Citroën BX 4TC

Citroën BX 4TC was the pinacle of Citroën's group B efforts. It was based on a similar concept to the Audi Quattro, in that it had a front-engine, monocoque chassis design. The BX 4TC could have been successful had it been introduced earlier, but because it was introduced in 1986, it was outclassed by competitors with space frames, mid-engine layouts and a several year development advantage. The BX 4TC competed in one world championship rally, suffered three mechanical failures, was rolled back onto the boat, and was never seen again in world rally competition.

Citroën built 20 of these Evolution BX 4TC's in the Citroën Competition workshop at Trappes. Technical father Guy Verrier developed this car using only Citroen parts, elements and mechanics.

The engine reved to a maximum of 8000 rpm, maximum power of 380 bhp and 7000 rpm and maximum torque 253ft/lbs. at 5500 rpm. Drivers Jean-Claude Andruet and Phillipe Wambergue performed development tests piloted the BX 4TC's in rallies.
