Two rigids sit close together in the Dongfeng electric range, and fleet buyers regularly ask which one to order: the KTH3 with a CATL 400 kWh pack and a 450 kW (612 hp) LvKong motor, and the KT5L with a CATL 348 kWh pack and a LvKong e-axle. They overlap on paper, but they are engineered for different constraints — and choosing the wrong one is expensive in a way that shows up as an under-utilised asset rather than an obvious failure. This comparison sets out the decision.
| Parameter | KTH3 | KT5L |
|---|---|---|
| Battery | CATL LFP 400 kWh | CATL LFP 348 kWh |
| Motor | LvKong 450 kW (612 hp) | LvKong e-axle |
| Class | Heavy rigid | Medium rigid, long body |
| Strength | Power and payload | Load volume and body length |
| Body lengths | Standard heavy rigid bodies | From 7,700 mm upward |
| Typical use | Industrial freight, heavy regional trunk | Bulky regional distribution |
| Consumption | 0.95–1.20 kWh/km | 0.70–0.95 kWh/km |
| Realistic range | 300–380 km | 310–430 km (urban/suburban) |
| Battery warranty | 8 yr / 4,500 cycles to 80% SOH | 8 yr / 4,500 cycles to 80% SOH |
| Indicative FOB | USD 78,000–115,000 | USD 62,000–92,000 |
Almost every case resolves on one question. Work out your average load density:
Practical examples: furniture, appliances, packaging, textiles and empty-return packaging are cube-limited → KT5L. Beverages, building materials, paper, metal products and dense FMCG pallets are weight-limited → KTH3.
The two differ in depot planning more than buyers expect:
| Item | KTH3 | KT5L |
|---|---|---|
| Daily energy (250 km) | 240–300 kWh | 175–240 kWh |
| Overnight AC per bay | 44 kW recommended | 22–44 kW sufficient |
| Shared DC per trucks | 1 unit per 3 | 1 unit per 4 |
| Demand-charge exposure | Higher | Moderate |
Both benefit from smart load management above roughly six vehicles on one site. See smart charging load management and depot electrical planning.
On a 250 km regional route, 280 operating days per year:
The productivity difference comes from choosing the vehicle where it is not capacity-constrained: a KTH3 running cube-limited freight wastes energy, and a KT5L running weight-limited freight makes extra trips.
Vietnamese distribution combines dense urban delivery with fast-growing industrial park freight, and the two vehicles map cleanly onto that split. Our Vietnam market page covers import, deployment and support for Vietnamese fleets.

Choose the KTH3 for dense, heavy, hilly or long-distance regional work. Choose the KT5L for bulky, light, mixed urban-regional work where body length is the binding constraint. If your fleet does both, the correct answer is usually a mixed fleet with each vehicle on the duty it is engineered for — and a shared charging and telematics platform across both. Both carry the same CATL warranty: 8 years or 4,500 cycles to 80% state of health.
Three recurring errors account for most mis-specification between these two platforms, and all three are avoidable at quotation stage.
A simple pre-order exercise prevents all three: log two weeks of actual loads — mass, volume, route, and access constraints — then classify each load as mass-limited or volume-limited. The split tells you the fleet mix directly, and it is the same data you will need for the energy model. Our battery sizing methodology uses exactly this dataset, and the RFP guide shows how to turn it into a specification that suppliers can price accurately.
