Side-by-Side Specs
| Spec | Smart #3 | Tesla Model Y |
|---|---|---|
| Battery (approx.) | ~62 kWh | ~75 kWh |
| WLTP range (rated) | ~415 km | ~586 km |
| Efficiency (approx.) | ~175 Wh/km | ~165 Wh/km |
| Max DC charging | up to 150 kW | up to 250 kW |
| 10-80% charge time (approx.) | ~28 min | ~27 min |
| Max AC charging | up to 22 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Tesla Model Y has a peak DC charging speed of 250 kW, which is roughly 67% faster than the Smart #3 at 150 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 Tesla Model Y finishes in about 27 minutes, which is 1 minutes quicker than the Smart #3 at 28 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Tesla Model Y has a WLTP rated range of approximately 586 km, which is roughly 171 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 Tesla Model Y consumes 165 Wh/km, compared to 175 Wh/km for the Smart #3. That means the Tesla Model Y 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 Tesla Model Y has approximately 75 kWh of useable battery , while the Smart #3 has approximately 62 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the Tesla Model Y wins on both peak power (up to 250 kW) and time at the plug (approximately 27 minutes from 10-80%). For long road trips with multiple charging stops, that faster turnaround makes a real difference.
For AC charging (home wallboxes, workplace chargers, and public street chargers), the Smart #3 supports up to 22 kW, compared to 11 kW for the Tesla Model Y. In Europe, many public chargers are 22 kW AC, so this difference can mean charging roughly twice as fast at those locations.
If you mostly charge at home or at work and care more about daily driving costs, the Tesla Model Y is the more efficient choice at 165 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Tesla Model Y has a WLTP rated range of approximately 586 km, which is roughly 171 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.
