Late in 1971, Ford began importing Panteras for the American market to be sold through its Lincoln Mercury dealers. The first 75 cars were simply European imports and are known for their "push-button" door handles and hand-built Carrozzeria Vignale bodies. A total of 1,007 Panteras reached the United States that first year. These cars were poorly built, and several Panteras broke down during testing on Ford's test track. Early crash testing at UCLA showed that safety cage engineering was not very well understood in the 1970s. Rust-proofing was minimal on these early cars, and the quality of fit and finish was poor, with large amounts of body solder being used to cover body panel flaws. Notably, Elvis Presley once fired a gun at his Pantera after he flooded it and it would not start.
Several modifications were made for the 1972 model year Panteras. A new 4 Bolt Main Cleveland Engine, also 351 cu in, was used with lower compression ratio (from 11:1 to 8.6:1, chiefly to meet US emissions standards and run on lower octane standard fuel) but with more aggressive camshaft timing (in an effort to reclaim some of the power lost through the reduction in compression). Many other engine changes were made, including the use of a factory exhaust header.
The "Lusso" (luxury) Pantera L was also introduced, in August 1972 as a 1972½ model. It featured a large black single front bumper for the US market, rather than the separate bumperettes still used abroad, as well as a 248 hp (185 kW) Cleveland engine. During 1973 the dash was changed, going from two separate pods for the gauges to a unified unit with the dials angled towards the driver. The U.S. version 1974 Pantera GTS featured GTS badging but not the higher compression, solid lifter engine of its European GTS "cousin".
Ford ended their importation to the US in 1975, having sold around 5,500 cars. De Tomaso continued to build the car in ever-escalating forms of performance and luxury for almost two decades for sale in the rest of the world. A small number of Panteras was imported to the US by gray market importers in the 1980s, notably Panteramerica and AmeriSport. After 1974, Ford US discontinued the Cleveland 351 engine, but production continued in Australia until 1982. De Tomaso started sourcing their V8s from Australia once the American supplies dried up. These engines were tuned in Switzerland and were available with a range of outputs up to 360 PS (265 kW; 355 hp).
According to De Tomaso the chassis was completely revised in 1980, beginning with chassis number 9000. From May 1980 the lineup included the GT5, which had bonded and riveted-on fibreglass wheelarch extensions and from November 1984 the GT5S model which had blended arches and a distinctive wide-body look. The GT5 also incorporated better brakes, a more luxurious interior, much larger wheels and tires and the fiberglass body kit also included an air dam and side skirts. Production of the wide body GT5 (and similarly equipped narrow body GTS models) continued until 1985, when the GT5-S replaced the GT5. Although the factory has not made its records available, an analysis based on Vehicle Identification Numbers by the Pantera Owners Club of America (POCA) late model (9000 series) registrar has shown that fewer than 252 GT5 Panteras were likely to have been built. The GT5-S featured single piece flared steel fenders instead of the GT5's riveted-on fiberglass flares, and a smaller steel front air dam. The 'S' in the GT5-S name stood for "steel". Otherwise the GT5-S was largely identical to the GT5. The POCA 9000 series registrar's VIN analysis indicates that fewer than 183 GT5-S Panteras were built. Concurrent GTS production continued, on a custom order and very limited basis, until the late 1980s.
The car continued to use a Ford V8 engine, although in 1988, when the supply of Ford 351 Cleveland engines from Australia ran out, De Tomaso began installing Ford 351 Windsor engines in the Pantera instead. For 1990 the 351 was changed to the Ford 302 cu in (4942 cc, commonly called a "5.0"). Incorporating a Marcello Gandini facelift, suspension redesign, partial chassis redesign and the new, smaller engine, the Pantera 90 Si model was introduced in 1990. Only 38 90 Si models were sold before the Pantera was finally phased out in 1993 to make way for the radical, carbon-fibre-bodied Guarà. Some say 41 were built (with the last one not finished until 1996), of which four were targa models. The targas were converted by Pavesi directly off the production lines. In all, about 7,200 Panteras were built.
ALL the credit for the model goes to the respected author/authors. I did the mats/scene/rendering/post work. Love it or hate it, choice is yours.
