Fuel Economy Overview

The 1986 Jaguar XJS 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 1986 XJS 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 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.

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

Campaign #90V123000·1990-12-24
critical
Component: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY

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.

Campaign #90V035000·1990-05-21
critical
Component: VEHICLE SPEED CONTROL

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.

Component: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL

EXCESSIVE FUEL VAPOR PRESSURE CAN OCCUR.

Consequence & Remedy

Consequence: THIS CREATES FUEL ODORS AND AFTER PROLONGED CYCLINGCOULD CAUSE WEAKENING OF THE FUEL TANK STRUCTURE, WHICH COULD RESULT IN FUELTANK LEAKS. IF A SOURCE OF IGNITION IS PRESENT, A FIRE COULD RESULT.

Remedy: INSTALL REVISED PURGE SYSTEM COMPONENTS.

ELECTRICAL WIRING HARNESS MAY HAVE BEEN INCORRECTLY INSTALLED AND COULD CAUSE A SHORT CIRCUIT.

Consequence & Remedy

Consequence: SHORT CIRCUIT COULD RESULT IN A ELECTRICAL FIRE.

Remedy: REROUTE HARNESS; IF CHAFED OR DAMAGED CONDITION WILL BE CORRECTED.
