Aerodynamics
Composite materials
The focus on essentials guided Dallara’s material choices for the Dallara Stradale. By eliminating the superfluous, they pushed the boundaries of what is necessary, using carbon fiber composites. The result is a vehicle weighing just 855 kg.
To achieve this, Dallara used pre-preg autoclave processing and long fiber compression molding for the monocoque, a body panel system for the exterior, and carbon sheet molding for reinforcements. Carbon fiber extends deep into the car’s structure, even in hidden components like mounts, levers, and interfaces.
Despite its lightweight design, the Stradale delivers powerful performance, stopping from 100 km/h in just 31 meters, thanks to compact brake discs that lighten the suspension and overall chassis.
Vehicle dynamics
The Dallara Stradale bridges projection and reality, crafted from concrete ideas and refined in a virtual environment using a professional driving simulator. Decades of racing experience allowed Dallara to create an ideal development setting. The simulator, central to the car’s development, enabled engineers, technicians, and drivers to finalize suspension, engine, and ergonomic specifications before production began.
On the road, the Stradale offers a balance of grip and comfort, with optimized front tire contact for direct asphalt connection and rear tire design for smooth obstacle handling, turning every corner into a pleasure. This experience is enhanced by a limited-slip differential, ABS-ESP Electronic Stability Control, and the monocoque’s high torsional stiffness, ensuring top performance and stability.
The Stradale embodies two driving modes: Road, for urban environments, and Racetrack, which lowers the car by 20 mm to maximize its aerodynamic capabilities. Both modes are easily selectable via steering wheel controls, adapting the vehicle to your needs in any situation.
Dallara Stradale EXP
SPECS
Aerodynamics
The Dallara Stradale EXP, a super sports car free from homologation constraints, features a few key enhancements, such as a redesigned carbon rear wing. This, combined with the front diffuser, boosts vertical downforce by over 30% compared to the road-approved Stradale, achieving more than 1,250 kg at top speed and lateral acceleration exceeding 2.7G with slick tires.
This superior aerodynamic performance results from extensive research into the car’s upper body, designed to work harmoniously with the underfloor—drawing on Dallara’s decades of experience, particularly with GT and Le Mans Prototype vehicles. The reinforced front diffuser channels airflow to large side ducts behind the front wheels, utilizing the “elephant foot” feature typical of sports cars.
The underfloor seamlessly connects the front and rear diffusers. The rear diffuser, with its five channels, covers nearly half of the car’s surface and works in sync with the spoiler, wing, and ducts behind the rear wheel arches. The front section of the underfloor features a lowered front diffuser, damage protection with wood surfaces, and multiple aerodynamic elements, including adjustable rear wings, strakes, and louvers.
Inside, the doorless design allows for innovative airflow solutions, maximizing engine cooling efficiency with a layout that mirrors racing cars. The engine intake and air filter are also designed with racing specifications in mind, ensuring peak performance.
Lightness and powertrain
The Dallara Stradale EXP weighs just 890 kg, thanks to the extensive use of carbon fiber composites designed with a “materials and processes suitable for their function” approach. Pre-impregnated carbon fiber is used for the monocoque, long fiber compression molding for structural parts, a body panel system for exterior panels, and carbon sheet molding for reinforcements. Even non-visible, secondary components like brackets, levers, and interfaces are made from carbon fiber. The design prioritizes weight reduction with the belief that “lightness allows lightness,” evident in the compact car body, multifunctional components, and compact wheels, tires, and brake discs, all engineered for high performance.
Powertrain and chassis control
Vehicle dynamics
The Dallara Stradale and EXP were developed using Dallara’s professional driving simulator, allowing engineers, technicians, and test drivers to fine-tune suspension, engine, and ergonomic specifications in a virtual environment before production. The suspension kinematics were optimized for maximum grip and performance on the racetrack, and even the tires were developed on the simulator, leveraging Dallara’s motorsport expertise.
The EXP features new dry slick tires, with optional wet slicks developed in partnership with Pirelli, and racing-style rims with a single nut. Its dynamics were designed to maximize performance while ensuring stability, thanks to high torsional rigidity provided by the doorless monocoque, which resembles a formula racing survival cell. The EXP is also equipped with an advanced shock absorber system, including new valves, a stiffer spring set, and adjustable, stiffer anti-roll bars.
Safety, ergonomics and comfort
The Dallara EXP barchetta model is FIA-compliant and equipped with essential racing safety features, including an FT3 FIA-standard fuel system, fire extinguisher, and emergency switches on the bodywork. For driver protection, it includes a 6-point HANS-compatible seat harness, head protection system, removable steering wheel, brake lines, and towing eye. The chassis features front and rear rollover protection structures. The aerodynamic design and compact shape create a racing car-like driving position, with a detachable driver’s seat and elevated feet for optimal connection to the car.
For added comfort, the EXP is equipped with air jacks and a removable passenger seat with a 6-point safety harness and headrest. The design naturally accommodates the driver, making them feel embraced by the car. The chassis is elevated at the front to provide space for the front diffuser, aligning the driver’s feet higher than the seat, similar to a monocoque design.
An optional windscreen and canopy with gull-wing doors, made entirely of carbon with clear polycarbonate surfaces, can be added for enhanced comfort. Weighing under 35 kg, the canopy is designed to minimize aerodynamic resistance while ensuring maximum visibility, even in adverse weather. The EXP also features an advanced electronic data acquisition system with over 80 logged channels and a HD SmartyCam cockpit camera. This setup allows drivers to capture high-definition videos with live telemetry, helping them refine their driving style and improve performance lap after lap. A TPMS Kit (Tire Pressure Monitoring System) is also available to monitor tire temperature and pressure, ensuring optimal vehicle performance, just like in motorsport.
