An ICEV chassis does not make a very good EV. The ICEVs that have been converted to EV, like the Ford Focus EV, don’t have enough room for a larger battery and have usually only had a battery with around 70-100 mile range. The battery usually intrudes into the cargo area reducing the space for luggage and groceries.

Another problem is that the EV conversion adds a lot to the price. Then at the dealership, customers see an expensive Focus EV sitting next to a less expensive ICEV Focus and they tend to choose the less expensive option.
