They're identical when you drive the Jaguar at low speeds in town, using mainly electric power and plugging in as soon as you get home, and the Prius like a normal car. Which is a bit misleading.
Porsche does the same thing with the 918. "And Porsche says it will do 94mpg," Richard Hammond proclaimed on Top Gear. Well...not if you drive it like he did.
That said, I imagine most of these cars will end up as garage queens, driven to the odd car show or nice restaurant. So, maybe their real-world MPG will be closer to these advertising numbers?
