VW Polo, 1975

VW Polo, 1975

 

The Mk I Polo, a rebadged version of the Audi 50, was introduced in 1975. The differences between the Audi and VW models were minor, with the Polo being cheaper and much more basic. The two cars were initially sold along side each other, but the Audi 50 never sold as well, and was withdrawn in 1978. The Polo was manufactured at the Volkswagen plant in Wolfsburg. In 1977, the Derby sedan was released, which was simply a Polo, identical to the hatchback from the C-pillar forward, with a large boot attached (an old Audi proposal, but never sold by this brand).

When first on sale the range topping car, the LS model, featured the 50 PS (37 kW) 1043 cc engine found in the Audi 50. Other specifications included parking lights, rear wash wipe, sun visors, chromed bumpers and 4.5J X 13" wheels. The N model was the basic starting spec lacking many of the features of the LS. In 1979 the GLS was introduced, replacing the LS as the range-topping car; specification upgrades included chrome headlight and grill surrounds, sunroof, a cigarette lighter and chrome wheel trims.

895 cc, 1093 cc and 1272 cc engines were used, with the smaller one used only in the Polo hatchback, and the 1272 cc only in the Derby, Audi 50, and the rare Polo GT. Different levels of compression were used on each size to achieve different power outputs, and the variations are numerous, often differing depending on the country of sale, ranging from 35 to 60 PS (26 to 44 kW).

Mk IF (1979-1981)
The Mk I Polo and Derby were facelifted in 1979 (Mk IF) with plastic bumpers, a different front grille and a revised dashboard. The round headlights of the Derby were replaced with square ones, bringing it inline with the similar Golf-based Jetta sedan.

VW Golf I, 1974

VW Golf I, 1974

 

The first Golf began production in 1974. Marketed in the United States and Canada from 1975 to 1984 as the Volkswagen Rabbit and in Latin America as the Volkswagen Caribe, it featured the water-cooled, front wheel drive design pioneered by the Citroën Traction Avant in 1934 with the addition of a hatchback pioneered by the Renault 4 in 1961. The Golf was Wheels magazine's Car of the Year for 1975. The name is short for Golf-Strom, German for Gulf Stream; it was named for that oceanic current to reflect its international character. It was originally named the Rabbit in North America and the Caribe in Latin America, ironically, because marketers decided that no one in the Western Hemisphere would understand the European name.

While the Golf was not the first design with this layout (earlier examples being the Austin and Morris Mini of 1959, the Austin Maxi in the late 1960s and the Fiat 128 3P of the early 1970s), it was very successful, especially since it married these features with Volkswagen's reputation for solid build-quality and reliable engineering.

The Golf was designed by Italian automobile architect / designer Giorgetto Giugiaro, of the ItalDesign design studio. A version of this original Golf model, known as the Volkswagen CitiGolf, is still produced in South Africa as an entry level car.

In 1978, Volkswagen commenced producing the Rabbit version of the Mk1 Golf in Westmoreland County, Pennsylvania, thus becoming the first European car manufacturer in modern times to produce a vehicle in the United States. Former Chevrolet executive James McLernon was chosen to run the factory, which was built to lower the cost of the Rabbit in North America by producing it locally. Unfortunately, McLernon tried to "Americanize" the Rabbit by softening the suspension and using cheaper materials for the interior. VW purists in America and company executives in Germany were displeased, and for the 1983 model year the Pennsylvania plant went back to using stiffer shocks and suspension with higher-quality interior trim. The plant also began producing the GTI for the North American market. (Rabbits were built in Pennsylvania through 1984.) The first VW Caddy pick-up, based on the Mk1 Golf, was also created at the Pennsylvania plant.

The GTI version, launched in Europe in 1976 and in the US in 1983, virtually created the hot hatch genre overnight, and many other manufacturers since have created special sports models of their regular volume selling small hatchbacks. It was one of the first small cars to adopt fuel injection for its sports version, which raised power output of the 1588 cc engine to 110 PS (81 kW/108 hp). In 2004, Sports Car International announced the GTI Mk I as the 3rd best car of the 1980s. In the United States, the Mk1 Golf GTI was known as the Rabbit GTI.

