Mercedes C-Class AMG: Which Version to Buy and Why
The Mercedes C-Class AMG catalogue spans nine listed generation entries, which consolidate into five generations produced from 1994 onward. The choice is unusually broad: Sedan, Coupe, Cabrio and Estate 5-door bodies; Gasoline, Diesel and Plug-in powertrains; outputs from 231 hp to 680 hp; and RWD or AWD.
The Mercedes C-Class AMG catalogue spans nine listed generation entries, which consolidate into five generations produced from 1994 onward. The choice is unusually broad: Sedan, Coupe, Cabrio and Estate 5-door bodies; Gasoline, Diesel and Plug-in powertrains; outputs from 231 hp to 680 hp; and RWD or AWD. The clearest dividing line is between the large-displacement, naturally aspirated earlier cars and the smaller boosted later models. The fifth-generation C63 AT and C63SE 2.0 AT lead the data at 680 hp and 1,020 Nm, while the fourth-generation C63S 4.0 AT offers up to 510 hp and 700 Nm with a lower listed kerb weight. Buyers prioritising traction can choose the fourth-generation C43 3.0 AT or fifth-generation C43 2.0 AT with AWD; buyers seeking the lightest listed car will find it in the first-generation 3.6 AT at 1,460 kg.
Mercedes C-Class AMG generations compared
The first generation covers 1994–1997 as a Sedan with one listed version, followed by a 1997–2000 restyling with three entries. The original 3.6 AT produces 280 hp and 385 Nm. Restyled choices include C43 4.3 AT with 306 hp and 410 Nm and C55 5.5 AT with 347 hp and 510 Nm. All use RWD and Automatic transmissions, but the first-generation 3.6 AT has 4 gears while the restyled cars have 5.
The second generation covers 2001–2005 as a Sedan with six entries, with a 2004–2007 restyling adding four entries. It introduced two very different routes: C32 3.2 AT is a Compressor Gasoline V-shaped 6-cylinder car with 354 hp, while C30 3.0 AT is a Turbo Diesel Inline 5-cylinder car with 231 hp and 540 Nm. The restyling retained C30 3.0 AT and added C55 5.4 AT, a naturally aspirated Gasoline V-shaped 8-cylinder version producing 367 hp and 510 Nm. Every listed second-generation version is RWD with a 5-speed Automatic.
The third generation is represented by a 2007–2011 Sedan with four entries and a 2011–2015 restyled Coupe with nine entries. Every version is named C63 6.2 AT and uses a naturally aspirated 6,208 cc Gasoline V-shaped 8-cylinder engine, RWD and a 7-speed Automatic. Output varies by entry: 457 hp, 487 hp or 507 hp, with torque at 600 Nm or 610 Nm. This generation is therefore primarily a choice among body, output, weight and performance figures rather than fundamentally different powertrain layouts.
The fourth generation covers a 2015–2018 Cabrio with twelve entries and a 2018–2023 restyled Coupe with twelve entries. C43 3.0 AT combines a 2,996 cc Turbo Gasoline V-shaped 6-cylinder engine with AWD and a 9-speed Automatic, producing 367 hp before restyling and 390 hp after it. C63 4.0 AT and C63S 4.0 AT use a 3,982 cc Turbo Gasoline V-shaped 8-cylinder engine and RWD. Depending on the entry, the C63 produces 476 hp and 650 Nm, while the C63S produces 510 hp and 700 Nm. Pre-restyling C63 and C63S entries use a 7-speed Automatic; restyled entries use a 9-speed Automatic.
The fifth generation begins in 2022 as an Estate 5-door with four entries. All listed versions use a 1,991 cc Inline 4-cylinder engine, AWD and a 9-speed Automatic. C43 2.0 AT is Gasoline and produces 408 hp with either 500 Nm or 509 Nm. C63 AT and C63SE 2.0 AT are Plug-in versions rated at 680 hp and 1,020 Nm. These figures give the fifth generation the highest power and torque in the catalogue, but its C63 entries are also the heaviest listed at 2,145 kg and 2,165 kg.

Power per litre highlights how the range changed. The first-generation 3.6 AT develops about 77.6 hp per litre, and the 457 hp third-generation C63 6.2 AT develops about 73.6 hp per litre. The fourth-generation 510 hp C63S 4.0 AT reaches about 128.1 hp per litre. The fifth-generation C43 2.0 AT reaches about 204.9 hp per litre, while C63 AT and C63SE 2.0 AT each reach about 341.5 hp per litre.
Performance, fuel economy and mpg figures
The first-generation 3.6 AT reaches 100 km/h in 6.7 seconds and 250 km/h, with listed consumption of 17.6 L/100 km urban, 11.4 highway and 14.2 combined. The restyled C43 4.3 AT cuts the acceleration time to 6.5 seconds, while C55 5.5 AT records 5.5 seconds; both reach 250 km/h and list 11.7 L/100 km combined.
For the second generation, C30 3.0 AT records 6.8–7.0 seconds to 100 km/h, 245–250 km/h and 7.6–7.8 L/100 km combined. C32 3.2 AT records 5.2–5.4 seconds, 250 km/h and 11.5 L/100 km combined. Restyled C55 5.4 AT records 5.2–5.4 seconds, 250 km/h and 11.9–12.0 L/100 km combined. The C30 therefore uses 4.1–4.4 L/100 km less on the combined cycle than C55 5.4 AT, depending on the paired entries.
Third-generation C63 6.2 AT figures range from 4.2 to 4.6 seconds and from 250 to 280 km/h. Where fuel consumption is supplied, combined figures range from 12.0 to 13.7 L/100 km; for entries without consumption data, urban, highway and combined figures are not measured. The 507 hp version is listed at 4.2–4.3 seconds and 280 km/h.
