1979 Pontiac Grand Am Coupe: Ultra-Rare 4-Speed Manual In A Sporty Flop

The 1978–1980 Pontiac Grand Am was strike two for Pontiac’s sporty “import alternative” intermediate: Though praised by contemporary reviewers for its capable handling, the downsized second-generation Grand Am sold even worse than its 1973–1975 predecessor. This attractive Nocturne Blue ’79 with the extremely rare 4-speed manual transmission shows off the pros and cons of this now-obscure, underappreciated Pontiac.

Although its flexible urethane nose treatment was originally intended for the 1973 GTO, Pontiac ended up trying to pitch the first-generation Grand Am as something rather different: a “more-than-acceptable alternative to the costly imports,” with a crisper-than-usual radial tuned suspension that was supposed to make it a great American road car. The buff books were cautiously pleased with the chassis, took a jaundiced view of the overripe styling, and felt the Grand Am was still too big and too unsophisticated. Buyers mostly stayed away, and the Grand Am disappeared after 1975.

Pontiac spent the ’70s watching the growing popularity of imported cars and the car magazines’ increasingly obsessive love affair with BMW, and decided maybe the original Grand Am had just been a little ahead of its time. With the introduction of the downsized A-body LeMans line for 1978, the Grand Am was back. The 1978 Pontiac brochure’s reintroduction opened with an appeal to nostalgia that elicits some snickers if you know how poorly the first-generation Grand Am had sold and the lukewarm reception it had received even from the buff books it was apparently supposed to court:

For a few glorious years in the early seventies one car came blazing on the scene to establish itself as an impressive American grand touring car. Well, now it’s back. With a new size. A dramatic new design. And the same exciting driving flair that once set your heart on fire. … It’s as if Grand Am had never left.

The time away had done the Grand Am some good. The downsized coupe was almost 9 inches shorter and over 600 lb lighter than the old one, and its styling was less overwrought than before. I find the Grand Am more palatable than the 1978–1980 Grand Prix, although it was also less distinctive — it really just looked like a fancy LeMans, which it was.

Something that struck me, looking at these pictures, is that the downsized A-body cars tended to look smaller than they actually were. Without a clearer external reference point, you’d think this Grand Am was only a little bigger than the later J-body Pontiac J2000/Sunbird, but it was really 198.6 inches long and weighed around 3,500 lb, with over 57 percent of that on the nose. This ended up having a lot to do with how the Grand Am performed.

Pontiac claimed the Grand Am was “an extension of the GTO philosophy in a much more sophisticated car.” However, the raw thrust that had been the old GTO’s stock in trade was absent. Most of these cars had the mild-mannered Pontiac 301 V-8 in L27 two-barrel or L37 four-barrel form. The latter, with 150 net horsepower, was the most powerful engine available on the 49-state Grand Am, and the only V-8 available with the 4-speed manual transmission in 1979. (Except in California, it was theoretically possible to order a Grand Am with the 3.8-liter Buick V-6 and 4-speed stick, although I doubt any were actually built that way.)

The 4-speed was extremely rare in these cars. While the figures I have don’t separate the Grand Am from the LeMans and Grand LeMans, total 4-speed installations for all three models numbered only 375 units. Car and Driver tried to get one for a 1979 comparison test that pitted the four-door Grand Am against a BMW 528i, but Pontiac said none was available, citing production problems. It was no great loss: Motor Trend tested an even rarer 1979 Grand Prix with this same 301-4V/4-speed powertrain and found that while the linkage was fine and the ratios seemed well-matched to the 301 engine, the combination of soft engine mounts and a heavy clutch made it miserable to drive in traffic. The vast majority of Grand Am and Grand Prix buyers ended up with the TH200 automatic, which was easier to drive, but suffered so many reliability problems that the Federal Trade Commission launched a formal complaint against GM in 1980.

Car and Driver‘s automatic ’78 Grand Am test car needed 11.5 seconds to reach 60 mph and ran the quarter mile in an uninspired 18.7 seconds at 76.3 mph. (Suspiciously, C/D‘s 1979 four-door Grand Am automatic was 1.6 seconds quicker to 60 and through the quarter mile, despite unchanged power, slightly more weight, and a lower numerical axle ratio.) The Motor Trend 1979 Grand Prix 4-speed, which was about 90 lb heavier than a comparable Grand Am, took 11.8 seconds to hit 60 mph. This kind of performance was perfectly adequate for most uses, but a street racer the Grand Am was not, and Car and Driver grumbled that it was hard to fully exploit the capabilities of the chassis because the throttle response was so lethargic.

Handling was supposed to be the real forte of the Grand Am. Its chassis tuning followed the usual ’70s GM recipe: bigger tires (205/70R14, in this case), firmer springs and shocks, and lots of roll stiffness. On smooth surfaces, its absolute cornering power was decent for this era, and Pontiac specified a different recirculating ball power steering box that offered more feedback than most A-body cars.

