Dallara Automobili Stradale: atomica (ma costosa!)[:en]The new Dallara Stradale revamps the “barchetta” stlye allure
L’ECCELLENZA AUTOMOBILISTICA ITALIANA HA UN NUOVO PORTABANDIERA: LA DALLARA STRADALE. C’E’ IN LEI UN MISTO DI DIVINITA’, HERITAGE E DI FUTURISMO, FUSE IN UN’AMALGAMA PERFETTA. SE ANCORA SI POTESSE CORRERE LA “VERA” MILLE MIGLIA, PROBABILMENTE LEI SAREBBE LA FAVORITA’. FIGLIA DELL’EXPERTISE DELL’AZIENDA ITALIANA NEL MONDO DELLE COMPETIZIONI (IN TUTTO IL PIANETA!) E’ STATA SVILUPPATA DA MARCO APICELLA E “SUA MAESTA'” LORIS BICOCCHI. HA UN UNICO DIFETTO: COSTA PARECCHIO!
La quadratura del cerchio della carriera professionale dell’ingegner Giampaolo Dallara (classe 1936, ex-Ferrari, ex-Maserati, ex-Lamborghini) è finalmente stata raggiunta con la produzione della prima vettura stradale completamente a marchio Dallara. Naturalmente, nel pieno rispetto della filosofia aziendale, la Dallara Stradale è un’auto capace di circolare su strada normale unicamente nella misura in cui è targabile. Ma, ovviamente, siamo di fronte a un vero e proprio laboratorio con le ruote, con tante possibilità di personalizzazione e di configurazione (dal punto di vista tecnico!).
IL CONCETTO
Dallara è azienda leader nel mondo (telaio/carrozzeria della Bugatti Chiron, telaio dell’Alfa Romeo 4C, telaio delle monoposto di Formula Indy). Mancava, al suo portfolio prodotto, un oggetto che desse, ancora una volta, dimostrazione della tradizione italiana con le vetture GT.
La Dallara Stradale è una barchetta biposto senza porte, realizzata a partire da una scocca in fibra di carbonio con carrozzeria in compositi. Lo studio della forma di carrozzeria è stato sviluppato in galleria del vento per ottenere volumi efficienti e orientati a massimizzare le prestazioni. In condizioni di utilizzo normale, quindi, la vettura sviluppa accelerazioni laterali di oltre 2 g. Secondo il costruttore, il peso (a secco) è di soli 855 kg, un valore che corrisponde a un rapporto peso/potenza di 2 Kg/Cv.
MOTORE, TRASMISSIONE, TELAIO
Il motore, in posizione centrale, è un 4 cilindri di 2,3 litri con turbocompressore di provenienza Ford Ecoboost. Sviluppa 400 cavalli ed è abbinato a controllo di stabilità ESP Bosch (che include ABS-EBD-TCS-VDC). Il cambio, di serie, è un meccanico a 6 marce ma è possibile optare per un robotizzato a 6 rapporti con due logiche di gestione (sia in funzionamento manuale, sia automatico): Normal e Sport.
CARROZZERIA
La Dallara Stradale in versione “base” è una barchetta senza portiere. Da questa configurazione iniziale sono possibili differenti modifiche: aggiunta di un parabrezza che la trasforma in roadster, aggiunta di una struttura T-Frame che la trasforma in Targa, aggiunta di un cupolino che chiude l’abitacolo (dotato di porte ad ala di gabbiano). Per un utilizzo principalmente in pista, infine, il cliente può richiedere il montaggio di un pacchetto aerodinamico con grandi ali stabilizzatrici.
PRESTAZIONI E PREZZO
Il costruttore dichiara un tempo di 3″45 sullo 0-100 e 280 km/h di punta massima in configurazione base.
Il prezzo iniziale della Dallara Stradale è di 155.000 € chiavi in mano, tasse incluse (per il cupolino “Gullwing” sono necessari altri 32.000 Euro). La vettura, già in vendita, ha già un numero autorevole di clienti vip: Jean Alesi, Paolo Barilla e, si dice, Sergio Marchionne. La capacità produttiva dell’azienda parmense è di una decina di esemplari al mese.
