1989 Jaguar XJS Coupe
Fuel Economy Overview
The 1989 Jaguar XJS Coupe achieves an EPA-estimated 13 MPG in combined city and highway driving, with 11 MPG in the city and 16 MPG on the highway. Powered by a 5.3L 12-cylinder engine paired with a automatic 3-spd, this subcompact cars features Rear-Wheel Drive drive.
In terms of environmental impact, the 1989 XJS Coupe produces approximately 684 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 XJS Coupe has higher-than-average emissions in this regard.
The estimated annual fuel cost for this vehicle is $4,600, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $12,250 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.

Personalized Commute CalculatorEPA defaults to 55% City / 45% Hwy
Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
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.

Recall Intelligence
THE NORMAL LOCKUP FUNCTION OF THE AUTOMATIC (PASSIVE) BELT REEL CAN CAUSE THE BELT MOTOR WINCH ASSEMBLY TO LOCKUP SUCH THAT THE PASSIVE BELT SYSTEM WILL NOT DEPLOY/FUNCTION OR GETS STUCK AT VARIOUS POINTS ALONG THE TRACK CAUSING THE KINKING OR BREAKING OF ITS CABLE OR DETACHMENT OF THE TONGUE.
Consequence & Remedy
Consequence: IF THIS OCCURS THE OCCUPANTS OF THE VEHICLE CANNOT USETHE SAFETY BELTS, INCREASING THE RISK OF INJURY IN THE EVENT OF A SUDDEN STOPOR ACCIDENT.
Remedy: JAGUAR WILL REPAIR THE PASSIVE BELT SYSTEM IF THIS PROBLEM OCCURS OR HAS OCCURRED. JAGUAR WILL NOTIFY OWNERS OF THE EXISTENCE OF A LIFETIME WARRANTY ON COMPONENTS OF THE AUTOMATIC (PASSIVE) BELT SYSTEM.
THE HIGH TENSION LEAD FROM THE IGNITION COIL CAN MOVE FROM THE PRODUCTION LOCATION CLOSER TO THE #4A FUEL INJECTOR HOSE. THIS COULD LEAD TO THE OUTER AND INNER INJECTOR HOSES CRACKING OR SPLITTING FROM OZONE DETERIORATION.
Consequence & Remedy
Consequence: SPLITTING OF THE INJECTOR HOSES WOULD CAUSE EXPULSION OFFUEL IN THE ENGINE COMPARTMENT AND RESULT IN A FIRE WHEN EXPOSED TO A SOURCE OFIGNITION.
Remedy: REPLACE THE HIGH TENSION LEADS WITH SHORTER HIGH TENSION LEADS. REPLACE BOTH THE FUEL INJECTOR AND THE #4A FUEL INJECTOR HOSE AS NECESSARY.
EXCESSIVE FUEL VAPOR PRESSURE CAN OCCUR THAT, AFTER PROLONGED CYCLING, COULD WEAKEN THE FUEL TANK STRUCTURE.
Consequence & Remedy
Consequence: THIS CAN CAUSE FUEL TANK LEAKS WHICH, IN THE PRESENCE OFAN IGNITION SOURCE, COULD RESULT IN A VEHICLE FIRE.
Remedy: INSTALL A REVISED FUEL PURGE SYSTEM WHICH ELIMINATES EXCESSIVE VAPOR PRESSURE BUILD-UP.
ELECTRONICALLY CONTROLLED VALVES IN THE CRUISE CONTROL ACTUATOR MAY NOT FUNCTION PROPERLY DUE TO DIRT ENTERING THE VALVES.
Consequence & Remedy
Consequence: CRUISE CONTROL WOULD NOT DISENGAGE UNDER NORMAL OPERATINGCONDITIONS WHICH COULD RESULT IN LOSS OF CONTROL AND AN ACCIDENT.
Remedy: REPLACE CRUISE CONTROL ACTUATOR AND INSTALL ADDITIONAL VACUUM DUMP VALVE.
