The 1968 Chevrolet Corvette
"Corvette '68... all different all over". That's the quote from the sales brochure
for the redesigned 1968 Corvette. The body was completely redesigned with the coupe
losing it's fastback window but gaining a removable back window and removable t-tops
for that almost convertible feel. The chassis itself did not change much from the
1967 model. The new hidden wipers and hidden headlights are vacuum operated instead
of electrical. Door openers now use a push button to open and a push in handle to
pull the door, this was only used on the 1968 model. The new auxilliary top for
the convertible has a glass rear window. The new standard automatic was the 3-speed
Turbo Hydra-Matic instead of the 2-speed PowerGlide used previously. A new fiber-optic
monitoring system was added to the dash and "Astro-Ventilation" was added to improve
the airflow in the cabin. The '68 Vette did not have the "Sting Ray" badging on
it anywhere, it would return in '69 as "Stingray". 1968 was also the year that Zora
Arkus-Duntov was named Chief Engineer of the Corvette.
