The Fiat 850 (Tipo 100G^[1]) is a small rear-engine, rear-wheel-drive car manufactured and marketed by Italian car manufacturer Fiat from 1964 to 1973.

History

Overview

Its technical design was an evolution of the successful Fiat 600. The internal name for the Fiat 600 development project was "Project 100" and consequently, the internal Fiat codename for the 850 project was 100G (G was a follow on of model designations for the 600 which ran from A to F). The engine of the 850 was based on that of the Fiat 600, but had its capacity increased to 843 cc. The 850 came in two versions: "normale" (standard) with 34 hp (25 kW) and "super" with 37 hp (28 kW). The maximum speed was approximately 125 km/h (78 mph). While it was not a large step forward in technical development, it possessed a certain charm with its large rolling eyes and its short tail, in which the engine sat.

Variants

The 850 family included several body styles sharing core technical components:

• Fiat 850 Special — Revised version of the 850 sedan, launched in 1968. It shared the 47 hp (35 kW) engine of 850 Coupé, and offered front disc brakes, sport steering wheel and improved trim. With a 25 percent increase in power, plus disc brakes nestled behind 13" wheels, it was a "sport sedan" in the vein of the BMW 2002, albeit on a smaller scale.
• Fiat 850 Familiare — The Familiare was a boxier and slightly larger successor to the Fiat 600 Multipla. It featured space for seven passengers in three rows, suitable for groups including children and thin adults, buts too small to accommodate seven typical adults in comfort.

The 850 Familiare continued in production till 1976 long after the saloon version of the 850 had been replaced by the Fiat 127. In 1976 the Fiat 900T was introduced, retaining most of the body panels of the 850 Familiare, but featuring the 903 cc engine from the Fiat 127 (although, in this application, still mounted behind the rear axle): the 900T benefitted from significant enhancements in 1980, being now renamed 900E. At least in the UK the 900 series camper vans were badged as FIAT Amigo. Production finally ended in 1985.

• Fiat 850 Coupé — The Coupé was introduced for the first time 1965 on the Geneva Motor Show and had the original 843 cc (51 cu in) engine producing 47 hp (35 kW). The maximum speed at that time was 135 km/h (84 mph).
• Fiat 850 Spider — At the same time as the Coupé, Fiat also introduced the convertible sporty two-seater Spider, with the original 843 cc engine tuned to produce 49 hp (37 kW) which allowed it to reach a top speed of 145 km/h (90 mph). The body was designed and built by Bertone in its Grugliasco, Turin plant.^[7] The folding roof section made of fabric could be stowed away completely under a rear flap. The Bertone design also featured smooth, essential lines and simple yet elegant details, such as the recessed headlamps equipped with tilted plexiglass covers to follow the lines of the wings, and the dihedral side panels inspired by Bertone's 1963 Corvair Testudo.This engine ran counterclockwise, a unique feature compared to other engines.

At the time of their introduction into the United States the Sedan, Coupé, and Spider were marketed with a reduced capacity, high compression 817 cc (50 cu in) engine in order to beat US emissions regulations at the time which applied only to engines equal to or larger than 50 cubic inches. Compression was raised from 8.8:1 to 9.2:1, requiring premium octane fuel.

In order to separate the sportier variants Coupé and Spider from the basic version, apart from the increase of engine performance, the equipment was also extended and adapted to the higher expectations. Both received sport seats, a sport steering wheel and round speedometer; Spider even received a completely rearranged instrument panel. The front drum brakes were replaced with disc brakes, although drum brakes remained on the rear wheels.

In 1968, Fiat revised the successful Spider and Coupé again and gave them an even stronger engine with 903 cc and 52 hp (39 kW). They were called Sport Spider and Sport Coupé. The Sport Spider body stayed essentially the same, but with a restyled front. The headlamps were moved forward slightly and the glass covers were eliminated giving the car a "frog-eye" look, and the original flush front turn indicators were replaced with units hung below the bumper. Several limited special edition versions of the Spider were offered, including the Racer featuring a body-colored metal hard top and the Racer Berlinetta featuring a black vinyl hard top.

