CitroŽn BX

The BX was launched in 1982 after only 5 years of development work and went on to become one of the company's greatest successes. Initially available with a choice of 1 360cm3/63 bhp, 1 360cm3/72 bhp or 1 580cm3/90 bhp petrol engines, the range was soon expanded to include diesels, 4 x 4s and a number of much more powerful variants.


The first performance version of the BX was launched in 1984. It was equipped with a 1 905 cm3 carburettor engine developing 105 bhp, close ratio gearbox, stiffer suspension than the other models in the range, circular instruments, additional lights and a rear spoiler. The GT had a top speed of 185 kph/115 mph.


Then, in 1985, came the BX 4 TC - a four wheel drive homologation special intended for Group B competition. It was equipped with a turbo charged longitudinally mounted four cylinder engine of 2 141cm3 capacity developing 200 bhp. Twenty Evolution versions participated in the 1986 World Rally Championship events.

Carrozzeria Bertone used the BX 4 TC as the basis of their Zabrus .