There was a minor facelift in 1980 for North American versions only, which saw the adoption of larger rear lamp clusters (more in line with Guigiaro's original concepts), larger bumpers, square headlights and a new dashboard with a more modern-looking instrument display.

The convertible version, named the Cabriolet, was sold from 1980 to 1993 (a convertible version of the Golf II was not made, so the Mk1 cabrio with slight modification was produced until the introduction of the Mk III cabrio). It had a reinforced body, transverse roll bar, and a high level of trim. The A1 Volkswagen convertible is of unibody construction built entirely at the factory of Karmann, from stamping to final assembly; Volkswagen supplied the engine, suspension, interior, etc. for Karmann to install. The vinyl tops were insulated and manually operated, with a glass rear window.

VW Passat Variant, 1973

VW Passat Variant, 1973

The original VW Passat was launched in 1973. The body types offered originally were 2- and 4-door sedans and similar looking three- and five-door versions. Externally all four shared a modern fastback style design, styled by the Italian designer Giorgetto Giugiaro). All the versions sharing the same external design was unusual, since two of the models were traditional sedans with a separate trunk. A five-door station wagon was introduced in 1974. Passat was effectively a less expensive version of the Audi 80 (Fox) sedan which had been introduced a year earlier and which had a more conservative body style, so that the Audi and Volkswagen models had distinct body styles and image. In Europe, Passat was equipped with hexagonal or single round or double round headlights depending on specification.

In North America, the car was called the Dasher, and was only available with round DOT-spec lights. The three-door hatchback model was launched in North America in 1975.

VW Passat was one of the most modern European family cars at the time, and was intended as a replacement for the ageing Volkswagen Type 3, and as a contemporary rival for popular Ford Taunus/Cortina) and Opel Ascona/Vauxhall Cavalier. The Passat was Wheels magazine's Car of the Year for 1974 and its sister model Audi 80 was nominated car of the year by the European motor press a year earlier. The platform was named B1.

The Passat used the 4 cylinder OHC 1.3 L, 1.5 L, and 1.6 L petrol engines, also used in the Audi 80—longitudinally mounted with front wheel drive, in Audi tradition, with either a 4-speed manual transmission or 3-speed automatic. It had a MacPherson strut front suspension with a solid axle/coil spring setup in back.

The SOHC 1.5 produced 75 PS (55 kW) and was enlarged to 1.6 L for 1975. The larger engine included tighter emissions controls, so power output dropped to 70 PS (52 kW). Bosch fuel injection on the 1.6 was introduced in 1976 and brought power up to 78 PS (57 kW).

The whole range received a facelift in 1977 (launched 1978 outside Europe), featuring an interior upgrade and subtly revised styling including repositioned indicators and quad (round) headlights on all models. This generation was sold in Brazil well into the 1980s and extensively exported to Iraq, where many are still on the road. It was also assembled in Nigeria.

1979 saw the introduction of the Volkswagen Golf's 1.5 L Diesel engine, which produced just 48 PS (35 kW) in the 1130 kg (2500 lb) car. 0–100 km/h time for the Diesel was 19.4 seconds, 6.2 seconds slower than the gasoline (petrol) engine.

Pontiac GTO, 1970

Pontiac GTO, 1970

The Pontiac GTO was an automobile built by Pontiac from 1964 to 1974, and by General Motors Holden in Australia from 2003 to 2006. It is often considered the first true muscle car. From 1964 until 1973.5, it was closely related to the Pontiac Tempest, but for its final year it was based on the Pontiac Ventura. The 21st century GTO is essentially a left hand drive Holden Monaro, itself a coupe variant of the Holden Commodore.

Second generation
1968
GM redesigned its A-body line for 1968, with more curvaceous, "bustleback" fastback styling. The previous 115 inch (292 cm) wheelbase was shortened to 112 inches (284 cm) for all two-door models. Overall length was reduced 5.9 inches (150 mm) and height dropped half an inch (12 mm), but overall weight was up about 75 pounds (34 kg). Pontiac abandoned the familiar stacked headlights for hidden headlights behind the split grille (actually a US$52.66 option, but seen on many GTOs). The signature hood scoop was replaced by dual scoops on either side of a prominent hood bulge extending from the protruding nose.

