The top speed of a Smart car in Europe depends on the specific model and powertrain. Generally, you can expect a range between 130 km/h (81 mph) for the basic electric models to 155 km/h (96 mph) for the performance-oriented gasoline versions. This speed is more than sufficient for European roads, where the design priority for these compact city cars is agility and efficiency, not high-speed autobahn cruising.
The most common models, like the current Smart EQ Fortwo and Forfour, are electronically limited to a top speed of 130 km/h (81 mph). This limit is set to maximize driving range, as sustaining high speeds drains the battery rapidly. For context, the official WLTP (Worldwide Harmonised Light Vehicles Test Procedure) range for these EVs is around 140-150 km, but this can drop significantly at sustained speeds over 100 km/h.
Earlier gasoline-powered Smart models, such as the Fortwo with a 1.0-liter engine, could reach slightly higher speeds. The table below outlines the top speeds for various Smart models sold in Europe.
| Smart Model | Powertrain | Top Speed (km/h) | Top Speed (mph) |
|---|---|---|---|
| Smart EQ Fortwo/Forfour | Electric | 130 | 81 |
| Smart Fortwo (451) 1.0L | Gasoline | 145 | 90 |
| Smart Fortwo (453) Brabus | Gasoline Turbo | 155 | 96 |
| Smart Roadster | Gasoline | 175 | 109 |
| Smart Fortwo ED (3rd Gen) | Electric | 125 | 78 |
While a Smart car can technically reach these speeds, it's not its natural habitat. The vehicle's short wheelbase and tall stance can make it feel less stable and more susceptible to crosswinds at high speeds compared to larger, heavier sedans. The primary strength of a Smart is its unparalleled maneuverability in dense urban environments, where its tiny turning circle and compact size are true advantages. For safe high-speed travel on European motorways, a larger, more stable vehicle is generally recommended.

My Smart ForTwo electric tops out at 130 km/h on the speedometer. I've had it up to that on the autobahn a few times, but it's not a relaxing experience. The battery gauge drops noticeably, and you feel every gust of wind. It’s honestly a bit noisy and jittery. I bought it for zipping around Munich, not for road trips. In the city, it’s perfect. On the highway, it’s just keeping up.
