The final version of Lancia’s infamous World Rally Champion trophy winner: The Lancia Delta HF Integrale 16V Evoluzione. Lancia’s WRC Group A journey started in 1987 and ended in late 1991 with their Abarth works team, claiming a staggering 46 rally victories. In 1992, Martini Racing partnered with Jolly Club, to further develop the Lancia Delta, stretching its dominating rally presence beyond the Lancia works period.
Making Lancia the most successful team in the history of the world rally championship.

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 FIA approved roll cage and by welding through over 250+ spots. Resulting in better structural performance than the original Group A rally car.
A completely rebuilt engine with Group A specifications and additional technical advancements, surpassing the original Group A rally car’s performance and durability. Various parts of the engine are replaced by lighter, stronger and more precise components. The end result is a fully Homologated FIA HTP approved engine with better specs than the original Group A rally car.
The original Group A gearbox was developed just before the full sequential shifting technique was available. Back in 1991 the WRC cars had a dog-Leg gearbox with straight-toothed gear wheels. Providing blistering fast gear shifts, without the need to use the clutch under hard acceleration or braking. However, it’s not for the faint hearted.
The drivetrain of the Maturo Rally spec is completely different from that of the original street car. Both the front and rear differentials are upgraded to plated limited slip diffs for ultimate cornering ability. The differential shafts and the drive shafts are replaced with Formula 1 derived special steel shafts, 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.
As with the original Group A rally car, the brakes are controlled by a non-assisted pedal box system, made for true competitive rallying. Fully FIA HTP homologated and ready for duty. Additionally, when the situation [read: rally stage] calls for it: adjustments on the front and rear brake bias and brake pressure can be made by the driver with two rotary knobs, located in the cockpit.
Although using the same technology, the Maturo Rally spec holds a much more developed suspension package than the original Group A rally car. Together with Intrax, the ultimate, data proven rally set-up has been determined. This accommodates for a much better and more refined ride, whilst boosting the cars’ controllability and thus, its potential maneuvering speed.
The interior of the Maturo Rally spec is exactly according to the 1991 Group A rally specification with Abarth hints and details, like original. Sitting down in the bucket seat and putting your feet on the kevlar finished floor panels is like stepping into a time machine, taking you back to the iconic days of Group A rallying.