Powertrain options remained substantially the same as in 1967, but the standard GTO engine rose to 350 hp (261 kW) @ 5,000 rpm. At mid-year, a new Ram Air package became available with freer-breathing cylinder heads, round port exhaust and the 744 cam and 3.90:1 rear differential. Horsepower rating was not changed, although actual output was likely somewhat higher, especially with open exhausts. Another carry-over from 1967 was the 4-piston caliper disc brake option. While most 1968 models had drum brakes all around, this rare option provided greater stopping power and could be found on other GM A-Body vehicles of the same period. 1968 was also the last year the GTOs offered separate vent, or "wing", windows—and the only year for crank-operated vent windows.

1969
The 1969 model did not have the vent windows, had a slight grille and taillight revision, moved the ignition key from the dashboard to the steering column, and the gauge faces changed from steel blue to black. In addition, the rear quarter-panel mounted side marker lamps changed from a red lens shaped like the Pontiac "V" crest to one shaped like the broad GTO badge.

The previous economy engine and standard 350 hp 400 in³ V8 remained, but the 360 hp engine was dropped in favor of a pair of new Ram Air engines. The 400 in³ Ram Air III was rated at 366 hp (273 kW) @ 5,100 rpm, while the top option was the 370 hp (276 kW) Ram Air IV, which featured special header-like high-flow exhaust manifolds, high-flow cylinder heads, a specific high-rise aluminum intake manifold, larger Rochester QuadraJet four-barrel carburetor, high-lift/long-duration camshaft, forged steel crankshaft plus various internal components capable of withstanding higher engine speeds and power output. Unlike the big-block Chevy and Hemi motors, the Ram Air IV utilized hydraulic lifters. As a result, it did not overheat in traffic, nor did it foul spark plugs, which set it apart from the large-displacement performance engines seen in other muscle cars.

1970
The Tempest line received another facelift for the 1970 model year. Hidden headlights were deleted in favor of four exposed round headlamps outboard of narrower grille openings. The nose retained the protruding vertical prow theme, although it was less prominent. While the standard Tempest and LeMans had chrome grilles, the GTO retained the Endura urethane cover around the headlamps and grille.

The suspension was upgraded with the addition of a rear anti-roll bar, essentially the same bar as used on the Oldsmobile 442 and Buick Gran Sport. The front anti-roll bar was slightly stiffer. The result was a useful reduction in body lean in turns and a modest reduction of understeer.

Another handling-related improvement was optional variable-ratio power steering. Rather than a fixed ratio of 17.5:1, requiring four turns lock-to-lock, the new system varied its ratio from 14.6:1 to 18.9:1, needing 3.5 turns lock-to-lock. Turning diameter was reduced from 40.9 feet (12.5 m) to 37.4 feet (11.4 m).

The Judge remained available as a separate model. The Judge came standard with the Ram Air III, while the Ram Air IV was optional. Though the 455 in³ was available as an option on the standard GTO throughout the entire model year, the 455 was not offered on The Judge until late in the year. "Orbit Orange" became the new standard color for the '70 Judge, but any GTO color was available on The Judge. Striping was relocated to the upper wheelwell brows.

An Orbit Orange 1970 GTO Judge with the 455 engine and Turbo Hydra-Matic transmission was one of the featured cars in the movie "Two-Lane Blacktop", which depicted a cross-country race between the new GTO and a 1955 Chevrolet Bel Air.

The new styling did little to help declining sales, which were now being hit by sagging buyer interest in all musclecars and by the punitive surcharges levied by automobile insurance companies, which sometimes resulted in insurance payments higher than car payments for some drivers. Sales were down to 40,149, of which 3,797 were The Judge. The GTO remained the third best-selling intermediate musclecar, outsold by the Chevrolet Chevelle SS 396/454 and Plymouth Road Runner.
