A convertible is an automobile body style with a flexibly operating roof that can convert between open-air or enclosed modes. Cars can come in a large variety of different body styles. Some are still in production while others are of historical interest only Roof designs are highly variable from the folding textile roof, known variously as the top, soft top, ragtop or hood — to the folding multi-sectional rigid roof known as a retractable hardtop, coupé convertible or coupé cabriolet.

Folding textile roof

The collapsible textile roof section (of cloth or vinyl) over an articulated folding frame may include linings such as a sound-deadening layer (e. g. ,Volkswagen Beetle) or interior cosmetic headliner (to hide the frame) (e. The Volkswagen Beetle, officially known as the type 1 and originally called ‘Käfer’ is an Economy car produced by the German auto maker Volkswagen g. ,Chrysler LeBaron) — or both — and may have electrical or electro-hydraulic mechanisms for raising the roof. The Chrysler LeBaron was introduced in 1977 as Chrysler 's lowest priced model and the name was used on various Chryslers until 1995 The erected top secures to the windshield frame header with manual latches (e. g. ,Mazda Miata), semi-manual latches, or fully automatic latches (e. Generations and overview Now in its third generation the MX5's first generation the NA, sold over 400000 units from 1989 to 1997 &mdash with a Straight-4 g. ,Volvo C70). The Volvo C70 is a two-door manufactured by Volvo Cars in two generations the first from model years 1997-2002 as Coupé and from 1997-2005 as a softop The folded convertible top is called the stack.

Pros and cons

Convertibles offer the flexibility of an open top in trade for:

{{cquote|To neutralize the loss of torsional rigidity inherent in any convertible, VW engineers cleverly took the basket-handle roll bar of the VW Cabrio, inverted it and placed it under the rear seat pedestal. The Volkswagen Eos is a four-seater Retractable hardtop coupe convertible introduced in 2006 as the successor to the Volkswagen Cabrio. A beefed-up windshield frame of hot-stamped ultra-high-strength steel is connected directly to the floor pan’s reinforced frame rails. Steel tubing provides more stiffness behind the doors for an extra layer of safety. Partly as a consequence, rear seat passengers have about 10 inches less shoulder room than in the smaller Rabbit"[1]

Tonneau covers

Folding textile convertible tops often do not hide completely the mechanism of the folded top or can expose the vulnerable underside of the folded top to sun exposure and fading — in which case tonneau covers (British: boot) of various designs snap or secure into place to protect the folded roof and hide the mechanicals. Detachable foldable, rigid or semi-rigid covers require space-consuming storage inside the vehicle — and sometimes complicated installation from outside the stationary vehicle. Foldable vinyl and cloth covers can be prone to shrinkage, further complicating installation.

Detachable hardtops

Convertibles such as both the first and eleventh generation of the Ford Thunderbird and the second and third generations of the Mercedes SL featured as standard or optional equipment fully rigid, manually installable hardtops — later examples including heatable rear windows. The Thunderbird is an automobile manufactured by Ford in the United States from 1955 through 2005 &mdash through thirteen generations and various The Mercedes-Benz SL is a Roadster manufactured by Mercedes since 1954 These hardtops provided acoustic insulation but also required space-consuming off-season storage — and a cumbersome two-person installation. The optional aluminum (i. e. , lightweight) detachable hardtop for a Porsche Boxster weighed 51 lbs. 986 The styling of the Boxster is due to former "Style Porsche" department head Harm Lagaay. [2]

Convertible windows

Convertible side windows have evolved from non-existent in the earliest models, to detachable side screens and manually or power operated glass side windows. Rear-windows have evolved similarly, with plastic rear-windows appearing as late as the first generation Porsche Boxster. 986 The styling of the Boxster is due to former "Style Porsche" department head Harm Lagaay. Contemporary convertibles and retractable hardtops feature heatable glass rear windows to maximize visiblity — though rear windows often can compromise visibility by their size, as with the case of the very small rear window and restricted visibility of the Mitsubishi Eclipse Spider. The Mitsubishi Eclipse is a four-seat sports Coupe that has been in production since 1989 for Left hand drive markets including the United States, Plastic windows can degrade, fade, yellow and crack over time, diminishing visibility.

Windblockers

Windblockers, also known as wind screens or wind deflectors, minimize unwanted drafts from reaching the occupants — specifically cold air rushing from behind the passengers having been forced over the windshield then returning to the natural lower-pressure zone where the passengers sit. The passage of wind by the occupants can create significant noise in the process.

