Hugely underwhelming to look at. See also the Mondeo comments above.
However….I think that may be a good thing. For too long, “eco”* cars have looked silly. Silly as in, “Ooooh, look at me, everyone, I’m saving the little fluffy polar bears! I must be a great person. Did I mention I was saving the planet with my lovely, cuddly car? I mean, just look at it! No one would drive something this silly looking if it wasn’t saving ickle baby seals”.
Tesla, at least with this one, seem to have taken a positive step to make it look like a car. Just a very ordinary car. Less about showing off, more about just being a car.
* Eco credentials can be questioned for most. Especially as most are promoted for urban use. Exactly where a car shouldn’t be used.
