Panoz Auto Development was founded in 1989. After a few years of building their first car, the Roadster, the company developed the Esperante so they could compete in sports car racing in 1997. Later, the company would be renamed Panoz LLC.
Panoz produces cars tailered to the buyer's preferences, and can fit almost any engine into their builds.
The Esperante was developed in the late 90s and was revealed in 2000. Panoz's engines are typically sourced from General Motors' LS-based small-block engine and Ford Motor Company's Modular V8 family.
