The original Sigma GTE was commissioned by a Brazilian Biodiesel manufacturing company wanting to produce some unique cars for international sales. This body style incorporates design ideas from the client and other design ideas of the past.
Like our Berlinetta and other high speed cars can be built using a number of different donor chassis's to create a different look. This gives each client the ability to use a manufacture's brand donor vehicle that they personally like.
Most every manufacture has copied the styling cues from Ferrari over the years and this holds true with Sigma design directions. This makes it easy to find donor vehicles with a roof line that flows with the Sigma body. These are some electric conversions using the original Sigma GTE molds with a different window and top from the donor vehicle.
