Here's a very informative animated video of the VW XL1:
In particular, the frontal area is 1.50 sq m which is 16.146 sq ft. The Cd is 0.189, so the CdA is just
3.05 sq ft. The EV1 is 3.96 sq ft.
Notice the location of the battery pack - it is tucked into the space just ahead of the passenger, which is staggered back from the driver.
