Vintage Car Life Review: 1969 Pontiac Grand Prix Model SJ – “Tiger In Tuxedo”

 

Is this the grandest Grand Prix? If you could poll every living Pontiac fan, the 1969 GP would stand a good change of coming out on top for its balance of style, swagger, and speed. The contemporary automotive press loved it too — and none so much as the editors of Car Life, who were so impressed that they gave Pontiac a special Engineering Excellence Award for it. Here’s their February 1969 road test of the most desirable 1969 Grand Prix, a Model SJ with the rare 428 H.O. engine.

It’s no great surprise that the 1969 Grand Prix was a big hit with the buff books. The B-body Grand Prix, which had been so handsome back in 1962 and 1963, had seemed to lose its way as it got bigger; the 1968 edition was as soggy in concept as it was in road manners. The 1969 car was a different story: Instead of a dressed-up full-size Pontiac, it was now a long-nose version of the midsize Pontiac GTO, with squared-off new styling featuring a formal roofline whose tooling costs Pontiac had agreed to split with Chevrolet (which would shortly use it for the 1970 Monte Carlo). The Grand Prix was a personal luxury coupe in price and positioning, but mechanically, it was a dressed-up muscle car — Car Life called it a tiger in a tuxedo.

This wasn’t the first Car Life Engineering Excellence Award, but the magazine decided that rather than the usual trophy or plaque, they would commission a unique award that would be “as interesting a design effort as the original car was.” They contracted San Francisco Bay Area sculptor Don Conrad to create one of his signature kinetic wire sculptures, using a series of thin stainless steel wires on a lacquered aluminum base. The nature of the sculpture (combined with the usual late ’60s indulgence in print design) made it difficult to photograph:

What you don’t see is the motion, reflection, and sparkle from the tiny wires (no engineering specifications, OK?). The slightest air movement sets the sculpture into motion; and any shadows or lights crossing it set off a shower of contrasting lights.

However, they did include a photo of Conrad working on it:

Car Life publishers John R. Bond and Elaine Bond presented this award to Pontiac general manager John DeLorean about a week before Christmas 1968. It was more or less DeLorean’s last hurrah: Around the time this issue was on newsstands, he departed Pontiac to become general manager of Chevrolet.

While the 1969 GP did merit a certain amount of editorial enthusiasm, describing as “the least compromised car in America” seems a little silly if you understand (as the CL editors certainly did) that the Grand Prix was essentially a stretched “A-Special” version of the familiar Pontiac A-body intermediate platform, and had been developed in unusual haste. Indeed, the engineering rundown elsewhere in this issue acknowledged, “Lack of development time required the Grand Prix designers to utilize components from existing Pontiacs … a new blend of existing parts.” So, while the new Grand Prix was a well-considered compromise in many respects, it was most definitely a compromise.

The late Pontiac ad man Jim Wangers said John DeLorean’s goal with this car was “to capture the spirit and essence of the old Duesenbergs of the 1930s. Great cars, very high-performance road machines with all the trappings of the luxury marques of the day … He even insisted Pontiac use the old Duesenberg model designations, J and SJ.”

In the Duesenberg line of the late 1920s and early 1930s, the “S” in Model SJ stood for “supercharger”; this 1935 Model SJ was once owned by Duesenberg president Lucius B. Manning, and now sports a recreation of its original Gordon Buehrig-designed dual cowl phaeton body / Darin Schnabel — RM Sotheby’s

 

That was all very romantic, but the Duesenberg was a toweringly expensive luxury car of a kind Detroit hadn’t even tried to build in years. I think Car Life‘s assessment of the concept was probably closer to the mark:

The crew at Pontiac must have been thinking: “What are we going to sell to the young guy who bought the GTO in ‘64? He’s older now, making more money, a little settled down now that he’s married, and on his way in a good career. Things are good, and he’s ready to be spoiled. But he doesn’t want to sacrifice the thrill of driving. What is being built that combines GTO-style performance with luxury?”