There was a minivan and transporter model as a successor of the world's first minivan, Fiat 600 Multipla, which was later renamed to 900T and likewise received the larger capacity of 903 cc.

Production of the Coupés ended in 1971, of the sedan in 1972, and of the Spiders in 1973, after altogether nearly 2.3 million models were sold worldwide, 140,000 of which were Spiders.^[7] Under the name SEAT 850, it was however further produced for some years in Spain, also in a four-door variant. As a successor the Fiat 127 was brought to the market in 1971 which combined the 903 cc push-rod OHV engine with the FIAT 128 transmission and suspension components in a fashionable fast- and later hatch-back 2-door sedan.

Between 1978 and 1983, the U.S. government issued a highly unusual recall for the Fiat 850—going back 10 years—for rust problems.^[8]

In 1967, Road & Track called the Fiat 850 coupé "one of the handsomest, best-balanced designs ever seen on a small car."^[8]

Non-Fiat derivatives

SEAT 850

Spanish manufacturer SEAT also built the 850 into the 1970s. They also offered a four-door saloon derivative in two different iterations. The Fiat 850 was also produced under the name Pirin-Fiat in Lovech, Bulgaria, on the basis of complete knock down (CKD) kits between 1967 and 1971.^[9]

Abarth

Fiat-Abarth OT 850

Fiat-Abarth OT 1000 Coupé

Fiat-Abarth OT 1300 Coupé

Fiat-Abarth OT 1600 Mostro

Fiat-Abarth OT 2000

Abarth produced several tuned versions of the Berlina, Coupé, and Spider, with ever increasing displacements. These belonged to the OT series of Abarth cars—standing for Omologata Turismo or "touring homologated", which also included two-seater sports racing cars.^[10]

• Fiat-Abarth OT 850 (model 101): Abarth's first 850 derivative, introduced in July 1964. Its Tipo 201 engine was the regular saloon's 847 cc inline-four brought from 34 PS (25 kW; 34 bhp) to 44 PS (32 kW; 43 bhp); top speed went up accordingly from 120 km/h (75 mph) to 130 km/h (81 mph).^[10] The OT 850 could be distinguished from the standard Fiat model by its Abarth badging, an asymmetric front ornament with the Abarth shield on the right hand side and the "Fiat Abarth" script on a red field on the left, and wheels with cooling slots. From October of the same year it became available in two guises: OT 850 Oltre 130 ("Over 130"), almost unchanged from the initial model, and OT 850 Oltre 150, with a 53 PS (39 kW; 52 bhp) engine, front disc brakes and a 150 km/h (93 mph) top speed.^[10]
• Fiat-Abarth OT 1000: introduced in October 1964. Engine displacement increased to 982 cc, it produced 61 PS (45 kW; 60 bhp) and 79 N·m (58 lb·ft) of torque.^[10] Front brakes were changed to disks.
• Fiat-Abarth OT 1000 Coupé and Spider: introduced in October 1965. Compared with the saloon version, the engine was a more powerful Tipo 202 producing 62 PS (46 kW; 61 bhp)^[10] and 79 N·m (58 lb·ft) of torque. Top speed was 155 km/h (96 mph) for the coupé and 160 km/h (99 mph) for the spider.^[10] The coupé was facelifted in November 1968 concurrently with the regular Fiat 850 Coupé, receiving a full-width grille and twin round tail lamps.
• Fiat-Abarth OTR 1000: launched alongside the OT 1000 Coupé, and based on the 850 Coupé bodyshell as well. Its type 200 engine had an all-new Abarth-designed cylinder head with valves arrnaged in a V instead of parallel—hence the R in the name, standing for Radiale, radial.^[10] The combustion chambers were shaped as two spherical caps, one around each valve; there was a inlet duct per cylinder, each fed by one choke of the two twin Solex carburettors.^[10] Abarth claimed an output of 74 PS (54 kW; 73 bhp) at 6,500 rpm and a top speed of 172 km/h (107 mph) for the road version.^[10] The OTR was set apart from the OT 1000 Coupé by a rectangular front grille bearing the Abarth badge, needed for the front mounted radiator.