Le consegne sono già iniziate: Giampaolo Dallara ha preso in consegna il telaio numero 1, una barchetta in colore giallo. L’Amministratore Delegato di Dallara Automobili, Andrea Pontremoli, ha preso in consegna l’esemplare numero 2 (colore blu) mentre le vetture numero 3 e 4 sono state consegnate ad altrettanti sconosciuti clienti.
THE DALLARA STRADALE IS A DREAM NURTURED ON RACETRACKS ALL OVER THE WORLD. THE RACING TECHNOLOGY APPLIED TO THE PLEASURE OF DRIVING. A UNIQUE PRODUCT, DESIGNED TO ENHANCE THE COMPANY’S KEY SKILLS: CARBON FIBER STRUCTURES, AERODYNAMICS AND VEHICLE DYNAMICS.
The first model of Dallara Stradale was handed over to its owner on the day of his birthday. Giampaolo Dallara, a life as an Engineer, went out to drive the street-legal Dallara right from the building in which he started his business activity 45 years ago in Varano de’ Melegari, not far from the house where he was born on November 16,1936.
In 2015, after a long processing period, twenty engineers and five mechanics were entrusted to a Technical Director: Giampaolo Dallara. The goal was clear: making a car to rediscover the real pleasure of driving on the road or on the track. “I like to think that Colin Chapman, which I began to admire since the days of his Lotus Seven, would appreciate the essentiality and simplicity of this car,” says Mr. Giampaolo Dallara, President of Dallara Automobili. “This project,” adds Mr. Dallara, “sums up everything we learned from racing and from collaborations with our clients, and I am convinced that those who will use this car will be able to try the pleasure of driving for the sake of driving. They will get in the car to take a nice ride and to experience the pleasure of driving”.
PRODUCT
In the base configuration, the Dallara Stradale is a barchetta without doors, like a single-seater racing car. It can be customized in a roadster configuration with the addition of a windshield. Adding a T-Frame, the car becomes a targa. With the further addition of two doors with a seagull wing opening, the car becomes a coupe. For those who want to use the car mostly on track, there is the possibility to install a rear wing, which provides access to exceptional levels of downforce.
The car customizations in terms of performance are not limited only to the addition of the rear wing, but it is possible to install adjustable suspensions which allow to lower the car in track set-up, guaranteeing a high comfort standard in any condition. The Dallara Stradale provides a six-speed manual transmission, but among the optional equipment a “paddle-shift” system is provided for the robotized gearbox which minimizes the time shifting, equipped of two methods and two different mappings, automatic: Normal and Sport; and manual: Normal and Sport.
Thanks to its low weight, an accurate study of vehicle dynamics and high aerodynamic load, the performance is of a true racing car.
• Its 855 kg as a total car weight are a result of the extensive use of composite materials and carbon fiber. The logic behind materials and processes is “materials and processes suitable for their function”: pre-impregnated in an autoclave for the monocoque; long fiber compression moulding in structural components of the bodywork; body panel system in exterior panels; carbon sheet moulding in reinforcements.
• The kinematics of the suspensions and the calibration of springs and bars and dampers have been defined to maximize the compromise between grip and comfort. Dynamic characteristics of the vehicle have been set, developed and defined in numerous sessions at the Dallara Driving Simulator: expert test drivers have worked closely with technicians and engineers to define the specifications of the suspensions, aerodynamics, engine and ergonomics suitable for an exceptional driving pleasure.
• Thanks to the virtual development of the CFD and several Wind Tunnel sessions, the aerodynamic load coefficient obtained allows obtaining vertical load values (downforce) among the highest between GT roadcars (more than 820kg @ TopSpeed).
The combination of weight, vehicle dynamics and aerodynamics, along with customized tyres, allows to reach lateral accelerations beyond 2G under normal conditions of use.
