Lexus RZ vs Smart #3

Side-by-Side Specs

Charging Speed

The Smart #3 has the higher published DC charging figure at 150 kW, which is comparable to 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 Smart #3 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 160 km more than the Smart #3 at approximately 415 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 Smart #3 consumes 175 Wh/km, compared to 180 Wh/km for the Lexus RZ. That means the Smart #3 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 Smart #3 has approximately 62 kWh.

Which One Should You Choose?

Both cars show similar published DC fast-charging figures at 150 kW. For road trips, the one with more range between stops may be more practical.

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 Smart #3 is the more efficient choice at 175 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 160 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
