Unveiled at an exclusive event held at Garage 21 in Milan, the Diablo Eccentrica is a restomod based on the 1990s Diablo that pays tribute to one of the most iconic Lamborghini models ever produced. It is the first project by San Marino-based Eccentrica, a start-up that wants to take its restomod (state-of-the-art restorations of classic cars) business globally. And the company is very open about how titanium 3D printing played a key role in ensuring superior lightness, greater rigidity, and a more precise build to the vehicle without sacrificing its original beauty.

Eccentrica was founded by Emanuel Colombini, a  dynamic entrepreneur, who served as the CEO of the family business, the Colombini Group, for 15 years growing the company to 1,200 employees and €300 million in revnues. Colombini has a strong connection with Lamborghini and is a collector of classic cars. He is also a passionate driver who participates in the Super Trofeo Lamborghini as an AM driver. His aim was to innovate the Diablo, a classic supercar from the 90s, while still maintaining its unique identity.

Emanuel Colombini stated, “As a child I remember seeing the red Diablo in the first release of the Quattroruote magazine. It was love at first sight! It’s hard for other cars to leave such a strong impression on me. Later, after having had the chance to drive the GT version, I decided to pay homage to it, conceiving of a restomod company built around this project. At its essence lies the idea that the hypercar and supercar market will require a product with a more authentic soul, precisely like the sensations drivers experienced while driving these speedsters.”

Restomods and 3D printing

Restomods begin with an iconic vehicle that is no longer produced, known as the “donor car”. It is then redesigned and reconstructed with modern components to create a car with advanced technical features and high-quality finishes, while still retaining its unique character from the past. The synergies with 3D printing as a key technology to modify a very limited batch of luxury car parts are self-evident. Many of the companies involved in the project are known AM users (though less open about it).

For the Eccentrica, the donor car used is from the first series of the Diablo model. When the supercar was first introduced in January 1990, it quickly gained popularity due to its sleek and aggressive design by Marcello Gandini, as well as its impressive performance. In fact, it was the fastest production car at the time, with a maximum speed of 325 km/h.

The Diablo Eccentrica, initially, is a singular and exclusive automobile, with 19 distinctive models, that is bound to become increasingly valuable over time due to its rarity and popularity within the innovative yet nostalgic sector. It has already secured a group of distinguished investors, such as Angelo Radici, the President of the Radici Group (a leading producer of nylon materials, including filaments for 3D printing), as well as Riccardo Marzorati, and Giovanni Battista Vacchi, AD of the Colombini Group and Founder of GBV Partners.

The prototype features parts from unique companies in the automotive industry, as well as renowned technical partners. Pirelli provided the tires, Brembo created the braking system, Marantz designed the audio system, Capristo produced the exhaust system, and Alcantara made the upholstery.

The bodywork of the donor car was completely revised except for the windshield, which remains the same. All the other parts (bumpers, hoods, flanks, and side skirts) have been replaced with new components, providing perfect integration and greater efficiency. Everything has been enhanced by a series of eye-catching details which will not go unnoticed to an expert eye or an Italian design lover.

From the past to the future

As anticipated, Eccentrica highlighted how the various elements in titanium created with 3D printing technology are key to ensuring superior lightness, greater rigidity, and a more precise build. Another refined element of workmanship can be found in the vehicle’s grill, which has a three-dimensional form and a new design to guarantee optimal airflow. Thus, that which was only decorative before has now become an integral part of the project, contributing at the same time to the functionality and aesthetics of the car.

In this project, 3D printing technology allowed for the inclusion of elements in a more integrated way, as demonstrated by the Eccentrica logo, which has been directly formed inside the grill, and the lights of the license plate, which emerge from the grill when inserted into the housing.

Once the technical development has been completed, the Diablo Eccentrica will be a street-legal vehicle but also fit for those who want to hit the track. In its first virtual simulations, it performs like a real hyper car with acceleration from 0 to 100 km/h in just 3.5 seconds, a top speed of 335 km/h, and a lateral acceleration in curves of 1.2g.

The original 5.7-liter V12 engine has been altered to provide technical improvements like new valves and camshafts, slightly increasing its maximum power (550 HP at 7,000 rpm) and maximum torque (600 Nm at 6,5000 rpm). This intervention, which is still in the validation phase, has been combined with wide use of composite materials like titanium and carbon fiber to reduce the vehicle’s overall weight. The aim is to reach an excellent weight/power ratio (lower than 2.9 kg/HP). Moreover, the steel tubular chassis has been reinforced and hardened to provide greater vehicle stability and safety.
