There are only a few plug-in electric cars available in Turkey.
If memory serves us right, the BMW i3, BMW i8, Nissan LEAF and Renault ZOE are the only plug-in electric cars sold in Turkey.
Out of that list, the Renault ZOE was chosen as the "Most Environmental Car" by Top Gear Turkey.
Why not the i3? Our guess is that its availability in Turkey is extremely limited and perhaps one wasn't even available for Top Gear to test. ZOE, on the other hand, is now rather widely available in Turkey and Renault has a strong presence in that nation too. Again, this is all just a guess.
