"Z"

Dad,
What does the "Z" stand for?

ZR1, Z06, Z51, Z71, Z28, Z24

I think there is more... But I think the ZR1 is the only 2 letter 1 digit
Z...

Special package and performance option package code. Not always the
case but most of the time, once it was a package code for the Indy
Pace car Z4Z. Then there was the Z16 that was used for a half baked
stripe package for a collector designation for the C5 and used for the
Z15 option for the C4 Grand sport in '96. Z07 for an adjustable
suspension and full blown race package. Z6A for rear mirror and back
glass defogger. ZN1 for a trailer package, ZQ2 and ZX2 which were
convenience group codes.

It all boils down to the powers that be at GM saw that the letter and
numbered packages badged on the cars/trucks sold, sort of why we now
have C4, C5, and C6 instead of the old solid axle, mid year and so on
as a identifier.

Believe it or not, that was what I was going to suggest.

I wonder what Z6A for rear mirror and back glass defogger had to do
with Zora or what he had to do with the off road package for the
pickups? If they were using the letters to honor/indicate someone ,
who do you suppose the 'U' packages were in reference to?

Options/packages were numbered in the beginning, 2 digits, then 3,
then 3 with a letter suffix, then 4, then 4 with a letter suffix, and
in 1963 they went to a letter prefix and a number, A01. As you can see
this was using up number/letter combinations as the number of options
multiplied as GM entire fleet require option numbers. The letters used
for options you could order included A, C, J, L, M, N, P, T, U, and
the now famous Z06. Remember they were stamping these in sheet metal
tags so any letter that could be confused with a number was omitted
such as the B, S, and I, which limited the combinations. The Z with
its sharp corners seldom is confused with a 5 or an S so it was used
to retain as many letter number combination as possible.

It is still possible that in the case of the Z06 it was applied as the
roomer suggests but in the real world of manufacturing most likely
not. Why was it not applied as M06 as Mitchell was behind the '63
design?

From what I can find on the 'net. For 1963 there was a major overhaul
of the RPO codes. They used the alphabet to try and categorize them with
Z being the last letter and being assigned packages for instance the
first one
Z01 : COMFORT AND CONVIENCE GROUP resulted in this option for
windshield washers being "renamed"

1961-1964 U.S.

In 1961, a factory-installed bottle, 3789848, and its bracket were
introduced as part of the Comfort and Convenience group, RPO 120. The
RPO was changed to Z01 in 1963. This label was black and white and very
similar to 988299.

So, I suspect that "Zora" starting with "Z" is mere coincidence.

Z is the package RPO codes.

L is the engine RPO codes.

M is the transmission RPO codes. C for heating, cooling, and ventilation; N
for steering; P for tires and wheels, U for instrumentation (radios
usually).

And so on.

Z11 was the NASCAR full size Chevy.
http://www.conceptcarz.com/vehicle/z9077/default.aspx

Z16 was the big block option package in the Chevelle in 1965.

Z28 was the Special performance (Trans Am) package 1967 Camaro, which
followed the Z21 Style package, the Z22 Rally Sport package, Z23 Special
Interior, and Z87 Custom Interior.

ZL1 was the aluminum engine package Corvette in 1969, although it was not
much of a package really. It was closer to simply engine option, but what
it did was install the aluminum block "package" on the L88 engine OPTION.

In 1970, then there was the ZR1 option and in '71 the ZR2 option was added.
The ZR1 was a race package with the LT1 engine and the ZR2 was the same
package with the LS6, although planned for '71 with the LS7.

The Z packages were a package because they included a number of options.
Frequently the package also REQUIRED options to be ordered. The very well
known Z28 included the 302 engine, special suspension, special mufflers on
dual exhaust, special wheels (15x6 Rally), heavy duty radiator, and more.
It also required special four speed, power disc brakes, and more.

Z package codes were much more common in other Chevy lines than Corvette in
the early years, so the few Z packages on Corvettes were assumed to be
something really special in the meaning of the name, but in reality, they
were just numbers - ones that were available or already in use for the same
item in another line

The "Z means Zora" and the "ZR means Zora's Racers" are myths.
