Mercedes A-Class AMG: Which Version Should You Buy?
The Mercedes A-Class AMG choice comes down to two priorities: the A 35/A35 versions offer the lower fuel-consumption figures, while the A 45/A45 versions deliver the strongest acceleration and highest power outputs. Every listed car uses a 1,991 cc turbocharged Gasoline inline-4 engine, a Robotic gearbox and AWD.
The Mercedes A-Class AMG choice comes down to two priorities: the A 35/A35 versions offer the lower fuel-consumption figures, while the A 45/A45 versions deliver the strongest acceleration and highest power outputs. Every listed car uses a 1,991 cc turbocharged Gasoline inline-4 engine, a Robotic gearbox and AWD. The catalogue covers the first-generation Hatchback 5-door from 2013 to 2016, its 2015–2018 restyling, the second-generation Sedan from 2019 to 2023, and the second-generation restyling produced from October 2022 onward. There are four generation entries in the source data, but they represent two numbered generations, each with a restyled phase.
Mercedes A-Class AMG generations: what changed?
The first-generation Mercedes A-Class AMG was a Hatchback 5-door produced from 2013 to 2016 with one version, named exactly 2.0 DCT. Its 1,991 cc engine produced 360 hp and 450 Nm, while the 7-speed Robotic gearbox sent power through AWD. Acceleration from zero to 100 km/h took 4.6 seconds, and top speed was 250 km/h.
The first-generation restyling ran from 2015 to 2018 and remained a Hatchback 5-door with one version, A45 2.0 DCT. Compared with the earlier 2.0 DCT, output rose by 21 hp and 25 Nm to 381 hp and 475 Nm. The zero-to-100 km/h time fell by 0.4 seconds to 4.2 seconds, while top speed stayed at 250 km/h. Both phases used a 7-speed Robotic gearbox and AWD.
The second-generation Mercedes A-Class AMG was listed as a Sedan from 2019 to 2023 with four catalogue records: two A 35 2.0 DCT specifications and two A 45 2.0 DCT specifications. Both A 35 records produced 306 hp and 400 Nm through a 7-speed Robotic gearbox. The A 45 records moved to an 8-speed Robotic gearbox and offered either 387 hp with 480 Nm or 421 hp with 500 Nm.
The second-generation restyling began in October 2022 and is also a Sedan. Its three catalogue records comprise two A35 2.0 DCT specifications, both with 306 hp and 400 Nm, and one A45 2.0 DCT with 421 hp and 500 Nm. All three use an 8-speed Robotic gearbox and AWD. Compared with the preceding A 35 records, the restyled A35 retains the same power and torque but gains one gearbox ratio. The quickest restyled A45 cuts the zero-to-100 km/h time from 3.9 to 3.7 seconds compared with the earlier 421 hp A 45.

Calculated from the catalogue figures, the 306 hp specifications produce about 153.7 hp per litre. The 360 hp 2.0 DCT reaches about 180.8 hp per litre, the 381 hp A45 2.0 DCT about 191.4 hp per litre, and the 387 hp A 45 2.0 DCT about 194.4 hp per litre. The 421 hp A 45/A45 specifications lead at about 211.5 hp per litre. Because displacement is identical throughout, these comparisons directly show how much output each specification extracts from the same engine capacity.

The performance advantage of the 421 hp second-generation A 45 2.0 DCT over its 306 hp A 35 counterparts is substantial: it has 115 hp and 100 Nm more, reaches 100 km/h 0.8–0.9 seconds sooner, and has a top speed 20 km/h higher. Its listed combined consumption is also 1.0–1.1 L/100 km greater.
Within the restyled second generation, the 421 hp A45 2.0 DCT again adds 115 hp and 100 Nm over either 306 hp A35 2.0 DCT. It accelerates to 100 km/h 1.0–1.1 seconds sooner and reaches a top speed 20 km/h higher. Its 9.2 L/100 km combined figure is 0.6–0.7 L/100 km above the two A35 records. City and highway consumption were not measured for any of these restyled versions.
Mercedes A-Class AMG dimensions, weight and wheels
Exterior dimensions are not measured in the supplied data. The available size-related figures are kerb weight, gross weight, ground clearance, fuel-tank capacity and, for one specification, wheel sizes.
| Generation and version | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|
| First generation — 2.0 DCT | 1,555 kg | 2,050 kg | not measured | 56 L | not measured |
| First-generation restyling — A45 2.0 DCT | 1,555 kg | 2,050 kg | 112 mm | 56 L | not measured |
| Second generation — A 35 2.0 DCT (306 hp, 4.8 seconds) | 1,570 kg | 2,080 kg | not measured | 51 L | not measured |

