Benefits of Fleet Testing

Improved System Reliability - Bathtub Curve Theory

• Zones of Reliability:
  • Infant failure: High initial failure rate that decreases quickly as defects in product and
    process are found and addressed.
  • Constant failure: Generally low and constant failure rate.
  • Wear out failure: Increasing failure rate as product ages and wear takes its toll.

High Mileage Fleets quickly identify these failures and expose emission system durability issues.
