One of the most difficult aspects of designing an electric or hybrid car is packaging the batteries. A plastic fuel tank can be blow-moulded into amazing shapes and squeezed into the space under the rear seat.
Batteries, however, are big and square and demand lots of space.
At the Detroit show, I noticed that back-up battery for VW’s hybrid concept coupe swallowed up a considerable chunk of the otherwise giant boot.
The Mini E, of course, loses its rear seats in an attempt to squeeze in enough battery power to propel the car a claimed 120 miles.
However, Detroit was also host to an intriguing cut-away display of the Nissan Leaf electric car, which shows the importance of a bespoke engineering if you are trying to build a viable battery-only passenger car.
