[1] Crane-Simplex Company was formed in 1922 in Long Island City, New York, by Henry M. Crane to resume production of the luxury car.

[2][3] Organized on September 20, 1922, Henry M. Crane announced the Crane-Simplex Company with the Long Island City, Queens, New York plant and assets being purchased from Mercer Motors, Inc., "with plans to revive his masterpiece"[4] Capitalized at $500,000, company offices were located at the United States Realty Building at 115 Broadway, with L. R. Ayers as President.

[11] In July 1922 Henry M. Crane became a consulting engineer and technical assistant to Alfred P. Sloan of General Motors.

[17] In the August 1916 Automobile Topics magazine 2- page article, the new cars was described as the "Model 5 Simplex-Crane -- or plain Simplex".

[19] This was achieved with a new design for springs that reduced lateral shock when a wheel went into a pothole or if the driver took a curve at a high speed.

[20] At the time, a newspaper reported, "The six-cylinder power plant on which the Crane-Simplex Company has established its reputation for mechanical excellence, is the result of H. M. Crane's engineering genius.

[23][16] Production was limited to 300 cars per year, the maximum output of the company's 800 employees who worked in three shifts, day and night.

[21] "The car had to be right or Mr. Crane would not send it out," according to Walter B. Reynolds who was chief of the final road testing department for Simplex-Crane.

[23][16][25][20] The Model 5 chassis included a complete dashboard with instrumentation, front fenders, trimmed running boards, Goodrich Silvertown cord tires, an electric horn, headlamps, a reel-mounted trouble lamp, taillamp, a jack, and tools.

[19] Based on the company's catalog, customers could choose between a limousine, landaulette-limousine, touring landaulette, and enclosed bodied coach to add to their chassis.

"[24] However, it did have a market; as Horseless Age magazine wrote in its review of the Simplex-Crane Model 5, "There are always people who want only the very best and are willing to pay a good price for what to the ordinary purchaser may seem minor advantages.

[33] Car production at New Brunswick ceased in October 1917 as Wright began making airplane engines for World War I.

[2][3][36] In July 1921, Hare's motors announced it would be dissolved and the separate units would reorganize as individual companies.
