The search for the perfect car often starts with pragmatic requirements, and one of the most popular requests is a spacious luggage compartment with easy access. The phrase "cars with the rear trunk open" colloquially usually describes hatchback, liftback or station wagon body types, where the rear door rises with the glass to provide a wide opening. This radically distinguishes them from classic sedans, where access to luggage is limited to a narrow rectangular opening under the shelf.
The choice of such a body is dictated not only by the desire to transport large loads, but also by the general ergonomics of urban use. Owners note that the ability to fold the rear row of seats and get a flat floor from the fifth door to the front bumper is a decisive factor when purchasing. Modern manufacturers are increasingly abandoning the classic three-box design in favor of more practical solutions, offering customers universal vehicles.
In this article we will analyze in detail the technical features of various types of body with a rear door, compare their capacity and discuss the nuances of operation. You'll find out why hatchback may be more convenient than a sedan, and in what cases is it worth overpaying for liftback. We will also touch on safety and aerodynamics issues, which often cause controversy among car enthusiasts.
Main types of bodies with a rear door
When people talk about a car with an open rear trunk, they most often mean a hatchback. This is a body that does not have a protruding trunk, and the rear wall is represented by a door that opens upward. The roof line in such cars usually ends abruptly, which forms a characteristic silhouette. Hatchbacks are divided into three-door and five-door modifications, where the number of doors also takes into account the trunk lid itself.
Another popular option is a liftback. Visually, it may resemble a sedan thanks to the sloping roofline and slight overhang, but structurally it is the same hatchback. back door liftback opens with the glass, providing a huge opening. This solution allows you to maintain the graceful contours of the body without sacrificing the practicality of loading.
The third type is a station wagon. Here the roof extends all the way to the rear bumper, creating maximum interior volume. If you need cargo-passenger car, then a station wagon would be the best choice. Its opening height is often lower than that of a hatchback, but the overall length of the luggage compartment is significantly longer.
Advantages of a wide loading opening
The main advantage of cars with a rear door is the dimensions of the opening. Unlike a sedan, where you have to push cargo through a narrow opening, here you have access to the entire interior volume. This is critically important when transporting household appliances, building materials or large furniture.
The second important aspect is the transformation of the interior. Folding down the rear seatbacks creates a flat surface. In a sedan, even if there is a hatch in the back of the sofa, it is extremely difficult to load a long object (for example, skis or boards) due to a break in the body. Machines with hinged door allow you to form a load up to two meters or more in length.
It is also worth mentioning the ease of loading in tight parking conditions. You don't have to swing the side doors wide open to get your package out of the trunk. It is enough to open the back cover, which is especially important if the car is parked close to a pole or another car.
- 🚗 Possibility of loading items exceeding the dimensions of a standard sedan trunk.
- 📦 Convenience of cargo formation due to the absence of a partition between the cabin and the luggage compartment.
- 🅿️ Saves space when parking due to no need to open the side doors to access things.
When purchasing a car, pay attention to the height of the trunk sill. On some hatchbacks it may be high, making it difficult to load heavy boxes without tilting.
Capacity Comparison: Hatchback vs Estate
Although both body styles offer a tailgate, their capacity differs significantly. Station wagons gain in volume when loading “under the roof”, while maintaining legroom for second-row passengers. Hatchbacks, in turn, often offer more space in the vertical plane, but their compartment length is limited.
An important parameter is the width of the opening between the arches. For many models this indicator is standardized, but for cross hatchbacks it may be narrower due to the plastic lining. When choosing a car for commercial purposes or frequent trips to the country, it is necessary to measure the diagonal of the opening, and not just the declared displacement.
Below is a comparison table of typical characteristics for C-Class cars so that you can clearly see the difference.
| Body type | Trunk volume (min) | Volume with seats folded | Opening height |
|---|---|---|---|
| Hatchback | 350-400 l | 1200-1300 l | Average |
| Liftback | 450-500 l | 1400-1500 l | High |
| Station wagon | 500-600 l | 1600-1800 l | Medium/High |
| Crossover | 400-450 l | 1300-1400 l | High |
The liftback is often the “golden mean”, offering the volume of a station wagon in the dimensions of a hatchback, which is ideal for the city.
