CAR and DRIVER ROAD TEST: 1984 Corvette!
Wherein America takes on all comers.

By Brock Yates

 

You have waited long enough. So let's get it over with right now: the new Corvette is a truly stout automobile. It is all that the fevered acolytes so desperately wanted their fiberglass fossil to be — a true-born, world-class sports car loaded with technical sophistication.

Lest such a claim be dismissed as more hyperbolic reverie about the blowzy old doyenne of the boulevards, consider the following:

Item: The roadholding on this new machine is so advanced that we recorded the highest skidpad lateral acceleration — 0.90 g — ever observed with a conventional automobile by this staff. That figure practically trivializes the previous high-water marks, in the 0.82-g range, generated by such exotics as the Porsche 928 and assorted Ferraris.

Item: It is hands-down the fastest American automobile, capable of 140-mph top speeds, 0-to-60 times under seven seconds, and 15.2-second quarter-mile forays at 90 mph. In fact, these figures qualify the Corvette as one of the half-dozen fastest production automobiles in the entire world!

Item: Its braking, thanks to an advanced Girlock four-wheel-disc system, makes the car stop as if it had been dropped into a sand bank. Our 70-to-0-mph brake test produced a stop in a mere 173 feet — seven feet shorter than the best 1982 distance of 180 feet, recorded by a Porsche 928, and not far off the all-time record of 165 feet, set by a Porsche 930 Turbo!

"I'll take all comers. You bring what you want," is the way Fred Schaafsma puts it, and he ought to know. He is part of the tiny cadre of Chevrolet engineers who, while huddled in a temporary patchwork of trailer offices at GM's proving grounds in Milford, Michigan, brought the new car into being. A native of the Netherlands, Schaafsma (real first name: Freerk) is fiercely loyal to the car he helped develop and is proud of its unique combination of qualities: its traditionally lusty big-inch V-8, its fully independent, forged-aluminum suspension with plastic leaf springs, its optional four-speed manual transmission with automatic overdrive in the top three gears, its plastic-over-steel-frame construction. "I was born and raised in Europe, and I know that a car doesn't necessarily have to be like a European machine in order to be good," he says. He and his cohorts openly admit, however, that the Porsche 928 was the "data point" on which a great deal of the Corvette development centered. "When we compared our car against the Porsche, I can tell you there were a lot of good feelings at Chevrolet."

For those who expected the 1984 Corvette (yes, '84 — it will be marketed as such for eighteen months) to be a cross between a Lamborghini Countach and an F-16, there will be disappointment. The shape is clean and forthright, devoid of the phallic silliness that distinguished its predecessor during its protracted career. It comes in a single body style, that of a classic two-seat sports car with a removable, one-piece roof panel and a hatchback. It is 8.5 inches shorter overall than the old car, and its wheelbase, at 96 inches, is two inches shorter. But the new car is beamier by an equivalent amount, which translates into additional interior space, including 6.5 inches extra shoulder room.

A first encounter tends to leave one faintly unfulfilled, as if the long-awaited confrontation should have been more dramatic. But that notion fades as the honesty of the effort becomes evident. This is a dead-serious sports car. It defers to the bizarre only with its video-game instrument panel, which features all manner of multicolored, liquid-crystal bar graphs and digital displays in metric and English. "We were having a little fun with the instrument panel," admits Dave McLellan, the widely respected chief engineer on the Corvette project. "There are a lot of things about the car that go beyond basic needs, and in this sense the Corvette competes with things like fast powerboats and ultralight airplanes. Like them, the Corvette goes beyond serious transportation. This is a sports car, and we wanted it for one simple mission — to go fast."

That it does. Tucked into the optional, high-bolstered sport seat with its power backrest, lumbar, and bolster adjustments (the power activation is as light as and even simpler than a manual counterpart), one is poised for a ride on the outer limits of earth-based travel. Both visibility and control ergonomics are improved, and if one was pressed for a complaint, it would center on the rather clunky linkage of the four-speed manual transmission (all initial models will be four-speed automatics).

