Cost per km, the fleet metric
At ₫36.5M annual saving against the ₫28M unit price, every U-1 returns its own capital in under 10 months, then saves at the same rate for the rest of its life. All-in ₫/km includes energy, maintenance, depreciation, and insurance over 62,400 km/year.
Sensitivity: saving per unit vs fuel price
Annual saving per unit at different RON92 prices, all else held constant. The saving is floored, not capped.
RON92 at ₫22,000/L, low case₫31.1M/year
RON92 at ₫25,000/L, basis₫36.5M/year
RON92 at ₫30,690/L, March 2026 spike₫46.7M/year
RON92 at ₫35,000/L, stress case₫54.3M/year
Even in the low fuel case the unit still saves ₫31.1M/year, a 12 month payback. Fuel upside accrues entirely to the operator because the subscription is fixed.
Assumptions and exclusions
What this model does and does not include
- Financing costs excluded on both sides. Leasing or loan structures change cash flow timing, not the underlying cost gap.
- EV registration incentives excluded. Where fee exemptions apply they improve the Volty case further; we keep the comparison conservative.
- Residual values are estimates. The used market for electric two wheelers is young; depreciation lines will firm up with fleet data.
- BaaS pricing reflects current partner terms and is contractual per agreement, not a permanent market price.
- Insurance held equal across both vehicles, and downtime is valued at ₫400,000 per offline day.
- Unit price is indicative. ₫28,000,000 reflects fleet launch pricing; final pricing is set per fleet agreement.
