Vehicle purchase price is only one part of the fleet equation. The meaningful comparison combines energy, maintenance, insurance, residual value, utilization, and the operational requirements around fueling or charging. This model compares a diesel Sprinter and Mercedes eSprinter over eight years using a high-roof 170WB vehicle operating 85 miles per day, 260 days per year.
Scenario assumptions
| Item | Diesel Sprinter | Mercedes eSprinter |
|---|---|---|
| Purchase price | $60,000 | $75,000 |
| Energy assumption | $6.00/gallon at 18 MPG | $0.50/kWh at 0.42 kWh/mile |
| Annual operating distance | 22,100 miles | |
| Annual energy cost | $7,367 | $4,641 |
| Year-one maintenance | $4,200, growing 8% annually | $2,100, growing 5% annually |
| Annual insurance | $3,200 | $3,400 |
| Residual value at year eight | 18% of purchase price | 22% of purchase price |
What the model shows
Under these assumptions, the eSprinter’s cumulative cost is lower from Year 1 onward, even with its higher initial purchase price. Annual savings increase as the diesel vehicle’s maintenance cost grows more quickly.
| Year | Diesel annual cost | eSprinter annual cost | EV annual savings |
|---|---|---|---|
| 1 | $22,267 | $19,516 | $2,751 |
| 2 | $22,603 | $19,621 | $2,982 |
| 3 | $22,966 | $19,731 | $3,235 |
| 4 | $23,358 | $19,847 | $3,511 |
| 5 | $23,781 | $19,969 | $3,812 |
| 6 | $24,238 | $20,096 | $4,142 |
| 7 | $24,732 | $20,230 | $4,502 |
| 8 | $25,265 | $20,371 | $4,894 |
Eight-year result
The model produces a gross eight-year cost of $189,210 for the diesel Sprinter and $159,381 for the eSprinter. After estimated residual values of $10,800 for diesel and $16,500 for the eSprinter, net eight-year total cost of ownership is $178,410 for diesel and $142,881 for the eSprinter. The illustrative EV savings are therefore $35,529 over the eight-year period.
What this does—and does not—answer
A TCO model is a decision tool, not a universal price promise. The result changes with fuel and electricity rates, duty cycle, route length, charging availability, vehicle price, incentives, maintenance experience, insurance, financing, residual value, and downtime. The eSprinter battery warranty in this model ends after Year 8; fleets planning to operate beyond that point should budget for potential battery replacement in the $15,000–$22,000 range.
The operational question is equally important. A fleet that loses productive time sending drivers to fuel, schedule service, wash vehicles, or find public charging may have a higher real cost than a spreadsheet initially shows. Fleet as a Service is designed to address that work by combining vehicles, charging, parking, maintenance coordination, and operating visibility.
This analysis is based on the supplied EVODS comparison model and its stated assumptions. Fleet teams should validate current vehicle pricing, energy rates, incentives, route requirements, and warranty terms before making a procurement decision.
