C on the start of the 1960s, Fiat raised the need for [1.99901 million] a new car that was located above the Fiat 600 and Fiat below 1100 . Although the initial idea was to create a brand new product, the economic difficulties facing the company at that time did not allow it and finally was born 850 [1.99901 million] a derivative of 600 .
The Fiat 850 was born in the mid-1960s to be between 600 and 1100.
Dante Giacosa , who also designed the 600, was commissioned to design the 850 based platform and a host of structural and mechanical elements 600, achieving a product of [1.99901 million] appearance more sophisticated .
A few months after the arrival on the market of the Fiat 850 sedan, the [1.99901 million] Geneva Motor Show was the venue chosen by the Italian house for the debut of the 850 versions [1.99901 million] Coupe and Spider.
The designer Dante Giacosa instructed to keep the platform and much of the mechanics that were used in the sedan, so the design modifications carried out by the [1.99901 million] Centro Stile Fiat could not be too drastic. However, the team led by Mario Boano managed to achieve sports sober and balanced , with space for four occupants and cargo space with sufficient capacity.
The interior was sophisticated, with a competition instrument panel type, equipped with two large master clocks wood trim on the panel , sport steering wheel and seats with good grip.
In addition to offering improved mechanical level, revised brakes and steering, upgraded with a drive Weber dual carburetor body , a brushless escape with four separate tubes and a power that was located in the 47 horsepower sufficient to enable it to achieve the 140 mph top speed.
The relationship between Fiat and Abarth was well established by then. It was almost the end of the 1960s and Abarth had already carried out several projects based on the Fiat 600. Based on the 850 Coupe Abarth made a special series that he called OTR 1000, equipped with a special engine with ‘radial head’ with a displacement reaching almost 1.0 liter displacement and power [1.99901 million] 74 horsepower .
Abarth led to almost 1.0 liter engine and gave a power of 74 hp, enough to reach 180 km / h.
The acronym OTR represented Omologato Tourism Radiale because as usual it was a product intended for the competition, in this case for the [1.99901 million] Gruppo 3 FIA , a company born in 1957 which forced the builders to approve 500 units per year to participate category.
The engine of the Abarth 1000 OTR was [1.99901 million] a block of 4 cylinders with 982 cubic centimeters of displacement equipped with two Weber carburetors two mouths and a power of 74 horsepower at 6,500 rpm, enough to achieved a top speed around 180 kilometers per hour and an acceleration of 0-100 km / h close to 10 seconds.
The engine was associated with a 4-speed manual transmission, while the front brakes were disc and rear drum. Had independent suspension planes transverse springs on the front axle and coil springs with wishbones on the rear axle, telescopic hydraulic shock absorbers double action stabilizer bars on both axes.
The OTR 2000 stood at 185 hp and could reach 240 km / h top speed.
A little later, Abarth 1000 OTR engine modified to meet new requirements for the approval of the FIA, taking its power to [1.99901 million] 80 horsepower at 7400 rpm , achieving a top speed that reached 190 kilometers per hour .
The OTR was designed to try and beat on track to [1.99901 million] Mini Cooper and [1.99901 million] Porsche, as also ran in the 911 Touring categories. The maximum development of 982 cc engine was used in the Abarth 1000 TCR Group 2 based on the Fiat 600, with a yield of [1.99901 million] 112 horsepower.
But the most spectacular came some time later, when Abarth launched the OTR 1300 and a bit later than [1.99901 million] OTR 2000 equipped with engine Bialbero of 2.0L and power [1.99901 million] 185 horsepower at 7,200 rpm mated to a five-speed manual transmission. These units manage to reach 240 kilometers per hour , with its only [1.99901 million] 589 kilograms .
Abarth made many great follies, but his adventure ended in 1971 when the company he founded was held by Fiat, leaving a legacy of 22 years of small, amazing motors.