One feels more of a part of this machine, thanks to the radically improved suspension and more precise steering. Gone is the old bob-and-weave of the rear end, which often gave the impression that the left and right tires were of different diameters. Gone is the wobbly steering that made the old cars behave like Irish setters on a high-speed scent. Gone is the uncomfortable feeling that you are at the wheel of a rolling cult object rooted in the ethos and technology of another automotive era.

Until the arrival of final understeer, which comes at lateral accelerations unknown to the average driver, the Corvette is race-car responsive. The exotic suspension, upgraded with a sensational Z51 performance handling package (special Goodyear P255/50VR-16 tires with an F1-style "Gatorback" rain-tire tread mounted on 8.5-inch front and 9.5-inch rear aluminum wheels, plus quicker steering, tighter shocks, and heavier-duty bushings, sway bars, and springs), creates handling that can make a quiche-eater look like a serious user of beef jerky and draft beer. The car revels in long, controlled slides. It begs to be steered with the throttle. It forgives ham-fisted operation like no other car on the road, and when driven seriously it will hook up under hard cornering to a point where one begins to wonder if Gordon Murray and Colin Chapman attached sliding skirts and ground-effects tunnels. As Schaafsma says, "You bring what you want."

Perhaps the single most impressive styling component of the machine lies under the full-width, forward-opening hood. There, in naked splendor, is more sculptured alloy than has been displayed on any other production car since the Porsche 928 and the original Jaguar XK-E. It is a stunning sight, especially when one's eyes first meet the forged-aluminum control arms and the engine, trimmed in magnesium castings and black enamel. Nothing is out of place. It is an aesthetic triumph.

All right, then. Is this the perfect Corvette? The answer is close, but no cigar. Some complaints are minor, such as the loss of four gallons of fuel capacity; the major problem is the familiar matter of weight. The Corvette is still heavy, and at 3300 pounds carries no advantage over the old flying dildo. There is argument about its exact poundage, with the Chevy guys dismissing complaints as nit-picking. "Sure, I'd like it to be lighter," says Schaafsma, "and I can take off 100 pounds in a minute. But if a guy can only pick at it because it's 150 pounds heavy, I'll take that."

A broader complaint may arise from those disappointed souls who have been weaned on the notion of the new Corvette as a mid-engined automobile, the Yankee answer to the Ferrari Boxer and the Lotus Esprit. To be sure, the True Believers' appetites were whetted by endless spy shots of "secret" mid-engined prototypes in the 1970s, but by 1978 it had been decided: the new car would be a classic, V-8-powered, front-engined two-seater. "By then we had rejected the mid-engined V-6 concept," says McLellan. "It was simply not a Corvette." Noting the penalties in passenger and luggage space inherent to mid-engine design, McLellan asks, rhetorically, "Where are the successful mid-engined cars?"

Which leads us to the knottiest problem. The car will be expensive — perhaps as high as $28,000 in full regalia. Will this drive the traditional middle-income Corvette buyer out of the market? Will he be replaced in sufficient numbers by wealthy Porsche and BMW loyalists? With a new plant in Bowling Green, Kentucky, geared to build as many as 60,000 Corvettes a year, will the GM moguls be angry and depressed if first-year sales don't meet the target of 25,000 cars? Will the Corvette be a critical success and a commercial failure because of corporate overoptimism? Only time and further examination of this machine will reveal the answer. This much we already know: there is a price for glory, and it is high.

I have too many projects going on and this one needs a new home Now!

This 1984 Corvette was purchased a few years ago and I have purchased several extra parts for it including a new set of tires that have just been installed on the car. The car needs a paint job as someone did not put the right primer under the paint and it is pealing off the front. The interior is in good shape and the engine (77679 miles) and transmission are working good. I have driven the car around here and it runs and drives good. I have $3750.00 in the car and that is all that I am asking for it and everything that I have purchased for it. (extra ECM, Power Chip, fuelpump, radio speakers, new tires and more).

FUEL ECONOMY (from the Car and Driver article)
EPA city driving     16 mpg
EPA highway driving     28 mpg
EPA combined driving     20 mpg
Great performance and good gas mileage too. What more could you want!

I have a 1974 Corvette Stingray that I am restoring also and just don't have the time or money needed for this one right now so I hope that someone can give this great car the TLC it needs.
