[PTA Slowchat] Lancia Fulvia V4 1231 cc

De OP
Lancia Fulvia Berlina GT
V4 1231 CC

The Fulvia was designed by Antonio Fessia to replace the Lancia Appia, with which it shared some 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 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 solid axle with a panhard rod and more leaf springs was used in back. Four wheel Dunlop disc brakes were a welcome novelty, though Road & Track still noted some significant brake fade.


Engine
One element that was new was the narrow-angle V4 engine. Designed by Zaccone Mina, it used a narrow angle (12°53'28") and was mounted well forward at a 45° angle. The engine is a DOHC design with a one camshaft operating all intake valves and another operating all exhaust valves. It is unique in that though a vee configuration, the very narrow angle of the cylinders allowed for use of a single cylinder head.

Displacement began at just 1091 cc with 59 hp (44 kW) with a 72 mm bore and 67 mm stroke. A higher (9.0:1) compression ratio raised power to 71 hp (53 kW) soon after.

The engine was bored to 6 mm to enlarge displacement to 1216 cc for the HF model. This, and some tuning, raised output to 80 to 88 hp (60 to 66 kW).

The engine was reengineered with a slightly narrower bank angle (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 latter engine is most common, with the former only sold in Greece. The American-spec 1.3 L produced 87 hp (65 kW) and was described as "highly tuned" by Road & Track at the time.

The engine was redone again for a new HF with an even-narrower angle (11°20' now) and longer 75 mm stroke for its final incarnation. A bore of 82 mm gave it a displacement of 1584 cc, and power shot up to 114 to 132 hp (85 to 98 kW) depending on tune.
