Summer 2006 Forward to a Friend



Subaru FF-1
The features of the 1971 Subaru FF-1 foreshadowed some of today’s Subaru equipment.

FF-1

The attic’s FF-1 is a 1971 model, featuring front-wheel drive and a 1,100-cc (66.4 cu. in.) horizontally opposed, four-stroke, four-cylinder engine. The carbureted engine produced 62 horsepower. With the FF-1, Subaru took a giant step toward today’s Subaru technology.

The Subaru FF-1 was an innovative automobile for the early 1970s. It had a long list of features that were unique or foreshadowed the types of equipment that are typical on today’s vehicles. Besides front-wheel drive, the FF-1’s chassis systems included rack-and-pinion steering, independent front and rear suspensions with torsion-bars and front drum brakes mounted inboard. The inboard mounting took weight off the wheels, allowing the tires to make better contact with rough roads for improved stability and control.

Also unique was the dual-radiator design of the engine cooling system. A smaller sub-radiator was used to help the engine warm up quicker when it was first started.
