1973–1977
The 1973 oil crisis plagued the sales of high performance cars from manufacturers around the world; the rising price of oil caused governments to mandate new fuel economy laws, and consumers to seek smaller, more practical modes of transportation. Sales of Lamborghini's exotic sports cars, propelled by high-powered engines with little consideration for fuel efficiency, (the 1986 Countach, powered by a 5.2-litre evolution of the V12 engine, had a 6 mpg-US (39 L/100 km; 7.2 mpg-imp) city and 10 mpg-US (24 L/100 km; 12 mpg-imp) highway United States Environmental Protection Agency rating) suffered greatly.
In 1974, Ferruccio Lamborghini sold his remaining 49% stake in the company to René Leimer, a friend of Georges-Henri Rossetti. Having severed all connections with the cars that bore his name, he retired to an estate on the shores of Lake Trasimeno, in the frazione of Panicarola in Castiglione del Lago, a town in the province of Perugia in the Umbria region of central Italy, where he would remain until his last days.
In 1974, the LP500 finally entered production as the Countach, powered by a smaller, 4.0-litre V12. The first production model was delivered in 1974. In 1976, the Urraco P300 was revamped into the Silhouette, featuring a Targa top and a 3-litre V8. Its poor build quality, reliability, and ergonomics all worked against it, as did the fact that it could only be imported into the U.S. via the "grey market". Only 54 were produced. The Countach was also hampered by its lack of direct participation in the American market until the LP500 version, released in 1982.
1978–1986
As the years passed, Lamborghini's situation became even more dire; the company entered bankruptcy in 1978, and the Italian courts took control. They first appointed Dr. Alessandro Arteses to run the company's operations, but a year later, Raymond Noima and Hubert Hahne, who was Lamborghini’s German importer, were appointed to take over the running of the company. In 1980, the Swiss Mimran brothers (Jean-Claude and Patrick), famed food entrepreneurs with a passion for sports cars, were appointed to administer the company during its receivership. During administration, the automaker reworked the failed Silhouette into the Jalpa, which was powered by a 3.5-litre V8 that had been modified by former Maserati great, Giulio Alfieri. More successful than the Silhouette, the Jalpa came closer to achieving the goal of a more affordable, livable version of the Countach. The Countach was also updated, finally allowing it to be sold in the U.S. with the release of the LP500 model in 1982. By 1984, the company was officially in the hands of the Swiss. The Mimrans began a comprehensive restructuring program, injecting large amounts of capital into the floundering automaker. The Sant'Agata facilities were rehabilitated, and a worldwide hiring campaign to find new engineering and design talent began in earnest.
The immediate results of the investment were good. A Countach "Quattrovolve", producing a mighty 455 bhp, was released in 1984; the fumbling Cheetah project resulted in the release of the Lamborghini LM002 sport utility vehicle in 1986. However, despite the Mimrans' efforts, the investments proved insufficient to revive the company. Seeking a large, stable financial partner, the brothers met with representatives of one of America's "Big Three" automakers, the Chrysler Corporation.
1987–1993
In April 1987, in an acquisition spearheaded by Chrysler chairman Lee Iacocca, the American company took control of the Italian automaker, after paying out US$33 million to the Mimrans. According to Jolliffe, the Mimran brothers were the only owners of Lamborghini to ever make money out of the company, having sold it for many times the dollar amount they paid for it six years earlier.
At the time, Lamborghini was working on a successor to the Countach, the Diablo. The car's original design had been penned by Marcello Gandini, the veteran who had penned the exterior appearances of the Miura and the Countach while working for coachbuilder Bertone. However, Chrysler executives, unimpressed with Gandini's work, commissioned the American car-maker's own design team to execute a third extensive redesign of the car's body, smoothing out the trademark sharp edges and corners of Gandini's original design; the Italian was left famously unimpressed with the finished product. The Diablo had been intended for release in time for September 1988, when Lamborghini would celebrate its 25th anniversary; once it was clear that mark would be missed, a final version of the Countach was rushed into production instead. The Anniversary Countach was later acclaimed as the finest version of the car to be built.
By the end of 1987, Emile Novaro had returned from his long recovery, and used his authority to halt Chrysler's increasing interference in the development of the Diablo. Much to the chagrin of the Fighting Bull, Chrysler exhibited a four-door concept car at the Frankfurt Auto Show, badged as a 'Chrysler powered by Lamborghini'. The Portofino was poorly received by the motoring press and Lamborghini's employees alike, but went on to become the inspiration for the Dodge Intrepid sedan.
In April 1988, the Bertone Genesis, a Quattrovalvole V12-powered, Lamborghini-branded vehicle resembling a minivan was debuted at the Turin motor show. The unusual car, intended to gauge public reactions, was abandoned, a misfit in both Lamborghini's and Chrysler's product ranges. The Genesis had been commissioned alongside the new "baby Lambo" that would replace the Jalpa, occupying the then-empty space below the Diablo in Lamborghini's lineup. The project had been allocated a $25 million budget, with the prospect of selling more than 2,000 cars per year.
The Diablo was released to the public on January 21, 1990, at an event at the Hotel de Paris in Monte Carlo. The Diablo was the fastest car in production in the world at the time,[citation needed] and sales were so brisk that Lamborghini began to turn a profit. The company's U.S. presence had previously consisted of loosely affiliated and disorganized private dealer network; Chrysler established an efficient franchise with full service and spare parts support. The company also began to develop its V12 engines for powerboat racing. Profits increased past the $1 million mark in 1991, and Lamborghini enjoyed a positive era.
The uptick in fortunes was to be brief; in 1992, sales crashed, as the $239,000 Diablo proved ultimately to be unaccessible to American enthusiasts. With Lamborghini bleeding money, Chrysler decided that the automaker was no longer producing enough cars to justify its investment.
