oui je me posais la même question. mise à part deux cylindres en + , cette ambu me parait pas mal . une deuxieme question me vient . quelle est la diff entre une ambu r2087 et une r2088 ? car vu les photos , je ne vois rien de différent avec la mienne ( à part les feux)

...A ma connaissance, le 2088 n'existe pas chez Renault ...

During its life, the vehicle was fitted with three different engines. The original R2060-R2064 models used the antique Renault type 603 ‘85’ four-cylinder side-valve petrol
engine producing 46bhp from a capacity of 2383cc. In 1952 this unit was replaced by the 668 overhead-
valve motor, turning out 49bhp
from 1996cc and this was fitted to the R2065-R2069, although the Belgian Army R2067 used a more-powerful version of this unit, the so-called 668.5, producing 50bhp. From 1956, the R2086-R2088 models were fitted with the type 671 engine, this time producing 64bhp from 2141cc. All versions used a four-speed gearbox (either the Renault 259, 269 or 280 unit) and the all-wheel drive variants were fitted with a Renault 274 two-speed transfer box using a single control lever to select both the four-wheel drive and the low ratios.
