On July of 1955, the Chevrolet design studio staff create a dream car
for the 1956 GM Motorama shows, called Corvette Impala. The Corvette
grille and grille surround are incorporated, as well as other Corvette
components. This hardtop five-passenger sports sedan shows the name
"Corvette Impala" on the front emblem and rear license plate. On January
19 of 1956 the Motorama show opens in the Waldorf Astoria in New York
City, running for nine days. The 1956 Corvette makes its debut and the
Corvette Impala show car is displayed.
