double the output of the Buda CS6 in the K. In addition to the taxicab sedans, the Model M was available with a "utility" station wagon body as the MU6 in 1931 and 1932. Wealthy businessman Samuel Insull ordered a custom bulletproof M limousine, but was tried for fraud one year after he took delivery; it is not known what happened to his car. Model T (1933) Despite the losses of 1932 and using minimal funds, Checker was able to introduce a new taxicab for 1933, the Model T, derived from the Model M. The new taxicab utilized the new Lycoming GU or GUC straight-eight cylinder engine; Lycoming was part of the Auburn-Cord-Duesenberg (A-C-D) group owned by E.L. Cord, who also had recently assumed ownership of Checker. In 1933 Checker would also produce a brand-engineered version of the Model T, the Auburn Safe-T-Cab for A-C-D, which was sold in limited numbers to the Safe-T-Cab Company in Cleveland. Like the Model M, the Model T also was offered in a "Suburban Utility" variant for 1933 and 1934. In addition, approximately 500 Model T trucks were built in 1933. Model Y (1934) In 1934, Checker began development of a new taxicab, the Model Y. It was the third offering in the evolution of the 1928 Model K and quite striking in appearance, with many style cues reminiscent of its new corporate cousin, the Auburn, albeit an industrial version. Cord continued his method of marketing through up-to-date style and a sense of luxury, adding chrome trim, flared fenders, padded tops and vacuum-powered sunroofs. The Model Y also served as a platform for many new Checker concepts to be utilized for the next 50 years. The long wheelbase version could be purchased in 6- and 8-door variations and also offered an integrated body trunk, a first in the automotive industry. This configuration yielded the first mass-produced car with a three box design, years ahead of the 1947 Studebaker and 1949 Ford post-war offerings. Other features included a multi-position adjustable driver seat and glass windows in the roof that passengers would love when sightseeing in major cities. Looks alone were not the only similarities to Auburn; the Model Y utilized the Lycoming 148 hp inline GFD 8, the same engine used in the Auburn 850, although later in 1936 there was the option of a six-cylinder Continental engine. This taxicab would be produced until 1939.
