The compact car is almost always bigger than the economy car. This classification, primarily defined by the U.S. Environmental Protection Agency (EPA), is based on interior passenger and cargo volume, not just exterior size. An economy car (or "subcompact") prioritizes maximum fuel efficiency and affordability, resulting in a smaller overall package. A compact car offers a noticeable step up in space for both people and their belongings, while still remaining relatively fuel-efficient.
The key difference lies in interior dimensions. While exterior lengths can sometimes overlap, a compact car's cabin is designed to provide more legroom, shoulder room, and headroom for all occupants, especially those in the rear seats. The trunk space is also significantly larger. For example, an economy car might have just enough trunk space for a few grocery bags, whereas a compact sedan's trunk can easily accommodate luggage for a weekend trip.
| Vehicle Class | Typical Interior Volume (Passenger + Cargo) | Example Models | Typical Rear Legroom | Typical Cargo Volume (Trunk) |
|---|
| Economy / Subcompact | 85-99 cubic feet | Chevrolet Spark, Mitsubishi Mirage | 31-33 inches | 11-15 cubic feet |
| Compact | 100-109 cubic feet | Honda Civic, Toyota Corolla, Hyundai Elantra | 35-37 inches | 14-17 cubic feet |
| Midsize | 110-119 cubic feet | Honda Accord, Toyota Camry | 38-40 inches | 15-17 cubic feet |
Choosing between them depends on your needs. If you're primarily a solo commuter who prioritizes parking ease and the lowest possible running costs, an economy car is sufficient. However, for small families, frequent highway drivers, or anyone who regularly carries more than one passenger, the compact car's extra space is worth the modest increase in price and slight decrease in fuel economy. The comfort and practicality it offers make it the bigger and generally more versatile choice for the average American driver.
