Ford Sierra

The Ford Sierra is a large family car built by Ford Europe from 1982 until 1993. It was designed by Uwe Bahnsen, Robert Lutz and Patrick le Quément. The code used during development was "Project Toni".

Released on 21 September 1982, it replaced the Ford Cortina and Ford Taunus. Its aerodynamic styling was ahead of its time but many conservative buyers did not take fondly to the styling.

Possibly for this reason (and the fact that the smaller Escort was enjoying an increase in sales during the early 1980s), and the early lack of a saloon variant, it never quite achieved the sales volumes of the Cortina or the Taunus, although sales were still strong; a total of 2,700,500 Sierras were made,[citation needed] mainly manufactured in Germany, Belgium, and the United Kingdom, although Sierras were also assembled in Argentina, Venezuela, South Africa, and New Zealand.

Styling

The first Ford vehicle to have the bold new "aero" look styling was the 1981 Ford Probe III concept car. The good reception this received encouraged Ford management to go ahead with a production car with styling almost as challenging. This "aero" look influenced Fords worldwide; the 1983 Ford Thunderbird in North America introduced similar rounded, flowing lines, and some other new Fords of the time adopted the look. The aerodynamic features of the Sierra were developed from those first seen in the Escort Mark III — the "Aeroback" bootlid stump was proved to reduce the drag coefficient of the bodyshell significantly, which was a class leading 0.34 at its launch [1].

The aerodynamic styling of the Sierra would later be seen in North America's equally revolutionary Ford Taurus.

At first, many found the design blob-like and difficult to accept after being used to the sharp-edged, straight-line styling of the Cortina, and it picked up nicknames such as "Jellymould" and "The Salesman's Spaceship" (the latter thanks to its status as a popular fleet car in the United Kingdom). Sales were slow at first. It was later in the Sierra's life that the styling began to pay off; ten years after its introduction, the Sierra's styling was not nearly as outdated as its contemporaries, even though all major competitiors were newer designs, although the Sierra had been tweaked on several occasions. The most notable changes came at the start of 1987, with a major facelift the addition of a Sapphire saloon. As other manufacturers adopted similar aerodynamic styling, the Sierra looked more normal.
