Because there's no engine noise you tend to notice things like suspension, wind and tyre noise. So, Nissan's boffins spent a great deal of time working on suppressing said noise. And they've done an amazing job. The LEAF features soundproof glass, dampened windscreen wipers and vibration-proof mounts for the electric motor.
In terms of being a practical around town car, the LEAF ticks almost all of the boxes, and with a range of between 100-170 kilometres its got more than enough to get you to and from work each day.
