What is the Top Speed of a Smart Car?
Introduction
When people talk about Smart cars, they often think of those tiny vehicles zipping around city streets and squeezing into tight parking spots. But how fast can these compact cars actually go? Many drivers wonder about the top speed of Smart cars and whether they can keep up on highways or are just meant for slow city driving. In this post, we’ll look at the top speeds of different Smart car models, what affects how fast they can go, and how they compare to other cars on the road. Whether you’re thinking about buying a Smart car or just curious about these little vehicles, read on to learn all about their surprising performance capabilities.
Understanding Smart Car Models
The Original Smart ForTwo
The Smart car brand started with the Smart ForTwo, a tiny two-seater that’s become famous for its compact size. The original gas-powered Smart ForTwo (first and second generations) had a small engine that could reach top speeds between 80-90 mph (129-145 km/h). While this isn’t race car territory, it’s fast enough for highway driving in most places.
These early models came with either a 0.7-liter or 0.8-liter three-cylinder engine. Later versions got slightly bigger 1.0-liter engines. None of these were speed demons, but they weren’t designed to be – they were built for city driving and fuel efficiency.
The time it took to go from 0 to 60 mph was pretty slow – often around 15 seconds, which is much slower than most regular cars. But once they got up to speed, they could cruise on highways without problems.
Third Generation Smart ForTwo
The third generation Smart ForTwo, which came out in 2014, got a bit faster. These models could reach top speeds of about 94-96 mph (151-155 km/h). They came with either a 1.0-liter naturally aspirated engine or a 0.9-liter turbocharged engine.
The turbo version was noticeably quicker, going from 0 to 60 mph in around 10 seconds. The non-turbo version still took about 14-15 seconds to reach that speed.
This generation also introduced better transmissions. Earlier Smart cars had a somewhat jerky automated manual transmission that many drivers didn’t like. The newer models offered a much smoother dual-clutch automatic transmission that made driving more pleasant.
Electric Smart Models
Smart also makes electric versions called the Smart EQ ForTwo. These electric models have different performance characteristics than the gas versions. The latest electric Smart cars have top speeds that are electronically limited to about 81 mph (130 km/h).
While this top speed is lower than the gas models, electric Smart cars feel quicker in city driving because electric motors deliver instant torque (pushing power). They can go from 0 to 60 mph in about 11-12 seconds – not fast by today’s standards, but quick enough for urban driving.
The range of electric Smart cars is limited – usually between 70-80 miles on a full charge. This makes them best suited for city commuting rather than long highway trips.
Performance Smart Models
For those wanting more speed, Smart has created some special performance versions over the years. The Smart Brabus models were tuned by the Brabus company to offer more power and higher top speeds.
The Brabus versions of the Smart ForTwo could reach top speeds of around 96-103 mph (155-165 km/h). They also accelerated faster, with 0-60 mph times dropping to about 8-9 seconds in some models.
These performance versions had upgraded suspensions, sporty exhausts, and special wheels to match their increased speed capabilities. However, they were more expensive and used more fuel than regular Smart cars.
Factors Affecting Smart Car Speed
Weight and Aerodynamics
Despite their small size, Smart cars aren’t as lightweight as you might think. The safety cell construction adds weight, with most models weighing between 1,500-2,000 pounds (680-900 kg). This is lighter than regular cars but still substantial for such a small vehicle.
The boxy shape of Smart cars isn’t great for aerodynamics (how air flows around the car). Their tall, short design creates wind resistance that limits top speed. This is one reason why Smart cars don’t go as fast as sportier cars with sleek, low profiles.
Smart has improved the aerodynamics in newer models, which helps both top speed and fuel efficiency. But the basic box-like shape remains a limiting factor for ultimate speed.
Engine Power
The engines in Smart cars are very small compared to most other cars. The largest gas engines offered were just 1.0-liter, producing between 70-90 horsepower depending on the model and whether they had turbochargers.
Electric Smart models typically have motors producing about 80 horsepower. This limited power means Smart cars take longer to reach their top speeds and struggle more on steep hills or when carrying heavy loads.
However, these small engines are a key part of what makes Smart cars fuel-efficient and suitable for city driving. They’re not designed for high-speed performance, but rather for practical urban transportation.
Safety Limiters
Many Smart cars have electronic speed limiters that prevent them from going faster than a certain speed, even if the engine could potentially push them faster. This is done for safety reasons and to protect the engine.
The speed limiter in most Smart cars is set around 90-100 mph (145-161 km/h). This is well above legal speed limits in most places, so it rarely affects everyday driving.
Some owners have found ways to remove these limiters to reach higher speeds, but this isn’t recommended as it can be dangerous and might void the warranty or affect insurance coverage.

Smart Cars on the Highway
Real-World Highway Performance
Smart cars can maintain highway speeds of 65-75 mph (105-120 km/h) without any problem. They can reach these speeds in a reasonable amount of time, though not as quickly as larger, more powerful cars.
Once at highway speed, Smart cars can keep up with traffic flow. However, they might struggle more when climbing steep hills or facing strong headwinds compared to bigger cars with more powerful engines.
Passing other vehicles at highway speeds can be challenging in a Smart car. They don’t have much reserve power for quick acceleration when already moving fast, so planning ahead for passing maneuvers is important.
Safety at Higher Speeds
Despite their small size, Smart cars are designed to be safe at highway speeds. They include a strong safety cell, multiple airbags, and electronic stability control systems to help maintain control.
However, the short wheelbase (distance between front and back wheels) and light weight make Smart cars more affected by crosswinds and turbulence from passing trucks. Drivers need to be more attentive to steering at higher speeds.
The tiny size also means there’s less crumple zone (the area of the car that absorbs impact energy in a crash) compared to larger vehicles. While Smart cars meet safety standards, physics favors larger, heavier vehicles in collisions.
Comfort Considerations
Smart cars aren’t the most comfortable for long highway trips. Their short wheelbase means they bounce more over bumps, and road noise can be louder than in larger cars with more sound insulation.
The small engines need to work harder at highway speeds, which can make the cabin noisier. Electric Smart models are quieter in this respect but have limited range for long highway journeys.
Many drivers report that Smart cars feel less stable and more tiring to drive at highway speeds for long periods compared to larger vehicles.
The Future of Smart Car Speed
Newer Models and Innovations
The Smart brand has been reinvented under new ownership. The newest model, the Smart #1, is a compact electric SUV that’s much more powerful than previous Smart cars. It can reach a top speed of about 112 mph (180 km/h) and go from 0-60 mph in just 6.7 seconds.
This new direction suggests future Smart models will likely be faster and more capable. As battery technology improves, electric Smart cars could offer better performance while maintaining their urban-friendly size.
Some markets are also seeing Smart cars from different manufacturers since the brand has changed hands. These new interpretations of the Smart concept might have different performance characteristics.
Speed vs. Purpose
It’s worth remembering that Smart cars were never designed to be fast. Their main purpose is efficient urban transportation, easy parking, and environmental friendliness. Top speed is not a priority in their design.
As cities become more congested and environmental concerns grow, the focus on speed might become even less important for Smart cars. Future models might continue to offer moderate top speeds while emphasizing other qualities like range, comfort, and tech features.
For those who need both city practicality and highway performance, there might be Smart models that offer a better balance in the future, but they’ll likely remain focused on urban use.
