BEETLE CABRIOLET
It was in 1948 that Wilhelm Karmann first bought a VW Beetle sedan and converted it into a four-seated convertible. After successfully presenting it at VW in Wolfsburg the Beetle Cabriolet began production in 1949 by Karmann in Osnabrück.
The convertible was more than a Beetle with a folding top. To compensate for the strength lost in removing the roof, the sills were reinforced with welded U-channel rails, a transverse beam was fitted below the front edge of the rear seat cushion, and the side cowl-panels below the instrument panel were double-wall. In addition, the lower corners of the door apertures had welded-in curved gussets, and the doors had secondary alignment wedges at the B-pillar.
The top was cabriolet-style with a full inner headliner hiding the folding mechanism and crossbars. In between the two top layers was 1 in (25 mm) of insulation. The rear window was tempered safety glass, and after 1968, heated. Due to the thickness of the top, it remained quite tall when folded. To enable the driver to see over the lowered top, the inside rearview was mounted on an offset pivot. By twisting the mirror 180 degrees on a longitudinal axis, the mirror glass would raise approximately 2 in (5.1 cm).
The convertible was generally more lavishly equipped than the sedan with dual rear ashtrays, twin map pockets, a visor vanity mirror on the passenger side, rear stone shields, and through 1969, wheel trim rings. Many of these items did not become available on other Beetles until the advent of the optional "L" (Luxus) Package of 1970.
After a number of stylistic and technical alterations made to the Karmann cabriolet, (corresponding to the many changes VW made to the Beetle throughout its history), the last of 331,847 cabriolets came off the production line on 10 January 1980.
1950-1959 MODELS
During this period, a myriad of changes were made throughout the vehicle beginning with the availability of hydraulic brakes and a folding fabric sunroof in 1950. The rear window of the VW Beetle evolved from a divided or "split" oval, to a singular oval. The change occurred between October 1952 and March 1953. Beetles built during this time were known as a "Zwitter", or "hybrid", as they used the split-window bodyshell with oval-model chrome trim, vent windows and dashboard.
1953 models received a redesigned instrument panel. The one-piece “Pope's Nose” combination license plate/brake light was replaced by a smaller flat-bottomed license plate light. The brake light function was transferred to new heart-shaped lamps located in the top of the taillight housings.
In 1954, Volkswagen added 2 mm (0.079 in) to the cylinder bore, increasing the displacement from 1,131 (1100) cc to 1,192 (1200) cc. This coincided with upgrades to various key components including a redesign of the crankshaft. This increased power from 30 hp (22 kW; 30 PS) to 36 hp (27 kW; 36 PS) and improved the engine's free revving abilities without compromising torque at lower engine speeds. At the same time, compression ratios were progressively raised as, little by little, the octane ratings of available fuel was raised in major markets during the 1950s and 1960s.
In 1955, the separate brake lights were discontinued and were combined into a new larger taillight housing. The traditional VW semaphore turn signals were replaced by conventional flashing directional indicator lamps for North America.
For 1956, the Beetle received what would become one of its more distinctive features, a set of twin chrome tailpipes. Models for North America gained taller bumper guards and tubular overrider bars..
For 1958, the Beetle received a revised instrument panel, and a larger rectangular rear window replaced the previous oval design.
1960-1969
1960 models received a front anti roll bar along with hydraulic steering damper.
For 1961, significant technical advances occurred in the form of a new engine and transmission. The engine remained at 1,192 cc (1.2 L; 72.7 cu in) but the power increased to 40 bhp (41 PS; 30 kW) at 3900 rpm and 88 N⋅m (65 lb⋅ft) at 2400 rpm of torque[70] primarily due to an increase in compression ratio to 7.1:1. The single-barrel Solex carburetor received an electric automatic choke and the transmission was now synchronized on all forward gears. The traditional semaphore turn signals were replaced by conventional flashing directional indicators worldwide. The standard model called the TYPE 111-112, continued to use the 36 hp 1200 engine of the old architecture that dates back to Franz Reimspiess original design of 1937 all the way until the end of the 1965 model year. 1965 standard model in 1965 is called the "A" sedan.
For 1962, the Beetle received a mechanical fuel level gauge in place of the former fuel tap. The Standard model continued without a gas gauge until the end of the 1965 model year. At the rear, larger tail lights were introduced incorporating a separate amber turn signal section to meet new European standards (these turn signals remained red in the US market until 1973). The former hand-pump style windscreen washer was replaced by a new design using compressed air. A Schrader valve located on the washer fluid tank allowed the system to be charged at a filling station to the recommended 35 psi (2.4 bar).[71]
1964 models could be identified by a widened light housing on the engine lid over the rear license plate, however the standard model continued to use the old teardrop style to the end of the 1965 model run.
