rFactor 2 is a computer racing simulator created by the American independent software firm Image Space Incorporated and since 2016 developed by Studio 397 (which was acquired by Motorsport Games in 2021). rFactor 2 was released for Windows in 2012. Like its predecessor, rFactor, it is designed to be modified and is used by professional racing teams for driver training and race car development.[3][4][5][6][7][8][9][10] Much of its source code is derived from rFactor Pro which is also used by professional racers and most of the Formula One teams and NASCAR manufacturers.[11][12][13]
rFactor 2 is designed to simulate any type of multi-wheeled vehicle of any era including four-wheeled and six-wheeled vehicles with either two or four steered wheels. It features an advanced physics, suspension, and tire model.[14][15]
Background[]
After the initial success of Sports Car GT (1999), Image Space Incorporated used its self-developed software engine isiMotor1 for a number of racing titles, including the highly praised Formula One simulators F1 2002 and F1 Challenge '99-'02. isiMotor is an umbrella term that covers every component of the software engine,[citation needed] for example the graphics engine gMotor, the physics engine pMotor,[16][17] and so on.
After the release of F1 Challenge '99-'02, isiMotor was licensed to another company for the first time, SimBin, who went on to produce popular retail sim racing titles based on Image Space Incorporated's engine, including GTR and GTR 2.
Image Space Incorporated then decided to make a racing simulator with an open architecture and provided tools for the modding community to create third party content. This title became rFactor which was the first ISI release using the software engine referred to as isiMotor2. rFactor went on to become the preferred racing simulation platform for nearly a decade, with a plethora of community created content.
isiMotor2 was further licensed to companies such as Slightly Mad Studios, and . isiMotor2 also laid the foundation for rFactor Pro, a software simulation engine used by real life racing teams and car manufacturers including most of the current Formula One grid and NASCAR manufacturers. Image Space Incorporated took the experience from isiMotor2 and rFactor Pro and began the development of rFactor 2. From this point on, the software engine would be referred to as isiMotor2.5.
Development[]
From announcement to open beta (2009-2012)[]
The public first became aware that the development of rFactor 2 was underway when Gjon Camaj of Image Space Incorporated posted WIP in-game screenshots on Twitter in early March 2009.[18] Later that month, he revealed more details about the upcoming simulator alongside additional in-game screenshots. In October 2010, Camaj revealed in an extensive interview plans for including licensed content, a new reworked UI, inclusion of dynamic weather, new innovative dynamic racing surface technology, improvements to the AI logic and a new force feedback system with lower input lag and much faster and more direct steering rack forces, along the lines of the popular third party developed RealFeel plug-in for rFactor.[19]
In December 2011 more features were confirmed to be included in the upcoming open beta, including rain, wet/dry track transitions, dynamic track elements (groove/marbles), new tire model, new physics and a new collision model.[20] On January 10, 2012, the first open beta (Test Build 49) was released[21][22][23] and after the December 20, 2012 release (Update 10, Build 134)[24] it went out of beta since early 2013,[25] and the official Steam store page retrospectively lists it as released on March 28, 2013 (which corresponds to build 198).[1]
Development by ISI after release (2013-2016)[]

On September 16, 2016 at , ISI announced a partnership with Dutch software company with the goal of bringing new features to the software.[31][32] Luminis already had experience with racing simulators having supported Reiza Studios in the development of . This partnership brings the development of rFactor 2 in a new company called Studio 397, based in Apeldoorn, the Netherlands. Studio 397 managing director Marcel Offermans stated that a lot of new features will be implemented in the game, including a more web-based UI, a DirectX 11 compatible graphics engine and the VR support for Oculus Rift and HTC Vive. Moreover, a new "paid-content system" would allow ISI to add more licensed content to the simulator.[31][33][34][35]