Enter the grandest of the Grands Prix, the luxury enthusiast’s car.

As DeLorean had ordered, the base 1969 Grand Prix was known as the Model J. This came with the 350 hp 400 cu. in. (6,554 cc) four-barrel V-8 from the GTO, a heavy-duty all-synchro three-speed manual transmission, and moderately plush trim with fake wood trim on the dash and doors. A low-compression two-barrel 400 (RPO L65) with 265 hp was a no-cost option, available only with automatic, while the 370 hp 428 cu. in. (6,991 cc) L79 was optional for $57.93.

The Model SJ was actually a $244.34 option package, RPO Y97. As Car Life explained:

The basic SJ package includes a 370-bhp/428-cid engine, power disc brakes [in front only], performance rear axle ratio, automatic leveling rear airbag/ shocks (they stiffen the suspension as well as keep the chassis level when loaded). But wait. Also on the option list—the business end—is a 390-bhp H.O. engine, a handling package, a 3.55:1 axle ratio, and four-speed and Turbo Hydra-Matic transmissions. In other words, all sorts of things not found in the option lists for other luxury cars. Ours was loaded—all the good factory stuff including the Turbo Hydra-Matic. We had hoped to disguise an enthusiast’s toy in a luxury package.

With the SJ Group, as the package was called on the order form, the 428 H.O. engine was an additional $119.01. (You could also order it on the Model J, for $176.94.) Turbo Hydra-Matic or four-speed manual (with close- or wide-ratio gears) was an extra $227.04. The Ride & Handling package was $9.48, while the heavy-duty Safe-T-Track limited-slip differential was $63.19.

It’s not entirely clear if you could actually order the 3.55 axle with air conditioning — the AMA specs say that ratio wasn’t available with air on manual-shift cars, and indicate that the 428 H.O. got a 3.23 axle with air. Given Pontiac’s track record, it’s not out of the question that the Car Life test car had a combination of options not normally available in the wild.

Reading the AMA specs reveals that while Pontiac quoted the same gross outputs for most of its 1969 engines regardless of transmission, automatic cars actually had different camshafts. The difference in cam profile was most pronounced on the 428 H.O.: The camshaft in automatic cars had less duration, less overlap, and fractionally less lift than with manual shift, so cars with Turbo Hydra-Matic likely made less power than ones with manual transmissions. Pontiac’s official output ratings in this era had to be taken with a grain of salt.

The caption under the photos at the top of the page reads, “SURPRISING CORNERING flatness and predictability made GP a sleeper in the handling department, yet ride was pleasant.”

Car Life said they had picked up their Model SJ test car during a rainstorm:

It was still raining as we arrived at our deserted stretch of winding test road . . . but we started exploring its road manners in curves and on ridges anyway. The Grand Prix devoured the slick turns, and the suspension responded brilliantly with both tremendous feel and feedback from the roadway.

It was not until the following day when it became necessary to wring the car out around brutal curves all over again for the photographer that we took note also of our own nonchalance in driving the car so vigorously. We are used to doing this sort of thing with Supercars and Ponycars. We expect the better ones to handle with just as much predictability and finesse. At a break in the shooting session, though, we climbed out of the car, looked back at it, and did a double-take. For two days we’d driven the car as though it were an enthusiast’s workhorse. not one of the most luxurious cars produced in America. But luxury certainly was parked at the side of the road. It was as though cars had been switched when our back was turned.

They found this especially impressive given the GP’s nearly 4,200 lb curb weight. (I’m not sure if they actually weighed their test cars at this point, but their quoted 4,180 lb curb weight seems a bit low for a fully loaded Model SJ — based on the AMA specs, I would estimate something closer to 4,250 lb. However, it was still almost 400 lb lighter than the Thunderbird CL tested in the same issue.)