The Dallara Stradale is equipped with the latest Bosch ESP stability control systems (which includes ABS-EBD-TCS-VDC) to ensure an excellent control of the car in all conditions of use.
The powertrain is a 4-cylinder 2.3 L supercharged capable of delivering 400 HP, the result of an accurate selection and optimization of engine components, combined with the electronic control system developed in close collaboration with Bosch.
The first prototype was presented on 16th November 2016, when Mr. Dallara turned 80 years old. Since then, the road testing activities have begun, with car homologation and production equipment setting.
On that same day, but one year later, on 16th November 2017, the deliveries of the Dallara Stradale begin, as promised one year ago.
PARTNERSHIP
The Dallara Stradale was developed in close cooperation with Bosch, which was part of the Dallara team working on the project and was responsible for the development of vehicle and engine electronic control systems and has certified their reliability. Bosch’s contribution began with the first engine bench test cycles and continued in all subsequent testing phases on prototype vehicles. Bernhard Bihr, President Bosch Engineering GmbH: “Since the very first day working with the Dallara , what impressed me the most was the passionate and professional yet modest approach in transferring the technology and spirit of a race car into a pure sports car. The effective cooperation between Bosch and Dallara made this development possible in a very short time. We are glad and grateful that we could take part in making this life-long dream of Giampaolo Dallara come true.”
The collaboration with Pirelli has allowed to develop a tyre with the driving simulator before the realization of the prototypes, benefitting from the knowledge of Motorsport and Roadcar sectors, creating a real synergy between the two worlds. The front tyre footprint is optimized to let the pilot feel a direct connection with the steering kinematics, transferring all the feelings to the steering wheel and making the steering torque and driving precision more complete. The rear tyre has been designed to ensure maximum lateral acceleration performance while maintaining a good level of comfort in terms of impact on obstacles and relative damping of the asperity. In addition, the use of the state-of-the-art polymers with dedicated structures has made allow to customize tyres aligned with recent Green Mobility technologies. Stefano Bizzi, Head of Ultra High Performance R & D Pirelli: “We are very satisfied with this collaboration and we are willing to continue to collaborate with Dallara in all the fields where it excels, not only with regard to race cars, but also road cars now.”
The car style was made in collaboration with Granstudio of Lowie Vermeersch. “Giving the shape to the Dallara Stradale was really like translating Giampaolo Dallara’s dream into a sculpture,” says Lowie Vermeersch. “A dream rooted in the timeless beauty of his Miura and nourished through a long career full of passion for racing. For this reason we have avoided a pre-established stylistic idea. As a result, the shape has evolved naturally during the project, in continuous interaction with the engineers at Dallara, and was driven by a clear sense of elegance and harmony in the proportions. This is why we tried to mix beauty and performance in a design that could express genuineness. The car has thus become not only a dream come true but also an expression of what we consider one of the fundamental values of Dallara”.
The testing of the car was entrusted to two Italian drivers, Marco Apicella and Loris Bicocchi, to validate the two souls: performance and comfort. “For some time now, Mr. Dallara has been telling me: ‘Loris, when we find the time to make our road car, I would like you to test it for us. I penciled this in since then“ says Loris Bicocchi. ” I am honored and proud to be part of the development team of the Dallara Stradale for it was a dream for me as well. I have always admired Mr. Dallara, since I saw him for the first time at Lamborghini when I was 17 years old. The shape of the Stradale makes how much they worked on aerodynamics. In fact, from the first laps on the track I realized that it represents what Dallara cars are well-known for: a stiff chassis, top-quality kinematics and suspensions and an aerodynamics that you begin to feel at 60/80 km per hour. On the road, it passes through deformations, humps and holes without affecting the steering wheel and it maintains a high comfort level. Fast but safe: stability, traction and braking controls seldom intervene. It is amazing” adds Bicocchi ” because it lets you drive and does not give you anxiety: it has a great performance both on the mountain roads and on track. It has a brilliant engine, and its the light weight allows an authentic Supercar performance”.
