Nash 680

The Nash 680 was a six-cylinder car that the Nash Motors Company in Kenosha presented in 1918 as the first model of its own production and manufactured until 1921. The successor was the almost unchanged Nash Six (model 690), which was built until 1924.

Its chassis had wheelbases of 3,073 mm or 3,226 mm. The car had an overhead six-cylinder block engine with a displacement of 4,079 cm³ (bore × stroke = 82.6 mm × 127 mm) and an output of 55 bhp (40 kW) at 2,400 rpm. The engine power was passed on to a three-speed gearbox (with center shift) and then to the rear wheels via a single-disc dry clutch. The mechanical outer band brakes worked on the rear wheels.

There was a 2-door roadster, a 2-door coupe and a 4-door sedan, as well as a 4-door touring car with 5 or 7 seats.

In 1919 only more superstructures were added, but the technical features of the cars remained the same.

In 1922 the Nash Six (model 690) replaced the 680, but without any noticeable change. Only the cooler was a bit higher. From 1923 on, there were disc wheels instead of spoked wheels.

In 1925, the significantly revised Advanced Six and Special Six models replaced the 680/690 series.
