Does Air Suspension Affect Fuel Economy?

Yes, air suspension affects fuel economy, usually with a slightly negative impact compared to traditional steel springs, but the impact is usually small and depends on the specific situation.

1. Added weight

Air suspension systems contain heavy components such as air compressors, air tanks/dryers, valves, and reinforced air lines.

This additional weight (typically 50-100+ lbs / 25-45+ kg) increases the total mass of the vehicle.

Impact: The added mass requires more energy (fuel) to accelerate and maintain speed, which slightly reduces fuel economy.

2. Power consumption (compressor)

The compressor runs on electricity from the alternator, which is driven by the engine.

Whenever the compressor is operating (such as to adjust ride height, inflate air bags after parking, maintain pressure, or compensate for slow leaks), it places additional load on the engine.

Impact: This parasitic load slightly increases fuel consumption during the time the compressor is operating. This effect is exacerbated by frequent adjustments (e.g. on very rough roads) or by frequent compressor cycling due to leaks.

3. Aerodynamic Advantages (Potential Positive Impact)

Some advanced air suspension systems allow the vehicle to be automatically lowered at highway speeds.

Impact: A lower ride height significantly reduces air drag. This can improve highway fuel economy and may offset some of the weight and compressor penalties in certain driving conditions. This is more common in high-performance/luxury models equipped with this feature.

4. Maintenance and Efficiency

Air system leaks are a common point of failure. A leaky system forces the compressor to run more frequently to maintain pressure.

Impact: A system with leaks can significantly increase compressor run time, with a more noticeable negative impact on fuel economy due to the constant parasitic load. Proper maintenance is critical.
