The compact size of gasoline-powered smart cars contributes to their impressive fuel economy, as they have restricted room for gasoline. The choice between an electric or fuel-run smart car depends on various factors, including environmental considerations, mileage expectations, and personal preferences.
When it comes to fuel type, some discussions revolve around the use of regular versus premium gasoline in smart cars. Some users have reported similar performance and mileage with both types of fuel, while others suggest that premium fuel may be recommended by manufacturers to prevent potential engine damage. The decision to use regular or premium fuel may depend on factors such as cost, availability, and manufacturer recommendations.
In conclusion, the choice between an electric or fuel-run smart car depends on individual preferences and priorities. Electric smart cars offer environmental benefits and are considered "green," while gasoline-powered smart cars excel in fuel efficiency and provide impressive mileage. The fuel type, whether regular or premium gasoline, is also a consideration for smart car owners, with some users reporting varying experiences and opinions.

Premium vs. regular gas
The fuel you use in your car can make a difference in performance and mileage. Premium gasoline has a higher octane rating, which means it has a greater resistance to "knocking" or the early combustion of the fuel-air mixture that causes cylinder pressure to spike. This can be beneficial for high-performance engines with forced induction (turbo/supercharger) as they operate at higher cylinder pressures.
Some car manufacturers, like BMW, explicitly warn about engine damage from using regular unleaded gasoline and recommend using premium gasoline with a minimum of 91-octane fuel. However, for everyday driving in a standard sedan or SUV, using premium gasoline may not provide any noticeable benefits over regular gasoline, and you may be wasting your money.
There are mixed experiences among Smart Car owners. Some have reported no difference in performance or mileage when using regular gasoline, while others have noticed a slight decrease in MPGs when using regular gasoline. One user reported getting 10 mpg less with regular gasoline than with premium.
It is important to consult your car's manufacturer recommendations and consider the type of engine your car has when deciding between premium and regular gasoline. If your manufacturer recommends premium fuel, it is best to follow their suggestion to avoid potential engine damage.
Additionally, retailers may add different additives to their fuels, which can affect performance. However, there is limited data to support the effectiveness of these additives.

Fuel efficiency tips
Smart cars are known for their fuel efficiency, which is one of their main selling points. The fuel efficiency of a car is measured in miles per gallon (MPG), and smart cars typically have an MPG of around 40. However, this can vary depending on various factors such as the model, transmission type, driving habits, road conditions, weather, tire pressure, and vehicle maintenance.
- Check your owner's manual for the ideal tire pressure and ensure that your tires are always properly inflated.
- Keep your tires aligned and replace them when they are worn out.
- Change your air filter when it gets dirty.
- Avoid overloading your trunk with too much stuff.
- Change your oil at regular intervals.
- Avoid aggressive acceleration and braking.
- Maintain a steady speed whenever possible.
- Minimize idling time.
- Consider using the paddle shifters (if your model has them) to shift up and down early, which can help with engine braking and improve fuel efficiency.
- Take advantage of start-stop systems (if available on your model) to shut off the engine when the vehicle is stationary, conserving fuel.
- Look into regenerative braking systems (if applicable to your model) that capture and store energy during braking.

Gas mileage in city vs. highway
Smart cars are known for their excellent fuel efficiency, with an average gas mileage of 40 miles per gallon (mpg). However, the gas mileage varies depending on whether you are driving in the city or on the highway. Several factors affect gas mileage in city and highway driving, and understanding these factors can help improve fuel efficiency.
City driving typically results in lower gas mileage compared to highway driving due to frequent stops, accelerations, and decelerations. The engine works harder in city driving, as it has to constantly adjust to changing speeds and traffic conditions. Additionally, city driving often involves slower speeds and lower gear usage, which can impact fuel efficiency. To improve gas mileage in the city, it is recommended to drive slowly and defensively, avoiding abrupt stops and starts.
On the other hand, highway driving generally provides better gas mileage as it involves maintaining a consistent speed. Driving at optimal speeds designed for your vehicle can help improve fuel efficiency. However, driving at higher speeds than recommended can lead to increased fuel consumption.
The type of smart car model also influences gas mileage. For example, the 2017 Smart EQ Fortwo has a city/highway/combined mpg of 33/38/35, while the 5-speed manual version has slightly lower efficiency at 31/38/34 mpg. Electric models, such as the Fortwo Electric Drive, offer even higher mpg, with ratings of 124/94/108 MPGe for city/highway/combined.
It is worth noting that factors such as driving habits, terrain, and proper maintenance can also impact gas mileage. Driving habits such as rapid acceleration, hard braking, and speeding can reduce fuel efficiency. Additionally, driving in hilly areas or using lower gears excessively can impact gas mileage. Regular maintenance, such as cleaning the fuel injector and replacing spark plugs, can help optimize fuel efficiency and improve overall vehicle performance.
