When gathering the full Group B field, a collection often slams shut after that initial group of six, leaving the truly rare models out in the cold. But fortunately for GRR, this year's Retromobile did not neglect those other manufacturers who gamely made up the rest of the field in rallying's most extreme age but were so cruelly removed from its major history.
First up is Citroën – this is a French show after all – the other half of the PSA group had not one, but two cars to its name. OK so the Visa wasn't initially a Group B car, but it did compete in the era, initially in front-wheel-drive form before eventually becoming the 4x4 1000 Pistes edition we see before us. This Group B version still only toted around 112bhp (compared to the 600bhp monsters around it) but as 200 were made and it could be easily homologated to other regulations it was a car that transcended its age, going on to achieve relative success when the big bangers were banned.
Citroën really dove head first into the Group B mire, with the BX 4TC – a car which looks like the sad lovechild of the Audi Quattro and the Lancia Delta S4. The front-engined, monocoque-chassised 4TC didn't arrive until 1986, by which time the majority of its competitors had already switched to lightweight spaceframes and shoehorning engines of much too many litres into the back rather than the bonnet. Thus, the Citroën faced an uphill struggle straight away. Sadly for the quirky BX, it would compete in three WRC events, suffer three mechanical failures and return to its crate never to be seen again. Citroën had built so few 4TCs that after they recalled them for destruction not many remained, therefore this could perhaps regard itself as even more historically valuable than the others (sort of).
