The Kessler Motor Company was a short-lived American manufacturer of aircraft engines and automobiles.

The first model, the Kessler Super-Charge Four, was announced in January 1920 and shown the following month at the Detroit Auto Show.

It was innovative in incorporating a compression space into the crankcase; pressure was increased by the downward movement of the pistons.

[3] A more than respectable performance of 70 bhp (52.2 kW) was claimed, equalling that of the basic model of the Bugatti Type 35.

Because of the company's limited resources, it was an assembled car, consisting of purchased components fitted together.

[1] A new production location was rented, the former facilities of Liberty Motor Car in Detroit.

The Kess-Line 8 was also extremely reminiscent of a competitor: the engine hood and radiator grille very closely resembled those of the much more expensive Lincoln L.[4][8] However, the Kess-Line, again available only as a touring car, had sportier lines than the massive Lincoln and "helmet" fenders—close to the wheel and turned out at the base, so that the profile recalled a Classical helmet.

The engine was an inline V8 offering 100 bhp (75 kW); a performance exceeded by very few production automobiles at the time, such as the compressor version of the Bugatti Type 35 or the Mercedes 24/100/140 PS.
