1973 Grand Am Road Test, Road & Track March 1973


COMPLETE TEST DATA AT THE BOTTOM of this page.

A lot of fuss is being made by three divisions of General Motors this year about how "European" their intermediate size cars are in certain ways. Chevrolet inspired by the handling of a Mercedes their general manager had been driving, gave the Monte Carlo's steering a lot of caster to capture the German car's straight-line stability. Pontiac came up with a variation on the common (among all GM's intermediates) chassis called the Grand Am, which set out to imitate some of the flavour of European GTs. Oldsmobile did a Cutlass Salon with much the same flavour as the Grand Am - tightened-up chassis, and a somewhat European-style interior. All three of these cars have front disc brakes and steel-belted radial tires as standard equipment, and the Pontiac even has a steering-column headlight dimmer switch! All pretty alien for U.S. cars.

So we just had to try these machines and the Grand Am was the first to be delivered into our hands. The model is available as coupe or sedan with 112 or 116 in. wheelbase respectively, ours was the coupe. It's overall length, considered "intermediate" by the U.S. car industry, is what we call large at 208.6 in. and it weighs over two tons. As a variant on the LeMans series, it does go in the direction of a European sedan, combining a lot luxury equipment and extensive sound deadening with a firm (for the U.S.) chassis: it has the stiffest front anti-roll bar in the series and a rear bar as standard (though not as stiff as the '73 GTO's). Wheels and tires are also proportionally huge 7 in. wide rims and G70-15 radials. So it's what you might call a serious road car.

Would that it's body were as serious. There seems to be no letup in the Detroit design philosophy at least yet, of designing cars for maximum 'gee whiz" effect and never mind logic or form-follows-function. The Grand Am suffers. besides its size, elaborate sculpturing that seems to be straining to recall the " Glorious Past", imitating hoods of the 1930s, fenders of the 1940s and the general decadence of the 1950s when automobiles went their merry' way, ignoring any logical or environmental considerations. It's certainly not that GM Styling is incompetent; cars like the Vega, Camaro or Firebird show how well the giant company can do. But the Grand Am is not really in the same class-it's merely commercial-and in five years it'll look merely old fashioned.

All right. If we can't take the Grand Am's outer skin seriously, what about its interior? Here the designers and decorators have made an attempt at being European. The vinyl upholstery of our test car was monochromatic, if somewhat over-pleated. and all instruments and controls are set into a well-arranged panel overlaid with a thin veneer of mahogany. The gauges are round, well marked and fully visible and there's color coding on the heat control just like that on some Europeans. The front seat have typical U.S. electric adjustments (an option on the test car) but in addition there are distinctly Continental-style knobs to adjust seatback angle and lumbar support firmness. On the latter we couldn't detect much difference, and overall the seats were seemingly over-contoured and difficult to get comfortable in. The steering wheel is very nice-simply designed and with a fairly thick padded rim, but angled awkwardly off to the right. The interior is not particularly large for such a large car, but that's normal U.S. practice.

Whether or not the seating is very good, the interior is most assuredly well climate-controlled and quiet. The big engine loafs at freeway speed. totally inaudible beneath the subdued level of wind and road noise.

A large variety of engines is available in the Grand Am, and they're all big ones, ranging from the 170-bhp. 400-cu-in. V-8 of our test car (2V carburetor. single exhaust) to what is nearly the most powerful engine in any domestic car this year, a 310-bhp. 455-cu-in. V-S. The mild engine is typically smooth and quiet. generates torque of a magnitude capable of spinning the rear wheels freely on a standing start, and uses fuel the the tune of 11 mpg in average driving. It drove through the excellent, smooth Turbo Hydra-matic in our test car.' 3-speed and 4-speed manual gearboxes are to be had with certain of the more powerful engines. As the Road Test Results show, our car was not fantastically quick. but its acceleration was brisk enough for real driving conditions and any hotter engine would offer that much more. The engine of the test car suffered normal 1973 drivability quirks ~ pronounced lean surge at sub-urban steady speeds and poor cold starting-plus an unexplained occasional forward surge as the engine seemed to open its own throttle a few extra degrees.

The Grand-Am's road behaviour combines ride and handling to a higher degree than earlier American efforts at "road cars", but it's still clear that the car's suspension system isn't a sophisticated one. Over good roads the ride is comfortable without making passengers seasick-quite satisfactory. But when the going isn't so good, it turns out that the big Pontiac develops some pretty standard U.S. car traits: the front end floats when coming out of gentle undulations at speed and one has to slow down for a dip to prevent the front and rear suspension from bottoming.

For cornering on a smooth, steady turn, the Grand Am on its big radials will work up to a pretty decent lateral loading - nearly O.7g, just below a BMW Bavaria in standard form. If the corner isn't a steady-radius or smooth one, however, the Grand Am gets dicey-simply because its power steering is almost devoid of any road feel. Thus any corrections needed to keep the car on course have to be made on an observe-and-try basis rather than on the basis of direct reactions and counter-reactions at the wheel. This power steering is what we've been getting from domestic carmakers for years: power steering fo parking, not for driving. If the road is wet the problems are compounded since the Uniroyal radials used have little side grip in the rain. Braking is somewhat more satisfactory and the Grand Am's stopping distances on dry pavement are truly short. The extreme forward weight bias of the car helps insure that it's the front wheels that lock up and this they do with a vengeance so that it takes a lot of foot modulation to unlock them. But at least the car doesn't go slithering about.

In another area of 'handling," city-traffic maneuverability the size of the Grand Am is somewhat limiting. Thanks to the stylishly louvered quarter windows, one can see to make simple lane changes well enough but the angle of these limits which direction they allow vision, and for instance they may not allow the driver to see what's coming from the right at an intersection with a road at an acute angle in that direction. We suppose it's going to take a government standard on vision (there is one already proposed) to stop this sort of monkey business in a critical area of car safety-outward vision.

The Grand Am is a car that was designed for effect, and it certainly affects different people different ways. It drew admiring glances and even an occasional question from those who own cars of comparable size and styling Others simply sneered at it. But the most remarkable reaction of all was that of the would-be track star who, upon discovering the Grand Am parked outside overnight, was inspired to take a running start from the rear and stride right up over its deck, roof and hood.

Wonder if the GM stylists had that in mind?
