The first ultra-luxury roadster model from Cadillac is called the Allante; this model was in the market from 1987 till1993. The name is pronounced "ah-lon-tay". The Allante was designed to compete with Mercedes-Benz SL and was called as “Callisto”. Allante's used the 4.1 litre V8 engine that was used by most of the other Cadillac models as well. Pininfarina of Italy designed and built the body of Allante and was shipped in specially-equipped Boeing 747s, 56 at a time, to Cadillac's assembly plant in Hamtramck, Michigan. As a result of this long process Allante also got few nick names like, "The Flying Italian Cadillac" and "the world's longest assembly line." 21,000 cars were built in the 17 years of this model.
Reasons for the failure of Allante: The price of the Allante, US,000 was higher than the other Cadillac models. Currently, Cadillac XLR-V at 0,000 is the most expensive Cadillac product. Although most of Allante's competitors were rear-wheel drive, Allante used the unique front-wheel drive (FWD) powertrain. FWD was not favoured for high-priced sports and touring cars, as the configuration's frequent tendency toward understeer under heavy cornering, torque steer under heavy acceleration, and a poor front-rear weight balance is not desirable. Many car magazines and auto enthusiasts stated that no sports car should have been FWD. The poor power-to-weight ratio in the early years also made the car perform badly. Hence Allante created the image of not a successful or reliable model and had to stop in 1993
