MG 4: which version to buy — specs compared

If the question is which MG 4 to buy, the catalogue data split the answer into two generations and seven named versions: five first-generation AT electric variants (170 hp, 190 hp, 204 hp, 245 hp, 435 hp) and two second-generation cars (AT Long 163 hp and AT 163 hp). All use Electro fuel, an Automatic 1-speed gearbox, and a SUV 5-doors body.

If the question is which MG 4 to buy, the catalogue data split the answer into two generations and seven named versions: five first-generation AT electric variants (170 hp, 190 hp, 204 hp, 245 hp, 435 hp) and two second-generation cars (AT Long 163 hp and AT 163 hp). All use Electro fuel, an Automatic 1-speed gearbox, and a SUV 5-doors body. Displacement, cylinders, cylinder layout, and boost are not measured on every version, so there is no power-per-litre figure to compute. What can be compared is horsepower, torque, 0–100, top speed, drive, kerb weight, payload, and (where listed) wheel size.

This is the MG 4 EV, not an MG 42 firearm: searches for “mg 4 car”, “mg 4 specs”, “mg 4 ev horsepower”, and “mg 4 xpower specs” map onto these seven rows.

Generations: what actually changed

1 generation (from 2022-06-01, no end date in the data) is a SUV 5-doors with 5 versions, all named AT. Four start in June 2022; the 435 hp AT starts later, 2023-07-01. Front suspension is Independent, spring; rear is Independent, spring. Front brakes are Ventilated disc; rear are Disc. Drive is FWD on four versions and AWD only on the 435 hp AT. Kerb weight sits between 1710 kg and 1800 kg.

2 generation (from 2025-07-01, no end date) is the same SUV 5-doors body type but only 2 versions: AT Long and AT, both 163 hp / 119 kW / 250 Nm, Electro, Automatic, 1 speed, FWD. Versus the lightest first-generation AT (1710 kg at 170 hp), the second-generation AT is 1415 kg — 295 kg lighter (−17.3%). Peak power drops from the first-generation range of 170–435 hp to 163 hp (−7 hp vs the weakest first-gen AT, −272 hp vs the strongest). Rear suspension on the second-generation AT is labelled Semi-independent, springorts hélicoïdaux, sem, not Independent, spring. AT Long has no measured 0–100, top speed, or weights, so it cannot be ranked on those axes.

Same name AT appears six times; the distinguishing keys in this catalogue are horsepower (and generation). AT Long is the only unique name.

Horsepower, torque, and kg per hp

There is no engine size in litres, so power per litre is not measured. Weight per horsepower uses kerb mass where it exists.

1 generation AT 170 hp: 1710 kg ÷ 170 hp = 10.06 kg/hp. Torque 254 Nm. Weakest first-gen power, heaviest kg/hp among measured first-gen cars.

1 generation AT 190 hp: 1765 kg ÷ 190 hp = 9.29 kg/hp. Torque 357 Nm103 Nm more than the 170 hp and 204 hp AT rows (254 Nm), despite only 20 hp more than 170 and 14 hp less than 204. If the buying criterion is pulling force at the listed peak, this AT beats the 204 hp AT on newton-metres.

1 generation AT 204 hp: 1726 kg ÷ 204 hp = 8.46 kg/hp. Torque 254 Nm — identical to the 170 hp AT, +34 hp and +16 kg kerb vs that car. Power density is better than 170/190; torque is not.

1 generation AT 245 hp: 1755 kg ÷ 245 hp = 7.16 kg/hp. Torque 350 Nm (−7 Nm vs 190 hp AT, +96 Nm vs 170/204). +75 hp vs 170, +41 hp vs 204, +55 hp vs 190. Best first-gen FWD power-to-weight in this set.

1 generation AT 435 hp: 1800 kg ÷ 435 hp = 4.14 kg/hp. Torque 600 Nm. Versus the 170 hp AT: +265 hp (2.56×), +346 Nm (2.36×), +90 kg kerb. Only AWD MG 4 in the data. Versus the 245 hp AT: +190 hp, +250 Nm, +45 kg.

2 generation AT 163 hp: 1415 kg ÷ 163 hp = 8.68 kg/hp — lighter kg/hp than first-gen 170 and 190 hp AT, heavier kg/hp than 204 / 245 / 435. Torque 250 Nm (−4 Nm vs first-gen 170/204).

2 generation AT Long 163 hp: same 163 hp / 119 kW / 250 Nm as the second-gen AT. Kerb weight not measured, so kg/hp not measured. The name is the only catalogue difference you can use without inventing battery or range figures (those are not in the data).

