And for our USA readers… The Alfa Romeo engineering team recently completed extensive tests of the new 33 Stradale prototype at the Nardò circuit to evaluate its driving dynamics and high-speed performance. The team assessed parameters such as aerodynamics, top speed, maximum temperatures, cooling systems, and cabin soundproofing in preparation for the inaugural delivery in Italy later this December.
The Nardò Technical Center (NTC), located in Salento, Italy, is one of the world’s most advanced testing facilities. Established in 1975 by FIAT, it spans 1,730 acres and features 20 test tracks.
Among these tracks is the Nardò Ring, the fastest circular track globally. It measures 2.5 miles (4 km) in diameter and 7.8 miles (12.6 km) in length. Its design allows drivers to experience balanced centrifugal force on all lanes, creating the sensation of an endless straight drive.
The Alfa Romeo team performed high-speed testing on the developmental 33 Stradale at this ring track, achieving a target top speed of 207 mph (333 km/h) and accelerating from 0 to 62 mph in under three seconds. This performance results from the technicians’ meticulous work on the car’s aerodynamics, ensuring every line of its design optimizes airflow.
The 3.0-liter twin-turbo V6 engine produces over 620 horsepower and is paired with an 8-speed dual-clutch transmission (DCT) that delivers power to the rear wheels, supported by an electronic limited-slip differential. This engine enhances the existing V6 found in Alfa Romeo’s top performance models and is mounted longitudinally for improved performance.
Testing at the NTC follows evaluations at the Balocco Proving Ground in Vercelli, known for developing high-performance racing cars since 1962. A team of Alfa Romeo engineers conducted medium- and high-speed tests focusing on balance, braking, and handling. The initial tests at Balocco assessed the steering precision, brake responsiveness, and handling characteristics provided by the aluminum H-frame, carbon-fiber monocoque, and finely tuned suspension.
The car offers two drive modes: Strada (Road) and Pista (Track), activated via switches on the central console. Strada mode prioritizes comfort with smooth power delivery, standard pedal sensitivity, soft suspension, and active exhaust valves that open above 4,000 rpm.
Pista mode shifts to peak power, providing rapid gear shifts, a rigid suspension, and always-open exhaust valves for a thrilling experience. A standout feature is the Partenza Veloce (Quick Start) procedure, which optimizes the gearbox, traction control, and power delivery to reduce wheel slippage when the Quadrifoglio button is pressed.
During specific sections of the circuit, Alfa Romeo testers turned off traction control (ESC OFF) to test the 33 Stradale at near-top speed. This showcased the car’s ability to blend supercar performance with ease of handling, even for non-professionals. The twin-turbo V-6 creates an engaging ‘mechanical symphony’ that enhances the driving experience.
The active suspension system is vital, offering a balance of comfort and performance through its dual-arm setup with active shock absorbers and semi-virtual steering. This design ensures precise steering control and remarkable handling.
The Balocco session also demonstrated the brakes’ precision across different driving modes. Thanks to the Alfa Romeo Brake-By-Wire system, the 33 Stradale can stop from 62 mph to 0 in under 108 feet. Brembo carbon-ceramic brakes, featuring ventilated and perforated discs alongside six-piston calipers in the front and four-piston calipers in the rear, allow for repeat high-performance stops with minimal fading.