Car Life had also tried the milder Grand Prix Model J, both a press fleet car and another car borrowed from a Costa Mesa dealership, but while they found its ride and handling quite decent, their Model SJ was a cut above:

Our test car had the extra help it takes, in the form of stiffer springs, sway bar and improved shock valving. Granted, that sounds as though we were trying to take the GP right out of the luxury class and turn it into a Supercar. Instead, we believe the options enhanced the overall stability and ride. Instead of the heavy, pitchy, mushy feel one associates with the personal/luxury cars, the Grand Prix SJ felt well attached to its suspended members, and they to the road. All without discernible ride harshness. Instead of detachment, we got intimacy. And while its soft ride suggested it shouldn’t corner fast, it simply did.

The car’s cornering attitude is fantastically flat, not unlike that of a genuine race car (we race a lot). That, combined with its near-neutral handling and responsive steering, ranked it among the most predictable American cars we’ve tested … Besides the stiffer springs all around, the Super-lift rear shocks added a bit more rear roll stiffness and took out most of the understeer.

Interestingly, the Grand Prix still didn’t use a rear anti-roll bar, although it would have been easy enough to add one from the Oldsmobile 4-4-2, whose rear suspension was very similar.

In terms of handling, the Grand Prix had one useful advantage over the GTO and 4-4-2: Shifting the front wheels forward allowed the engine to sit farther back, making the GP a bit less nose-heavy than its A-body cousins. Car Life estimated its weight distribution with only the driver at 56/44, compared to 58/42 for a Ram Air GTO.

Adding to the GP’s handling ability was its variable-ratio power steering, which was quick (2.9 turns lock to lock) and actually provided a modicum of feedback. Power steering was still a $115.85 option on the 1969 Grand Prix, although 99.7 percent of buyers ordered it. Car Life was very keen on it:

GM’s variable-ratio power steering has gotten unanimous praise this year from CAR LIFE testers. It has even converted one staffer who has always thought power steering was part of the Communist conspiracy. Now he admits it is a fine combination of responsiveness, ease and road feel. And though it puzzled us at first, the small steering wheel blends well with the overall character of the car. It lends itself well to two-arms-straight driving that seems ideal for the steering response and handling.

Even with the 428 H.O. engine, the Grand Prix was a little too heavy to deliver really startling straight-line performance, but Car Life remarked that it “could very likely have embarrassed some so-called Supercars. With the 390 hp engine, TH400, and 3.55 axle, the spec panel reported:

  • 0 to 30 mph: 2.9 sec.
  • 0 to 60 mph: 6.7 sec.
  • 0 to 100 mph: 16.0 sec.
  • Standing ¼-mile: 14.1 sec. at 95.3 mph
  • Passing, 30 to 70 mph: 5.4 sec.

They listed a top speed of 129 mph, but that was pretty clearly a calculated figure, which presumed that the engine could pull to redline in top gear; I think around 120 mph would probably be more plausible.

Elsewhere in this same issue, Car Life had asserted that GM’s new single-piston vented front discs would be “a Grand Prix delete option, that is, all Grand Prix are built with them unless the buyer orders front drums.” However, the brochure describes power front discs as an extra-cost option, and it appears that they were only technically standard with the SJ Group. (Curiously, disc brakes aren’t mentioned at all in the GP section of the 1969 Pontiac Accessorizer, although Car and Driver‘s Grand Prix road test reported a list price of $71.62 for front discs on a Model J). In any event, 99.9 percent of 1969 GPs were built with front discs, so it worked out about the same in the end.

Rally II styled wheels were $63.19 extra on a 1969 Grand Prix, while G70-14 tires (redline or whitewall) added $97.95 / Bring a Trailer

 

Car Life found the Turbo Hydra-Matic well-matched to the 428 H.O. engine — so well that they didn’t see the point of the manual transmissions, remarking that “it seems out of character to have to shift a car of this caliber manually.” Buyers apparently felt similarly: Only 713 ordered a four-speed gearbox, and just 301 took the three-speed manual transmission.

