Converted by the Jaguar Works as a concept

The drive train (batteries, motors, etc) same space, but slightly lower weight than the original, so better performance, but same handling as the original.
Jaguar says they might make it a commercial car, depending on demand.
They could not have had a better launch platform :)
Brilliant marketing/product placement to show off classic British design combined with cutting-edge technology.
