 === Transmission and Rear Differential === === Transmission and Rear Differential ===
-All four Iltises retained their standard transmission gearing and rear differential. However, for Iltis No. 138, which produced more than 150 hp, the engineers decided to lock the transmission in four-wheel drive, believing that the increased power would make the vehicle difficult to control when driven on a single axle. Jean Ragnotti, who had extensive experience in rear-wheel-drive rally cars, later expressed regret over this decision, as it limited his ability to use the throttle to help rotate the car through corners.+All four Iltises retained their standard transmission gearing and rear differential.

 The exhaust pipe was shortened to exit on the passenger side, just ahead of the rear wheel. A full-length exhaust system was unnecessary, while the shorter pipe reduced the risk of snagging on obstacles during the rally. The exhaust pipe was shortened to exit on the passenger side, just ahead of the rear wheel.

 +The braking system remained in factory specification, with //no// reported modifications to the brakes to compensate for the increased engine output. Reportedly, this was particularly significant for Iltis No. 138 with nearly twice the horsepower of a stock Iltis.

-<del>The seat fabric appears to be from a late 1970s Audi. The foundation of the seat may be Audi as well, but is unknown.</del>+The exact origin of the seats remains unknown. The tan-coloured upholstery fabric and pattern are consistent with those used in late-1970s Audi models, while the seatbacks resemble those fitted to civilian Iltises, featuring integrated headrests and black plastic rear panels. However, the large side bolsters on the seat cushions differ from both of these designs, making a definitive identification difficult.

-<del>Converted from 24 volt to 12 volt???</del>+As 1979 Bundeswehr-specification vehicles, the Iltises would originally have been equipped with 24-volt electrical systems. However, some of the additional rally equipment, including radios, auxiliary gauges, and rally lights, may have required 12-volt power. How this difference was accommodated remains uncertain. One possibility is that a voltage converter or separate 12-volt supply circuit was installed to power the additional equipment. Alternatively, the original 24-volt electrical system may have been replaced or extensively adapted to use the 12-volt system found in civilian Iltis models.
