Three goals are to be meet before any ESS engine related performance product is released for sale :

1. Extended computerized load dyno test which simulates driving so hard that it is just not possible to drive this hard in real life.
2. Development cars through a 50000 mile (80000km) long term test which involves track driving, extreme heat and cold testing, high-speed Autobahn driving for extended periods, and normal everyday driving.
3. Car must have factory like or better drive-ability and smoothness and it must develop the extra power in a perfectly balanced manner.