Fourth-generation C43 3.0 AT figures range from 4.7 to 4.8 seconds and reach 250 km/h. Combined consumption ranges from 8.0 to 8.4 L/100 km before restyling and from 9.3 to 9.8 afterward. C63 4.0 AT ranges from 4.0 to 4.2 seconds, while C63S 4.0 AT ranges from 3.9 to 4.1 seconds. Top speed is 250 km/h for the listed C63 entries and 250–290 km/h for C63S entries. Listed combined consumption ranges from 8.4 to 10.4 L/100 km for C63 and from 8.6 to 10.4 L/100 km for C63S.
The fifth-generation C43 2.0 AT records 4.3 or 4.7 seconds, 250 km/h and 9.1 or 9.2 L/100 km combined. Urban and highway consumption are not measured. C63 AT and C63SE 2.0 AT both record 3.4 seconds, 250 km/h and 6.9 L/100 km combined; urban and highway consumption are not measured. They are 0.5 seconds quicker to 100 km/h than the quickest listed fourth-generation C63S 4.0 AT.
Dimensions, weight and wheels
The first-generation 3.6 AT weighs 1,460 kg kerb and 1,970 kg gross, with 150 mm clearance, a 62 L tank and 225/45 R17 front and 245/40 R17 rear wheels. Restyled first-generation entries weigh 1,470–1,570 kg kerb and retain the 150 mm clearance, 62 L tank and the same listed wheel sizes.
Second-generation entries weigh 1,480–1,635 kg kerb and 2,080–2,205 kg gross, with 120 mm clearance and a 62 L tank. C30 3.0 AT and C32 3.2 AT use 225/45 R17 and 245/40 R17 wheels. Restyled C55 5.4 AT uses 225/40 R18 and 245/35 R18 wheels; its kerb weight is 1,565 or 1,625 kg. Gross weight for individual second-generation entries is listed in the table data; where a measurement is absent elsewhere, it is not measured.
Third-generation C63 6.2 AT kerb weights range from 1,655 to 1,795 kg, while gross weights range from 2,160 to 2,275 kg. Clearance is 120 or 140 mm, the tank holds 66 L, and listed wheels are 235/40 R18 front and 255/35 R18 rear. For entries without wheel data, wheel sizes are not measured.
Fourth-generation Cabrio entries range from 1,690 to 1,925 kg kerb, with gross weights from 2,155 to 2,320 kg and clearance of 89 or 91 mm. The 2016 C63S 4.0 AT is listed at either 1,800 or 1,925 kg kerb depending on the database entry. Its wheels are listed as 245/35 R19 and 265/35 R19, or 255/35 R19 and 285/30 R19. The restyled fourth-generation Coupe entries range from 1,630 to 1,865 kg kerb and 2,155 to 2,320 kg gross. Clearance is 130 mm where supplied and not measured on the other entries.

C63SE 2.0 AT weighs 2,165 kg kerb and 2,650 kg gross. All have a 50 L tank; ground clearance and wheel sizes are not measured.
Weight per horsepower sharpens the comparison. The 1,460 kg 3.6 AT carries about 5.21 kg per hp. A 1,655 kg, 487 hp third-generation C63 6.2 AT carries about 3.40 kg per hp. A 1,680 kg fourth-generation C63S 4.0 AT carries about 3.29 kg per hp. The 2,145 kg C63 AT reaches about 3.15 kg per hp, despite weighing 465 kg more than that 1,680 kg C63S 4.0 AT.
Which Mercedes C-Class AMG version should you buy?
Choose C30 3.0 AT if listed combined consumption is the priority. Its best figure is 7.6 L/100 km, the lowest in the catalogue, and its 540 Nm exceeds the C32 3.2 AT by 90 Nm despite a 123 hp power deficit. The trade-off is acceleration: 6.8–7.0 seconds rather than 5.2–5.4 seconds.
Choose C43 3.0 AT if AWD and lower weight matter more than maximum output. The 390 hp restyled versions weigh as little as 1,630 kg and reach 100 km/h in 4.7–4.8 seconds. Against the 510 hp fourth-generation C63S 4.0 AT, C43 gives away 120 hp and 180 Nm but adds AWD and can use as little as 9.3 L/100 km combined.
Choose C63 6.2 AT for the naturally aspirated V-shaped 8-cylinder configuration and the largest displacement in the catalogue. The 507 hp version adds 50 hp and 10 Nm over the 457 hp version, reducing the best listed acceleration time from 4.4 to 4.2 seconds and raising top speed from 250 to 280 km/h.
Choose C63S 4.0 AT for the strongest fourth-generation power-to-weight proposition. Compared with C63 4.0 AT, it adds 34 hp and 50 Nm. In the quickest comparable entries, acceleration improves from 4.0 to 3.9 seconds and top speed rises from 250 to 290 km/h, while combined consumption remains 10.1 L/100 km.
Choose C43 2.0 AT if you want the fifth-generation Estate 5-door body without the weight of the Plug-in C63. At 1,735–1,810 kg, it is 335–430 kg lighter than the fifth-generation C63 entries. It gives up 272 hp and 511–520 Nm but still reaches 100 km/h in 4.3–4.7 seconds.
Choose C63 AT or C63SE 2.0 AT for the maximum catalogue figures: 680 hp, 1,020 Nm and 3.4 seconds to 100 km/h. C63 AT is 20 kg lighter than C63SE 2.0 AT, while both share the same listed power, torque, acceleration, top speed and combined consumption. No price or on-road-price comparison can be made because price data is not measured.
