The simulator was developed by Kunos Simulazioni, a small Italian studio led by Stefano Casillo. The studio pursued a philosophy of uncompromising realism at a time when most commercial racing titles still prioritized accessibility over authenticity. netKar PRO debuted at a fair held in Lanciano, Italy, from February 24 to 26, 2006, and version 1.0 was released for download on April 10, 2006.
To achieve engineering-grade simulation fidelity, Kunos Simulazioni collaborated with a range of companies active in real-world motorsport. Partners included Sparco for the design of steering wheels, helmets, and driving suits; AIM Sportline for fully functional data acquisition systems reproduced within the simulator; Cooper and AVON for tire modeling; Brembo for braking systems; and Beta Tools for workshop equipment. The studio also worked directly with Formula Three outfit Target Racing, alongside race engineer Andrea Quintarelli and driver Riccardo Azzoli, who had competed in Formula Gloria, Formula Renault, and Formula Three.
netKar PRO gave players access to detailed car setup screens covering aerodynamics, brakes, chassis geometry, and transmission ratios. Steering wheel angle and tire air pressure could be adjusted individually for each corner of the car. Telemetry data could be recorded and reviewed at any point, mirroring professional driver workflows.
The tire model was particularly advanced for its era, simulating visible dirt accumulation, tire wear, and flat spots, each of which influenced handling behavior in measurable ways. The cockpit was fully interactive, drawing comparisons to flight simulator standards rather than the superficial interiors common in racing games of the period.
The game shipped with five tracks, with a further 21 available as free downloads. The track roster included both licensed real-world circuits and fictional layouts. Controller support covered USB steering wheels, Xbox 360 controllers, joysticks, and keyboards.
Version 1.1 was developed through a public beta program beginning in August 2009, involving three staged releases to gather community feedback. Beta 1 introduced a redesigned user interface intended to lower the barrier to entry, reworked force feedback, and support for a broader range of input devices. Previous versions had been criticized for requiring USB steering wheels as the only supported controller. Beta 2 added the Abarth 500 Assetto Corse and a new fictional circuit called Aosta. Beta 3 arrived in January 2010 with audio controls, chat improvements, and differential refinements. The 1.1 final release appeared on April 6, 2010.
Version 1.2, released on November 12, 2010, introduced the Formula KS2, a car based on the real-life GP2 single-seater. It also brought a revised tire model, improved differential modeling, better collision handling, and numerous minor fixes.
Version 1.3 was announced in December 2010 and was planned to include a hill climb track at Trento-Bondone with the Osella PA-21, a Shelby Daytona road car, and rain physics with puddle formation. A beta of 1.3 emerged in February 2011, though the final release had not appeared by that point.
netKar PRO holds an important place in sim racing history as the developmental laboratory where Kunos Simulazioni refined the physics and simulation architecture that would eventually become Assetto Corsa, released in 2014. The studio's insistence on working directly with professional motorsport engineers rather than approximating physics from observation set a standard that influenced later independent sim developers. Its small but dedicated community supported the title through active modding and online racing leagues, keeping the simulator alive well beyond the end of active development.
The collaborative industry approach, particularly the integration of functioning AIM data logger systems, was unusual in the consumer simulation space and reflected Casillo's ambition to build a tool credible enough for use by actual racing drivers as a training aid.
