Like other competition models from Abarth, the 1000 SP of Sport Prototype complied with the rule created by the innovative Carlo Abarth, who has always preferred light and agile competition machines, which have been miracles with small engines, in addition to being less powerful, inexpensive. The Abarth 1000 SP is designed in the form of Barchetta Opened, it weighed only 480 kg, which allowed him to achieve real miracles with an engine with a power of 105 hp.
Abarth hired engineer Mario Colucci to design the 1000 SP in 1966, but unlike Carlo Abarth, the president, Colucci didn’t believe in prototypes designed exclusively for competition with front or rear engines. and then Barchetta Mount the engine / gearbox assembly in a central position, directly behind the pilot, for better mass distribution across the two axles.
The tubular structure and the light open body contributed to a weight of less than half a ton, allowing Abarth to continue assembling its usual two-spoke, four-cylinder engine with two overhead camshafts, powered by two Weber 40 cc twin carburetors, this unit is the same that powers the Abarth 1000 TC. Which, in turn, is derived from the Fiat 600D.
The Abarth 1000 SP was swift and fast, reaching 220 km / h, and its value was immediately evident with the victory in the Nürburgring 500 km of 1966, in the class up to 1000 cc, which would be followed by successes in contested racing traditional circuits and even downhill tests.
To honor the historic Abarth 1000 SP, Centro Stile Fiat and Abarth decided to build a modernized version of the 1966 1000 SP. The base is a carbon-fiber chassis in the Alfa Romeo 4C Spider, which, although not tubular, is light and definitely stiffer, while maintaining the center engine and rear wheels. Barchetta A native. The body tries to respect the original version as closely as possible, although the new model is much larger and more massive.
The engine used is a four-cylinder engine with a 1742 cc SuperCharged, which delivers 240 hp, mated to an automatic gearbox with a dual-clutch and a six-speed. At roughly twice the weight and more than twice the strength, the new 1,000 SP should be faster than the original.
According to the constructor, only one unit will be manufactured, which has no profession in competition, and should be limited to exhibitions and demo sessions.
