Replacing the head and top-end gaskets, transmission cooler lines, and radiator on my 1990 Olds took about forty hours. In that same time frame, the Patron Highcraft endurance racing team stuffed their ARX-02a prototype, collected the bits after three full midair revolutions and a hell of a hard landing, assessed the damage, and rebuilt the car from scratch. The actual rebuild took just over 20 hours, and the team took an impressive time-lapse video of the process.
Race vehicles must be designed for straightforward service, and it’s obvious that the Acuras are pretty well-done in that department. Many a production car could benefit from some of the techniques used for race vehicles, and it’s always something designers should have in mind.