Elsewhere in the issue, the Car Life editors praised the Grand Prix for having the “most rational instrument panel to come along in recent memory,” with the cockpit-themed wraparound design of which GM stylists had recently become enamored. In the main text, they conceded:

It could cause a few family fights; but the usually shared controls are still on the passenger’s side—radio, temperature, lighter (compare it with some of the thoughtless positioning in a similar arrangement on Ford’s LTD).

While the HVAC and radio controls were on the right side of the steering column, adjusting the temperature or changing the radio station from the passenger seat meant reaching behind the steering wheel, and would probably have to be done by feel. Some contemporary rivals were worse, but I wouldn’t rate this arrangement too highly for convenience, and as on other GM cars of this era, the wraparound dash so blocky it looks more like a Brutalist building than a cockpit.

Car Life noted that their test car didn’t have a tachometer, which it could have used. This was one of a number of disagreeably cynical aspects of Pontiac’s merchandising in 1968–1969: Although the SJ Group included the Rally Gauge Cluster optional on the Model J, it didn’t include a tachometer, and if you wanted one, you had to either buy the whole gauge package again for an extra $84.26, or else pay the dealer $75.00 to install one of Pontiac’s gimmicky hood-mounted tachometers.

Pontiac charged an outrageous $142.18 for the GP’s optional Cordova vinyl top, which listed for only $100.05 on a GTO and $115.85 on a Catalina, Executive, or Bonneville / Bring a Trailer

 

As you may have gathered, Car Life was very impressed by the GP Model SJ, concluding:

Unlike the run-of-the-mill luxury/personal cars which are styled to look like they can do things they can’t, the Grand Prix does things that look impossible. In other words, it’s a duesie!

For all the fanfare, I think that describing the 1969 Grand Prix as a great engineering achievement was a stretch. As a merchandising concept, however, it was brilliant: It took 360 lb and many dollars out of the GP, while wrapping it in new styling handsome enough that no one balked that Pontiac had actually raised the price by almost 5 percent.

Moreover, the 1969 Grand Prix’s styling hit the sweet spot between modern-sporty and neo-classical luxury. Comparing it to the contemporary Thunderbird Landau, I can’t help thinking that the Pontiac studio had found the answer for which the designers of the muddled 1967–1969 Glamour Bird had been struggling. (The Grand Prix outsold the Thunderbird by more than 2 to 1 in 1969.)

I also can’t help thinking that the buff books would have been less ecstatic about the Grand Prix if corporate policy hadn’t prevented Pontiac from just offering the 428 engine in the GTO. If the 428 H.O. had been a regular production option on the 1968 or 1969 GTO or Firebird, the enthusiast press would probably just have shrugged their shoulders at the Grand Prix, making some coy comments about its styling while reminding loyal readers that there was better performance to be had by ordering the same powertrain in a lighter car.

Whatever the car magazines thought, it doesn’t appear that most buyers saw the Grand Prix as their ticket to a bigger-engine A-body Supercar. Back in 1989, Fred H. Simmonds calculated powertrain production totals for the 1969 Grand Prix and found that only 1,105 cars had the 428 H.O. engine, and only 11,083 had the SJ Group. Four out of five GP buyers were content with the base 400 engine (although unfortunately Simmonds’ tally doesn’t distinguish the standard four-barrel engine from the rare two-barrel L65 low-compression engine, a no-cost option).

More important from Pontiac’s standpoint was that the Grand Prix was a popular car that could be optioned up to more than $6,000. (The Car Life test car listed for $6,095, the green car in the color photos for $6,042.36 with destination.) DeLorean said later that Pontiac made a profit of up to $1,500 a unit on these cars, a very handsome return on a modest investment. As with so many of the performance cars of the 1960s, the 1969 Grand Prix was most muscular where it really counted: on the bottom line.
