1967 Pontiac Grand Prix convertible didn’t catch on

Albert Fredrick Godwin stopped by to point out that our featured 1967 Pontiac Grand Prix convertible was his car. He had displayed it at an annual auto show hosted by LeMay Collections in Marymount. Let’s expand a bit about this fairly rare model.

The Grand Prix was only offered as a convertible in 1967. And even though advertising emphasized the new body style, only 5,856 were produced. That was quite a bit less than the number of GTO or Firebird convertibles which left the factory in 1967.

The Grand Prix two-door hardtop sold much better — more than 37,000 units — but that was still half as much as the glory days of 1963. Production would sink even further in 1968 to under 32,000 units, whereupon John Z. DeLorean would shift the Grand Prix to a mid-sized platform. This proved to be a good move because the full-sized sporty car was becoming an endangered species.

In 1967 the Grand Prix was among the highest-priced Pontiacs, but it continued to share a shortened, 121-inch wheelbase shared with the entry-level Catalina. This gave the Grand Prix a slightly longer-hood, shorter-deck look than the Bonneville, which had a 124-inch wheelbase and a deck stretched another four inches.

The rest of the 1967 big Pontiac line had “elbow” taillights and stacked headlights. Pictured is a Bonneville Brougham four-door (top image) and two-door hardtop (middle), along with a Bonneville two-door hardtop (Old Car Brochures).

Redesigned 1967 model looked better than in 1968

The auto editors of Consumer Guide summed up the big Pontiac’s new sheetmetal for 1967 as having a “heavy look highlighted by bulky, curved rear fenders” (2006, p. 747). A new across-the-board feature was hidden windshield wipers, but only the Grand Prix hardtop eliminated vent windows.

The hardtop carried over a concave roofline that in previous years had been shared with the Oldsmobile Starfire.

All big Pontiacs had a “donut” shaped front bumper, but the Grand Prix received a unique design that wrapped around hidden headlights. In addition, turn signals were partially hidden in triple slats above the grille. This gave the car an unusually low, wide and modern look.

The rear styling of the 1967 Grand Prix was plainer than in previous years. However, the two-slat taillights had a family similarity with that year’s GTO.

I have mixed reactions to the 1967 redesign. In a way it is cleaner than the exceptionally creased 1965-66 models, but it does look heavier.

The 1965 models had a W-shaped rear with faux full-width taillights. In 1966 they were ditched for flat ribbed taillights and a less chrome-filled fascia.

Do you think the 1967 Grand Prix was a stylistic improvement? To my eyes it is easier to say that it has withstood the test of time better than its 1968 successor. A one-year-only sheetmetal redo integrated the roofline into side styling, but the wrap-around taillights are awkward. Why did they bother with such a major restyling for just one year?

Interior was merely a dressed up big Pontiac

The Grand Prix’s interior had top-end trim but otherwise varied little from other big Pontiacs. For example, in the 1967 model pictured below the instrument panel had a ribbon-style speedometer that spread out far and wide. This was a less sporty look than the mid-sized GTO’s more European-style dashboard with round gauges.

One feature that the Grand Prix shared with the GTO was a hood-mounted tachometer. Advertising made it seem like this was a cool thing, but it was likely dreamed up to avoid the expense of rearranging the instrument panel to fit a tachometer.

Pontiac emphasized lush illustrations in its marketing

For 1967 Pontiac published a number of Grand Prix images that appear to have been penned by Art Fitzpatrick and Van Kaufman. In addition, all three of the full illustrations I have posted in this story appear to show a Grand Prix in an exotic European locale. How fitting — a big American car in the narrow streets of Paris!

The exaggerated widths given to the Grand Prix work much better than with the Firebird, which doesn’t look as good drawn out of proportion (go here for further discussion).

The illustrations also give the Grand Prix’s surfaces considerably more color and contrast than would be possible than with photography. Yet all of that effort resulted in much lower sales for the Grand Prix than for the GTO or Firebird.

Grand Prix loses convertible and big-car size

By 1967 the Pontiac brand’s primary appeal was arguably its sportiness, but the public was increasingly associating “sporty” with mid-sized and compact cars. So for 1968 the Grand Prix lost its convertible and the following year the coupe was shifted to a mid-sized platform.

Downsizing the Grand Prix would prove to be one of DeLorean’s smartest moves while head of Pontiac. The top year for the big Grand Prix was in 1963, when production only reached roughly 73,000 units. Compare that to 1969, when output soared to more than 112,000 units — and would peak at over 288,000 in 1977.

  1. I agree with most of the comments, but the best of the Grand Prixs were 1963-1964, in my opinion. The 1965 G.P. grill was over styled, and the 1966 Pontiac’s nose was in my opinion, too extended (as was 1968’s beak). The 1967 G.P. was adventurous and predicted the 1968 full-size and intermediate Pontiacs return to horizontal headlights.

    I believe that the reason the 1967 G.P. convertible was not a “hit” in sales is because the desire for full-size luxury convertibles was in decline nationwide among most domestic full-size makes. The last four-place Thunderbird convertible was 1966. G.M. kept B-body convertibles until 1975-1976 and only later offered personal luxury convertibles through special third-party suppliers such as A.S.C. I also think much of the desire to have open-air driving was satisfied by moon-roofs and T-tops.

    Finally, I would also believe that the connecting of isolated segments of “super-highways” that became continuous interstates made top-down traveling a buffeting experience, and with factory air-conditioning, driving in “fresh-air comfort” was only the push of a button or slide of a lever on the dashboard away.

  2. Pontiac had a whole bunch of convertibles that year. The Bonneville on a longer wheelbase, and Catalina with three trim option, near models in their own right..Base Catalina, the 2 + 2 sporty, and the Ventura full size muscle. One would be squeezed out.

    • That’s true — and overall Pontiac convertible production would have been meaningfully lower in 1967 except for the new Firebird. And in 1968 the only bright spots were the Firebird and the redesigned GTO; otherwise convertible output fell further.

      It could have made sense to keep the Grand Prix convertible in 1968 if the rear end continued to share sheetmetal with the Catalina, but it’s hard to see how sales would have been high enough to pay for a unique trunk lid and rear quarter panels.

  3. Steve,
    The hood tachometer on the Grand Prix was an excellent decision, as the 1966 & earlier GP tachometers were mounted down below the dashboard, on the center console. That location was too far away from the driver’s line-of-sight out the windshield, requiring the driver to swivel their neck down & to the right just to see the tach, then back up to windshield level. Drivers using a tach to determine when to shift know you need the tach as close to the straight line-of-sight as possible.

    40 Years ago I bought a nice original triple black 1966 tri-power 421/4-speed GP, and the original owner had replaced the tach with a SUN tach on the steering column, “So he could see it”. Paid $1,500 for it, wish I still had the car!

  4. The ’67 front end was stunning, they should have kept the ’66 taillights or a modified version of it. The ’67 rear was a let down.

  5. Thanks or the compliments the fathom blue convertible is my car.I was very surprised to see this article. The car is really quite rare as it is equipped factory 428 HO 4 speed manual car with AM/FM and reverb, power windows and top. Best number I have heard is that 27 Grand Prix came equipped with the 428 HO motor

    • Albert, it’s a lovely car so thank you for displaying it at LeMay’s. I find that the most interesting cars at their annual show are mostly those presented by their owners.
