Out on the high-speed corners of the gloriously unspoilt (ie scary) Goodwood circuit, the Leaf is a strange experience. There are no gears to juggle, no clutch to operate, no engine noise to help you make sense of negotiating the circuit. It’s incredible just how much we rely on aural signals when driving a car quickly. With just a high-pitched whine as accompaniment you feel completely removed from the process, making it very tricky to judge your entry speed to corners and even the grip available through them. When the first diesel-powered Audis conquered Le Mans the drivers all said how difficult it was to extract the maximum out of the cars with so little engine noise for reference. Here the effect is exaggerated further. There is noise, but it bears no relation to the images streaming into your brain.
