Cadillac's famous corolla shield badge symbolizes its leading position in the automobile industry. This profound and exquisite symbol is also the symbol of Cadillac family as a royal aristocrat, and it also shows the courage and honor of the founder and ancestor of Detroit City. The corolla badge is taken from the badge used by Mr Cadillac. Although the Cadillac badge was not registered as a trademark until 196. But it has been used since September 192. In the early badge design, merlettes tilted to the left, and a garland consisting of tulip buds extended upward from both sides and met at the crown at the top.

from p>1916 to 1918, Cadillac logo was a tulip bud and a crown with nine pearls on the original registered trademark. The pearls in the crown later became seven and were designed on the shield. This design has been in use since 1925. In 1933, in order to better combine with Cadillac's flowing model, the designer made the logo grow long wings. After the war, Cadillac launched a new logo, including the basic "V" and corolla design. In 1947, the logo first combined the word "V" with the corolla. Since the 1956 model, the Cadillac logo has gradually become longer, lower and wider.

by 196, Cadillac models had the widest logo. In the new century, Cadillac has made a series of drastic innovations, including redesigning the logo of Cadillac Corolla Shield. The newly designed logo contains bold and sharp edges and corners, reflecting Cadillac's future design concept. The new corolla retains the existing color combination-golden and pure black, symbolizing wisdom and wealth; Red symbolizes courage in action; Silvery white represents purity, kindness, virtue and abundance; Blue represents the chivalrous spirit of chivalry. The logo is based on platinum color. This is the first time in twenty-seven years to make a big innovation in the logo, and it is also one of the thirty innovative designs of Cadillac in ninety-seven years.

In the history of more than 1 years from the trademark registration of Cadillac to today, Cadillac cars have been used by countless political circles, literary and art circles and corporate giants. Among these cars, fleetwood is regarded as the supreme, mostly used as a courtesy car, which represents the highest quality and image of luxury cars of General Motors. Cadillac has always been the symbol of the most luxurious car in America.