The largest change to date for the Beetle was in 1965: the majority of the body stampings were revised, which allowed for significantly larger windows. The windshield increased in area by 11% and was now slightly curved, rather than flat. Door windows increased accordingly by 6% (and door vent window edges were canted slightly back), rear side windows 17.5%, and the rear window 19.5%. The result was a more open, airy, modern look.
For 1966, the big news was an optional new 1300cc 50 hp (37 kW; 51 PS) engine in lieu of the previous 1200cc engine that had been the sole engine since 1954. Models so equipped carried a "1300" badge on the engine lid. The 1300cc engine was standard for North America.
For 1967, a yet-again larger-displacement engine was made available: 1500cc, 53 hp (40 kW; 54 PS) at 4,200 rpm.[10] 1200 and 1300 engines continued to be available, as many markets based their taxation on engine size.[10] 1500cc Beetles were equipped with front disc brakes and were identified with a "VW 1500" badge on the engine lid. North America received the 1500 engine as standard equipment, but did not receive front disc brakes. These models were identified by a "Volkswagen" badge on the engine lid.
The rear suspension was significantly revised and included a widened track, softer torsion bars and the addition of a unique Z-configuration equalizing torsion spring. On US, UK and Ireland models, the generator output was increased from 180 to 360 watts, and the entire electrical system was upgraded from 6 volts to 12 volts. The clutch disc also increased in size and changes were made to the flywheel. New equipment included a driver's armrest on the door and locking buttons on both doors. Safety improvements included two-speed windscreen wipers, reversing lights (in some markets), and a driver's side mirror. In accord with the newly enacted US Federal Motor Vehicle Safety Standard 108, North American models received a dual-circuit brake system, the clear glass headlamp covers were deleted; the headlamps were brought forward to the leading edge of the front fenders, and the sealed-beam units were exposed and surrounded by chrome bezels. In the rest of the world markets the 1967 model retained the older headlights. Another oddity of the 1967 North American market Beetle is the rear bumper overriders (towel rails) – the overriders have a different shape than the older models besides the one-year only engine decklid.[clarification needed] The Brazilian market model (Volkswagen Fusca) retained the pre-1967 headlamps until 1972
1968 was a year of major change. The most noticeable of which were the new larger, higher mounted C-section bumpers. At the rear, new larger taillamps were adopted and were able to accommodate reversing lamps, which were previously separate bumper-mounted units. Beetles worldwide received the '67 North American style vertical headlamp placement, but with replaceable-bulb headlamps compliant with ECE regulations rather than the US sealed beams. Other improvements were a new outside gas filler with spring-loaded flap, eliminating the need to open the trunk to refuel. The fuel gauge was integrated with the speedometer and was now electrically actuated rather than cable-operated. The windscreen washer was now pressured by the spare tire, which was to be maintained at a pressure of 42 psi (2.9 bar). A pressure valve in the connecting hose closed airflow to the fluid reservoir if spare tire pressure fell below 30 psi (2.1 bar), which was above the recommended pressures for the road tires. A ventilation system was introduced, which drew fresh air into the cabin from louvres on the front decklid. For improved shifting, the shift lever was shortened, stiffened and moved rearward by 78 mm (3.1 in).
A number of safety improvements were made in order to comply with new American safety regulations: these included trigger-operated outside door handles, a secondary front hood latch, collapsing steering column, soft vent window latches, rotary glove compartment latch and instrument panel knobs labeled with pictographs. US models received a padded instrument panel that was optional in other markets. To meet North American head restraint requirements, VW developed the industry's first high-back bucket seat.[citation needed] The Standard model 111-112, called the 1200 "A" still used the 1200 engine but for the first time for Europe it came with a 12 volt system.
A new 3-speed manumatic gear box with torque converter and vacuum-operated clutch became available mid-production year. The manumatic models received a vastly improved semi-trailing-arm rear suspension (also known as "independent rear suspension" although the earlier swing axle Beetles were also independent) and eliminated the need for the equalizing torsion spring. This new rear suspension layout would eventually become an option on later models. Beetles equipped with the automatic were identified with a "VW Automatic" badge on the engine lid and a matching decal in the rear window. In North America, the badging and decal were later revised to read, "Automatic Stick Shift".
