About smart specifications on AutoSpecData
This hub indexes every smart model line we hold verified data for — 1 nameplate covering 18 distinct trim and powertrain combinations across model years 2015 to 2019. That works out to roughly 18 variants per model line, which is why picking the exact year and engine matters when you compare fuel economy: two smart vehicles wearing the same badge in the same year can differ by several MPG depending on drivetrain and transmission.
The deepest smart coverage sits with the fortwo (18 variants, 2015–2019). 1 smart model is still current as of 2019.
Every smart model page below breaks its data into five focused views: fuel economy (EPA city, highway, and combined MPG plus estimated annual fuel cost), engine specifications (displacement, cylinder count, fuel type, and forced induction where applicable), transmission, drivetrain, and vehicle class. Where a smart model is rated for towing or has published bed and cargo dimensions, those figures appear on the model page too. Figures come from the EPA and Department of Energy fueleconomy.gov datasets and are cross-checked against NHTSA vPIC records; blank fields mean the source data does not publish that value for that trim, not that the value is zero.
If you are cross-shopping, start with the model you already have in mind, note the combined MPG for the specific year and drivetrain, then use the comparison tool to put it side by side against a rival. Annual fuel cost is usually the number that separates two otherwise similar smart trims over a five-year ownership window.
smart specs: common questions
How many smart models are covered here?
1 smart model line are covered, spanning 18 individual trim and powertrain combinations from model years 2015 through 2019. Each model page breaks those trims out year by year with EPA city, highway, and combined MPG, engine displacement, cylinder count, transmission, and drivetrain.
Which smart model has the most trim data?
The smart fortwo has the deepest coverage with 18 recorded variants between 2015 and 2019. Model lines with more variants usually offered several engines, drivetrains, or transmission choices in the same year, so comparing trims within a single year matters more than comparing across years.
What model years of smart vehicles are included?
Coverage runs from 2015 to 2019. The longest-running entry is the smart fortwo (from 2015), and the most recently updated is the smart fortwo (through 2019). Older years are included because used-car shoppers and owners looking up maintenance intervals need them as much as new-car buyers do.
Where does the smart data come from?
Fuel economy, engine, transmission, drivetrain, and vehicle-class fields come from the US EPA and Department of Energy fueleconomy.gov datasets, with vehicle identification cross-checked against the NHTSA vPIC database. Nothing is estimated by us: if a figure is missing for a given smart trim, the field is left blank rather than filled with a guess.
Are these smart MPG figures real-world numbers?
They are EPA laboratory test ratings, which is the same standard used on the window sticker. Real-world results for a smart typically land within about 10-15% of the combined rating, and drop further in cold weather, in stop-and-go traffic, at sustained highway speeds above 70 mph, or when towing.
