Not sure about 40mpg

But I would think 30mpg at city speeds might be possible.

For Higher speeds he would need to start constructing a long belly pan and likely be careful with tire /rim selection and start streamlining gaps and protuberances
Alignment and stance of the chassis will likely need touching as well, he would need to set things a little on the squirmy side to get best efficiency.

Step 1 is to drive the chassis with instrumentation a lot to figure out where he is starting.

A CD .75 brick is likely lower on the spectrum than some might figure but also easier to streamline.
