The most exciting cars ever to grace the rally scene, and still considered the epitome of madness on wheels by many.

This is the story of all the Group B cars, the Quattros, the outstanding Lancias and Peugeots, the exotic Porsche and Mazda and more.

John Davenport, rally-journalist and Austin Rover motorsport director at the time, reveals the fascinating world of these hi-tech machines, offering an authoritative insight into the power struggles behind the scenes.

Packed with photos from well-known rally photographer Reinhard Klein.

'Okay, so it's been a while since rallying was really exciting, but you'd be forgiven for failing to notice after even a quick skim through this book. Stunning photography, as ever, from the renowned McKlein studios and insightful analysis from John Davenport goes together perfectly as every car from the Group B era - even the disastrous Citroen BX 4TC - and all the main drivers are featured.
