Some owners of the Smart Fortwo have reported varying MPG figures. Some have achieved around 27-28 MPG, while others have reported figures as high as 42-47 MPG with mixed highway, county, and city driving. It's important to note that driving habits and conditions can significantly impact fuel efficiency, and individual results may vary.

To maximize fuel efficiency in the Smart Fortwo, it is recommended to use the manufacturer's recommended fuel, which is typically a higher-octane fuel. Additionally, maintaining the vehicle, such as using high-performance air filters and changing spark plugs regularly, can help ensure optimal fuel efficiency.

The Smart Fortwo is an excellent choice for those seeking a fuel-efficient city car for short commutes and errands. Its compact size and manoeuvrability make it ideal for navigating through city traffic and parking in tight spaces.

Smart Car's wind resistance design

Smart cars were designed to be small, fuel-efficient, environmentally responsible, and easy to park. The flagship "ForTwo" model, named for its human-carrying capacity, is about half the size of a traditional car. The U.S. Environmental Protection Agency (EPA) rates the car's fuel efficiency at 32 miles per gallon (mpg) for city driving and 39 mpg on the highway for the 2016 model year. The Smart car ForTwo has a fuel tank capacity of 8.7 gallons and gets around 40 miles per gallon (MPG), allowing you to typically drive about 350 miles before refuelling.

The wind resistance of a Smart car is designed for maximum MPG. Manufacturers use wind tunnel testing to optimise the aerodynamics of their vehicles, allowing air to flow easily with the least possible resistance. Computational fluid dynamics (CFD) tools enable engineers to test their designs under a wide range of operating conditions, reducing design costs and time.

Modern vehicle design techniques that help reduce air resistance include recessing the windscreen wipers and door handles, streamlining outside mirrors, and eliminating raised gutters around the roof. These features enhance the vehicle's performance and improve fuel efficiency.

Smart has recently released details of its first-ever sports utility coupe, the Smart #3, which features a streamlined coupe style with excellent aerodynamics performance and a drag coefficient of just 0.27. This model combines world-class aerodynamics with a dynamic design, offering advanced aerodynamics and improved performance.

Additionally, convertible wind deflectors can be attached behind the driver's seat of Smart cars to prevent turbulence when driving with the top down. These wind deflectors improve comfort by reducing air draught and protecting drivers and passengers from drafts, even at high speeds.
