At Enterprise Rent-A-Car, a full-size car is typically a 4-door sedan that offers more interior passenger room, cargo space, and power compared to standard compact and midsize options. Think of models like the Impala, Toyota Avalon, or Nissan Maxima. These vehicles are designed for comfort on longer trips and can comfortably accommodate five adults with their more generous legroom and trunk capacity, which often exceeds 15 cubic feet. They usually feature a V6 or more powerful 4-cylinder engine, providing a smoother ride for highway driving.
The primary advantage of choosing a full-size car at Enterprise is the significant upgrade in comfort without stepping up to a premium or SUV category. It's an ideal choice for business travelers, small families on vacation, or anyone who values extra space. However, it's important to note that the specific model you receive is subject to availability at your rental location. Enterprise groups similar vehicles by class, not by a specific make and model.
When considering a full-size rental, compare it to other classes. A midsize car (like a Toyota Camry) might be sufficient for four people on a short trip, but the full-size will be noticeably roomier. If you're traveling with significant luggage or more than three people, the full-size sedan is a smart minimum. Be aware that fuel economy will be slightly lower than a compact car.
| Feature | Full-Size Car (Typical Examples) | Midsize Car (Typical Examples) |
|---|---|---|
| Passenger Capacity | 5 adults | 5 adults (less legroom) |
| Typicall Engine | V6 or powerful 4-cylinder | 4-cylinder |
| Trunk Space (cu ft) | 15.5 - 16.5 | 13.5 - 15.5 |
| Fuel Economy (MPG) | 22-30 Combined | 26-35 Combined |
| Best For | Longer trips, business travel, more comfort | Everyday driving, better fuel efficiency |

In my experience, it's the car you get when a midsize feels too cramped. You book a "full-size" and often end up with something like a Chevy Impala. The key difference is the back seat – adults can actually sit back there for a couple of hours without complaining. The trunk is huge, perfect for airport runs with multiple suitcases. Just expect to pay a bit more for gas compared to a smaller car. It's the sweet spot between economy and luxury.

From a practical standpoint, a full-size car at Enterprise means prioritizing passenger comfort over fuel costs. These sedans, such as the Avalon, are defined by their EPA-classified "Large" interior volume index. This translates to real-world benefits: easier entry and exit, more shoulder room, and a ride that absorbs road imperfections better. It's a rational choice for ensuring everyone arrives relaxed, especially when the rental duration is several days or the itinerary involves extensive driving.

I always go for a full-size when I'm on a work trip with a colleague. We did a midsize once and it was a nightmare with our two roller bags and suit bags. The full-size sedan has a deep trunk that swallows all our gear easily. The interior is quiet, which is great for calls, and the ride is just more polished on the highway. For me, the extra $10 or $15 a day is worth it for the professional impression and comfort.

Think of it as an upgrade from the basic family sedan. While a standard midsize car gets the job done, a full-size car at Enterprise adds a layer of comfort and space. You're looking at vehicles designed for executives and long-distance comfort—think plush seating, premium materials, and a powerful, quiet engine. It's not just about fitting five people; it's about fitting them comfortably with room to spare. If your trip is more about the journey than just the destination, this class is worth the splurge.
