The question is what is it called? car without top, often arises among those who are thinking about buying a car for the first time for the warm season or are simply interested in automobile classification. In fact, there is no general name for all open bodies, as engineers and designers have developed many variations of removable or retractable roofs. From classic convertibles from soft awning to technological roadsters with a hard folding roof - each type has its own unique design features and history.
Understanding the difference between these terms is important not only for erudition, but also for the correct choice of vehicle, since aerodynamics, interior noise levels and safety are highly dependent on the body type. Some models allow you to remove the entire roof, leaving only the windshield, while others transform in seconds with the touch of a button. In this article we will analyze in detail the main types of open bodies, their technical nuances and help you decide which option is right for you.
It's worth noting that in the modern auto industry, the boundaries between classes are often blurred, and manufacturers use marketing names that can be confusing. However, the basic principles of classification have remained unchanged for many decades. We'll look at the key differences so you can navigate the world with confidence open cars.
Convertible: an open-sky classic
The most common answer to the question “name of a car without a top” is convertible. Historically, the term comes from a French word meaning “to jump” or “gallop,” which was associated with light carriages. In the modern sense, a convertible is a car with a soft folding roof made of fabric or vinyl, which is hidden in a special compartment behind the rear seats. The main feature of the classic convertible is the presence of full side windows in the doors, which also lower or retract.
The design of such cars requires serious strengthening body, since the absence of a hard roof reduces the overall torsional rigidity of the frame. Engineers have to implement additional reinforcements in the sills and underbody to ensure that the car maintains controllability and safety in a collision. This is why convertibles are often heavier than their closed counterparts, despite the lack of a roof. The soft top provides excellent sound insulation when up, but is inferior to hard tops in protecting against hail or falling branches.
Modern convertibles are equipped with complex hydraulic or electrical mechanisms that allow the roof to be opened on the move at speeds of up to 50 km/h. This makes the process of enjoying the sun as convenient as possible. However, owners of such machines should remember the need to regularly care for the fabric, treat it with water-repellent compounds and check the condition of the folding mechanisms.
It is important to distinguish between a convertible and a phaeton: the latter often has no side glass in the doors or is removable, which makes it more utilitarian and less comfortable in bad weather. Convertible It is positioned as a car for comfortable driving at any time of the year, providing a feeling of open space without compromising on the level of comfort.
Roadster: sport and minimalism
If a convertible is about comfort, then roadster - it's about emotions and sports. Initially, roadsters were two-seater cars with an open top and a minimum amount of equipment, designed for fast driving. Today, a roadster is most often understood as a two-seater sports car that can have either a soft or hard folding top. The key difference from the convertible is the absence of a rear row of seats or the presence of a very cramped space suitable only for luggage.
Many enthusiasts believe that a real roadster should be exclusively rear-wheel drive and have ideal weight distribution. Notable examples are Mazda MX-5, Porsche Boxster or BMW Z4. These cars are created with driver's driving in mind, so they are suspension generally firmer and steering sharper than business class convertibles. The absence of rear doors and a full second row of seats allows designers to make the front axle as close as possible to the center of the car, improving maneuverability.
⚠️ Attention: When purchasing a roadster with a soft top, be sure to check the condition of the drain hatches. In two-seat sports cars, the water drainage system is often compact and prone to clogging with leaves, which can lead to leaks into the cabin.
There is also the concept of "spider", which is often used interchangeably with the roadster, especially in the Italian automotive tradition (eg Ferrari Spider). Technically, the difference is minimal, but spiders are often called more powerful and expensive versions of open sports cars. Roadster owners often find luggage space limited, especially with the top folded down, so weekend trips may require a specially shaped soft bag.
When choosing a roadster, pay attention to the presence of a wind shield (deflector) as standard. It significantly reduces turbulence in the cabin at high speeds, making conversations possible even without the top up.
Targa and other hybrid forms
Not all cars without a top are completely deprived of it. There is a unique body type called targa. This is a hybrid of a coupe and a convertible, where the central part of the roof is removable, but a powerful roll bar (or crossbar between the pillars) remains above the passengers' heads. This design was proposed by the company Porsche in the 1960s as a compromise between the desire to have an open car and the fears of American regulators for the safety of passengers in a rollover.
Unlike a convertible, a Targa usually has a rear window that does not fold down, and the roof can be removed manually and stowed in the trunk or attached to special mounts at the rear. This gives the car a unique appearance and a characteristic exhaust sound that resonates in a half-empty cabin. Modern implementations such as Porsche 911 Targa, use a complex system where the rear part of the roof and glass are retracted electrically, leaving a characteristic arc.
Another interesting option - hardtop convertible (Coupe-Cabriolet). These are cars that have a hard metal roof consisting of several sections that fold into the trunk, turning the coupe into a convertible. Examples: Peugeot 206 CC, Mercedes-Benz SLK (previous generations). The advantages are obvious: excellent sound insulation in winter and a feeling of open sky in summer. However, such mechanisms are complex, heavy and “eat up” a significant part of the luggage compartment.
What is a Landau convertible?
Landaulet is a rare type of body, where the roof over the rear row of seats is soft and foldable, and the front part of the body is rigid, like a sedan. Historically used in executive cars for VIPs so they could wave to the crowd while remaining in comfort. Today it is extremely rare, mainly in the form of exclusive limousines.
There are also more exotic options, such as brogues (Brougham) - a body with a hard roof over the front seats and a convertible top over the rear, which is almost obsolete today. It is also worth mentioning pickup trucks with a convertible top over the body, but they are classified as commercial vehicles. The choice between a targa, hardtop and classic convertible often depends on priorities: whether body rigidity or speed of transformation is important to you.
