Why it matters

The CG Imperial of 1931 was Chrysler's first Imperial with the straight-eight and is considered by many the most beautiful Imperial. The LeBaron-bodied cars were its most remarkable styling, and only 339 custom and semi-custom CGs were sold, which conceptcarz notes made them rarer than the Duesenberg J and SJ.

02Production & history

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The CG replaced the Imperial with the 92 hp flathead six used since 1927, bringing the new 385 cubic-inch straight-eight (125 hp) and a four-speed transmission. Al Leamy was hired to style the CG Imperial, borrowing from the Cord L29, and LeBaron then improved it with a swept-back grille, a more elegant body-side treatment and a longer hood. The list price was $3,575.

Sales were low in the Depression, and the CG ran to 1933 with smaller semi-custom and custom sales before the Airflow Imperial replaced it in 1934.