Nuances of aerodynamics and fuel consumption
There is a common misconception that cars with a vertical rear wall have worse aerodynamics. Really classic hatchback creates a zone of turbulence behind it, which can increase air resistance at high speeds. However, modern engineers have learned to compensate for this with spoilers and a special roof topography.
The fuel consumption of such cars can be 0.5–1 liter higher than that of streamlined sedans when driving on the highway at speeds above 110 km/h. In the urban cycle, the difference is almost imperceptible, since the main role is played by the mass of the car and engine performance, and not by the shape of the body.
⚠️ Attention: When installing a roof rack on a hatchback or station wagon, the aerodynamic drag increases significantly more than that of a sedan. This can lead to an increase in fuel consumption of up to 20-30% on the highway.
To minimize noise and consumption, it is recommended to use closed boxes instead of open frames. It is also worth keeping an eye on the cleanliness of the rear window and visor, as eddy currents in this area contribute to the rapid accumulation of dirt.
Safety and security of cargo
The absence of a partition between the passenger compartment and the trunk imposes certain safety requirements. When braking suddenly, loose objects in the luggage compartment can become dangerous projectiles. Therefore the presence standard grid or the possibility of installing a rigid partition is an important selection criterion.
The issue of safety of things is also acute. In a hatchback, the entire interior is visible through the rear window, which can attract the attention of intruders. The solution to the problem is tinting, curtains or using opaque cargo covers. In a sedan, the trunk is hidden from view, which is psychologically more comfortable for the owner.
- 🔒 Be sure to use a trunk curtain or net to secure the cargo when moving.
- 👁️ Tinting the rear window and side windows of the fifth door reduces the risk of theft out of curiosity.
- 🛑 Do not leave valuables in sight, even if the parking seems safe.
What to do if there is no standard curtain?
You can use an elastic mesh with hooks that is stretched between the handles above the doors. This is a budget analogue that prevents things from flying around the cabin when braking.
Operation in winter and in bad weather conditions
An open trunk has its own operating characteristics in winter. When opening the door, snow and ice from the roof can spill directly onto the head of the person opening it or into the trunk. Construction visor above the door plays a decisive role here: the wider it is, the less moisture will get into the cabin.
Another problem is rear window fogging. Due to the peculiarity of air flows behind the vertical wall, snow and dirt are actively sucked into the wiper area. good washer and a high-quality wiper blade for a hatchback are consumables that should always be in stock.
In severe frosts, the rubber door seals can freeze. Opening the door suddenly with force can damage the mechanism or the seal itself. It is recommended to treat rubber profiles with silicone grease before the onset of cold weather.
☑️ Preparation for winter for the hatchback owner
Frequently asked questions (FAQ)
Is it true that a hatchback is colder in winter than a sedan?
No, it's a myth. The heating system and thermal insulation of the interior of modern cars do not depend on the type of body. However, due to the larger volume of air in the cabin (including the luggage compartment), warming up may take a couple of minutes longer, but the resulting temperature will be the same.
Is it possible to carry rear passengers in a hatchback if the trunk is full?
Technically it is possible, but it is not safe. The load must be securely secured and must not protrude beyond the seat backrests. If items are placed above the head restraints, they can injure passengers during sudden braking.
Which body is better for a taxi: hatchback or sedan?
For economy class, sedans are often chosen because of their popularity and liquidity. However, for transportation with a large amount of luggage (airports, train stations), a hatchback or station wagon will be preferable due to the ability to load large bags without problems.
Does the rear window of open-top cars get more dirty?
Yes, aerodynamic vortices behind the vertical wall of the body pull in road dirt and snow. This is a design feature that requires more frequent use of windshield washer compared to sedans.
