In terms of environmental impact, the 1998 Sonoma 4WD produces approximately 555 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 Sonoma 4WD has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,750, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $8,000 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.

The Brick Effect: Highway Speed Penalty

EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Because the Standard Pickup Trucks 4WD has a large frontal area, expect your real-world highway fuel economy to drop by up to 25% at high speeds.

VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND MULTI-PURPOSE PASSENGER VEHICLES. A FATIGUE FRACTURE OF THE REAR AXLE RIGHT-HAND BRAKE PIPE CAN OCCUR CAUSING A SLOW BRAKE FLUID LEAK RESULTING IN A SOFT BRAKE PEDAL. IF THE BRAKE PIPE BREAKS, THE DRIVER WOULD EXPERIENCE A SUDDEN DROP IN THE BRAKE PEDAL, THE INSTRUMENT PANEL BRAKE LIGHT WOULD ILLUMINATE, AND THERE WOULD BE A LOSS OF REAR BRAKE PERFORMANCE.

Consequence & Remedy

Consequence: PARTIAL LOSS OF BRAKING AT A TIME WHEN MINIMUM STOPPING DISTANCE WAS REQUIRED COULD RESULT IN A VEHICLE CRASH.

Remedy: DEALERS WILL INSPECT AND REPLACE THE BRAKE PIPE.
