Testing The Thunderbird

Ford's latest creation is a speedy, sporty answer to the growing U.S. demand for power and comfort with a sports car thrill

In the last three years, the number of imported sports cars on U.S. highways has jumped by 160%—or one for every 2,500 Americans. The auto industry, awakening to the $340,000,000 business this represents, has countered with various new models of its own. The latest of these is the Ford Thunderbird, due for an October unveiling. To subject this new car to a critical appraisal, SI sent Motor Columnist John Bentley out to the Ford works, where he put the Thunderbird through her paces and wrote the exhaustive report which follows below.

It was not a pilot model Thunderbird which the Ford Motor Company rolled out for me, but the Number-1 production model of a line which will shortly be geared to a monthly output of 1,000 cars—a big concession by an industry which until very recently still failed to realize that the clink of small change from the cash registers of imported-car dealers was growing to respectable crescendo. Ford's newest baby, as I first saw it, was a lavish car which can be equipped, at extra cost, with all the gadgetry of a prize convertible—and more. The one I drove featured Ford-O-Matic transmission, power brakes and power steering, as well as power-operated seat and windows. Also optional, fortunately, are dummy wire-wheel discs and a detachable hard top which can be provided in place of the standard folding top—a neatly folding affair with spring-loaded bows, easily handled by two people and designed to tuck down out of sight behind the seat.

SLEEK, DOCILE, FAST

It is a sleek, handsome, docile and fast roadster built essentially of stock Ford and Mercury parts (brakes, steering, suspension, transmission) mounted on a special box-type chassis and equipped with an all-steel custom body of outstandingly good finish, welded into one rigid unit. You cannot, for instance, replace a dented fender. The job, as on most sports cars, is one for a panel beater. Yet the Thunderbird is not a true sports car of competition type, nor does Ford make any such claim for it. In advertising jargon it is a "personal" or "much preferred" car—by which is meant a sporting, second-string machine, redolent with snob appeal, highly photogenic and fun to drive on a weekend breeze or a trip to the golf links.

Finished in black, with black and cream leather upholstery, a black pile carpet and black mohair top, this particular Thunderbird heralded one of three color schemes which will include turquoise and Thunderbird red with matching leather. The comfortable seat (51� inches wide) is ample for two, but it took less than an afternoon's hard driving to discover that three abreast can easily become a crowd. For a tall driver, leg and headroom are at a premium (24� inches from seat edge to pedals with the seat fully back and three inches head clearance with the top up) but the telescopic steering wheel provides some compensation for the tight fit.

Against these minor drawbacks, the Thunderbird is a very appealing machine, judged even by sports-car standards. When top and windows are raised, it is as snugly weatherproof as a convertible and the longer you drive it the better you like it. Forward vision (through the curved panoramic windshield offering 1,027 square inches of glass) is superb. Both fenders are clearly in sight and the smoothly contoured hood airscoop confers a pleasant suggestion of power. Instrument grouping is identical with that on 1954 Fords, but with two extra dials of 3?-inch diameter, providing a 5,000 rpm tachometer at left and a sweep-second clock at right.

Shifting is by a centrally located chrome floor lever which slides backward or forward on a chrome scale calibrated with a conventional hydramatic dial. The knob has a push-button safety locking device which must be depressed to move from neutral through park to drive. With the accelerator jammed to the floor for a scat getaway, it is easy to spin the rear wheels, even on dry concrete. Under these conditions, the hydramatic upshifts to intermediate and high at the usual 30 and 65 mph, but a manual shift would do the Thunderbird far more justice. Still, the outstandingly good low-speed torque is obvious from the fact that the 0-30 and 30-50 mph acceleration times are identical.

SPEEDING AND CORNERING

Some fast driving and cornering quickly demonstrated the excellent roadability and handling qualities of the car, which has the best power steering I have ever sampled. It is light, positive and devoid of disconcerting "remoteness" and allows quick correction of deliberately induced slides. At 110 mph (4,300 rpm) the Thunderbird was quiet and rock-steady and could be steered with one hand, but stopping was another matter. The power brakes (11-inch Mercury drums with a 50% assist) put dangerously too much emphasis on power and too little on progressive braking. Tramping hard on the pedal produced a frightening one-second time lag, after which the wheels abruptly locked solid and the car slid with howling tires. This explains the mediocre stopping at speeds of 45 mph and up.

Flat out, the Thunderbird is capable of 128 mph (5,000 rpm) but this maximum is not recommended since the engine is revving way past peak. Just what that peak is, the otherwise cooperative Ford Technical Service Laboratory refuses to reveal, even at this writing which is within days of the car's general release. The V-8 engine uses a recast Mercury block bored out to 3.75 inches and with a 1.27-inch longer stroke. This block, incidentally, will probably form the basis of the 1955 Ford engine. A fair guesstimate of the Thunderbird's output on the basis of known specifications (see above) puts it at around 190 hp at 4,400 rpm.