However, with so much weight on the nose and a fat front anti-roll bar, the Grand Am still understeered heavily, its steering was awfully light for a performance car, and its ride still got unsettled on rough roads. It was still happiest in fast highway cruising, where it was quiet and smooth. For a ’70s domestic car, the Grand Am had above-average poise, but it wasn’t extraordinary.

Like the other downsized GM A-bodies, the Grand Am had better space utilization than its predecessor. You could now carry four adults in a Grand Am coupe without too much squawking, which was a welcome change of pace for a two-door intermediate.

Unfortunately, Pontiac product planners had made many compromises that tended to undermine the credibility of the Grand Am concept. You’d think an “American grand touring car” would have bucket seats, but for 1978 and 1979, somebody insisted that a cheap non-split bench seat ought to be standard. Bucket seats were available (as was a 60/40 split bench), but they cost extra.

The availability of bench seats meant the Grand Am couldn’t have a central handbrake, so it was stuck with the same foot-pedal parking brake as the rest of the A-body line. This meant that on manual transmission cars, the clutch took a beating when starting on steep hills, something Motor Trend found frustrating in their Grand Prix tester. Also, if you did order buckets, the driver-side rake adjustment that had been a prominent feature of the original Grand Am was conspicuous by its absence. (You could order a reclining passenger seat, but the driver’s seat back angle was fixed.)

The Grand Am was available with a tachometer and a set of secondary “rally gages” to fill out the various dashboard binnacles, but you paid extra for those, and the oil pressure and temperature gauges tended to be obscured by the steering wheel rim. (If you’re wondering, the tachometer on this car was broken at the time these pictures were taken, which is why the tach needle is stuck at 5,300 rpm.) One minor but worthwhile change for 1979 was a switch to more legible white-on-black dials; the 1978 LeMans and Grand Am had used Buick-like silver instrument faces.

None of this was compelling enough to generate much buyer interest. Grand Am sales for 1978 amounted to 7,767 coupes and 1,865 sedans. For 1979, Pontiac moved some previously standard equipment to the options list to cut the base price by almost $400. This didn’t help (especially since adding back the deleted features made the 1979 Grand Am more expensive than the ’78), and sales slipped to 4,021 coupes and 1,865 sedans. For 1980, the unwanted Grand Am sedan was dropped and Pontiac standardized many of the previous sporty options, including buckets and console, the Rally IV styled wheels, the 301-4V engine, and automatic transmission. Unfortunately, that made the Grand Am around $900 more expensive than a base Grand Prix, which proved to be the death blow. Grand Am production fell to 1,647 cars for 1980, and Pontiac once again called it quits.

Looking at the 1978–1980 sales figures, I think the problem was not so much with the Grand Am concept as with the LeMans on which it was based. Although Pontiac was doing very well in this period (their 1979 model year production totaled 907,412 cars, outstanding by any standard), each of their mainstream car lines was a mediocre seller. Total production of the 1979 A-body intermediates (LeMans, Grand LeMans, Grand Am, and wagons) totaled only 136,938 cars, far fewer than either the Firebird or the still very popular Grand Prix.

I don’t know if contemporary buyers didn’t like the styling of the downsized LeMans or just didn’t think it was a good value compared to a Malibu or a Cutlass, but its sales were poor. It’s hard to sell a specialized version of a weak or unpopular product unless the special edition is truly transformative, and the virtues of the Grand Am were too subtle for that.

When the second-generation Grand Am was still in showrooms, Car and Driver admitted that it was “a poor relation” compared to the great Pontiacs of old, but buzzed excitedly about its tremendous potential and all the cool stuff in the Pontiac development pipeline (none of which ever reached production, at least in the A-body line).

When Pontiac revived the Grand Am for a third go-around with the 1985 N-body line, they chose a very different path. Instead of trying to make the third-generation Grand Am drive like a BMW, Pontiac made it LOOK as much like a BMW as they could get away with, for about half the price of a 318i. (The N-body Grand Am handled competently enough, and it was offered with a “Driver Enthusiast Package” with a Y99 rally suspension, but that was definitely not the principal selling point.) This turned out to be a huge hit — a reminder that for all the latter-day nostalgia about the original GTO, it had been first and foremost a supremely well-marketed car, whatever its actual performance. Pontiac had had to relearn that particular lesson in the ’80s, but it paid off. The N-body Grand Am was a great success in a way its predecessors never were.

This 1979 Grand Am is an uncommon car — one of 375, one of 4,021, however you want to slice it — and in many respects an unusual one. Compared to its storied ancestors, it was short on speed, and the powertrain situation was pretty hopeless, but it was a rare sporty Pontiac that tried to sell the steak more than the sizzle. It sold for $20,041 in August 2024.
