"EcoJet's genesis goes back to a discussion between Leno, an avid car enthusiast and collector, and Bernard Juchli, the chief mechanic and caretaker of Leno's collection. Leno then turned to Welburn for design direction.
"A couple of paper napkins later, Ed had begun to capture the essence of the car," said Leno. "I've admired the work of GM's Design Studio in North Hollywood, Calif., and asked Ed if the studio's director, Frank Saucedo, and his guys could continue the design study,"
Welburn agreed, and a two-week sketching frenzy commenced as GM's designers began working after-hours with Leno's team on the project"
