The Lancia Fulvia (Tipo 818) is an automobile produced by Lancia between 1963 and 1976. Named after Via Fulvia, the Roman road leading from Tortona to Turin, it was introduced at the Geneva Motor Show in 1963 and manufactured in three variants: Berlina 4-door saloon, 2-door Coupé, and Sport, an alternative fastback coupé designed and built by Zagato on the Coupé floorpan.
Fulvias are noted for their role in motorsport history, including a 1972 win of the International Rally Championship. Road & Track described the Fulvia as "a precision motorcar, an engineering tour de force".
Specifications
Chassis
The Fulvia Berlina was designed by Antonio Fessia, to replace the Lancia Appia with which it shared almost no components. The Appia was a rear wheel drive car, however, while the Fulvia moved to front wheel drive like the Flavia. The general engineering design of the Fulvia was identical to that of the Flavia with the major exception of the engine, the Flavia having a four-cylinder horizontally opposed engine and the Fulvia a 'Narrow Angle' vee configuration as featured on most production Lancias from the Lambda. The Fulvia used a longitudinal engine mounted in front of its transaxle. An independent suspension in front used wishbones and a single leaf spring, while a beam axle with a panhard rod and leaf springs was used in back. Four wheel Dunlop disc brakes were fitted to first series Fulvias. With the introduction of the second series in 1970 the brakes were uprated with larger Girling calipers all round and a brake servo. The handbrake design was also changed - using separate drums and brake-shoes operating on the rear wheels.
Engine
The Fulvia's narrow-angle DOHC Lancia V4 engine was mounted well forward at a 45° angle. A new design, by Zaccone Mina, its unusually narrow 12° V allowed a single cylinder head to cover all the cylinders, with one cam each for intake and exhaust valves.
Displacement started out at just 1091 cc, with a 72 mm bore and 67 mm stroke. Fitted with a single carburettor it produces . A higher (9.0:1) compression ratio and twin Solex carburettors raised power to soon after.
The engine was bored to 76 mm for the 1216 ccHF model. With additional tuning output was raised from .
The engine was re-engineered with a slightly narrower bank angle (from 12°53'28" down to 12°45'28") and longer (69.7 mm) stroke for 1967. Three displacements were produced: 1199 cc (74 mm bore), 1231 cc (75 mm bore), and 1298 cc (77 mm bore). The new 1298 cc engine was produced in two versions; the type 818.302 produced at 6000 rpm and was fitted to first series Coupés, Sports and Berlina GTE and later to the second Series Berlina. The Type 818.303 was first produced with and was fitted to the first series Coupé Rallye S and Sport S. For the second Series Coupé and Sport power was slightly reduced to at 6000 rpm. The 1199 cc engine was only fitted to the Berlina sold in Greece.
The engine was completely reworked for the new 1.6 HF with an even-narrower angle (now 11°20') and longer 75 mm stroke combined with a bore of 82 mm gave it a displacement of 1584 cc, and power ranged from depending on tune.
