According to Pi ch, one supplier says the components can be had for around $6,775, not $47,400 as had been calculated. Of course, the 1-Liter concept was powered by an 8.5-horsepower, 299 cc one-cylinder engine, while anything built for the marketplace would likely have to come in a bit higher on all those specs to be viable.
