Side-by-Side Specs
| Spec | BMW i4 | Rolls-Royce Spectre |
|---|---|---|
| Battery (approx.) | ~80.7 kWh | ~102 kWh |
| WLTP range (rated) | ~589 km | ~530 km |
| Efficiency (approx.) | ~157 Wh/km | ~219 Wh/km |
| Max DC charging | up to 207 kW | up to 195 kW |
| 10-80% charge time (approx.) | ~32 min | ~34 min |
| Max AC charging | up to 11 kW | up to 11 kW |

Charging Speed
The BMW i4 has a peak DC charging speed of 207 kW, which is roughly 6% faster than the Rolls-Royce Spectre at 195 kW. In practice, peak speed only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.
For the 10-80% charge (the most common DC fast charging scenario), the BMW i4 finishes in about 32 minutes, which is 2 minutes quicker than the Rolls-Royce Spectre at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BMW i4 has a WLTP rated range of approximately 589 km, which is roughly 59 km more than the Rolls-Royce Spectre at approximately 530 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.
Efficiency matters more than battery size for daily driving costs. The BMW i4 consumes 157 Wh/km, compared to 219 Wh/km for the Rolls-Royce Spectre. That means the BMW i4 uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.
A more efficient car does not always mean more range. Battery size plays a role too. The BMW i4 has approximately 80.7 kWh of useable battery , while the Rolls-Royce Spectre has approximately 102 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the BMW i4 wins on both peak power (up to 207 kW) and time at the plug (approximately 32 minutes from 10-80%). For long road trips with multiple charging stops, that faster turnaround makes a real difference.
Both cars support 11 kW AC charging, so home and workplace charging speeds will be similar.
If you mostly charge at home or at work and care more about daily driving costs, the BMW i4 is the more efficient choice at 157 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW i4 has a WLTP rated range of approximately 589 km, which is roughly 59 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
