The Ford Crown Victoria is a variety of automobile made by the Ford Motor Company and sold mainly in the North American market.

1955

The first "Crown Victoria" appeared in 1955; it was a 2-door 6-seater hardtop coupe, part of the Ford Fairlane range, that differed from the regular Victoria model (named after a type of carriage) by having a lower, sleeker roofline and much more stainless steel trim, including a stainless steel band that 'crowned' the roofline, passing right over the car, as an extension of the B-pillar line. That model did not outlast the 1950s.

1979

In 1979, Ford brought back the name on a deluxe version of the LTD full-size car line on the Ford Panther platform. It was recognizeable by its four headlights with amber turn signals beneath them (base LTDs had two headlights, and clear turn signals in the grille). There was a 2-door coupe (all steel top this time), 4 door sedan and a wagon- the wagon became a "Country Squire" if fake-wood trim was ordered. Most had 5.0 L Windsor V8s, all had automatics.

The 1979 to 1991.5 models are known as "box body" cars because of the squared-off exterior styling. These cars still use the same type of twin-tube shock absorbers found on 60s and 70s cars:

• The front shocks are used on 1971-1996 Chevrolet Impala/Caprice/Bel-Air and 1985-2005 Chevrolet Astro 2WD.
• The rear shocks are used on 1968-1969 Chevrolet Camaros with the multi-leaf rear springs and 1968-1969 Pontiac Firebirds.

1992

Post-1992 Ford Crown Victoria

In 1992, along with dropping the LTD designation, the sedan body (production of the station wagon having ceased in 1991) was completely redesigned to the round, six-window shape (which shared many details with its contemporary, the newly refreshed 1992 Taurus), and there was a new 4.6 L modular engine. There was a further facelift in 1998 and chassis modifications for 2002.

The 1991.5 through 1997 cars are known as "aero Vics" because of their aerodynamic styling and lightweight bodies. The final two model years are regarded as the best Panthers to date due to the interior quality/trim/fit and finish, low coefficient of drag, and lightweight body. The Romeo-built 4.6 L engine with updated Non-Performance Improved cylinder heads, camshafts, and intake manifold make the best platform for performance modifications.

This car, its slightly more luxurious twin the Mercury Grand Marquis, and the more expensive Lincoln Town Car are just about the only mass-produced passenger cars left in the world with body-on-frame construction, as opposed to the more modern "unibody" contruction style where the body panels are load bearing members. Mercury introduced a performance version called the Mercury Marauder but sales were slow.

Some 90% of police cars in the US and Canada are Crown Victorias, since Ford was the only automaker still making sedans for police after the Chevrolet Caprice was phased out after 1996. Current and former police versions (the latter are often used as taxis) handily outnumber civilian models. The Crown Victoria is usually referred to as the Dodge Monaco of the 1990s and beyond; before 1978, Chrysler owned the police/taxi/fleet market. The law enforcement version of the Crown Victoria is known as the Police Interceptor, and many taxi companies use this "heavy duty" version as well.

While the car has a been highly rated for safety, there was some controversy and lawsuits in the 1990s over the car's gas tank leaking after certain types of high energy crashes. Factors included the retention of the gas tank in the once-industry-standard position of behind the rear axle, rather than the now more common location of in front of the rear axle, the nature of the gas tank, and the unique circumstances of the car crashes. The condition may have been exacerbated by the positioning of a sharp bolt on the rear axle, which would puncture the tank in certain types of accidents. This might be similar to the Ford Pinto fuel tank controversy back in the 1970s using a similar construction style.

Ford has offered an upgrade kit to owners of Crown Victoria, Town Car and Grand Marquis cars to reduce the chance of the problem occurring. (See also Automotive Recall )

1998-2002

In 1998, the Crown Victoria's exterior styling, rear suspension, and ignition system were updated. The 1998-2002 "Crown Vics" have a revised 4-link rear suspension with a Watt's linkage . The general road handling manners have improved, but towing capacity has been officially reduced. The Crown Victoria also uses a coil-on-plug ignition design rather than traditional spark plug wires. This design was later implemented on other users of the Modular V8, including the 1999-up Mustang GT, and many F/E-series trucks.

The 1998 through 2002 models actually use the 1996-1997 Grand Marquis bodies with two slight differences:

• The front sidemarkers on the Crown Vics are flipped upside down
• Different tail lamps are fitted

2003-present

In 2003, the chassis was again redone with hydroformed steel. The front and rear suspension has also been completely overhauled. New inverted monotube shocks are now used (replacing the old twin-tube shocks that had been around since the 1960s). In front, new aluminum control arms, and rack and pinion steering (replacing the recirculating ball units) have been implemented. The rear suspension was redone for durability in police-duty applications and the rear shocks were moved outboard of the frame rails for better handling and ease of maintenance. As a result, the road-handling manners of the Panther platform cars have improved significantly.

The engine output increased due to the addition of a knock sensor for more aggressive timing.

The Crown Victoria retained the same exterior styling, but 2005 models now receive a rear whip radio antenna rather than an integrated rear defroster antenna.

Even with the latest 2005 Crown Vic, the overall design remains "relatively" unchanged from the 1979 design. It is still front independent suspension with a rear live axle on a body-on-frame design, using a traditional rear wheel drive drivetrain. Although dated, the design has worked well with police departments, livery cab companies, and the aged buyer target audience. It is considerably more durable than "modern" front wheel drive cars that rely on constant velocity joints for transmission of power to the steering wheels.

2004-up Police Interceptor

The 2004-2005 Police Interceptors (referred to many as CVPIs, P71s) are rated for 250 hp (186 kW) because of the addition of a new air intake system. This includes a new air box that resembles the Mercury Marauder airbox (raised airbox lid, deeper bottom) with an integrated 80mm mass air flow (MAF) sensor that is part of the airbox lid. This allows for much more precise flow calibration and reduces the chances of air leakage. A straighter zip tube (the flexible rubber hose between the throttle body and MAF outlet) is also used to reduce NVH (Noise, Vibration, and Harshness) as well as transfer air from the airbox to the throttle body with minimal flow resistance.

There were some problems with early 2003 Police Interceptors. The steel wheels would rust and fall out, the rack and pinion units would fail early on (sub-10k miles), and the axles would wear out and possibly fall out as well. This was not limited to the Crown Victoria Police Interceptor. Some 2003 Mercury Marauders were also affected. Luckily, this was only for very early 2003 models as the problems appear to have been fixed for newer models.

Future

Ford was rumored to be considering replacing the aging Panther platform with the front or all-wheel drive platform based on the D3 architecture. Ford has denied this.