| Second generation — A 45 2.0 DCT (387 hp) | 1,545 kg | 2,080 kg | not measured | 51 L | not measured |
| Second-generation restyling — A35 2.0 DCT (4.8 seconds) | not measured | not measured | not measured | not measured | not measured |
| Second-generation restyling — A35 2.0 DCT (4.7 seconds) | 1,645 kg | 2,120 kg | not measured | 51 L | 235/40 R18; 235/35 R19 |
| Second-generation restyling — A45 2.0 DCT | 1,680 kg | 2,130 kg | not measured | not measured | not measured |
Among versions with a measured kerb weight, the 421 hp second-generation A 45 2.0 DCT has the most favorable calculated weight-to-power figure at about 3.68 kg per hp. The restyled 421 hp A45 2.0 DCT is about 3.99 kg per hp, while the 387 hp A 45 2.0 DCT is also about 3.99 kg per hp. The first-generation 360 hp 2.0 DCT is about 4.32 kg per hp, and the restyled 381 hp A45 2.0 DCT is about 4.08 kg per hp. The measured 306 hp cars range from about 5.08 to 5.38 kg per hp.
Which Mercedes A-Class AMG version should you choose?
Choose the first-generation 2.0 DCT if the priority is the lowest measured combined consumption: its 7.1 L/100 km figure is the lowest in the catalogue, and it still provides 360 hp, 450 Nm and a 4.6-second zero-to-100 km/h time. The first-generation restyled A45 2.0 DCT is the stronger hatchback choice on performance, adding 21 hp and 25 Nm while reducing the acceleration time by 0.4 seconds. Its combined consumption rises by only 0.2 L/100 km in the supplied figures.
Choose a second-generation A 35 2.0 DCT if you want the Sedan body and place economy ahead of maximum output. Between its two 306 hp records, the 4.7-second car is 15 kg lighter and 0.1 second quicker, but its city, highway and combined figures are each 0.1 L/100 km higher than those of the 4.8-second car.
For maximum performance before the restyling, select the 421 hp A 45 2.0 DCT. Against the 387 hp version, it adds 34 hp and 20 Nm, trims 0.1 second from the zero-to-100 km/h time, and raises top speed from 250 to 270 km/h. Both have the same listed city, highway and combined consumption figures, although the 421 hp car is 5 kg heavier.
The restyled A35 2.0 DCT makes sense when an 8-speed Robotic gearbox matters more than outright acceleration. Its 306 hp and 400 Nm match the preceding A 35, while combined consumption rises to 8.5 or 8.6 L/100 km. Of the two restyled A35 records, the 4.7-second specification is the better-documented one because its 1,645 kg kerb weight, 2,120 kg gross weight, 51 L tank and 235/40 R18 or 235/35 R19 wheels are measured; those values are not measured for the other record.
Choose the restyled A45 2.0 DCT for the fastest result in the entire dataset. Its 421 hp, 500 Nm, 3.7-second zero-to-100 km/h time and 270 km/h top speed lead the listed range. The trade-off visible in the data is its 9.2 L/100 km combined consumption, which is the highest measured figure here, as well as a 1,680 kg kerb weight. Prices, MSRP, engine-oil requirements, engine-management-light diagnoses, reliability findings and offers for sale cannot be compared because none of those items is measured in the supplied catalogue data.
