REO's two most memorable cars were its Reo Flying Cloud introduced in 1927 and the Reo Royale 8 of 1931. The
Flying Cloud was the first car to use Lockheed's new hydraulic internal expanding brake system and featured styling by Fabio Segardi. While
Ned Jordan is credited with changing the way advertising was written with his "Somewhere West of Laramie" ads for his
Jordan Playboy, Reo's Flying Cloud—a name that provoked evocative images of speed and lightness—changed the way automobiles would be named in the future. It had a wheelbase. The final REO model of 1936 was a Flying Cloud. The 1931 Reo
Royale was a trendsetting design, introducing design elements that were a precedent for true automotive
streamlining in the American market. The 8-cylinder model was sold through 1933 with minor updates. The name was used on a lower-priced 6-cylinder model through 1935.
Beverly Rae Kimes, editor of the
Standard Catalog of American Cars, terms the Royale "the most fabulous Reo of all". In addition to its
coachwork by Murray designed by their
Amos Northup, the Royale also provided buyers with a
straight-eight with a nine-bearing crankshaft, one-shot lubrication, and thermostatically-controlled radiator shutters. The Royale rode upon factory wheelbases of (Model 8-31) and (Model 8-35); a 1932 custom version rode upon a wheelbase (Model 8-52). As many as 3 Dietrich
coachbuilt bodies were built on wheelbases in 1931. Beginning in 1933, the Royale also featured as an option REO's
semi-automatic transmission, the Self-Shifter. This unit was unreliable, and
Consumers Union Reports advised readers to avoid it. The Model 8-31 was priced at $2,145. The model 8-35 was priced from $2,745 for the sedan to $3,000 for the
convertible coupe. The coachbuilt cars were priced close to $6,000. A convertible Victoria was listed at $3,195 but only one is known to have been built. The 8-35 & 8-52 are considered full
