This BMW i3 review by Australia's Car Advice suggest that the ground-up built BMW i3 is a little car with lots of character:
"The BMW i3 is an intriguing little car. It's quirky looking and certainly not your usual BMW design, but then it has been built from the ground up to be an entirely new car for the German manufacturer."
We had both models through the CarAdvice garage, the i3 BEV or fully electric model with a 360V battery powering the electric motor and the i3 REX, equipped with an electric motor as well as a small range-extending petrol engine."
"Given that it's not only a new series for BMW, but also it's first foray into electric vehicles, there was a lot to explore. From concept to production line, for BMW the onus was on using sustainable, eco-friendly materials and manufacturing techniques."
