The Smart Fortwo fuel tank capacity is 33 litres or 7.25 gallons max
The Smart Fortwo is a compact car designed for urban commuters, especially those living in large metropolitan areas. It was a joint venture between the Swiss company Swatch and Mercedes, and was sold from 2008 to 2019. The fuel tank capacity of the Smart Fortwo is 33 litres or 7.25 gallons max.
This capacity is significantly smaller than the average sedan; for example, the Toyota Camry has a fuel capacity of 14.4 gallons. However, the Smart Fortwo's fuel efficiency means that it won't need to be refuelled frequently, even if you're driving across town or to a neighbouring city.
There are mixed reports about the fuel tank capacity of the Smart Fortwo. Some sources claim that the tank can hold 8.7 gallons, plus an additional reserve of 1.3 gallons, bringing the total capacity to 10 gallons. Other sources, including the car manual, claim that the reserve is 1.3 gallons, while dealerships and Smart engineers state that it is actually 2.9 gallons.
It's important to note that filling up the fuel tank of any car to the neck of the fuel pipe is not recommended, as it may explode or cause a spill if the cutoff on the fuel nozzle does not work properly.

The fuel tank also has a reserve of 1.3 gallons
The Smart Fortwo is a small car with a small fuel tank to match. The fuel tank holds 7.25 gallons (33 litres) at maximum capacity. However, the fuel tank also has a reserve of 1.3 gallons. This means that, even when the tank appears to be empty, it still contains 1.3 gallons of fuel. This is useful if you need to drive somewhere quickly and don't have time to fill up with gas.
The reserve is approximately 33% of the tank's total capacity. This means that, if you fill up your tank when the reserve drops to zero, you will only be filling the tank to about two-thirds of its capacity. This can be a useful strategy to avoid overfilling the tank and spilling fuel.
It's important to note that the fuel tank capacity and reserve may vary slightly depending on the model year and type of your Smart Fortwo. For example, some sources suggest that the fuel tank capacity is 8.7 gallons, while others claim it can hold up to 16 gallons. Additionally, there are reports of discrepancies between the Owner's Manual, which states a reserve of 1.3 gallons, and statements from dealerships and engineers, who claim the reserve is actually 2.9 gallons.
To ensure you have accurate information about your specific Smart Fortwo model, it's recommended to refer to the Owner's Manual or consult with an authorized dealer or mechanic.

The tank can be modified to hold its full capacity of 16 gallons
The Smart Fortwo is a small car designed for urban commuters, offering solid mileage and a compact form factor. The fuel tank capacity of the Smart Fortwo has been a topic of discussion among owners, with varying figures mentioned in the owner's manual, online forums, and dealerships.
According to the owner's manual and smart USA's website, the Smart Fortwo's fuel tank has a capacity of approximately 2.9 gallons, including a reserve of 1.3 gallons. However, some owners have disputed this information, claiming that the actual capacity is higher. One owner claimed that the tank can be modified to hold its full capacity of 16 gallons, which is a significant increase from the advertised capacity.
To achieve this modification, the owner mentioned relocating one of the float valves to the top outside of the tank. This change allows the tank to hold a larger amount of fuel, increasing the vehicle's range and reducing the frequency of refuelling. It is important to note that modifications like this should be approached with caution and at the owner's risk, as they may void warranties or impact the vehicle's performance in unexpected ways.
The discrepancy in fuel tank capacity figures may be due to differences in model variants or regional specifications. Some owners have reported that their Smart Fortwo vehicles have a maximum fuel tank capacity of 7.25 gallons or 33 litres, which is still higher than the figure mentioned in the owner's manual. It is always recommended to refer to the official sources and authorized dealerships for accurate and up-to-date information regarding fuel tank capacity and any potential modifications.
While the Smart Fortwo may have a smaller fuel tank capacity compared to larger sedans, it is designed for efficiency and manoeuvrability in urban environments. The ability to modify the fuel tank to hold its full capacity of 16 gallons can further enhance the vehicle's range and practicality for those seeking to maximize their fuel efficiency and reduce refuelling stops.

The Smart Fortwo is manufactured by a joint venture between Swatch and Mercedes
The Smart Fortwo is a two-seater city car manufactured and marketed by the Smart division of the Mercedes-Benz Group. The car was conceptualized by Daimler-Benz in the 1970s and 1980s as a compact city car to address growing traffic congestion and pollution. The design was originally developed in collaboration with Volkswagen, but the project was terminated by Volkswagen's new CEO, Ferdinand Piëch, in 1993.
After being rejected by several other car companies, the project eventually found a home with Daimler-Benz AG, the maker of Mercedes-Benz cars. The Smart marque was founded in 1994 by Micro Compact Car AG (MCC), a joint venture between SMH (makers of the Swatch brand of watches) and Daimler-Benz. The name "Smart" is derived from the cooperation between the Swiss company Swatch and Mercedes-Benz: "Swatch Mercedes ART".
The first model of the Smart Fortwo, then known as the "City Coupé", was released in 1998. It was manufactured at Smartville, a dedicated Daimler assembly plant in Hambach, France, and offered in Coupé (hatchback) and Cabrio (convertible) body styles. The Fortwo has since gone through two additional generations, each using a rear-engine, rear-wheel-drive layout and a one-box design. The second-generation Fortwo remained the lightest production car on sale in Europe, and the third generation was introduced in 2014.
In 2019, Smart underwent a significant transition, becoming the first automotive company to fully shift from internal-combustion engines to an all-electric product line-up. This move coincided with the establishment of a joint venture between Mercedes-Benz AG and Geely Automobile Co., Ltd., resulting in the reinvention of the Smart brand and a new business model focused on electric mobility.

The car was aimed at accommodating those who lived in large metropolitan areas
The Smart car was designed to be compact and fuel-efficient, with a particular focus on accommodating drivers in large metropolitan areas. Its small size made it ideal for navigating through busy city streets and tight parking spots. The Smart Fortwo, for example, has a fuel tank capacity of 8.7 gallons, with an additional reserve of 1.3 gallons, allowing drivers to go further on a single tank.
In comparison to other vehicles, the Smart car's fuel tank capacity may seem smaller. For instance, the Toyota Camry has a fuel tank capacity of 14.4 gallons. However, the Smart car's efficiency allows it to achieve impressive mileage on a single tank. The 2017 Fortwo coupe, for example, can achieve 33 miles per gallon in city driving and 39 miles per gallon on the highway.
The compact size of the Smart car, coupled with its fuel efficiency, made it a convenient choice for urban commuters. Its manoeuvrability and ease of parking were advantageous for those living in densely populated metropolitan areas. The car's fuel tank capacity, while smaller than some other vehicles, was designed to provide sufficient range for city driving, with the ability to venture beyond city limits without frequent refuelling.
While Smart cars may not have been as prevalent on American roads, they offered a unique combination of a compact form factor and solid mileage. The fuel tank capacity of the Smart car, as discussed, varied depending on the model, with some owners reporting variations in the actual capacity compared to the advertised amount. Despite this, the Smart car's overall design and efficiency made it a practical choice for city dwellers, offering convenience and flexibility for their daily commutes and errands.