Performance and economy (mpg / 0–100)

City, highway, and combined consumption: not measured on every version. Tank: not measured. CO2 is 0 on all seven. There is no mpg number to rank.

0–100 km/h and top speed:

Top-speed bands: 200 (435 only), 180 (190 and 245), 160 (170, 204, second-gen AT). Ground clearance: not measured for all.

Dimensions, weight, wheels

Overall length/width/height: not measured (searches for “mg 4 dimensions” and “mg 4 size” cannot be answered in millimetres from this dataset). What is measured is mass and, on two versions, tyres.

Payload (gross − kerb):

AT Long 163 hpnot measurednot measurednot measured

The 190 hp AT has the smallest listed payload (348 kg). The 435 hp AT has the largest (461 kg), then 245 hp AT (448 kg), then second-gen AT (435 kg). Second-gen AT is the lightest car (1415 kg kerb, 1850 kg gross) — 295 kg less kerb than first-gen 170 hp AT, 385 kg less than 435 hp AT.

Wheels: not measured except AT 245 hp (215/50 R17, 235/45 R18) and second-gen AT (195/60 R16, 205/50 R17). Second-gen listed rubber is narrower (195/205 vs 215/235).

Which version to choose

Use the numbers; there are no prices, so “extra money” here means extra hp, Nm, seconds, kilograms, and drive, not currency.

Choose 1 generation AT 435 hp if the job is acceleration, top speed, and the only AWD layout. It is 2.56× the power of the 170 hp AT, 4.14 kg/hp versus 10.06, 0–100 3.8 s versus 7.7 s (3.9 s faster), top speed 200 versus 160 (+40 km/h). Versus 245 hp AT: +190 hp, +250 Nm, −2.7 s to 100, +20 km/h, AWD instead of FWD, +45 kg kerb. It is the heaviest (1800 / 2261 kg). It is the only first-gen version that starts in 2023-07-01 rather than 2022-06-01.

Choose 1 generation AT 245 hp if you stay FWD and want the quickest first-gen front-drive sprint (6.5 s) and 180 km/h without jumping to 435 hp AWD. It is 1.0 s quicker than 190 hp AT and 1.4 s quicker than 204 hp AT. Payload 448 kg is second only to 435. It is the only first-gen row with listed wheels (R17/R18). kg/hp 7.16 is the best FWD figure.

Choose 1 generation AT 190 hp if torque at the listed peak matters more than peak hp: 357 Nm beats 204 hp AT by 103 Nm and beats 245 hp AT by 7 Nm, while 0–100 (7.5 s) is 0.4 s quicker than 204 hp AT. Top speed matches 245 at 180. Payload is the worst measured (348 kg). Kerb 1765 kg is mid-pack.

Choose 1 generation AT 204 hp only if the 150 kW / 204 hp figure itself is the requirement. It does not win 0–100 (slowest first-gen at 7.9 s), does not win torque (254 Nm, tied with 170), and tops out at 160 km/h like the 170 hp AT. What it does win among the three “small” first-gen cars is kg/hp (8.46 vs 9.29 and 10.06) and payload vs 170/190 (387 kg).

Choose 1 generation AT 170 hp if the target is the lowest first-gen horsepower and the lightest first-gen kerb among the 2022 AT set that still has a full performance row: 1710 kg, 7.7 s, 160 km/h, 254 Nm. It is 20 hp and 103 Nm down on 190, 2.0 s slower to 100 than 245, and 265 hp down on 435.

Choose 2 generation AT 163 hp if kerb mass is the ranking rule: 1415 kg, 295 kg below the lightest first-gen AT. Payload 435 kg is close to 245 hp AT (448) despite 340 kg less kerb than that car. The trade: 163 hp (−7 to −272 vs first gen), 9.5 s 0–100 (slowest measured), 160 km/h, FWD only, rear suspension Semi-independent, springorts hélicoïdaux, sem instead of first-gen Independent, spring, smaller listed wheels. This is the 2025-07-01 AT, not the first-gen cars of the same name.

Choose 2 generation AT Long 163 hp only for the AT Long name and the same 163 hp / 250 Nm / FWD / Electro / Automatic package. 0–100, top speed, kerb, gross, wheels: not measured. You cannot prove it is quicker, slower, lighter, or heavier than second-gen AT from this table.

Between generations, in one line: first generation buys a power spread from 170 to 435 hp and 0–100 from 7.9 to 3.8 s, with AWD at the top; second generation buys 163 hp, a 1415 kg AT, and an AT Long whose dynamics are not measured. None of the seven have a measured engine displacement, fuel tank, ground clearance, or consumption figure — those searches stay unanswered here on purpose, because the data does not contain them.