At the 1965 Turin Motor Show Bertone showed on its stand an one-off OTR 1000 berlinetta, based on the 850 Spider but with a fixed roof and a front radiator opening.^[10] Suffering the competition of less expensive and less complex OT models, production of the OTR 1000 ended with the arrival of the restyled 850 Coupé in 1968.^[10]

• Fiat-Abarth OTS 1000: introduced in April 1966. OTR 1000 bodyshell, but standard head OT 1000 engine with output upped to 68 PS (50 kW; 67 bhp) and top speed to 160 km/h (99 mph).^[10] FIA homologated it in the GT class in 1966. Abarth later developed several modifications, including a new inlet manifold for two twin-choke Solex carburettors. This gave birth to the OTSS 1000 or OT 1000 SS. Both OTS and OTSS were restyled in November 1968 like the OT 1000.
• Fiat-Abarth OT 1300: November 1966 launch. Visually identical to the OTR 1000 save for the widened wheels, it used a Fiat 124-derived engine displacing 1,280 cc.^[10] Engine power was 74 PS (54 kW; 73 bhp) and top speed 172 km/h (107 mph), both the same as on the OTR 1000, but thanks to the simpler engine the car was cheaper.^[10] Restyled in 1968 together with the 1.0-litre OTs.
• Fiat-Abarth OT 1600 Mostro (model 136/C): extreme variant based on the 850 saloon body, unveiled at the October 1964 Turin Motor Show and nicknamed Mostro, monster. It was fitted with a Tipo 236 1,592 cc twin cam, twin spark engine from the Fiat-Abarth 1600 Sport racing car.^[10] The 1.6-litre put out 155 PS (114 kW; 153 bhp) and top speed was 220 km/h (137 mph).^[10] The rear wings were greatly enlarged to clear wide rear alloy wheels.
• Fiat-Abarth OT 2000: introduced in February 1966, it was based on the 850 Coupé but powered by a two-litre engine.^[11] It differed visually from the 850 Coupé in having a barred grill between the headlights, a split front bumper flanking a spare wheel which projected forward below the grille,^[11] widened front and rear tracks and wings, and a vented front bonnet. The 1,946 cc twin cam four-cylinder produced 185 PS (136 kW; 182 bhp) and could propel the car to 240 km/h (149 mph).^[10] Three examples were produced.^[12]

Francis Lombardi Grand Prix

Francis Lombardi Grand Prix

Italian coachbuilder designed and built a small sports car with fastback coupé body based on the 850, the 1968 Francis Lombardi Grand Prix. The car was also marketed by OTAS as the OTAS 820, equipped with Giannini engines, and in an Abarth version, the Abarth Scorpione.

Michelotti Shellette

1969 Michelotti Shellette

The Michelotti Shellette was a beach car based on the 850, styled and built by Giovanni Michelotti. Designed in the mould of Ghia's 500 and 600-based "Jolly", it was a more useful proposition, being faster and better equipped. Only about 80 were built, with some of the early ones using DAF underpinnings. The Shellette had the more powerful 47 PS (35 kW) engine of the Special/Coupé.^[13]

Siata Spring

Siata Spring

The Siata Spring was a 2-seater roadster built by Siata on the basis of the 850. Introduced in 1967, it featured retro styling with a mock upright radiator grille, separate wings and headlights, and running boards.^[14] In Italy it was initially priced at 795,000 Lire, 255 thousand Lire cheaper than Fiat's Bertone 850 Spider.^[15] Top speed was 125 km/h (78 mph).
