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 405 Sedan 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.

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
A GRADUAL DETERIORATION OF THE HEADLIGHT PLASTIC LENS OCCURS.
Consequence & Remedy
Consequence: REDUCED LIGHTING FROM THE LENS CAN CAUSE VISIBILITY PROBLEMS INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT AND REPLACE BOTH FRONT HEADLIGHT ASSEMBLIES.
THE FUEL SUPPLY LINE CAN COME IN CONTACT WITH A HIGH VOLTAGE IGNITION LEAD IN THE ENGINE COMPARTMENT, CAUSING DETERIORATION OF THE FUEL LINE OVER TIME. THE DETERIORATION OF THE FUEL LINE COULD RESULT IN A FUEL LEAK IN THE ENGINE COMPARTMENT.
Consequence & Remedy
Consequence: FUEL LEAKED IN THE ENGINE COMPARTMENT COULD RESULT IN A FIRE IF EXPOSED TO A SOURCE OF IGNITION.
Remedy: DEALERS WILL REPLACE THREE FUEL LINES, CLAMPS AND MOUNTING CLIPS IN THE ENGINE COMPARTMENT AND REROUTE THE FUEL SUPPLY SYSTEM TO AVOID CONTACT WITH THE HIGH VOLTAGE IGNITION LEAD.
THERE MAY BE ELECTRICAL INTERFERENCE BETWEEN PASSIVE BELT MOTOR AND ELECTRONIC CONTROL UNIT.
Consequence & Remedy
Consequence: PASSIVE BELT SYSTEM MAY NOT OPERATE CORRECTLY AT ALLTIMES WHICH COULD CAUSE MORE SERIOUS INJURIES TO THE WEARER OF THE BELT.
Remedy: REPAIR PASSIVE BELT SYSTEM TO ASSURE PROPER OPERATION.
FUEL LEAKAGE EXCEEDS THE REQUIREMENTS OF FMVSS 301 IN A REAR BARRIER CRASH.
Consequence & Remedy
Consequence: VEHICLES WOULD NOT COMPLY WITH FMVSS 301.
Remedy: INSTALL PROTECTIVE BUFFERS; RELOCATE FUEL PUMP AND FILER TO ASSURE COMPLIANCE.
