1966 Canadian Corvair production statistics

This article was published in the June, 2000 CORSA Communique.

Several years ago, Dave Newell obtained copies of GM of Canada's end-of-model-year production report for 1966. Dave shared this information with Bob Gilbert, who shared it with me. The report is chock full of interesting production statistics. The original document features one page of summary statistics plus 11 pages of details, organized by option and model.

Below are the summary statistics, followed by the details.

Summary statistics

The production figures Dave and Bob provided (hereafter referred to as "GM Canada's figures") are on a one-page report titled "1966 Corvair Manufacturing Schedule". The report is dated August 8, 1966. In the report, production is broken into three groups:

Production summary

As a side note, the production figures on the summary sheet that GM Canada's archives provides for interested owners is the "number produced for sale in Canada". So, for example, the summary sheet for my Corsa convertible shows it to be 1 of 192, not 211, built.

A few facts about SUPs and CKDs

From the article "Foreign Intrigue" in Dave's The (in)Compleat Corvair Story, I learned that Corvairs were actively sold in Belgium, Canada, Denmark, England, Germany, Mexico, Norway, South Africa, Sweden, Switzerland, Venezuela, and many other countries over the years. A total of 34,875 Corvairs were exported (approximately 23,000 SUPs and 11,500 CKDs).

When thinking about SUPs vs. CKDs, you might ask yourself, "Why would GM go to all the trouble of shipping a bunch of parts overseas for final assembly?" Some of the countries listed above placed prohibitive import duties on fully-assembled vehicles. Dave commented to me recently: "After 1962, Brazil, Peru, Venezuela, and Mexico, in particular, had such high tariffs that only the very rich could import complete cars. Another reason was shipping costs: shipping rates for automobile parts are less than for complete cars. Parts can be shipped much more compactly than complete cars, which take up more valuable floor space on ships. Their crates are stackable too. Most SUP cars were shipped uncrated."

To get around these problems, GM produced CKD cars in the U.S. and Canada and shipped them overseas, where they were assembled then sold.

From Dave's article and conversations with him, I learned that:

The story of SUP Corvairs is a little different. Unlike CKDs, they were produced in quantity both in the U.S. and in Canada during 1965 & 1966. Before 1965, fewer than ten SUPs left Oshawa each year. All the other SUPs came from U.S. plants.

When choosing from where to source a SUP for export, GM considered both:

For example, read about a 1966 Willow Run Monza coupe SUP that was very likely ordered by an American soldier stationed in Germany who had the car shipped back to the States after his service ended.

Dave added, "SUPs were exported for the 1967-69 model years from the U.S. because they were only built in the U.S., not Canada. However, you could consider a Swiss-built 1967 Corvair a SUP if it were exported to Italy, for example; or a Belgian-built 1967 Corvair a SUP if it were exported to Germany, for example. After 1967, production ceased in Belgium and in Switzerland although a very few SUPs were imported by both countries."

Swiss CKD notes

Dave's article notes that 144 CKD units were produced for Switzerland during model year 1966 and that 96 of them were sedans with manual transmission while 48 were sedans with automatic transmission.

Additional information on the 144 Swiss CKD sedans can be found in the detailed statistics below. For example, option AA4, since it is specific to Switzerland, tells us that all 144 of the sedans were Monzas. Looking at the other option details with the number "144" in mind, a picture of how these sedans were equipped emerges:

It sure would be fun to find one of these cars for confirmation!

Belgian CKD notes

Dave's article gives figures for the number of CKD and SUP Corvairs imported into Belgium for calendar year 1966, which means some of the cars were of the 1967 model year. Fortunately, after several rounds of deduction from the summary and detailed statistics, I was able to determine how many Belgian CKDs of each model were produced:

Concerning equipment for these CKDs, the following can be said:

The '66 Antwerp-assembled Corsa coupe owned by Eric Boughner of Clay Township, MI confirms most of these items. (Check out the information provided by Sam Christ, the previous owner.)

Last car built each month

When Dave had complete access to GM Canada's archives he was able to find out the serial number and model of the last car built each month during the 1966 model year (except September). Here's the breakdown:

Dave also found that the very first car (serial 0001) was a 500 coupe built on September 8, 1965. The build date of the very last car (serial 6137) was June 16, 1966.

You can derive the full VIN of the last car built each month (except September) from the information above. The first digit is always 6, indicating the build year. The next five digits are the often-seen model number. The last six digits are the serial number. For example, the VIN of the last car built in February is 610537004432. 

What happened after 1966?

1966 was the last year GM produced Corvairs in Canada. In 1965, the U.S. and Canada signed the Automotive Products Agreement (Auto Pact). From Canada's point of view, Auto Pact removed tariffs for cars and parts imported by U.S. auto manufacturers, provided that the U.S. manufacturers made certain commitments to jobs and investments in Canada.

GM Canada began importing Corvairs in 1967, which was certainly more cost-effective due to the very low production volume, while maintaining production of other models in Oshawa. (The pact only specified that a certain proportion of the total number of cars manufactured in North America be made in Canadian factories, not specific models.)

Detailed statistics

The detailed information exists in two reports: the "1966 Corvair Equipment" report (11 pages) and the "1966 Corvair CSL" report (2 pages). (CSL stands for Canadian Special Listing, the Canadian equivalent of COPO [Central Office Production Option]. Thanks to Dave Newell for this bit of info.) Check out this sample of how the original 1966 Corvair Equipment report looks. Note that both reports were produced on September 12, 1966, more than a month after the summary report discussed above.

Keep in mind the following when reading the data below:

1. The information is mostly complete now, but there are still some holes. Dave Newell helped decode many of the unfamiliar options but there were even a few that he did not have record of.
2. The original reports do not consistently break down the data. For example, for option A01 (tinted glass, all), the Corvair Equipment report only provides numbers on coupes vs. sedans vs. convertibles while for option C48 (heater delete), the report breaks down the data by each individual model and body style.
3. All of the data and notes below come directly from the reports except where enclosed by brackets: "[ ]". I did reword most things to be more clear than the extreme shorthand used on the original reports.
4. The reports often have normal entries then entries followed by the letter "L". After puzzling over this for several days, I found some summary information in the 1966 Corvair Equipment report which equates "L" with CKD units. Therefore, any line of the original reports that had an "L" suffix is represented below as CKD. Dave Newell confirmed that the the presence of either "L" or "R" indicates CKD. "L" indicates CKD cars with left-hand drive. Some models of GM cars (Impala and Chevelle, for example) could be built with right-hand drive ("R").
