Looking at photos are one thing but seeing a concept car in real life is another. The e:S has some really small rear seats though making it somewhat like a 2+2, but you’re better off using that space as a boot instead.
To give you an idea, the e:S Concept’s 2,175mm wheelbase is actually even shorter than the now-”extinct” Kancil’s 2,280mm wheelbase. It’s based on an existing platform but had its wheelbase shortened so it should mean the development cost for a production car would not be excessively high.
Weight loss techniques such as slim and lightweight seats and light materials give the e:S a total weight of 700 kg. As a result, its 660cc engine with auto-start stop can take it as far as 30km on a liter of fuel under the Japan 10-15 drive mode.
