About Ford Five Hundred

Ford Motor Company strengthened its vehicle safety technology capabilities and began development of a D186 Taurus replacement as part of its 1999 acquisition of Volvo Cars and addition to Premier Automotive Group. The Ford Prodigy concept car debuted in 2000. The Prodigy, a 72MPG diesel-electric hybrid conceived as part of the Partnership for a New Generation of Vehicles, would introduce much of the Five Hundred’s exterior appearance; it was also the first Ford to employ the horizontal “three-bar” grille (which made its production debut on the 2006 Ford Fusion).

The Ford Five Hundred went into production on July 12, 2004 at Chicago Assembly (the previous assembly location for the Ford Taurus) and was released to the public in September 2004.

The Ford Five Hundred/Mercury Montego were built using a quality control technique known as Total Vehicle Geometry (TVG).

Volvo’s TVG is mainly computer-based, providing designers, engineers, and suppliers access to all prototype data and results at all phases of the design process. With increasing participation and access, prototype parts’ fit and finish improved, reducing the time required for preliminary production vehicles, sometimes known as pilot vehicles.

The Ford Five Hundred rides on the Ford D3 chassis, which is also used by the Mercury Montego and Ford Freestyle. The platform marked the change to front-wheel drive in full-size Ford sedans; an electro-hydraulic Haldex all-wheel drive system (based on that used in the Volvo S80 and XC90) was offered in all variants of the Ford Five Hundred or Mercury Montego.

Along with Haldex AWD, several Volvo design elements were incorporated into the Five Hundred’s structure, including a modified version of Volvo’s Side Impact Protection System (SIPS), which channels impact forces around the passenger compartment; the front frame rails were redesigned to better absorb impact forces.

In addition to the usual dual front airbags, the Five Hundred had the option of side and curtain airbags.

The Ford Five Hundred featured independent suspension for both front and back axles for the first time in a full-size Ford sedan, with MacPherson strut front suspension and a multi-link rear axle with coilover shocks; both axles were equipped with stabilizer bars.

The Five Hundred, like the Ford Crown Victoria, was equipped with four-wheel anti-lock disc brakes (12.5-inch front, 13-inch rear).

The Ford Five Hundred/Mercury Montego were powered by the same engine as the Ford Taurus: a 203 horsepower 3.0L Duratec V6, mated to a 6-speed Aisin automatic transmission (for front-wheel drive models) or a ZF CVT (for AWD).
