Essentially the car is controlled by a dash-mounted dial which allows it to operate in two different modes.
Set the dial to ‘Commuting’ mode and the power is dialled back to just 44kW, even less than is under the bonnet of a regular Fiat 500, and returns 4.0-litres per 100km. Flick it over to 'Highway' mode and the E2 develops an impressive 120kW.
Surprisingly even in 'Highway' mode the E2 still manages 6.4L/100km.
Rinspeed said the car demonstrates how the tuning house is flexible in changing itself to meet new world consumer demand.
Unfortunately the car will not make it beyond concept stage, and it's hard to say whether the vehicle presents any real production value, but it certainly proves what can be achieved with some intuitive lateral thinking.
