Dino 206 S

The V6

The 65-degree V6 was mounted longitudinally in the rear of the car and displaced 1986.60 cm³ from an 86 by 57 mm bore and stroke. The first variant, Tipo 227L, had two valves per cylinder, while the later Tipo 231 and 231B received experimental three-valve heads; all had twin overhead camshafts per bank. The combustion chamber design was derived directly from Formula 1 experience, with compression between 10.8 and 11:1. Most engines were fitted with three Weber 40DCN15 carburetors, while some had Lucas fuel injection. Lubrication was by dry sump.

Chassis and body

The Tipo 585 chassis was a welded tubular frame with independent suspension all around. The 2280 mm wheelbase was identical to both predecessors, disc brakes were fitted at all four corners, and the fuel tank held 100 liters. The five-speed gearbox had no synchromesh. The body was built by Piero Drogo's Carrozzeria Sports Cars. Most examples were Spyders with a roll bar behind the driver; only three were built as closed Berlinettas from the outset, and several later received open Barchetta bodywork.

Racing and homologation

The 206 S made its racing debut at the 1966 12 Hours of Sebring, where Ludovico Scarfiotti and Lorenzo Bandini finished fifth overall. Ferrari aimed to build at least 50 units for Group 4; the Porsche 906 had already been homologated in May 1966. In the prototype class, the Dino faced the improved 906 and the 910, yet still won three races in the 2.0-liter class. Ferrari finished second in the manufacturers' championship for the under-2000 cm³ class.
