A velocidades muito baixas o Leaf tem um pior desempenho...e esta hein? :)

"Like many other Leaf owners in the US, I had my car in a "End Dependence" Day parade today. I cleared the onboard counter and prepared to see some double digit miles per kWh numbers. I was expecting the miles of slow driving to boost my efficiency through the roof. I was wrong.

Most of the parade was a steady 3-4 MPH which was just right for keeping my foot off the peddles. This creep speed was the same in D or ECO. When the parade ended, my miles per kilowatt rating was 1.8. This is worse than driving at 55MPH.

Granted, parades are not a use-case that Nissan needs to optimize for, I was just surprised. If slow driving 30-38MPH is good, I thought really slow driving would be great. Electric motors do not have the limited RPM range of ICE but they do have bands for optimal efficiency."

Suponho que tenha que ver com o atrito maior dos pneus no arranque do carro que tb se deve reglectir a velocidades muito baixas, mas se fosse com mais pressao nos pneus, ou ate com pneus de plastico rigido devia dar valores muito diferentes...
