In the title....1970 Saab 96
It's equipped with a very rare feature called "Free Wheel"
The Saab 96 is an automobile made by Saab. It was introduced in 1960 and was produced until January 1980. Like the 93 it replaced, the 96 was a development from the old Saab 92 chassis and, on account of its improvements and modernisation, it opened new markets for the company. It was the car for which the marque Saab became internationally known, not least because of its safety innovations[clarification needed] and its motor sport successes. It was the first Saab model officially imported to the UK.
Throughout its life span, the Saab 96 and its station wagon sibling, the Saab 95, had the gear lever mounted on the steering column. This became an increasing rarity in the auto industry during the 1960s and '70s, but was an appreciated feature among rally drivers who could change gears faster than with a floor-mounted lever.
The gearbox originally had three gears, the first unsynchronised. Later, a four-speed option, with synchromesh first gear, was offered and the three-speed was phased out.
An unusual feature of the Saab drivetrain was a 'freewheel' or over-run clutch. This allowed the transmission to run faster than the engine, such as when decelerating, or descending a long hill. Although such freewheels had been provided in other cars before as an economy measure,[2] they were required in the Saab because of the limited lubrication in the two-stroke engine. A petroil-lubricated two-stroke requires lubrication according to its speed, but provides this lubrication according to the amount of its throttle opening. Where the engine operates at high RPM and low throttle (such as when coasting down a long hill), the lubrication provided may be inadequate. With the freewheel, a coasting engine could reduce its speed to idling, thus requiring only the small lubrication available from the closed, coasting, throttle. In certain higher-performance models and in later two-stroke models, direct injection of oil into the engine from a separate reservoir allowed lubrication to be a function of engine RPM and rendered mixing of oil with gasoline unnecessary.[citation needed]
Freewheeling was retained in the four-stroke variant, until the end of production. A minor drawback to the freewheel, particularly for drivers unfamiliar with the Saab, is that it makes engine braking unavailable except when, in later models, it could be manually engaged or disengaged by a control in the footwell.[citation needed]
