The BX 4TC Evo was Citroën's weapon for the B-group World Rally Championship. The 4TC Evolution was classified with a 4TC (a series of 200 cars). The car was officially launched by Citroen in November 1985 ment for he World Rally Championship season 1986.
The 4TC was far from similar to normal BX's, and the 4TC Evolution was far from similar to the 4TC street version. The last Evo version had a number of radiators in the back and a different turbo (KKK). The first Evolution version had 6 round headlights and this version was only tested before the final version was created. Both types (evo and street version) had the hydropneumatic suspension. Transmission was borrowed from the SM and brakes from the CX.
The nose of the 4TC was a lot longer then the normal BX because a 4 cylinder 2 litre engine had to be rotated by 90 degrees compared with the normal BX-engine.
The 4TC was a fast and very luxurious car. The interior (for 5 passengers) was similar to the yet to be launched BX Sport, including the steering wheel. On the dashboard a few additional gauges (for example engine temperature indicator) were added.
Bonnet, tailgate and all the wings are plastic in both versions. 4TC's have six head lights and 210/55 VR 390 tyres on 150 TR 380 FH alloy wheels. The last Evo versions had only 2 small headlights to permit as much cooling area as possible in front of the car.

Two BX-4TC-200 series cars were displayed at the ICCCR - 98 meeting held in Belgium.
Both cars were in very good shape (as new) and completely original. BX-SPORT owner Robbert Bakker toke some very nice pictures of these cars which can be found below.
On these pictures it is clear that the car has a very huge nose and the front and rearbumpers have much in common with those used on the BX SPORT.
One of the cars was noticed by Robbert Bakker during arrival and Robbert mentioned that its sound was incredible.
