                                    HISTORICAL NOTES:                                       


The Imperial for 1931 was designated the CG series and is considered by many as the most beautiful Imperial ever built.  A new design, based on the 1929 L-29 Cord, was the biggest change in 1931.  Also, Chrysler narrowed engine production and the Imperial now came with the new corporate work-horse, the Flathead Eight.   In most Imperial advertising of this year, Imperial is now referred to as the Imperial "8", in reference to the new engine.  It also saw the introduction of new wire wheels for the Chrysler Imperial and this became the standard wheel treatment until the 40's.


Stock car driver Harry Hartz set numerous speed records with an Imperial sedan at Daytona Beach, Florida.  Another notable Imperial owner was Mayor Al Smith, of New York City, who drove an Imperial LeBaron Phaeton .
