Compromised Internals

Overview Specs Highlights Characteristics

Overview

The Citroën BX 4TC was developed in haste as Citroën’s official Group B entry. Launched in 1986, it was based on the standard BX road car and built to satisfy homologation requirements, but its heavy front-engine layout and lack of proper rally development made it one of the least competitive Group B machines. Though it carried over Citroën’s hydropneumatic suspension system and featured all-wheel drive, the BX 4TC struggled on almost every surface. It competed in only a handful of WRC events before Group B was canceled and Citroën withdrew the program entirely.

Technical Specs & Innovations

Despite its unusual technology, the BX 4TC was compromised from the start — too heavy, too long, and underdeveloped. Its layout was outdated compared to mid-engine rivals, and reliability issues plagued early entries.

🏆 Competitive Highlights

1986 Monte Carlo Rally: Debut entry ends in early retirement.
1986 Swedish Rally: Best result — 6th place overall by Jean-Claude Andruet.
WRC Participation: Only three entries before Citroën canceled the program.

The BX 4TC never had time to evolve. It was introduced just as Group B was collapsing under scrutiny, and Citroën quickly distanced itself from the failed campaign — even buying back and destroying many of the road-going homologation cars.

Driving Characteristics

The BX 4TC was awkward and difficult to handle. Its long front overhang created understeer, while the car’s soft suspension setup — though innovative — didn’t suit fast or bumpy stages. Drivers had to wrestle with turbo lag and chassis imbalance, making it hard to compete with more refined rivals. It was a handful, even for seasoned professionals.
