The top speed of a 2015 car is electronically limited to 96 miles per hour (mph). This figure applies to the primary model available in the U.S. market for that year, the Smart Fortwo Electric Drive (ED). While sufficient for highway merging and passing, this speed is intentionally capped by the manufacturer for safety and efficiency reasons, reflecting the car's primary design purpose as an urban commuter vehicle, not a high-performance machine.
Driving a Smart car at or near its top speed is a unique experience. The car's short wheelbase and tall stance mean it feels less planted than a conventional sedan. You'll notice significant wind noise and a firm ride, as the chassis tuning is optimized for stability in city driving. The electric motor in the ED model provides instant torque for quick acceleration from a stop, but power tapers off significantly as you approach higher speeds.
The main factor limiting the Smart car's speed is its relatively low-power electric motor. For the 2015 model year, the Fortwo Electric Drive produced 74 horsepower and 96 lb-ft of torque. This is adequate for zipping through traffic but lacks the reserve power needed for sustained high-speed travel. Aerodynamics also play a role; the car's upright, boxy shape creates substantial drag, which the motor must work hard to overcome.
Here is a comparison of key performance data for the 2015 Smart Fortwo models:
| Model | Powertrain | Horsepower (hp) | Torque (lb-ft) | 0-60 mph Time (sec) | Top Speed (mph) |
|---|---|---|---|---|---|
| Fortwo Electric Drive | Electric Motor | 74 | 96 | 11.5 | 96 (electronically limited) |
| Fortwo Coupe | 1.0L 3-cylinder Gasoline | 70 | 68 | 13.0 | 90 (est.) |
| Fortwo Cabrio | 1.0L 3-cylinder Gasoline | 70 | 68 | 13.5 | 90 (est.) |
Is a 96 mph top speed a problem? For the vast majority of owners, absolutely not. The car excels in its intended environment: dense urban areas with lower speed limits. Attempting to drive at maximum speed for extended periods will drastically reduce the Electric Drive model's driving range and is not recommended from a safety or efficiency standpoint.

Honestly, you don't buy a 2015 car for speed. My Electric Drive tops out at 96 mph, which I've only ever seen going downhill with a tailwind on the freeway. It gets there, but the whole car feels like it's working overtime. It’s perfectly fine for getting up to 70 mph to pass someone, but that’s about it. This car is a champ for my 30-mile daily round trip, not for racing.

From an standpoint, the 96 mph limit on the 2015 Smart is a calculated decision. The short 73.5-inch wheelbase, while great for turning, can compromise high-speed stability. The electronic governor prioritizes safety, preventing dynamics that could unsettle the vehicle. The electric motor's power band is ideal for low-end torque, not sustained high-RPM operation. Pushing beyond this limit would stress the battery and drivetrain unnecessarily, reducing the vehicle's overall longevity and efficiency.

I test-drove one when considering a city car. The salesman was upfront: it'll do 96, but you'll never want to. On the highway, it feels buzzy and light, especially next to big trucks. The acceleration is peppy until about 50 mph, then it really flattens out. It's a trade-off. You get incredible parking ease and low running costs, but you sacrifice that confident, solid feel at higher speeds that you'd get in a compact hatchback.

Think of it like this: a 2015 car is designed for a specific job, and that job isn't setting land speed records. The 96 mph top speed is more than enough for legal driving anywhere in the country. What you're really getting is a vehicle that can slip into any parking spot and costs very little to run. If your life revolves around city commuting, the top speed is a non-issue. If you regularly take long, high-speed road trips, you'd be better served by a different type of vehicle altogether.
