The Avenger GT was a kit car produced by Fiberfab. It was designed in California and manufactured in the United States and Canada for 12 years, from late 1966 until 1978.
The Avenger GT was the successor to the Aztec in Fiberfab's lineup. Some of the company's early documentation refers to it as the Aztec Avenger GT. [1] The Avenger GT's styling recalls the Ford GT40 — the Mk.I and Mk.III GT40s in particular — but is not an exact copy of the racing car. It was a less expensive alternative to the Fiberfab Valkyrie, which looked like an Avenger GT with a short rear deck and had a custom chassis with room for a mid-mounted V8 engine. [2]
Fiberfab started producing Avenger GT kits in Sunnyvale, California in Santa Clara County in 1966. [3] They moved to Fremont, California in 1967. They also had a facility in Bridgeville, PA to supply demand on the East coast.
A separate company called Fiberfab Canada Limited (FCL) was incorporated in Canada and after 1970 began producing long door Avenger GT kits in a facility in Dauphin, Manitoba. This operation relocated to Winnipeg, Manitoba in 1971, and then to Ontario in 1974.
Production of Avenger GTs ended in 1978. [2] The total number of kits made was in the thousands. [4]
Instead of the two single lamps fitted to the Aztec, the Avenger GT was equipped with quad headlamps. The Avenger GT's tail section was longer than the Valkyrie's so that it could cover the car's rear-mounted engine, giving it an appearance closer to that of a GT40 Mk.III.
The Avenger GT's windshield is the standard unit from a second generation (1965–69) Chevy Corvair, while the backlight is from a 1965 or 1966 Ford Mustang 2+2 Fastback.
There were several options for side windows. The original Fiberfab manuals described an arrangement that used a wind-wing from a 1965 Mustang in combination with door glass from a 1966 Ford LTD and a regulator from a VW Karman Ghia. Another option used a custom single piece glass side window supplied by Fiberfab, but the original molds for this were lost. Side windows from Plexiglass or Lexan were special order items.
There are long door cars and short door cars. The short door cars were built prior to 1970, and have a rocker panel below the door edge. The long door reaches all the way to the bottom of the car body and is a bit wider.
The earliest models could be ordered with or without the GT40 style twin hood scoops.
The choice of taillamps was left up to the builder, some of whom used early Mustang or Maverick units.
The Avenger GT line included two models: the Avenger GT-12, and the Avenger GT-15. [5]
The GT-12 was designed to be built on a Volkswagen Type 1 backbone chassis from a Volkswagen Beetle or Karmann Ghia, adjusted for width as necessary. [1] With the chassis came the donor VW's front suspension of upper and lower trailing arms, torsion leaf springs and telescopic shock absorbers, and rear suspension of swing axle or semi-trailing arms, torsion bars and telescopic shocks. The donor car's original 4-speed transaxle and four cylinder Volkswagen air-cooled engine could be kept, but other options, including Porsche or Corvair engines, could be substituted. At roughly 1,500 lb (680.4 kg), the GT-12 weighed approximately 500 lb (226.8 kg) less than a standard Beetle.
The GT-15 was similar in appearance to the GT-12, but included a custom chassis designed to accept suspension and drive-train components from a Chevrolet Corvair. [6] Installing a Corvair front sub-frame put upper and lower A-arms with coil springs and telescopic shocks in front, with or without an Anti-roll bar. At the rear was a semi-trailing arm suspension with coil springs and telescopic shocks. The default rear-mounted Chevrolet Turbo-Air 6 engine provided power through a 3 or 4-speed manual Chevrolet transaxle.
Later models of the Avenger GT were designated with an X and received minor body revisions. These usually included long-style doors, flared wheel arches, and a front spoiler.
To test electric vehicle propulsion systems using a special dynamomoter called the "Road Load Simulator" (RLS), NASA commissioned construction of a special vehicle that was designed from the outset as an electric vehicle. [7] A custom ladder chassis with outriggers was built by "Electric Vehicle Engineering Co." (EVE) of Boston, Massachusetts. Configured for front wheel drive, the car's running gear was from Saab. The body was a Fiberfab shell, and appears to have been an Avenger GT.
The Ford GT40 is a high-performance mid-engined racing car originally designed and built for and by the Ford Motor Company to compete in 1960s European endurance racing. Its specific impetus was to best Scuderia Ferrari, which had won the prestigious 24 Hours of Le Mans race for six years running from 1960 to 1965. Around 100 cars have been made, mostly as 289 cu in (4.7 L) V8-powered Mk Is, some sold to private teams or as road legal Mk III cars. Racing started in 1964, with Ford winning World Championships categories from 1966 to 1968. The first Le Mans win came in 1966 with two 427 cu in (7.0 L) powered Mk.II prototypes crossing the finish line together, the second in 1967 by a similarly powered highly modified US-built Mk.IV "J-car" prototype. In order to lower ever-higher race top speeds, a rule change from 1968 onwards limited prototypes to 3.0 litre Formula 1 engines; a loophole, however, allowed the private JW "Gulf Oil" team win at Le Mans in 1968 and 1969 running a Mk.I with a 5.0 litre engines.
The Chevrolet Corvair is a rear-engined, air-cooled compact car manufactured by Chevrolet in two generations between 1960 and 1969. A response to the Volkswagen Beetle, it was produced in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964), and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969). Total production was approximately 1.8 million vehicles from 1960 until 1969.
The Ford GT is a mid-engine two-seater sports car manufactured and marketed by American automobile manufacturer Ford for the 2005 model year in conjunction with the company's 2003 centenary. The second generation Ford GT became available for the 2017 model year.
