I know my Volt is electronically limited @ 160km/h. It doesn't bother me, so 180km/h shouldn't be either.
But my former Spark EV was electronically limited @ 144km/h: that was bothering me while overtaking someone on a 2 way road, the electric motor still pulled strong then an unexpected "silent bang", it hit a glass roof ceiling. Frustrating it was, would have say Yoda.
