Gross Vehicle Weight Rating:
Not explicitly stated but typical for a sporty coupe of this era.
Cargo Volume:
Limited due to coupe design, primarily for small items. Rear seats are typically foldable for slightly expanded space.
NHTSA Crash Tests:
Specific NHTSA ratings for this model year are not readily available. Vehicles of this era generally lacked advanced safety features.
Brakes:
Front: Ventilated Disc Brakes. Rear: Drum Brakes (standard). Optional: Rear Disc Brakes on higher trims or Turbo models.
ABS:
Anti-lock Braking System (ABS) was an optional feature, typically available on higher trim levels or Turbo models from 1987 onwards.
Seat Belts:
3-point front seat belts, 2-point rear seat belts.
Airbags:
Driver-side airbag was not standard equipment and was rarely offered or was an early, limited option on some later models within this range. Passenger airbags were not available.
Body Structure:
Reinforced safety cage construction with front and rear crumple zones, typical for 1980s vehicle safety standards.
Audio System:
Factory-installed AM/FM stereo radio with cassette player. Optional premium sound systems may have featured more speakers and graphic equalizers.

Manual climate control with rotary knobs for fan speed, temperature, and air direction. Air conditioning (A/C) was a common option.
Cruise Control:
Available as an option on many models.
Power Features:
Power windows, power door locks, and power mirrors were available on higher trim levels.
Connectivity Features:
No modern connectivity features such as Bluetooth or USB ports. Connectivity was limited to the audio system.
Oil Change:
Every 3,000 - 5,000 miles (4,800 - 8,000 km) or 6 months, whichever comes first.
Filter Replacement:
Oil filter with every oil change. Air filter every 15,000 - 30,000 miles (24,000 - 48,000 km). Fuel filter every 30,000 - 50,000 miles (48,000 - 80,000 km).
Timing Belt:
Crucial: The 2.6L SOHC engine uses a timing belt. Replacement is critical every 60,000 - 90,000 miles (96,000 - 145,000 km) or as per manual recommendation. Belt failure can cause catastrophic engine damage.
Engine Oil:
API SG or higher, SAE 10W-30 or 10W-40.
Coolant:
Ethylene Glycol-based antifreeze (green) mixed 50/50 with distilled water. Capacity approximately 7.5 quarts (7.1 liters).
Brake Fluid:
DOT 3 brake fluid.
Engine Problems:
Timing belt wear, oil leaks from valve cover gasket and rear main seal, potential for carburetor or fuel injection issues on older models, turbocharger issues on equipped models (e.g., wastegate actuator, oil feed).
Electrical Problems:
Aging wiring harnesses can lead to intermittent electrical faults, corrosion in connectors, issues with the alternator, starter, and power window regulators.
Suspension Steering:
Worn ball joints, tie rod ends, and bushings can lead to steering looseness and uneven tire wear. Power steering pump leaks.
Rust Corrosion:
As with most vehicles of this age, rust can be a significant issue, particularly in the rocker panels, wheel arches, and underbody.

Fuel Filter Example:
Fram G3, Wix WF8010, or equivalent.
Chrysler Strategy:
Chrysler's strategy in the 1980s involved badge engineering and partnerships, particularly with Mitsubishi, to fill gaps in their product line and offer more diverse vehicle types, including sporty coupes like the Conquest.
Conquest Origin:
The Chrysler Conquest was introduced in 1984 and continued through 1989. It was based on the second-generation Mitsubishi Galant Lambda (also known as the Mitsubishi Sapporo in other markets).

1984-1989 (North American market)
Industry Awards:
The Chrysler Conquest itself did not receive specific major awards, but its donor platform, the Mitsubishi Galant Lambda, was recognized for its styling and engineering within its market segment.
Consumer Reports:
Consumer reports from the period often highlighted the Conquest's sporty styling and performance, but also noted common issues related to reliability and build quality typical of imported models that were rebadged.
Emissions Standards:
Met federal and state emissions standards applicable for the model years 1986-1989 in the US.
