Stradale.
The iconic Lancia Delta Integrale, revisited.
The Lancia Delta HF Integrale was built to serve as a base for Lancia’s monstrous Group A rally car. The Maturo Stradale specification is developed taking this iconic WRC Group A champion as its base. Adding countless technical developments, using advanced materials and revising many of the Italian 90’s automotive imperfections.
Chassis
The original chassis is completely stripped, repaired, coated in a special epoxy primer and repainted inside and out. The structural rigidity of the chassis has increased remarkably due to the addition of a custom made roll cage and by welding through over 250+ spots at various weak points.
Carbon Body
Perhaps one of the most disguised advancements of the Stradale specification is its full carbon fiber body. Lightweight, precise and incredibly strong. The fit and finish of the body panels is night and day compared to the original steel plated body, with its common variation in body panel gaps. It also puts an end to the corrosion problems of its original sheet metal body.
Engine
The engine is completely rebuilt to Group A specifications with additional technical advancements, surpassing the original Group A rally car’s performance and durability. The Stradale spec puts out 400hp and 540 Nm.
Various parts of the engine are replaced by lighter, stronger and more precise components. Additionally, a redesigned ECU made in house, enables the engine to deliver its full potential.
Key specs
* Fully rebuilt, Group A spec engine with drastically improved durability and reliability
* Revised Intake: Carbon airbox, enlarged intercooler and rebuilt original Garret Turbo
* Modern injection, motorsport ECU and new wiring harness
Gearbox
Strengthened 5-speed manual gearbox, revised and upgraded known weak gears. Reinforced gearbox housing and internals. Specifically developed to cope with the increase in engine power and to improve shifting performance. Rebuild done in house.
Differentials
The drivetrain of the Maturo Stradale spec is exactly like the Group A rally car. It features both front and rear plated limited slip differentials for ultimate cornering ability. The differential shafts and the drive shafts are replaced with Formula 1 derived special steel ones, capable of twisting at an angle of 40° without deforming. The result is a drivetrain that distributes the engine power more effectively whilst reducing the possibility of technical failures.
Braking System
The brakes are directly carried over from the Maturo Rally Group A Abarth spec. The callipers are made from incredibly strong 7075 billet aluminium. Pedal box operated, truly made for competitive driving. When desired, adjustments to the brake pressure can be made by the driver with a rotary knob mounted on the redesigned handbrake.
Suspension
The Maturo Stradale spec has a far superior suspension system than the original street car. The Maturo Stradale spec is equipped with state-of-the art, 4-way adjustable motorsport shock absorbers. This package is directly derived from Maturo’s Rally specced cars, which have successfully completed numerous competitive rallies.
Interior
Familiar, sophisticated yet renewed. The interior is completely bespoke, built by hand and made out of wonderful materials that meet our present day desires. Inspired by the Group A Abarth rally car and the original street version with a touch of Lancia Delta S4 Stradale. A unique blend of iconic Italian automobiles.
