Stop buying diesel.
Start banking the difference.
Every kilometre a diesel truck drives, it burns money. A BYD electric truck doesn't. Below is the proof — and a live model you can run on your own fleet. Every input is labelled sourced or estimate; nothing is hidden.

The EV is cheaper to buy than a new diesel
At the launch promotional price the BYD undercuts or closely matches a new diesel — the T4 lists below the Isuzu QMR77F, the T5's small premium over the NQR75L is repaid in months on running cost. The honest contest is the cheap used diesel market, where the running-cost saving pays the price gap back in the months shown above.
Every input, on the table
What's sourced with a citation, and what's still an estimate to confirm — so the model can be audited line by line.
| Input | Value | Status |
|---|---|---|
| Cambodia retail diesel | $1.17 / L | sourced dailyfuels, 22 Jun 2026 (band $1.17–$2.00) |
| EDC commercial electricity | $0.158 / kWh | sourced EDC large-enterprise — confirm 2026 rate |
| BYD T4 energy use | 18.5 kWh/100km | sourced BYD T4 spec (5.5 km/kWh) |
| Isuzu QMR77F fuel use | ~15 L/100km | sourced Fuelly/CarExpert (loaded) — confirm local spec |
| Isuzu NQR75L fuel use | ~14.8 L/100km | sourced 5-tonne class; confirm local spec |
| 0% commercial-EV import duty | 0% | sourced Cambodia commercial-EV duty — confirm tariff line |
| BYD T5 energy use | 38 kWh/100km | estimate back-calc (band 34–48) — BYD to confirm |
| EV vs diesel maintenance | 60% of diesel | estimate ICCT/DOE benchmark — confirm BYD service quote |
| Diesel maintenance + tyres | $0.034–0.067/km | estimate ATRI-scaled — confirm Isuzu Cambodia |
The defensible claim: on energy alone (sourced inputs only) the T4 is ~84% and the T5 ~65% cheaper. With maintenance included and anchored to the ICCT/DOE benchmark, total running-cost saving is T4 ~76% and T5 ~59–62% — presented as a range, not a single point. Every TCO/payback figure assumes $0 resale on both the EV and the diesel (no used-EV-truck market in Cambodia yet).