Mazda pioneered the windblocker with its Mazda RX7 convertible featuring an integral rigid opaque panel that folded up from behind the two seats. The Mazda RX-7 is a Sports car produced by the Japanese automaker Mazda from 1978 to 2002 Current convertibles feature windblockers of various designs including detachable fold-up designs (e. g. ,Toyota Solara), vertically retractable glass (e. This page is about the automobile manufactured by Toyota For other uses see Solara (disambiguation The Toyota Camry Solara, also more commonly known as the g. ,Audi TT), carefully designed minimal flaps (e. The Audi TT is a Sports car manufactured by Audi since 1998 in Győr, Hungary, now in its second generation &mdash and available as a 2+2 g. ,Mazda Miata) — or other integrated wind controlling systems. Generations and overview Now in its third generation the MX5's first generation the NA, sold over 400000 units from 1989 to 1997 &mdash with a Straight-4

Mercedes currently offers a feature that routes a heating duct to the neck area of the seat on SLK and SL models, marketed as the "Air Scarf". The SLK is a compact Roadster manufactured by Mercedes-Benz in two generations R170 and R171, since 1997 The Mercedes-Benz SL is a Roadster manufactured by Mercedes since 1954

According to the chief engineer for 2008 Chrysler Sebring, Jim Issner, the windblocker for the Sebring reduces "wind noise by approximately 11 to 12 decibels. The decibel ( dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually power or intensity relative to "[3]

Safety

Contemporary convertible design may include such features as electrically-heated glass rear window (for improved visibility), seat belt pre-tensioners, boron steel reinforced A-pillers, front and side airbags, safety cage construction — a horseshoe like structure around the passenger compartment — and roll over protection structures or (ROPS) with pyrotechnically charged roll hoops hidden behind the rear seats that deploy under roll-over conditions whether the roof is retracted or not. A seat belt, sometimes called a safety belt, is a Safety harness designed to secure the occupant of a Vehicle against harmful movement that may result from Roll Over Protection Structure (ROPS refers to operator compartment structures (usually cabs or frames intended to protect equipment operators from injuries caused by vehicle overturns The term "pyrotechnics" can also be used for Fireworks events Roll bar redirects here For the suspension component called a roll bar see Sway bar.

Notably, the Volvo C70 retractable hardtop includes a door-mounted side impact protection inflatable curtain which inflates upward from the interior belt-line — vs. The Volvo C70 is a two-door manufactured by Volvo Cars in two generations the first from model years 1997-2002 as Coupé and from 1997-2005 as a softop downward like the typical curtain airbag. [4] The curtain has an extra stiff construction with double rows of slats that are slightly offset from each other. This allows them to remain upright and offer effective head protection even an open window. The curtain also deflates slowly to provide protection should the car roll over.

As an example of current convertible safety, the Citroën C3 Pluriel received the following European New Car Assessment Program (Euro NCAP) ratings:

Retractable hardtops

The retractable hardtop solves some issues with the convertible, but has its own compromises, namely mechanical complexity, expense and more often than not, reduced luggage capacity. The Citroën C3 is a Supermini car with a range of inline-4 engines that has been produced by the French automaker Citroën since 2002 The European New Car Assessment Programme (Euro NCAP is a European Car safety performance assessment programme founded in 1997 by the Transport Research A 2007 Wall Street Journal article suggested "more and more convertibles are eschewing soft cloth tops in favor of sophisticated folding metal roofs, making them practical in all climates, year-round. "[5]

Variations

Convertibles have offered numerous iterations that fall between the first mechanically-simple but attention-demanding fabric tops to the highly complex modern retractable hardtops:

Roadster: Originally the term roadster suggested a minimal convertible, possibly with a frame that required actual assembly (i. A roadster, also known as a spyder or spider, is a two-seater car traditionally without a roof (or with a detachable roof and no side or rear windows e. , not retracting) and separately installable soft "window" panels — offering little protection from inclement weather and requiring a time-consuming, complicated installation. A contemporary roadster is a two-seater convertible.