The Volkswagen Type 3 is a compact car manufactured and marketed by Volkswagen from 1961 to 1973. Introduced at the 1961 Frankfurt International Motor Show, the IAA, the Type 3 was marketed as the Volkswagen 1500 and later as the Volkswagen 1600, in two-door notchback, fastback, and station wagon body styles, the latter marketed as the 'Squareback' in the United States.
In automotive design, an RR, or rear-engine, rear-wheel-drive layout places both the engine and drive wheels at ushered dirrurthe rear of the vehicle. In contrast to the RMR layout, the center of mass of the engine is between the rear axle and the rear bumper. Although very common in transit buses and coaches due to the elimination of the drive shaft with low-floor buses, this layout has become increasingly rare in passenger cars.
A transaxle is a single mechanical device which combines the functions of an automobile's transmission, axle, and differential into one integrated assembly. It can be produced in both manual and automatic versions.
A swing axle is a simple type of independent suspension designed and patented by Edmund Rumpler in 1903 for the rear axle of rear wheel drive vehicles. This was a revolutionary invention in automotive suspension, allowing driven (powered) wheels to follow uneven road surfaces independently, thus enabling the vehicle's wheels to maintain better road contact and holding; plus each wheel's reduced unsprung weight means their movements have less impact on the vehicle as a whole. The first automotive application was the Rumpler Tropfenwagen, another early example was the 1923 Tatra 11 later followed by the Mercedes 130H/150H/170H, the Standard Superior, the pre-facelift Volkswagen Beetle and most of its derivatives, the Chevrolet Corvair, and the roll-over prone M151 jeep amongst others.
The Chevrolet Turbo-Air 6 is a flat-six air-cooled automobile engine developed by General Motors (GM) in the late 1950s for use in the rear-engined Chevrolet Corvair of the 1960s. It was used in the entire Corvair line, as well as a wide variety of other applications.
The Volkswagen SP2 is a sports car that was developed by Volkswagen do Brasil and built from July 1972 until December 1975. It is based on the chassis of the Brazilian market Volkswagen Type 3. "SP" is said to be an initialism of São Paulo, where the car was built, or of "sports prototype". In its issue of 20 June 1973, German technology magazine Hobby called the SP2 the "most beautiful Volkswagen in the world".
Chevrolet used the name Chevrolet Greenbrier for two distinct vehicles. The first was a six-to-nine-passenger window van version of the Corvair "95" panel van. The Corvair 95 series also included the Loadside and Rampside pickup trucks, featuring a mid-body ramp on the right side. These variants used the Corvair powertrain in a truck body. Production of these vans was from 1961 until 1965.
The Valkyrie is a GT sports car introduced in 1966 by the Fiberfab company. The Valkyrie's styling was inspired by the lines of the Ford GT40.
The Spectre R42 is a 2-seater mid-engined rear-wheel drive sports car manufactured by British boutique automobile manufacturer Spectre Supersports Ltd.
Manta Cars was owned and operated by American brothers Brad and Tim LoVette, and was located in Costa Mesa, California, from 1974 to 1986. Manta produced the Manta Mirage, and later produced other component kit cars, including the rear-engined Volkswagen Beetle-based Manta Montage, and the mid-engined Montage-T, which had a custom space frame chassis and used GM X-body V6 drivetrains. The Montage-T recreated the elusive McLaren M6GT.
Devin Enterprises was an American automotive manufacturer that operated from 1955 to 1964. Devin was mainly known for producing high quality fiberglass car bodies that were sold as kits, but they also produced automotive accessories as well as complete automobiles. The company was founded by Bill Devin.
Fiberfab was an American automotive manufacturer established in 1964. Starting with accessories and body parts, they progressed to making kit cars and fully assembled automobiles. They became one of the longest lasting kit car manufacturers.
The ChevroletCorvair Monza GT (XP-777) was a mid-engine experimental prototype automobile built by General Motors in 1962 and based on the early model Chevrolet Corvair series. As it was essentially a concept car, the Monza GT did not enter production.
Kelmark Engineering was an American automotive specialty shop established in 1969 and based in Okemos, Michigan. It focused on high-performance custom V8 drivetrain swaps, the modification and production of rear and mid-engined cars, and custom-built turn-key automobiles. Until 1986, Kelmark Engineering manufactured kits and complete, finished, turn-key vehicles which were either Volkswagen-based or built on tubular race car-type frames. The outfit gained its name from Jim Kellison and Randy Markham, the two co-creators who started the operation. Up until at least 1989, the Kelmark GT was still available as a kit albeit the manufacturer was Kelmark Motors in Holt, Michigan. The cars are all "rare" models, but the Volkswagen-powered Kelmark GT was the most popular.
The Blakely Bernardi is an automobile produced in the 1980s by Blakely Auto Works of Princeton, Wisconsin, USA. Blakely produced a number of automobile models, including the Bearcat and Bantam. This model is named after Enrico Bernardi, Italian inventor of the gasoline internal-combustion engine and automobile pioneer. The Bernardi was available as a completed car or as a kit of parts to be assembled by the buyer.
The AC 3000ME is a mid-engined sports car originally sold by AC Cars. The two-door coupé debuted at the 1973 London Motor Show. Sales did not begin until 1979 and lasted until 1984. Rights to the 3000ME and tooling were transferred to a second company who managed to produce a small number of additional cars before going into receivership themselves in mid-1985. A third company acquired the rights to the car with plans to begin selling a revised version under a different name, but only a single prototype was ever produced.
Heron Cars were racing cars, sports and kit cars built in New Zealand between 1962 and 1999 by Ross Baker. They also included a one-off electric car.
