The Birth of a Legend
Lancia knew they needed something extraordinary to compete in the fierce Group B category of the World Rally Championship. The result was the Delta S4, a car that shared little more than its name with the production Delta model. Lancia designed this purpose-built machine from the ground up to dominate the stages.
The Lancia S4 chassis featured a unique drivetrain that set it apart from competitors like the Audi Quattro. While Audi relied on all-wheel drive and turbocharging, Lancia took things a step further. The S4 engine employed boost from both a supercharger and a turbocharger, a system designed to eliminate turbo lag and provide instant power delivery across the entire rev range.
This innovative “twincharger” setup allowed the S4 to accelerate from 0-60 mph in a mere 2.5 seconds on gravel – a feat that remains impressive even by today’s standards. The engine, a 1.8-liter four-cylinder, could produce over 500 horsepower in race trim, with some sources claiming outputs approaching 1,000 hp when boost pressure was turned up to the maximum.
Engineering Marvels
The Delta S4’s chassis was a tubular space frame design, providing both strength and lightness with minimum weight. Lancia’s engineers paid careful attention to the car’s suspension, employing double wishbones with twin shock absorbers at each wheel. This setup allowed for precise handling on various surfaces, from tarmac to gravel and snow. On the chassis, the transmission was a five-speed gearbox with a center differential, allowing power to be distributed effectively to all four wheels.
Aerodynamics played a crucial role in the S4’s design. The distinctive rear wing and numerous air intakes helped manage flow of air and cooling, essential for a car pushing the limits.
The Stradale Version
To meet homologation requirements, Lancia produced a limited number of road-going versions called the Lancia Delta S4 Stradale. While its smaller engine tamed compared to its counterpart, the Stradale was still a formidable machine. The interior of the Stradale version featured more creature comforts than the Spartan rally car, including leather seats and power windows.
Group B: The Golden Era of Rally
The Lancia S4 made its competitive debut in the 1985 RAC Rally, securing a victory in its first outing. This impressive start set the stage for what promised to be a dominant run in the championship.
Triumph and Tragedy
The 1986 season started strongly for Lancia, when Henri Toivonen and co-driver Sergio Cresto won at the Monte Carlo Rally.
However, the Group B period was as dangerous as it was exciting. The extreme performance of these cars, combined with the often treacherous stages, created a recipe for disaster. Tragically, this came to a head during the 1986 Tour de Corse.
On May 2, 1986, Henri Toivonen and Sergio Cresto were involved in a fatal accident during the race. Their S4 left the course and caught fire, killing both the driver and co-driver. This tragic event, combined with other accidents during the season, led to the cancellation of Group B at the end of 1986.
Legacy and Impact
After the demise of Group B races, Lancia continued its rallying success with the Delta HF, which dominated the Group A period. This car, while less extreme than the S4, carried forward the legacy of Lancia’s rallying prowess.
Collecting and Preserving the Legend
Today, the Lancia S4 is a highly sought-after collector’s item. With only a few dozen Lancia Delta S4 Stradale versions produced, these road-going Group B homologation specials command high prices when they come up for sale.
Each Delta S4 Stradale has a unique chassis number, making them easily identifiable. The rarity and historical significance of these vehicles means that their value continues to appreciate as they’re sold.
The Lancia Delta S4 in Popular Culture
The drama of the S4 and the Group B period has captured the imagination of motorsport fans for decades. It has been featured in numerous documentaries, books, and video games, cementing its place in automotive lore.
The car’s distinctive sound – a combination of supercharger whine and turbo whistle – is instantly recognizable to fans. The auditory signature of the supercharger and engine, coupled with the visual impact of the chassis, makes the S4 an unforgettable icon of 1980s motorsport.
Protecting Your Piece of Rally History
Owning a piece of automotive history like the Lancia Delta S4 or its road-going version, the Delta S4 Stradale, comes with great responsibility. These cars, much like those from Abarth and Peugeot, are more than just developed vehicles – they’re rolling museums of engineering prowess.
From the innovative twincharged engine system combining a supercharger and turbocharger, to the sophisticated all-wheel-drive transmission, every component of the S4 tells a tale of automotive evolution. The lightweight chassis and even seemingly mundane parts like the windows, rear wing, and windscreen were all carefully designed to balance weight, speed, torque, and performance.
Given the rarity and historical significance of these cars, it’s crucial to protect your investment with specialized classic car insurance. Standard auto policies often fall short when it comes to covering the unique needs of vintage vehicles.
