1986 Citroen BX 4TC

Citroen produced a large family car called the BX from 1982 to 1994, with over 2.3 million examples built.

The Citroën BX 4TC was built to contest Group B rallying. Sixty-two examples were eventually built. Power was from a 2,141cc dual overhead cam four-cylinder engine fitted with a single Garrett T3 turbocharger and a Bosch Multi-Point electronic fuel injection system. The 200-horsepower engine was backed by a five-speed manual gearbox. They had a four-wheel-drive system and ventilated disc brakes at all four corners. The suspension was an independent Hydropneumatic double-wishbone setup.

The styling of the BX 4TC differed completely from the standard BX. In the front was a very long nose due to the engine which was mounted longitudinally, unlike the regular BX setup.

The 4TC competed in just three rallies before the Group B class was banned in late 1986 following the tragic death of Henri Toivonen in his Lancia Delta S4 at the Tour de Corse Rally. The most successful finish in the World Rally Championship competition by the 4TC was sixth place in the 1986 Swedish Rally.