For 1969, the only exterior change was the fuel filler flap no longer had a finger indentation due to a new interior-mounted fuel door release. For North America, the Beetle received a heated rear window, day/night mirror and the semi-trailing, independent suspension with double jointed swing axles as standard equipment. In other markets, manual transmission models retained a swing axle independent suspension which would continue until the end of German Beetle production.
1970-1979 MODELS
In 1970, a new "L" (Luxus) Package was introduced including, among other items, twin map pockets, dual rear ashtrays, full carpeting, a passenger-side visor vanity mirror, and rubber bumper moldings. The optional 1500 cc engine now came with an engine lid having two rows of cooling louvers, while the convertible's engine lid gained two additional sets for a total of four. For North America, the 1500 cc engine was enlarged to 1600 cc engine and produced 57 hp (43 kW; 58 PS).
There were two Beetles for the first time in 1971, the familiar standard Beetle and a new, larger version, different from the windscreen forward. All Beetles received an engine upgrade: the optional 1500 cc engine was replaced by a 1600 cc with twin-port cylinder heads and a larger, relocated oil cooler. The new engine produced 60 hp (45 kW; 61 PS). The ventilation system was improved with the original dash-top vents augmented by a second pair aimed directly at the driver and passenger. For the first time the system was a flow-through design with crescent-shaped air exits fitted behind the rear quarter windows. Airflow could be increased via an optional 2-speed fan. The standard Beetle was now badged as the VW 1300; when equipped with the 1600 engine, it was badged 1300 S, to avoided confusion with the Type 3, which wore VW 1600 badges.
The new, larger Beetle was sold as the 1302/1302 S, offering nearly 43% more luggage capacity, up from 140 liters in front to 260 (remaining at 140 in back)[74] A new MacPherson strut front suspension was incorporated, similar to what was used in the Type 4, and the front track was widened. The new suspension layout allowed the spare tire to be positioned flat under the trunk floor. Although the car had to be lengthened slightly to accomplish this, it allowed a reduction in turning radius. To gain additional trunk volume, the under-dash panel[clarification needed] was lowered, allowing the fuel tank to be shifted rearward. From the windscreen back the big Beetle was identical to its smaller progenitor, except for having the also new semi-trailing arm rear suspension as standard equipment. Overall, the bigger Beetle was 50 mm (2.0 in) longer, 35 mm (1.4 in) wider, and rode on a 20 mm (0.79 in)-longer wheelbase. Both Beetles were available with or without the L Package. The convertible was now based on the 1302 body. In North America, the 1302 was marketed as the Super Beetle and came only with the L Package and 1600 cc engine. While it lacked the front disc brakes that normally accompanied the larger motor, it was fitted with brake drums that were slightly larger than the standard Beetle. With the Super Beetle being sold as the premium model in North America, the standard Beetle, while retaining the same 1600 cc engine, was stripped of many of its earlier features in order to reduce the selling price. Bright window and running board moldings disappeared, along with the day/night mirror, horn ring, map pocket, locking glove box and miscellaneous other items.
1972 models had an 11% larger rear window (40 mm [1.6 in] taller), and the convertible engine lid with four rows of louvres was now used on all Beetles. Inside the vehicle, a four-spoke energy-absorbing steering wheel was introduced, the windshield wiper/washer knob was replaced in favor of a steering column stalk, and intermittent wipers were a new option available in selected markets. An engine compartment socket for the proprietary VW Diagnosis system was also introduced. The rear luggage area was fitted with a folding parcel shelf. A limited-edition Commemorative model was launched in celebration of the Beetle's passing the record of the Ford Model T as the world's most-produced automobile.[75] The Commemorative Beetle was a 1302 S finished in a special Marathon Blue Metallic paint and unique 4.5 x 15 styled steel wheels. In the U.S., it was marketed as the Super Beetle Baja Champion SE.
