On the other hand, the smart #3 is slightly longer at 4400 mm, wider at 1844 mm, and higher at 1556 mm. This additional size translates into a more robust aesthetic and a slightly more spacious cabin. When it comes to cargo space, the #3 offers 370 liters, making it slightly less practical than the Fiat for storage—but still competitive for a city SUV.

Its 0-100 km/h acceleration varies from a respectable 8.5 seconds to 10.5 seconds, depending on the engine option, making it agile enough for city driving.

In contrast, the smart #3 is exclusively electric, available with power outputs of up to 428 hp. With a sharp emphasis on performance, it can sprint from 0-100 km/h in as little as 3.7 seconds, which is significantly quicker than the Fiat. The rear-wheel drive or optional all-wheel drive arrangement provides excellent handling, making it a joy on both city streets and open roads.

#3

The Fiat 600 offers a battery capacity of 51 kWh, with an impressive electric range of up to 409 km. The petrol variant achieves a consumption rate of 4.8 L/100 km, showcasing its efficiency for combustion engine lovers.

Meanwhile, the smart #3 comes with two battery options: 47 kWh and 62 kWh, enabling a maximum electric range between 325 km and 455 km. While the consumption for the smart #3 varies—ranging from 16.3 kWh/100 km to 17.2 kWh/100 km—it offers a zero-emission drive, truly embodying sustainability. Both models achieve an 'A' rating for CO2 efficiency, confirming their eco-conscious designs.

Technological Innovations

The smart #3 goes a step further with its focus on digital innovation. Boasting cutting-edge connectivity features, a high-performance infotainment system, and an array of smart safety technologies, this SUV is tailored for a more connected driving experience.
