Price starts at € 20'000 for the ZE compared to € 11'500 for the ICE (70dCi). Add to that the € 72 per month lease of the battery and the Kangoo ZE is not really a bargain.
I haven't made a calculation to see how incentives and tax breaks change the picture, but it seems you have to be very "green" to buy this EV.
The price of the Fluence seems to be relatively low compared to the Kangoo ZE with € 22'000. It's diesel counterpart (dCi90) costs € 15'350 (ex all taxes)
