The Gray Ghost is a driver for the "Écran Etablissement" team, an independent French sponsored team, who appears in the movie but not in the original anime. The car itself is a T-180 series vehicle whose number is 23 (the three is substituted by an E representing the words Écran and Établissement). The car's titanium alloy body is painted with a black background with gray and blue colored smoke trails.
Upon opening up the package and checking the design, coloring, and special features of this car it quickly became my favorite. Yes, the Mach 5 is awesome, but there's something about this one that really grabs me. First. it's a fairly big car. It comes with a black two-piece shroud that gives it a beefy appearance. One attaches the two shroud halves to the secondary body, pulls the car back and releases it. After a short distance, the two halves automatically separate from the secondary body underneath to reveal a really cool transparent gray T-180 car!! Now that's a special feature Enjoy!
