Triumph GT6 planned aeromods

[The Toecutter]

I have an EV conversion in progress, and in order to maximize its range, I will be making extensive use of aerodynamic modifications.

My goal, which is to achieve 100 miles range on lead acid batteries at 60 mph to 100% DoD, will not be possible unless I get Cd at or below 0.25.

I have made two drawings, both drawn to scale, one of the GT6 stock, and another with the proposed aerodynamic modifications. On the aeromodded version, I included a dorsal ridge for stability; I'm intent on exceeding 130 mph in this car and I'm not keen on the idea of a stray gust knocking me off course.

Does the Kamm-back appear to be the correct angle? Any concerns? I want to make sure I get this right before I start drilling holes into the body to mount this(I will have cardboard mockups tuft tested once the car is registered and road legal, before making the fiberglass pieces).

The smoothed up, sealed up front end looks good. Most modern cars I've seen have the spats in front of the front tires slightly more toward the center of the vehicle. I like the rear wheel skirts but I am not too sure about the angle of the Kammback. I don't have the aerodynamic template right in front of me but it looks like it should be steeper and should taper in on the sides too.

Looks good :



I got mixed up for a while because I didn't realize that you lowered the green version. That changes the scale of the overlay, so the lines don't line up as well.

Thanks! I'm saving that bottom image as a template for proposals on other vehicles as well, if you don't mind.

I can't wait to see how this body turns out when I finally build it. Given that my job situation has gone bad this year and I need an income source once again before I can spend large sums of money, my Triumph is going to be on the road initially as a 72V conversion; with the right amount of drag reduction and an added 5th gear, 80+ mph is not out of the question, when the norm for a 72V conversion is around 50-60 mph top speed(some 72V examples have exceeded 70 mph, but are not the norm).

The first aeromods that I'm going to permanently install are going to go on my Benz, but I have no way to conveniently measure distance any longer due to a gear set in my odometer having broken. I can, however, plan some long trips beforehand and map the route on google, from one fuel station to another, and fill it up at the very first station, as I have done in the past to get data.

My main concern is figuring out how to attach them with minimal intrusiveness into my car's body. I'm probably going to have to drill holes on the Benz too; I don't mind much, considering I got the car for $1,200, someone was allegedly murdered in it before I bought it, and it's seen its share of hookers courtesy of the previous owner! I'm not intent on restoring it to mint condition...
