Zimmer QuickSilver

Zimmer's second model and its only modern one: a two-seat, mid-engined luxury coupé on a stretched Pontiac Fiero, designed by Don Johnson and built at Pompano Beach from 1986 to 1988. The maker wrote QuickSilver; the press and most searches write Quicksilver.

In February 1986, at the dealers' convention in New Orleans, Zimmer Motor Cars showed its dealers something they had not seen from it before: a low two-seat coupé with its engine behind the seats, built on a new Pontiac Fiero. After more than five years of the 1930s look of the Golden Spirit, the QuickSilver was a modern design, and Collectible Automobile, looking back in 1993, called it "The First 'Neo-Modern'". Its designer was D. A. "Don" Johnson, a former General Motors designer, not the actor.⁠1​2​3

Origin

Collectible Automobile dates the start of the work to 1983. Johnson drew the car, and his signature, D. A. Johnson, is on its door-sill plate; Zimmer's literature, as Collectible Automobile quoted it, presented it as "a designer original", created "by the skillful hand of former General Motors designer, Don Johnson", which offered "an alternative to 'look alike' two-seaters". The company saw it as the first American car in a new class of two-seat personal luxury cars, and launched it with high words.

This new model promises to match the class and distinction that permeates the lifestyle of its buyer, … Designed to be elegant, contemporary, and American in character, the QuickSilver may very well set the standard in this new automobile frontier.

Robert P. Zimmer, 1986, as quoted in Collectible Automobile, August 1993⁠2​3​4

How it was built

Zimmer bought new black Fieros, stripped them and threw away their plastic body panels. The Fiero's steel space frame was lengthened by 406 mm (16 in) behind the front suspension, "all in front of the door", as Popular Mechanics put it, and by 330 mm (13 in) behind the rear wheels; the radiator and air-conditioning lines and the steering column were lengthened with it. A hand-laid fibreglass body went on, with heavy chrome bumpers that Car and Driver reported were formed in Taiwan and chromed in Florida. The Fiero's manual steering gave way to a power-assisted rack from a Merkur, and the rear got a very stiff anti-roll bar; the rest of the suspension was the Fiero's. A window sticker of 1986 still recorded the car as originally certified by General Motors, with its engine and gearbox (transmission).

The QuickSilvers were built in the Pompano Beach plant on a line beside the Golden Spirit's. The dash wood came from an outside supplier, and the leather trim was done upstairs in the plant. Robert Zimmer spoke of 500 hours of work in 1986, and a company release of 1988, as Collectible Automobile quoted it, of "nearly 650 man/hours"; and Car and Driver reckoned the conversion added about 200 kg (440 lb). The 1987 release promised "six coats of hand-rubbed paint"; a later brochure describes a two-step base-coat and clear-coat finish. The specification below gives the engine, gearbox and dimensions.⁠3​2​10​11​12​4​6

Equipment and colours

The window sticker of a car sold in 1986 lists as standard air conditioning, cruise control, a rear-window demister (defroster), power windows, door locks and aerial, electric mirrors, retracting halogen headlamps with cornering lamps, Italian leather throughout, reclining bucket seats, English wood dash panels, a leather-wrapped steering wheel, carpeted luggage compartments at both ends, a tool kit and a tailored car cover, on chrome-plated wire wheels with stainless spokes. The 1987 release added a stereo with a five-band graphic equaliser.

In 1986 the car came in black or red, with ivory, red or grey inside. For 1987 the release lists red, black, silver and white, with red, pewter or cameo interiors, and a later brochure the same four outside, with "special color and trim" by arrangement.

We like to think of QuickSilver as a modern, coach-built version of the two-seat Thunderbird. The car has that special kind of appeal because of its style, extensive use of chrome, wire wheels, and white sidewall tires,

The XTZ

Zimmer showed the XTZ at the Greater Los Angeles Auto Show, which opened on 3 January 1987. It was a monochrome car in the "California look": six coats of "ecstasy white" base coat and clear coat, matching aluminium wheels, Goodyear Eagle GT tyres and a special handling package, and inside "ecstasy white" Italian leather on the seats, console, instrument and door panels, with a black headlining, piping and carpets. The release said it "will begin limited production in 1987, and although available to dealers nationwide, was designed with the west coast automobile enthusiast in mind". The car was shown, so at least one was built; how many followed, no source read says.⁠4

Contents

The Performance Model

In October 1987, by Collectible Automobile's account, Zimmer announced a Performance Model at the standard car's price, with a modified front suspension, Bilstein gas dampers, Riken alloy wheels and Goodyear Eagle GT tyres in two sizes, the wider at the back. A later brochure offers the same thing as a "performance handling package at no extra charge", for the driver "who prefers more sporting response", with the Riken wheels in gold, silver or satin black to suit the body colour. How many cars had it, no source read says.⁠2​11

Production

Robert Zimmer announced plans for 300 QuickSilvers in 1986 and 1,000 in 1987. Sales, Collectible Automobile wrote, "never approached" those predictions: by September 1986 about 12 had been sold, and in April 1987 Carl Severe told Popular Mechanics that "only about 110 will be built each year". The production readings below give the company's own figure of 1988 and the revival company's later, higher figure, for which no period source was found; How Many Zimmers Were Made weighs them against the cars' own production numbers.⁠5​2​1​10​14

Contents

What the press said

Car and Driver made the QuickSilver its cover story in April 1987. Patrick Bedard's test, with "Counterpoint" comments from Arthur St. Antoine, Csaba Csere and Don Sherman, found the car heavier and slower than Zimmer claimed. The specification below shows the magazine's measured figures, with Zimmer's claims in the note behind each asterisk; no test by Zimmer itself has been found, and its later brochure gave a weight close to the magazine's. Bedard still liked the way it drove: "The car simply doesn't feel like a Fiero." Popular Mechanics the same month saw in its "all new fiberglass shapes" a blend of "many of the newer luxury coupes like Toronado, Mark VII and LeBaron", with performance "excellent, though not in the class with some true sports models". Car and Driver's is the only full road test of either Zimmer found, and the reviews gather the rest.⁠3​4​11​10​6

Contents

The end, and before and after

The Fiero ended with the 1988 model year, and with it Zimmer's supply of donors; the QuickSilver ended with the company, when Zimmer Corporation filed for Chapter 11 on 10 May 1988 and the Pompano Beach plant closed. It had no predecessor: it was Zimmer's second and last model. It had no successor either. Art Zimmer's revival company of 1997 built only Golden Spirits, and its parts depot stated plainly: "No Quicksilver parts are available."

No source read records a version for other markets; the company's claims of sales abroad are in the history's other markets section. The press of 1986 set the car against the coming Cadillac Allanté and Chrysler's two-seater built with Maserati, and Zimmer itself against the two-seat Thunderbird; Neoclassic Car Brands compares them.⁠2​7​8​14​6​4​10