Comparison table of open body types
To systematize the information and finally understand what it is called car without top in your case, we suggest turning to a comparative analysis. The differences lie not only in the name, but also in the target audience, design and performance characteristics.
| Body type | Upper material | Number of seats | Key Feature |
|---|---|---|---|
| Convertible | Soft fabric/Vinyl | 2+2 or 4 | Full side windows, comfort |
| Roadster | Fabric or hard folding | 2 | Sports orientation, no rear seats |
| Targa | Removable panel / Glass | 2 or 2+2 | Presence of a roll bar, non-removable rear window |
| Hardtop convertible | Metal (complex shape) | 2+2 | Converting a coupe into a convertible, heavy gear |
| Phaeton | Fabric | 4 or more | Removable side windows, historical type |
As you can see from the table, the choice is great. If practicality and the ability to carry passengers in the back are important to you, but you want fresh air, convertible will be the best choice. If you drive alone or with a passenger and appreciate the thrill of the road, then roadster created especially for you. The Targa, on the other hand, is suitable for those who are afraid of losing body rigidity or want a car that looks like a coupe, but allows you to open up the sky.
The main criterion for choosing between a roadster and a convertible is the presence of a rear row of seats and the degree of sporty tuning of the car.
Technical features and service
Owning a car without a top imposes certain obligations on the owner. Roof folding mechanisms are complex components that require attention. First of all, this concerns hydraulics or electric motors that drive roof sections. Over time, the fluid may lose its properties, and air pockets may appear in the system, which will lead to slow or uneven operation of the mechanism.
Fabric uppers require regular cleaning with special shampoos and treatment with impregnations. Cheap products can destroy the protective layer, and the fabric will begin to leak water or fade in the sun. Hard folding roofs, in turn, have many hinges and seals. The rubber bands dry out over time, which leads to drafts and whistling at high speeds. Replacing seals is a common procedure for older convertibles.
- 🚗 Regularly lubricate the roof mechanism guides with special silicone grease to avoid squeaks and jamming.
- 🧼 Use only soft brushes and specialized chemicals to clean the fabric top, avoiding powerful high-pressure water jets at the joints.
- ❄️ Never try to fold the roof if it is frozen or there is snow on it - this is guaranteed to lead to a breakdown of the mechanism or tearing of the fabric.
It is also worth considering that a car without a top is more susceptible to heating the interior in hot weather. Even with the roof closed, the glass area and thin layer of insulation contribute to a rapid rise in temperature. Therefore, the presence of effective climate control and solar control glass becomes a critical factor in comfort.
☑️ Checking the convertible before purchasing
Safety and Myths
There is a persistent myth that a car without a top is not safe. People are afraid of tipping over or foreign objects getting into the cabin. However, modern safety standards (Euro NCAP, IIHS) force manufacturers to pay enormous attention to this aspect. Almost all modern convertibles and roadsters are equipped with automatic transmissions. roll bars (roll bars) that shoot out from the headrests in a fraction of a second when an impact or roll sensor is detected.
In addition, the A-pillars and windshield are made of particularly durable materials that can withstand the weight of an overturned vehicle. In some models, for example BMW or Mazda, the roll bars are part of the design and are not hidden. This is not only an element of safety, but also a stylistic feature that emphasizes its belonging to the class of open cars.
⚠️ Warning: Do not rely solely on the standard safety systems when driving at high speeds with the top down. Always wear your seat belts, as during sudden maneuvers or braking, the absence of a roof changes the aerodynamics of the body and can increase the risk of being thrown out of the passenger compartment if the belt is not tightened tightly.
Another aspect of security is visibility. In convertibles with the top down, visibility is often improved by eliminating the top frames of the windows. However, glare from the sun can blind the driver more often than in a regular car. The use of quality polarized glasses and visors becomes a necessity for long trips.
Conclusion: is the game worth the candle?
A car without a top is not just a vehicle, it is a certain way of life and philosophy. It gives an incomparable feeling of freedom, allows you to hear the sound of rain, smell the sea or autumn leaves, which is impossible in a sealed sedan. Yes, such cars require more careful maintenance, they can be noisier and more expensive to maintain, but the emotions they give outweigh all the disadvantages for many.
Choosing between convertible, roadster or targoi, focus on your real needs. If you live in an area with short summers and frequent rainfall, a hardtop convertible might be more practical. If you are a fan of drive and weekend trips together, the roadster will be your ideal companion. The main thing is that, regardless of the name, all these cars have one thing in common - the desire to be closer to nature and the road.
If you're buying a convertible as the only car in your family, choose a convertible hardtop model. It will provide better protection from coal miners and heat in winter, turning the car into a full-fledged coupe in the cold season.
How often do the seals on a convertible need to be replaced?
The service life of rubber seals depends on the climate and care. On average they last 5-7 years. Signs of wear: whistling at speed, water leaking into the interior during washing or rain. To extend life, use rubber conditioners.
Is it possible to wash a convertible in an automatic car wash?
Strongly not recommended. Automatic car wash brushes can damage the fabric or compromise the seals of your hardtop. It is better to use a self-service car wash with a soft cycle or a hand wash.
Is it true that a convertible is cold in winter?
Modern convertibles with double layers of fabric or hardtops, as well as powerful heating systems (including Mercedes' "Airscarf" neck heating) allow comfortable winter driving with the top closed. Problems with heat loss are only relevant for very old models.
What to do if the roof mechanism is jammed?
Do not forcefully close or open the roof. The vehicle manual (Emergency Operation section) describes the procedure for manual folding/unfolding using special keys or cables. After this, you need to contact a service for hydraulic or electrical diagnostics.
