History
Citroën started the BX 4TC in 1983 under competition chief Guy Verrier, building on the production BX's steel monocoque and hydropneumatic suspension. A turbocharged 2.2-litre N9TE engine was fitted longitudinally to allow four-wheel drive. The road car was quoted at 200 hp against 380 hp for the Evolution competition car, and homologation came only on 1 January 1986.
RM Sotheby's says only 62 BX 4TCs are understood to have been sold, and The Drive also reports 62 road cars sold. The Serie 200 was built in two series, with chassis numbers beginning "XL00" in the first series and "XL30" in the second.
