Vespa pretty much pulled out all the stops when it came to the 946, putting style and the display of technology at the front of the bus. The monocoque chassis – a hallmark of the Vespa – is labor-intensive to build, with 320 welds. The curves and shapes evoke the original D'Ascancio-designed 1946 MP6 prototype (hence the '946' designation), if not the original's size and simplicity. There are some aluminum panels bolted on, but the scooter's main structure is made of sheets of steel, just like the first prototypes.
