Organisers let increasingly attractive electric cars speak for themselves.
Electric cars no longer look like home appliances, and as a result have started to generate genuine interest from a curious buying public.

Visitors to the show will be able to take a variety of electric machines for a spin on a 5km circuit.
Show organiser Giles Brown was taking the proof-in-the-pudding approach.
