Fuel Economy Overview

The 1991 Dodge Dynasty achieves an EPA-estimated 20 MPG in combined city and highway driving, with 18 MPG in the city and 24 MPG on the highway. Powered by a 3L 6-cylinder engine paired with a automatic 4-spd, this midsize cars features Front-Wheel Drive drive.

In terms of environmental impact, the 1991 Dynasty produces approximately 444 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Dynasty has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,000, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $4,250 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Aerodynamic Speed Penalty

EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

moderate

Component: SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

THE ABS HYDRAULIC CONTROL UNIT CAN EXPERIENCE EXCESSIVE BRAKE ACTUATOR PISTON SEAL WEAR CAUSING PUMP-MOTOR DETERIORATION.

Consequence & Remedy

Consequence: IF THIS CONDITION OCCURS, THE ABS FUNCTION COULD BE LOST AND REDUCED POWER ASSIST WOULD BE EXPERIENCED DURING VEHICLE BRAKING INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.

Remedy: DEALERS WILL TEST THE VEHICLE'S ANTI-LOCK BRAKE SYSTEM AND REPAIR THE VEHICLES IF NECESSARY. ALSO THE WARRANTY ON ALL ABS COMPONENTS WILL BE EXTENDED TO 10 YEARS OR 100,000 MILES (EXCEPT FOR THE BRAKE ACTUATOR PISTON ASSEMBLY AND THE PUMP-MOTOR ASSEMBLY WHICH WILL HAVE A LIFETIME COVERAGE). OWNERS WILL ALSO BE REIMBURSED FOR PREVIOUS ABS COMPONENT REPAIR COSTS.

THE ANTI-LOCK BRAKE SYSTEM HIGH PRESSURE HOSE MAY LEAK OR DETACH AT ITS CRIMPED END FITTING RESULTING IN THE DISCHARGE OF HYDRAULIC FLUID.

Consequence & Remedy

Consequence: FLUID DISCHARGE EVENTUALLY CAUSES THE LOSS OF BOTH THEANTI-LOCK BRAKE SYSTEM AND HYDRAULIC ASSIST FOR THE BRAKE SYSTEM, RESULTING ININCREASED LIKELIHOOD OF BRAKE LOCKUP AND INCREASED STOPPING DISTANCES, WHICHCOULD RESULT IN A VEHICLE ACCIDENT.

Remedy: REPLACE THE ABS HIGH PRESSURE HOSE WITH A HOSE OF DIFFERENT DESIGN AND CONSTRUCTION.

Consequence & Remedy

Consequence: CORROSION OF THE RESISTOR TERMINALS INCREASES ELECTRICALRESISTANCE, LEADING TO OVERHEATING AND POSSBLE IGNITION OF THE WIRING CONNECTORSAND INSULATION, CAUSING A FIRE IN THE COWL AREA.

Remedy: THE BLOWER MOTOR RESISTOR BLOCK WILL BE REPLACED, AND A MASTIC PATCH APPLIED TO SEAL THE COWL AGAINST WATER ENTRY. DAMAGED WIRE CONNECTORS WILL BE REPLACED.
