foifoi05, one of Tsikot design group's star designers, has returned! Where have you been? The guy responsible for the wonderful Tinapay and Tableta PHUV concepts. People smile at the whimsical Tableta without realizing that it is a clever combination of flat and curved panels. People react positively to it. They don't go "Ugh! Flat panels!"
Actually the concept C1A borrows a page from the Tableta and the Tinapay. Like the Tableta, the C1A is also made of flat and curved panels. And both the Tinapay and the C1A pays homage to the Renault 16 roof treatment.
The C1A may have a bit more complicated surfaces compared to, say, an Anfra, but I think the C1A is doable on a PHUV budget. For example - the C1A curved A-pillar and roof sides can be moulded plastic (or fiberglass or sawdust mixed with resin) resting on the steel body. The steel body carries the stress. The moulded plastic parts are just cosmetic and hides the flat roof and flat windshield.
