A subcompact car is the smallest standard passenger car category, defined by the Environmental Protection Agency as any car with a combined interior volume (passenger space plus trunk space) of 85 to 99 cubic feet. These are short, narrow vehicles built for fuel efficiency and easy parking, typically the least expensive new cars on the market. The segment has been shrinking rapidly in the U.S. as buyers shift toward crossovers and SUVs, but a handful of subcompacts remain available.
How the EPA Defines Car Sizes
The EPA classifies passenger cars into size categories based on interior volume index, which combines the passenger compartment and cargo area into a single cubic-foot measurement. Subcompact cars fall between 85 and 99 cubic feet. Anything below 85 cubic feet is classified as a minicompact, and anything from 100 to 109 cubic feet moves into compact territory. This system exists primarily so the EPA can compare fuel economy ratings among similarly sized vehicles, but it’s become the standard way the industry talks about car size classes.
In practical terms, a subcompact typically seats four adults, though rear passengers will notice tighter legroom and shoulder room compared to a compact sedan. Trunk space usually ranges from about 12 to 15 cubic feet with the rear seats up, enough for a couple of suitcases but not much more. Hatchback versions offer more flexibility since folding the rear seats opens up significantly more cargo room.
What Subcompacts Cost
Subcompacts have traditionally been the cheapest new cars you can buy. The 2025 Nissan Versa starts at $18,330, making it the most affordable new car in America. Other subcompacts like the Mini Cooper, Mazda MX-5 Miata, and Audi A3 sit higher on the price spectrum, but those models compete on driving experience or brand appeal rather than pure affordability. The core promise of a subcompact has always been low cost of entry paired with strong fuel economy, often reaching 35 to 40 miles per gallon on the highway for gas-powered models.
Models Still on the Market
The list of available subcompacts is short and getting shorter. Current models include the 2025 Nissan Versa, 2025 Mini Cooper, 2025 Subaru BRZ and its twin the Toyota GR86, the Mazda MX-5 Miata, the Fiat 500e (an electric model), and the 2025 Audi A3. Some of these, like the BRZ and Miata, are sports cars that happen to fall into the subcompact class because of their small interiors rather than because they were designed as budget transportation.
The Mitsubishi Mirage, long one of the cheapest cars on the road, will be discontinued after 2025. Rumors suggest the Nissan Versa may also be in its final year, which would eliminate the last true subcompact sedan from a major manufacturer in the U.S.
Why Subcompacts Are Disappearing
A decade ago, buyers could choose from the Chevy Sonic, Chevy Spark, Honda Fit, Ford Fiesta, Toyota Yaris, Hyundai Accent, and Kia Rio. Every one of those has been canceled. The reasons are consistent across manufacturers: thin profit margins, declining sales volume, and the rising cost of meeting U.S. safety and emissions regulations on a vehicle that sells for under $20,000.
GM killed the Chevy Sonic in 2020 and the even smaller Spark in 2022, exiting gas-powered subcompacts entirely. Honda ended the Fit in 2020 and replaced it with the HR-V, a small crossover SUV. Toyota pulled the Yaris from North America the same year, concluding that the cost of keeping the car compliant with tightening regulations wasn’t justified by its sales numbers. The Kia Rio, Hyundai Accent, and Ford Fiesta sedans all followed the same path.
The pattern is clear: automakers make more money on crossovers and SUVs, and that’s where buyers are spending. Small crossovers like the Honda HR-V, Hyundai Venue, and Kia Soul now occupy the affordable, fuel-efficient space that subcompacts once owned, but with higher ride heights and more cargo room.
Safety Considerations
Physics works against smaller cars in collisions. When a lighter vehicle hits a heavier one head-on, the occupants of the lighter vehicle absorb more force. This doesn’t mean subcompacts are unsafe in absolute terms. Modern subcompacts carry the same core safety technology as larger cars: multiple airbags, electronic stability control, and increasingly standard automatic emergency braking. Many earn four- or five-star ratings from the National Highway Traffic Safety Administration, which evaluates frontal crashes, side impacts, and rollover resistance.
The real risk isn’t how a subcompact performs crashing into a barrier in a lab. It’s how it performs sharing the road with vehicles that outweigh it by 1,000 to 2,000 pounds. As the average vehicle on American roads has gotten larger and heavier, the size mismatch has become a growing concern for anyone driving the smallest cars on the road.
Who a Subcompact Makes Sense For
Subcompacts work best for city driving. Their small footprint makes parallel parking and navigating tight streets easier than in almost any other vehicle. They’re cheap to insure, cheap to fuel, and cheap to buy. If your daily driving is a short urban commute and you rarely carry more than one passenger, a subcompact handles that job efficiently.
They’re less ideal for highway cruising, where road and wind noise are more noticeable, or for families who need rear-seat space and cargo room. Long road trips in a subcompact can feel fatiguing compared to a larger car simply because there’s less insulation between you and the road. If you’re cross-shopping a subcompact against a small crossover or compact sedan, the price difference has narrowed enough that the subcompact’s main advantage is now its smaller physical size rather than a dramatic savings on the sticker price.
