Side-by-Side Specs
| Spec | Lexus RZ | Volvo EX30 |
|---|---|---|
| Compared variant | 350e | Single Motor Extended Range |
| Battery (approx.) | ~72 kWh | ~65 kWh |
| WLTP range (rated) | ~575 km | ~476 km |
| Efficiency (approx.) | ~180 Wh/km | ~178 Wh/km |
| DC fast charging (published) | up to 150 kW | up to 158 kW |
| 10-80% charge time (approx.) | ~30 min | ~28 min |
| Max AC charging | up to 22 kW | up to 11 kW (22 kW optional) |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Volvo EX30 has the higher published DC charging figure at 158 kW, which is roughly 5% higher than the Lexus RZ at 150 kW. In practice, that figure 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 published fast-charge window, the Volvo EX30 is listed at about 28 minutes, which is 2 minutes quicker than the Lexus RZ at 30 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Lexus RZ has a WLTP rated range of approximately 575 km, which is roughly 99 km more than the Volvo EX30 at approximately 476 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 Volvo EX30 consumes 178 Wh/km, compared to 180 Wh/km for the Lexus RZ. That means the Volvo EX30 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 Lexus RZ has approximately 72 kWh of useable battery , while the Volvo EX30 has approximately 65 kWh.
Which One Should You Choose?
If fast charging is your priority, the Volvo EX30 has the higher published DC figure (up to 158 kW) and the shorter published charge time at approximately 28 minutes. For long road trips, published stop time matters more than the headline kW number alone.
Both cars support 22 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 Volvo EX30 is the more efficient choice at 178 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Lexus RZ has a WLTP rated range of approximately 575 km, which is roughly 99 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.
