UPS to Test Hydraulic Hybrid Vehicles

In partnership with the US Environmental Protection Agency, UPS will begin testing a small fleet of hydraulic hybrid delivery trucks in the United States. The new vehicles can achieve 50-70% better fuel economy, a 40% reduction in greenhouse gas emissions, and pay for their extra expense in less than 3 years.

In a series hydraulic hybrid, the conventional drivetrain is replaced with a hydraulic system that stores energy by compressing gas in a chamber using hydraulic fluid. It works in much the same way that a hybrid electric car does — a small, efficient motor generates power which gets stored for later use — only, the way energy is stored in a hydraulic hybrid is in a pressurized chamber rather than in a battery.
