Smart #1: Which Version Should You Buy?
The Smart #1 catalogue contains two electric versions, both named AT, so they must be distinguished by output: AT (272 hp) and AT (428 hp). Both belong to the model’s only generation, in production since April 2022, and both use the SUV 5-doors body.
The Smart #1 catalogue contains two electric versions, both named AT, so they must be distinguished by output: AT (272 hp) and AT (428 hp). Both belong to the model’s only generation, in production since April 2022, and both use the SUV 5-doors body. The central buying decision is therefore straightforward: the AT (272 hp) prioritizes lower weight and already strong performance, while the AT (428 hp) adds 156 hp, 234 Nm, AWD, and much quicker acceleration. Price data is not available, so this comparison explains what the more powerful specification adds without claiming how much it costs.
Smart #1 generations: can you choose between generations?
There is only one Smart #1 generation in the supplied catalogue. It began production in April 2022 and has no recorded end date. This generation uses an SUV 5-doors body and contains two versions: AT (272 hp) and AT (428 hp).
Consequently, there is no earlier or later Smart #1 generation to compare here, and no recorded restyling separates the two cars. The meaningful choice is between their power, torque, drive system, acceleration, and weight—not between model generations.
Smart #1 engine and EV specs compared
Both Smart #1 versions are electric, so a conventional engine-size comparison does not apply. Displacement, cylinder count, cylinder layout, and boost are all not measured in the supplied data. Power per litre also cannot be calculated because neither version has a measured displacement.
| Exact version name | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| AT (272 hp) | 272 hp / 200 kW | 350 Nm | not measured | Electro | not measured | not measured | not measured | Automatic, 1 speed | RWD |
| AT (428 hp) | 428 hp / 314 kW | 584 Nm | not measured | Electro | not measured | not measured | not measured | Automatic, 1 speed | AWD |
The AT (428 hp) has 156 hp and 234 Nm more than the AT (272 hp). That represents approximately 57% more horsepower and 67% more torque. It also changes the drive system from RWD to AWD. These are the clearest specification gains attached to choosing the more powerful Smart #1.
The AT (272 hp) should not be treated as a mechanically similar car with only a small output reduction. Its 350 Nm output and RWD configuration define a materially different specification from the 584 Nm, AWD alternative.
Smart #1 performance, acceleration, and economy
| Exact version name | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| AT (272 hp) | 6.7 seconds | 180 km/h | not measured | not measured | not measured | 0 |
| AT (428 hp) | 3.9 seconds | 180 km/h | not measured | not measured | not measured | 0 |
The AT (428 hp) reaches 100 km/h 2.8 seconds sooner than the AT (272 hp). In relative terms, its recorded acceleration time is about 42% shorter. This is the strongest numerical reason to choose the higher-output version.
Top speed does not separate the two: both are rated at 180 km/h. The additional 156 hp therefore produces a major improvement in acceleration without increasing the recorded maximum speed.
City, highway, and combined consumption are not measured for either AT version. Battery capacity, driving range, and charging figures are also not measured in the supplied data, so no evidence-based economy or range advantage can be assigned to either one. Likewise, engine sound cannot be compared from these specifications.
Smart #1 dimensions and weight
Exterior length, width, height, and mirror-inclusive width are not measured in the supplied data. Ground clearance and wheel sizes are also not measured for both versions. Because the Smart #1 uses Electro fuel, a conventional fuel-tank figure is not measured.
| Exact version name | Kerb weight | Gross weight | Gross-minus-kerb difference | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|---|
| AT (272 hp) | 1,770 kg | 2,140 kg | 370 kg | not measured | not measured | not measured |
| AT (428 hp) | 1,900 kg | 2,325 kg | 425 kg | not measured | not measured | not measured |
The AT (428 hp) is 130 kg heavier at kerb weight and 185 kg heavier at gross weight. Its gross-minus-kerb difference is 425 kg, which is 55 kg greater than the 370 kg difference for the AT (272 hp). This subtraction is not a dedicated payload rating, but it clearly shows the gap between the two recorded mass figures.
Measured against output, the AT (272 hp) carries about 6.51 kg per horsepower, whereas the AT (428 hp) carries about 4.44 kg per horsepower. The more powerful version therefore has approximately 32% less kerb weight per horsepower, despite its higher absolute weight.
The same pattern appears when power is expressed in kilowatts: the AT (272 hp) has 8.85 kg per kW, while the AT (428 hp) has approximately 6.05 kg per kW. The additional mass is much smaller proportionally than the increase in output.
Smart #1 suspension and brake specs
Both versions use Independent, spring suspension at the front and rear. Both also have Ventilated disc front brakes and Disc rear brakes. Based on the supplied catalogue fields, suspension and brake type do not provide a reason to favor one version.
| Exact version name | Front suspension | Rear suspension | Front brakes | Rear brakes |
|---|---|---|---|---|
| AT (272 hp) | Independent, spring | Independent, spring | Ventilated disc | Disc |
| AT (428 hp) | Independent, spring | Independent, spring | Ventilated disc | Disc |
Which Smart #1 version should you choose?
Choose the AT (272 hp) if lower kerb weight, RWD, and adequate acceleration matter more than maximum output. At 1,770 kg, it is 130 kg lighter than the other version, yet it still produces 272 hp and 350 Nm and reaches 100 km/h in 6.7 seconds. Its top speed is the same 180 km/h as the more powerful car, so buyers focused on the recorded maximum speed gain nothing by moving up.
Choose the AT (428 hp) if acceleration, torque, AWD, and power-to-weight performance are the priorities. It delivers 428 hp and 584 Nm, reaches 100 km/h in 3.9 seconds, and has approximately 4.44 kg per horsepower. Compared with the AT (272 hp), it adds 156 hp and 234 Nm while increasing kerb weight by 130 kg.
The AT (428 hp) is therefore the stronger performance choice: it cuts 2.8 seconds from the 0–100 km/h time and adds AWD. The AT (272 hp) is the more restrained choice: it preserves the shared 180 km/h top speed while carrying less mass.
A value-for-money winner cannot be named because Smart #1 price data is not provided. Range, battery, charging, consumption, interior equipment, reliability, and problem records are also not measured, so none should be used to manufacture a recommendation. On the available numbers alone, the decision is between the lighter AT (272 hp) and the substantially quicker, higher-torque AT (428 hp).
