Rally racing is a legendary discipline that has marked the history of motor sport with its exploits, legendary cars and daring drivers. Among the most fascinating eras of this discipline, Group B remains unquestionably the most emblematic. Active between 1982 and 1986, this category saw the birth of monsters of power and engineering, and left an indelible imprint on the imagination of fans.
In this blog, we look at the heart of Group B through the eyes of three iconic models: the first Lancia Delta, the Audi Quattro and the French Peugeot 205 T16, not forgetting the figures who contributed to their legend.
The Lancia Delta S4: The Italian Revolution
The Lancia Delta S4 represents a major evolution in the history of rallying. Designed to dominate Group B, it combined technological innovation with impressive performance. Under its bonnet, a twin-supercharged engine (turbo and compressor) produced more than 500 bhp, a feat for its time.
The car was equipped with all-wheel drive, offering exceptional grip on all types of terrain. The perfect balance between raw power and handling made the Delta S4 a formidable weapon on the track.
Highlights:
In 1985, the Lancia Delta S4 made its debut on the RAC Rally, winning on its first appearance.
It was also involved in some tragic moments, including the fatal crash of Henri Toivonen and co-driver Sergio Cresto in the 1986 Tour of Corsica, which marked the end of Group B.
Why it’s legendary:
The Delta S4 embodies the essence of Group B: bold technology, unparalleled performance and an intensity that bordered on the limits of what was possible.
Audi Quattro: The Four-Wheel Drive Revolution
Audi Quattro is another Group B icon, renowned for revolutionising rallying with its permanent all-wheel drive. Introduced in 1980, well before the official creation of Group B, it set a new standard for traction on varied terrain.
Power engine:
With a turbocharged five-cylinder engine that developed up to 450bhp in its competition versions, the Audi Quattro was a true racing beast. Its ability to maintain optimum grip even in extreme conditions made it a formidable competitor.
Michèle Mouton: a daring pioneer
The Audi Quattro is also associated with Michèle Mouton, the first woman to win a round of the World Rally Championship (WRC). In 1981, at the wheel of the Audi Quattro, she made history by winning the Sanremo Rally. Her talent and determination shattered stereotypes in a sport dominated by men.
Why it’s legendary :
The Audi Quattro redefined the technical standards of rallying and ushered in a new era for all-wheel drive. It remains a symbol of avant-garde technology and bravery behind the wheel.
The Peugeot 205 Turbo 16: The French response
The Peugeot 205 Turbo 16, often abbreviated to 205 T16, was the French contribution to the Group B legend. Designed specifically for competition, it shared little with the mass-market version, apart from its name and body shape.
Unique architecture:
With a 1.8-litre turbocharged engine in a mid-rear position and all-wheel drive, the 205 T16 was a machine built for performance. It was capable of producing more than 400 bhp in its competition version.
Achievements:
The 205 T16 dominated the World Rally Championship, winning back-to-back titles in 1985 and 1986. It was driven by legends such as Ari Vatanen and Timo Salonen, who exploited its potential to the full.
Why it’s legendary :
The Peugeot 205 T16 represents French ingenuity and competitiveness. Its impressive track record and bold design make it a true Group B icon.
Group B: An Era to Remember
Group B has left an indelible mark on the history of rallying. Although the category was discontinued because of the risks it represented for drivers and spectators, it remains a symbol of innovation and unbridled passion. The Lancia Delta S4, Audi Quattro and Peugeot 205 T16 are perfect representatives of this legendary era, each making their own unique contribution to the heritage of motor sport.
These cars, combined with the courage and talent of the drivers who tamed them, will continue to inspire generations of enthusiasts. Group B is more than just a rally category: it’s an epic story that we’ll always enjoy telling.
Those cars are absolute beasts, forged in fire and raw power, made to dominate tracks and especially mountain passes. Hopefully, we’ll get the chance to try one in the coming years!
