"What siai47 says makes sense, but I experience that the power gauge jump is not followed by a speed change. My speed remains constant, only the power gauge changes. While power consumption is low and speed is high, as would be on a flat road, B seems to require less power than (european) D." tomrh, Oct 17.
"I confirm what tomrh says, the power gauge jump in not followed by a speed change. When we change to B, we don´t feel any kind of breaking, and the instrumentation confirm that. And the car just keep on going at the same speed." Malm, Oct 17.
