In 1967 BMC added the Wolseley 18/85 to its well designed, 1800 "Landcrab" range. Unusually for BMC the new cars were only built in Austin/Morris and Wolseley trim, they managed to resist offering identical Riley and MG variants. The 18/85 used the same 1800 B-series engine as the rest of the range, however a 96bhp, twin carb "S" version joined the line-up in 1969 along with the MkII version of the standard car.
The MkI 18/85 had its own unique rear lamps to help distinguish it from the Austin/Morris cars along with the traditional Wolseley grille. Options available on the 18/85 included reclining front seats and automatic transmission, complete with dashboard mounted gear change. The 18/85 remained in production until 1972 when it was replaced by the larger engined 2200 model.
