• Dallara remains the exclusive chassis builder with Xtrac supplying transmissions and Performance Friction Corporation providing brake components.
• Engineers plan to shave 85 to 100 pounds from the chassis—led by a 25-pound gearbox weight cut—to boost acceleration and handling.
• The new powertrain features a 2.4-liter twin-turbocharged V-6 complemented by extended hybrid deployment for increased torque and horsepower.
• Safety enhancements include an ergonomic driver cockpit, an integrated aeroscreen and a reinforced roll hoop to improve impact protection.
