kg/hp. Petrol carries 0.57 kg less per horsepower. That matches the 0.3 s gap; it does not match the 140 Nm gap. Acceleration to 100 km/h in this pair follows mass and peak hp more than peak torque.

mpg / fuel use, tank, CO2, range from mixed figures

Mixed consumption: C220d 2.0 AT 5.6 L/100 km; C200 2.0 AT 7.6 L/100 km. Petrol uses 2.0 L/100 km more (36%). City and highway figures are not measured for both — do not treat mixed as a city or highway number.

Tank is 40 L on both. On mixed figures only: diesel 40 / 5.6 × 100 ≈ 714 km; petrol 40 / 7.6 × 100 ≈ 526 km. Difference ≈ 188 km per tank. CO2: C220d 2.0 AT 126 g/km; C200 2.0 AT 153 g/km — petrol is 27 g/km higher (21%). Both Euro 6.

Same tank, same drive, same 9-speed Automatic: the extra money for diesel, if any, is not in the data. What the numbers buy is 2.0 L/100 km less mixed fuel, 27 g/km less CO2, and ~188 km more mixed range.

Dimensions and weight

Ground clearance is 170 mm on both. Wheel sizes are not measured on both. Suspension is Independent, spring front and rear on both. Front brakes Ventilated disc; rear Disc.

Kerb: C220d 2.0 AT 1790 kg; C200 2.0 AT 1710 kg — diesel is 80 kg heavier. Gross: 2400 kg versus 2325 kg — diesel is 75 kg higher. Payload from those two figures: diesel 2400 − 1790 = 610 kg; petrol 2325 − 1710 = 615 kg. The petrol is 5 kg more payload despite a lower gross, because kerb falls more than gross (80 kg vs 75 kg).

Generations: what changed

There is 1 generation (5 generation, from 2021-08-01, `stop` not measured), Estate 5-door, 2 versions. No second generation to compare. Within this generation both versions share start date 2021-08-01, AWD, Automatic 9, 170 mm, 40 L, Euro 6, 231 km/h. The generation did not split body types; it split fuel.

Which version to choose

Choose C220d 2.0 AT if mixed use and torque matter: 440 Nm, 5.6 L/100 km, 126 g/km, ~714 km mixed from 40 L, 1993 cc diesel Turbo Inline 4. Cost versus petrol: 80 kg extra kerb, 0.3 s slower to 100, 4 hp less, 8.95 kg/hp instead of 8.38.

Choose C200 2.0 AT if kerb and sprint matter: 1710 kg, 7.5 s, 204 hp, 136.4 hp/L, 615 kg payload from catalogue masses. Cost versus diesel: 2.0 L/100 km more mixed, 153 g/km CO2, 300 Nm, 98 fuel, ~526 km mixed from the same 40 L.

Do not choose on top speed, clearance, gears, drive, tank, eco class, or wheels: 231 km/h, 170 mm, 9, AWD, 40 L, Euro 6 are identical; wheels not measured. Do not choose on city or highway mpg: both not measured. Do not choose on generation: there is only 5 generation.
