Road load powertrain · driveline
| Fact | Value | Basis | Note |
|---|---|---|---|
| Test mass | 2359 kg | derived | Published curb mass plus the 300 lb EPA's loaded vehicle weight adds for occupants. |
| Frontal area | 4.60 m² | assumed | 0.85 of published width × height, a rule of thumb; nobody measured this vehicle's. |
| Drag coefficient | 0.40 | assumed | No published figure; an assumed value for a tall, square-fronted van. |
| Drag area (Cd·A) | 1.84 m² | modelled | The drag coefficient on the assumed frontal area. |
| Rolling resistance | 0.009 | assumed | Typical for light-truck tyres on smooth asphalt; not measured on this van. |
| Driveline efficiency | 90% | assumed | Gearbox and axle losses at cruise, a typical figure. |
| Power to hold 55 mph | 24 kW | modelled | Drag and rolling resistance on level road in still air at 20 °C, through the driveline efficiency. The catalog's EPA coastdown section, where it lists this model, measures road load instead. |
| Power to hold 70 mph | 45 kW | modelled | Drag and rolling resistance on level road in still air at 20 °C, through the driveline efficiency. The catalog's EPA coastdown section, where it lists this model, measures road load instead. |
Performance powertrain · driveline
| Fact | Value | Basis | Note |
|---|---|---|---|
| 5–60 mph | 8.5 s | modelled | Full throttle from rest on level road, through CRE8VIRTUAL's torque converter, on a full-load curve drawn through the published torque and power. Stall speed, shift time, lockup, tyre grip, axle load and inertias are assumed; nothing is fitted to a road test. |
| 0–30 mph | 4.0 s | modelled | A plain pull-away with no brake-torque launch, so it runs slower than a test track's time; the 5–60 is the better figure. |
| 0–60 mph | 9.1 s | modelled | A plain pull-away with no brake-torque launch, so it runs slower than a test track's time; the 5–60 is the better figure. |
| 5–60 mph at gross weight | 13.1 s | modelled | The same pull at the gross vehicle weight rating. |
| 0–60 mph at gross weight | 13.7 s | modelled | The same pull at the gross vehicle weight rating. |
| Engine speed at 70 mph | 1,573 rpm in gear 9 | modelled | Ratios and tyre radius with the converter locked, on the unloaded radius the size names. |
| Top speed on power | 116 mph in gear 5 | modelled | At test mass, where road load meets full power. Makers govern lower: both road-tested vehicles here are governed. |
| Grade held at 70 mph | 20.0% | modelled | The steepest grade held at that speed in the best gear at full throttle, with no altitude or heat derate. |
| Grade held at 70 mph, gross weight | 11.2% | modelled | The steepest grade held at that speed in the best gear at full throttle, with no altitude or heat derate. |

Wheel force and road load
Wheel force by gearRoad load
Not modelled yet
| System | Gap |
|---|---|
| powertrain | No spark-ignition combustion model: CRE8VIRTUAL's engine model is the OM651 diesel, so this engine stands on its published ratings. |
| powertrain | The 948TE's tooth counts are not published, so no gearbox model; its ratios stand as printed. |
| powertrain | No shift map, torque management or launch control: the performance layer shifts at rated speed under full throttle. |
| body | No published drag coefficient or measured frontal area, so road load runs on assumed values until a coastdown is read. |
| suspension | No spring or damper rates. |
| brakes | No brake bias or pad data. |
Model years
EPA's fuel-economy file lists no rows for this model. It covers light-duty vehicles; most vans and trucks over 8,500 lb GVWR are outside it.
EPA coastdown
no EPA coastdown is filed for that make and model; ingest `testcar` for its model years
