Engine Options:
The Polaris Centurion typically featured AMC (American Motors Corporation) engines. Specific displacement and configuration would depend on the exact model variant and year, but common options for AMC inline-6 and V8 engines are likely candidates. For instance, a 4.2L (258 cu in) inline-6 or a 5.0L (304 cu in) V8 are plausible.
Horsepower Range:
Horsepower figures would vary by engine, but typically ranged from 100-150 HP for inline-6 and 120-170 HP for V8s of this era. Exact figures are within the manual.
Torque Range:
Torque specifications would align with the engine displacement and configuration, crucial for understanding towing and acceleration capabilities. Manual will detail specific torque ratings.
Fuel Delivery:
Likely carburetor-based fuel delivery systems, potentially Rochester Quadrajet or similar for V8s, and simpler carburetors for inline-6. Fuel injection was less common in this vehicle segment for these years.
Ignition Type:
Conventional breaker point ignition or early electronic ignition systems.
Standard Transmission:
Likely a 3-speed automatic transmission (e.g., Chrysler TorqueFlite A727 or similar AMC-derived automatic) as standard for many trims.
Optional Transmission:
A manual transmission option, potentially a 3-speed or 4-speed manual, might have been available, especially on lower trims or specific configurations.
Driveline:
Rear-wheel drive (RWD) configuration is standard for the Polaris Centurion. 4x4 options might exist depending on specific sub-models or packages.
Automatic Transmission Fluid:
Specific ATF type (e.g., Dexron-II or equivalent) will be detailed in the manual for the installed automatic transmission.
Body Styles:
The Polaris Centurion was primarily offered as a full-size sedan and possibly a station wagon variant. Convertible or coupe options are less likely for this specific model name from Polaris.
Wheelbase:
Wheelbase would be consistent with a full-size AMC platform of the era, likely in the range of 110-118 inches. Precise figures available in manual.
Curb Weight:
Curb weight would typically range from 3,500 to 4,200 lbs depending on body style and engine/options. Exact specifications will be in the manual.
Crash Test Data:
No modern standardized crash test data (NHTSA, IIHS) is available for vehicles of this vintage. Safety features would reflect the standards of the late 70s/early 80s.
Braking System Type:
Front disc brakes and rear drum brakes were standard for this era. Power assist was common.
Seat Belts:
Lap and shoulder belts would be standard, along with standard 3-point seat belts for front occupants.
Steering Column:
Collapsible steering column was a common safety feature introduced in this period.
Audio System:
Basic AM/FM radio, potentially with an 8-track player or cassette deck as an optional upgrade. Manual will cover speaker replacement and basic radio troubleshooting.
Air Conditioning:
Optional factory-installed air conditioning systems were available. Manual will cover AC system service and troubleshooting.
Cruise Control:
Cruise control was an available option on higher trim levels. Manual will include diagnostic and repair procedures for this system.
Connectivity Features:
No modern connectivity features like Bluetooth or USB were available. Focus is on mechanical and electrical systems.
Oil Change Interval:
Typically every 3,000 to 5,000 miles or 6 months, depending on driving conditions. The manual will provide precise intervals and oil viscosity recommendations.
Tune Up Interval:
Recommended tune-ups, including spark plug replacement, ignition timing adjustment, and filter changes, would be around 15,000 to 30,000 miles. Manual will detail specific intervals for components.
Transmission Service Interval:
Automatic transmission fluid and filter changes typically recommended every 24,000 to 30,000 miles or as per manual's guidance.
Engine Oil Specification:
Likely SAE 10W-30 or 10W-40, depending on climate. Specific API service classification will be in the manual (e.g., API SF or SG).
Coolant Specification:
Ethylene glycol-based antifreeze mixed with distilled water (50/50 ratio). Manual will specify type and capacity.
Brake Fluid Specification:
DOT 3 brake fluid is a common standard for vehicles of this era. Manual will confirm specification.
Common Wear Items:
Typical issues for vehicles of this age include carburetor issues, aging electrical components, exhaust system rust, suspension wear, and potential cooling system leaks. The manual's troubleshooting section will address these.
Body Rust:
Corrosion and rust, particularly in wheel wells, rocker panels, and chassis components, are common concerns for vehicles of this vintage. The manual will offer guidance on inspection and repair.
Polaris Automotive History:
Polaris primarily known for off-road vehicles and snowmobiles. Their foray into the automotive market in the late 1970s and early 1980s, utilizing AMC platforms, was a relatively brief but notable period. The Centurion represents one of these limited automotive offerings.
Centurion Development:
The Polaris Centurion was based on AMC's full-size platform, likely the AMC Matador or Concord lineage, rebadged and marketed by Polaris. This allowed for a quicker market entry using existing chassis and drivetrains.
Production Period:
1979-1981
Manufacturing Location:
Likely manufactured in facilities associated with AMC or reassembly plants contracted by Polaris.
Industry Awards:
Information on specific industry awards or accolades for the Polaris Centurion is scarce. Its market presence was limited, and it was more of a niche offering in the automotive landscape.
Consumer Reviews Era:
Consumer reviews from the period would have focused on comfort, ride quality, and the reliability of the AMC-sourced components. The manual indirectly reflects the original design and intended performance.