1973 models featured significantly enlarged "elephant foot" taillamps mounted in reshaped rear fenders. In the engine bay, the oil-bath air cleaner gave way to a dry element filter, and the generator was replaced with an alternator. The 1302/Super became the 1303 with a new taller wrap-around windscreen. The changes to the cowl and windshield resulted in slight redesign of the front hood. The instrument panel, formerly shared with the standard Beetle, was all-new and incorporated a raised speedometer pod, rocker-style switches and side-window defrosters. The limited-edition GSR (Gelb-Schwarzer Renner; German for "Yellow-Black Racer") was a 1303 S available only in Saturn Yellow paint equipped with special 5.5 in (140 mm) wide sport wheels fitted with 175/70-15 Pirelli Cinturato CN36 high-performance radial tires. Front and rear deck lids were finished in matte black, as was all exterior trim with the exception of the chrome headlamp bezels. Inside were corduroy and leatherette high-bolstered sport seats and a small diameter three-spoke steering wheel with padded leather rim and a small red VW logo on the bottom spoke. In North America, the GSR was sold as the Super Beetle Sports Bug. The North American model had body-color deck lids and was available in Marathon Blue Metallic in addition to Saturn Yellow. In some markets, the sport wheels (in both 4.5-inch and 5.5-inch widths), sport steering wheel and sport seats became available as stand-alone options.
For 1974, North American models received newly required 5 mph (8.0 km/h) impact bumpers mounted on self-restoring energy absorbers, which added approximately 25 mm (0.98 in) to the car's overall length. On the Super Beetle, the steering knuckle, and consequently the lower attachment point of the strut, was redesigned to improve handling and stability in the event of a tire blowout. A limited-edition Big Beetle was introduced based on the 1303 LS. Available in unique metallic paint colors, the car featured styled-steel 5.5 in (140 mm) wide sport wheels wrapped in 175/70-15 tires, corduroy seat inserts, upgraded loop-pile carpet, wood-look instrument panel trim and a padded steering wheel with bright accents. In the North American market, a limited-edition Sun Bug was introduced as a standard Beetle or Super Beetle. Both were finished in metallic gold and featured styled-steel 4.5 in (110 mm)-wide sport wheels. Inside were brown corduroy and leatherette seats, loop-pile carpet, and padded four-spoke deluxe steering wheel. The Super Beetle Sun Bug included a sliding-steel sunroof. Mid-year, the Love Bug was introduced for North America: based on the standard Beetle, it was available only in Phoenix Red or Ravenna Green (both colors shared with the VW-Porsche 914) with all exterior trim finished in matte black. A price leader, the Love Bug retailed for less than a standard Beetle.
In 1975, front turn indicators were moved from the top of the front fenders down into the bumper. At the rear, the license plate light housing was now molded of plastic with a ribbed top surface. To comply with tightening emission standards, the 1600 cc engine in Japanese and North American markets received Bosch L-Jetronic fuel injection, rather than the D-Jetronic system formerly used in the VW Type 3 and Type 4. The injected engine received a new muffler and in California a catalytic converter. This necessitated a bulge in the rear apron under the rear bumper and replaced the distinctive twin "pea shooter" tailpipes with a single offset pipe, making injected models identifiable at a glance. 5 mph (8.0 km/h) bumper-equipped North American models retained fender-top front indicators. The 1303 received rack and pinion steering. In North America, the 1303/Super Beetle sedan was moved upmarket and was now christened La Grande Bug. Similar to the Big Beetle of 1974, La Grande Bug was available in blue or green metallic paint in the U.S. and blue, green or gold metallic in Canada and was equipped with the same features as the 1974 Sun Bug. The "Volkswagen" script on the engine lid of all North American Beetles was replaced with a "Fuel Injection" badge.
In 1976, the 1303/La Grande Bug was discontinued, with the larger body continuing only in convertible form. To make up for the loss in North American markets, the standard Beetle was upgraded, regaining some of the features that were removed in 1971. In addition, the 2-speed ventilation fan was included, previously available in North America only on the larger Beetle. The automatic stickshift option was discontinued as well.
1977 models received new front seats with separate head restraints. This was the final model year for the Beetle sedan in North America. The convertible was offered in a "triple white" Champagne Edition in Alpine White with white top and interior with the padded deluxe steering wheel, tiger maple wood-grain dash trim and 4.5 in (110 mm) wide sport wheels. Approximately 1,000 Champagne Editions were produced.
For 1978, a new Champagne 2nd Edition convertible was launched, available in blue or red metallic paint with white leatherette interior. Features included the 4.5 in (110 mm) wide styled steel sport wheels, AM/FM radio, analog quartz clock, padded deluxe steering wheel and rosewood-grain instrument panel trim. Approximately 1,100 were produced.
In 1979, VW offered an Epilogue Edition of the convertible in triple black with features similar to the 1978 Champagne Edition. This would be the last year of convertible production worldwide as well as the final year for the Beetle in the USA and Canada.
