Because UEVs have limited top speeds, they cannot be tested by some EVAmerica test procedures. Specifically, UEVs cannot attain the preferred 65-mph top speed required for dynamometer testing.

A new set of EVAmerica performance goals has been developed for UEVs because their limited top speeds require a different set of performance characteristics. Some of the UEV performance goals include acceleration time of 0 to 30 mph within 8.5 seconds, a minimum top speed of 45 mph within 1 mile, and a minimum range of 30 miles when tested on a dynamometer using the Urban Drive Cycle.

The Advanced Vehicle Testing Activity has started baseline performance, accelerated reliability, and fleet testing of UEVs.
