So this is what i came up with

Do you have any means of assessing the result? For example A-B coast-down testing?

just got back from my trip to wembley which is a 60km round trip
usually it takes all of my charge to do that journey, but after all of the mods iv added to the car thanks to your kind suggestions and tips on this site, i returned home tonight with a quarter of my charge left.
that is hugely significant, from 60km to 75km
now i want to make it better and more rounded
i also want to raise the bonnet to make it scoop the air over the car better
and im yet to put those wheel skirts on too

thanks guys, ill keep you posted

Just hope that it doesn't rain.

What you have so far is ineffectual from the taillights on down. Do you have a plan that ties together the bottom of the hatch, a diverter and the trailing edge of the skirts?

delete the mud flaps
air deflectors ahead of the wheels

Very nice test results. As much as I like modding the fuel burners, improving your car changes the whole utility of it. Adding range without adding weight, batteries, complexity is priceless.

There was a poster here that moved the mudflaps from behind to in front of the tire by swapping them side to side, and saw a nice improvement in mpg. I haven't been able to find the thread. Anyone else? I seem to recall it was on a Mazda.

it is a legal requirement to have mud flaps

cops in perth are the fun police, i have to be super careful with anything i do because they might yellow sticker me just for fun, iv had to really tidy up the side skirts and chin spoiler so nothing sticks out too much and it all has rounded edges

i had the cardboard kamm back thing on the back for 2 trips to wembley and both times there was noticeable improvement

so i took it off tonight to see how much the kamm back on its own was improving the range
im gonna make a proper thing for it because its starting to come apart already
thankyou guys