Landau & Rigid Door: Citroën's early Citroën 2CV featured a roof that rolled back on itself leaving rigidly framed side doors in place — followed in concept by such cars as the 1950 Nash Rambler Convertible Coupe. Citroën (pronounced See-Troh-Enn is a French Automobile manufacturer, founded in 1919 by André Citroën. The Citroën 2CV ( French: deux chevaux vapeur, literally "two steam Horses quot from the Tax horsepower rating was an Economy car

Citroën currently markets the C3 Pluriel (Pluriel is a cognate with the English plural), which can be configured into five iterations, hence the name: [6]

The Four Door: A four door converitble is referred to as a phaeton, while a two-door is referred to as a cabriolet. Modern 4-door models, e. g. , the Lincoln Continental, c. The Lincoln Continental, an automobile produced by the Lincoln division of Ford Motor Company, began for the 1939 model year 1960.

Peugeot presented the a concept four-door retractable hardtop convertible, the Peugeot 407 Macarena in 2006. The Peugeot 407 is a Large family car produced by the French automaker Peugeot since 2004 [8] Produced by French coachbuilding specialist Heuliez, the Macarena's top can be folded in 60 seconds, [8] with a steel reinforcing beam behind the front seats incorporating LCD screens for the rear passengers into the crossmember. Heuliez is a French company that works as a production and design unit for various automakers [8]

Drophead Coupe, Cabriolet or Cabrio: A type of convertible with only two doors [9] and thereby recalling the cabriolet carriage. A cabriolet is a light two-wheeled Carriage drawn by a single horse with a folding hood seating two people facing forward one of whom is the driver With its Mazda RX7 convertible, Mazda introduced a two-seater convertible with a removeable rigid section over the passengers, removable independently of power operated textile section behind with heatable glass rear window. The Mazda RX-7 is a Sports car produced by the Japanese automaker Mazda from 1978 to 2002 During the 80's, Jaguar produced an XJ-SC with two removable panels over the front seats and a partial fold-down convertible section in the back. The jaguar (Panthera onca,, or—especially in British English — is a New World Mammal of the Felidae family and one of It retained the rear side windows of the coupe and had fixed cant rails above these and the door glass. This allowed an almost full convertible with roll over safety.

History in the United States

Until the 1910 introduction by Cadillac of the first closed-body car, the convertible was the primary body style. Cadillac is a Brand of Luxury vehicles owned by General Motors. US automakers manufactured a broad range of models during the 1950s and 1960s — from economical compact-sized models such as the Rambler American and the Studebaker Lark to the more expensive models such as the Packard Caribbean, Oldsmobile 98, and Imperial by Chrysler. The Rambler American was an automobile manufactured by the American Motors Corporation (AMC between 1958 and 1969 The Lark was a pioneering " Compact car " designed and built by Studebaker and introduced as a 1959 model The Packard Caribbean was a Halo vehicle produced by the Packard Motor Car Company of Detroit Michigan during model years 1953 through 1956 The Oldsmobile 98 (originally Series 90; aka Ninety-Eight) was a full-size Automobile, as well as the flagship model of the for Chrysler branded models before 1955 and after 1983 see Chrysler Imperial Imperial was the Chrysler Corporation 's prestige

Threatened rollover safety regulations in the mid-1970s led to diminished popularity by the 1970s. This article is about the Decade 1970-1979 For the Year 1970 see 1970.

A T-top is an automobile roof with removable panels on either side of a rigid bar running from the center of one structural bar between pillars to the center of the next structural

Elsewhere globally, convertible production continued throughout this era with models such as the Mercedes SL, the VW Beetle Cabriolet, the VW Golf Cabriolet, and the Jaguar E-type. The Mercedes-Benz SL is a Roadster manufactured by Mercedes since 1954 The Volkswagen Beetle, officially known as the type 1 and originally called ‘Käfer’ is an Economy car produced by the German auto maker Volkswagen The Volkswagen Golf or VW Golf ( Mk1 and Mk5 badged as Volkswagen Rabbit in the United States and Canada, Mk1 badged as Volkswagen The Jaguar E-Type' (UK or XK-E (US is a British Automobile, manufactured by Jaguar between 1961 and 1974

In the 1980s convertibles such as the Chrysler LeBaron and Saab 900 revived the body style in the United States — followed by models such as the Mazda Miata, Porsche Boxster, Audi TT and later retractable hardtop models. The Chrysler LeBaron was introduced in 1977 as Chrysler 's lowest priced model and the name was used on various Chryslers until 1995 The 900 is a car that was made by Saab Automobile from 1978 until 1998 in two generations Generations and overview Now in its third generation the MX5's first generation the NA, sold over 400000 units from 1989 to 1997 &mdash with a Straight-4 986 The styling of the Boxster is due to former "Style Porsche" department head Harm Lagaay.
