Aion HT

Aion HT: Which Version Should You Buy?

The Aion HT range in the supplied catalogue consists of two electric versions, both named AT. To distinguish them accurately, this article identifies them by output: AT (245 hp) and AT (340 hp). Both are RWD, use an Automatic gearbox with 1 ratio, and belong to the same 1 generation SUV 5-doors produced from October 2023 onward.

The Aion HT range in the supplied catalogue consists of two electric versions, both named AT. To distinguish them accurately, this article identifies them by output: AT (245 hp) and AT (340 hp). Both are RWD, use an Automatic gearbox with 1 ratio, and belong to the same 1 generation SUV 5-doors produced from October 2023 onward. The choice is therefore straightforward: AT (245 hp) offers the lower gross weight and known wheel sizes, while AT (340 hp) provides 95 hp and 115 Nm more, reaches 100 km/h 1 second sooner, and has a measured top speed of 183 km/h.

Aion HT generations and version choice

The Aion HT has 1 generation in the supplied data. The 1 generation started in October 2023 and has no recorded end date. It uses the SUV 5-doors body and includes 2 versions: AT (245 hp) and AT (340 hp). No restyling or later generation is listed, so there is no generation-to-generation change to compare. Searches for an Aion HT 2026 may refer to the continuing model, but the supplied information records only the October 2023 start date and no stop date.

Because both versions arrived at the same time and share the same body, fuel type, gearbox, drive layout, suspension design and brake arrangement, output and measured performance are the main deciding factors. Price is not available, so the extra cost of the stronger version and its value for money cannot be calculated from the catalogue data.

Aion HT specs and electric powertrain comparison

The AT (340 hp) has 95 hp and 70 kW more than the AT (245 hp). Its 430 Nm output is 115 Nm higher than the 315 Nm figure of the less powerful version. Expressed as relative differences, the stronger version provides about 39% more horsepower and about 37% more torque.

Power per litre cannot be calculated for either Aion HT because displacement is not measured. Cylinder count, cylinder layout and boost are also not measured. These omissions should not be interpreted as different configurations: the catalogue simply supplies no figures for those parameters.

Both versions use Electro fuel, an Automatic gearbox with 1 ratio, and RWD. They also share Independent, spring front and rear suspension, Ventilated disc front brakes, and Disc rear brakes. Consequently, the AT (340 hp) does not buy a different listed gearbox, drive system, suspension type or brake specification; its documented advantage is the higher motor output and stronger measured performance.

Aion HT performance, top speed and economy

The AT (340 hp) reaches 100 km/h in 5.8 seconds, compared with 6.8 seconds for the AT (245 hp). That makes the stronger version exactly 1 second quicker in the measured acceleration test. Its top speed is recorded as 183 km/h, whereas top speed for the AT (245 hp) is not measured, so no valid top-speed difference can be calculated.

City, highway and combined consumption are not measured for either version. No battery-consumption or driving-range figures are provided, so an economy or range winner cannot be identified. The recorded CO₂ value is 0 for both versions.

For buyers prioritizing acceleration, the AT (340 hp) is the clear choice: it combines 340 hp and 430 Nm with the faster 5.8-second result. Buyers who do not need that additional output can select the AT (245 hp), but the data does not establish whether it is more economical because comparable consumption figures are not measured.

Aion HT dimensions, weight and wheel sizes

Exterior dimensions and overall vehicle size are not measured in the supplied catalogue data. Kerb weight and ground clearance are also not measured for either version. Gross weight is available and provides the only direct weight comparison.

The AT (245 hp) has a gross weight of 2,580 kg, which is 100 kg below the 2,680 kg figure for the AT (340 hp). Kerb weight is not measured, so conventional kerb-weight-per-horsepower figures cannot be calculated.

Using gross weight only, the AT (340 hp) has approximately 7.88 kg per horsepower, while the AT (245 hp) has approximately 10.53 kg per horsepower. The stronger model therefore carries about 2.65 fewer gross kilograms per horsepower. This is a calculated comparison based on gross weight, not a substitute for a kerb-weight power-to-weight ratio.

Wheel sizes of 235/55 R19 and 245/55 R19 are recorded for the AT (245 hp). Wheel sizes for the AT (340 hp) are not measured, so the available data does not support a direct wheel comparison. Tank capacity is not measured for either version.

Which Aion HT version should you choose?

Choose the AT (340 hp) if acceleration and output matter most. Compared with the AT (245 hp), it adds 95 hp and 115 Nm, reduces the 0–100 km/h time by 1 second, and includes a measured 183 km/h top speed. It also has the better gross-weight-per-horsepower calculation despite carrying 100 kg more gross weight.

Choose the AT (245 hp) if 245 hp, 315 Nm and a 6.8-second 0–100 km/h time meet your needs. It has the lower 2,580 kg gross weight, and it is the only version for which wheel sizes are recorded: 235/55 R19 and 245/55 R19. However, the available data does not prove that it consumes less energy, travels farther, costs less or offers better value, because consumption, range and price are not measured.

In short, the AT (340 hp) is the performance-led purchase, while the AT (245 hp) is the lower-output, lower-gross-weight alternative. There is no documented difference in body style, fuel label, gearbox, drive, suspension or brake type, and there is no second generation to consider. Without price data, it is impossible to say what the additional performance costs; the measurable return is 95 hp, 115 Nm and a 1-second improvement to 100 km/h.
