The Mercury Grand Marquis of 1992-1997 is the aerodynamically restyled generation of Ford's rear-wheel-drive Panther platform, sold as a four-door pillared sedan in GS and LS trim. For 1992 it replaced the previous 5.0 liter (302 cubic inch) pushrod V8 with the 4.6 liter (281 cubic inch) modular SOHC V8 backed by a four-speed automatic overdrive transmission. It shared its chassis and drivetrain with the concurrently restyled Ford Crown Victoria, and the station wagon body (Colony Park) was dropped, leaving the sedan as the only body style.
Other Mercury Grand Marquis generations
Platform
The 1992-1997 Mercury Grand Marquis uses Ford's body-on-frame, rear-wheel-drive Panther platform, carried over from the earlier boxy Grand Marquis but reskinned for 1992 with rounded aerodynamic bodywork. It retained a live rear axle with coil springs and a live-axle Panther chassis rather than adopting a unibody. It is the Mercury counterpart to the 1992-1997 Ford Crown Victoria.
Engine lineup
Every 1992-1997 Grand Marquis uses the 4.6 liter (281 cubic inch) SOHC modular V8 with two valves per cylinder and sequential electronic fuel injection. This replaced the 5.0 liter (302 cubic inch) Windsor pushrod V8 used through 1991.
- Single exhaust: rated at 190 net horsepower.
- Dual exhaust option: rated at approximately 210 net horsepower.
The dual-exhaust package was offered as an option and produces the higher output figure; the single-exhaust rating of 190 horsepower is the standard configuration across the span.
Transmission
The 4.6 V8 drives through a four-speed automatic overdrive transmission. Early 1992 cars used the AOD-E (electronically controlled), and the revised 4R70W four-speed automatic was adopted during this generation. All are four-speed automatics driving the rear wheels.
Body styles
The 1992-1997 Grand Marquis was built only as a four-door pillared (framed-window) sedan. The Colony Park station wagon that had been part of the prior Grand Marquis range was discontinued and did not return for the aero generation.
Trims and variants
- GS: the base trim.
- LS: the higher trim with additional equipment.

Asked all the time
What engine does the 1992-1997 Grand Marquis use?
All 1992-1997 Mercury Grand Marquis models use the 4.6 liter (281 cubic inch) SOHC modular V8 with sequential fuel injection. It replaced the earlier 5.0 liter (302 cubic inch) pushrod V8. Standard single-exhaust cars are rated at 190 net horsepower, and the optional dual-exhaust setup raises output to 210 horsepower.
What transmission is behind the 4.6 V8?
A four-speed automatic overdrive. Early 1992 cars used the hydraulic AOD, replaced partway through 1992 by the electronic AOD-E (used through 1994); the heavier-duty 4R70W four-speed arrived for 1995 and ran through 1997. All drive the rear wheels.
Was there a Grand Marquis wagon in this generation?
No. The 1992-1997 Grand Marquis was offered only as a four-door pillared sedan. The Colony Park station wagon from the previous Grand Marquis range was discontinued and did not return with the aero restyle.
How does the Grand Marquis differ from the Ford Crown Victoria of the same years?
They share the Panther platform, the 4.6 liter SOHC V8, and the four-speed automatic. The Grand Marquis is the Mercury version, distinguished mainly by front and rear styling, trim, and equipment. The 1992-1997 Crown Victoria is the Ford counterpart.
What trims were available?
Two: the base GS and the higher-content LS. Both use the same 4.6 liter V8 and four-speed automatic.
Which years should a buyer look for?
Buyers wanting the more powerful setup should seek cars equipped with the optional dual exhaust (210 horsepower versus 190). The 1995 and later cars use the heavier-duty 4R70W transmission and OBD-II, and 1995 also brought mid-cycle styling updates; 1997 is the last year before the 1998 redesign.