In October 2016, Studio 397 released information about the new content. The developers announced they have acquired the license of U.S. F2000 National Championship, Radical Sportscars and NOLA Motorsports Park.[36][37] The new rFactor 2 version will be available only on Steam.[36][37] With their first build release, in December 2016, Studio 397 made online racing free to all users, removing the previous subscription fee model.[38] In May 2017, the open beta for the DirectX 11 graphics engine was released,[39][40] and it became the default one later the same year, discontinuing support for DirectX 9.[41] With DX11, also support for Virtual Reality was introduced.[42]
From July 2017, Studio 397 started to release a series of updates to the tyre model, starting with the Radical SR3 RSX,[43] and continuing with a contact patch model (CPM) update in October of the same year.[44] In December 2017, a new build introduced an update to the tire contact patch model (CPM) physics, which developer Michael Borda deemed "the biggest change in rF2 since the introduction of the contact patch model" (which was with the 880 build back in 2014).[45][46] The updated CPM was also available to modders, and was used for instance in the 2018 version of the GP3 Series mod.[47] In 2018 Studio 397 conducted tests at the Mechanopôle test track in Alès (France), in collaboration with Duqueine Engineering and Indy Lights and LMP2 driver Nicolas Jamin, to fine tune physics and tire data for the LMP and GTE cars.[48] In February 2020, further physics update were released, based also on feedbacks from 2017 World’s Fastest Gamer winner Rudy van Buren.[49]
As of new content, in August 2017 Studio 397 released the first paid DLC for rFactor 2, with the McLaren 650S GT3,[50] followed in October by a larger GT3 pack DLC.[51] The following month the first Formula E content was released.[52][53] In March 2018 the KartSim DLC package was released, containing two go-karts and three tracks.[54][55] In February 2018, Studio 297 finished data gathering for the first laser scanned track for rFactor 2 (Sebring), using Lidar technology.[56] Later in 2018, Studio 397 released the Endurance package and some historical F1 cars (the Brabham BT44B, March 761, and McLaren M23, MP4/8 and MP4/13).[57][58][59] In June 2019, the first six Tatuus-based cars were released.[60]
In January 2019, rFactor 2's physics was licensed to Amazon Game Studios' The Grand Tour Game.[61]
As of 2021, development is ongoing to add an online competition system, which is currently in beta and features some esports series including the BMW SIM M2 CS Racing Cup, the Formula Challenge and the GT Challenge.[62] In July 2021 the "Linked Sessions" feature was introduced.[2]
On March 3, 2021, Motorsport Games announced a deal with Luminis International for the acquisition of 100% share of Studio 397 and rFactor 2 for 16 million USD.[63] The acquisition was completed in May of the same year. In February of the same year, Motorsport Games also acquired Black Delta, developer of , for an undisclosed amount.[64][65] In July 2021, Motorsport Games confirmed that, discontinuing its NASCAR Heat series, it will be using the rFactor 2 physics engine and the Unreal graphics engine for the upcoming NASCAR 21: Ignition, due later in 2021.[66] The combination of the rFactor and Unreal engines will also be used for all the upcoming titles produced by Motorsport Games,[66] like the British Touring Car Championship game due in 2022, and the official IndyCar Series game due in 2023.

Physics[]
rFactor 2 and its precursor have received much praise for its highly advanced and accurate simulation of vehicle dynamics and is the preferred simulator for most real life professional racing teams, car engineers and simulation centers. rFactor 2 is also being used to train the drivers who win the Gran Turismo Academy competition.[3][8] rFactor 2 also includes a new constraint system that allows for advanced physics simulation such as chassis flex, which removes the typical infinite rigidity of a virtual vehicle and incorporates unique chassis characteristics into the handling and performance of the car[67] as well as highly accurate suspension geometry and wheel rates.
Race Engineer Andrea Quintarelli stated: "It is also no surprise for me that most of these professional simulators (or centers) are using rFactor. As I had the chance to prove myself (and probably to somebody reading here), when you know how to properly build your models, rFactor is producing very accurate results, at a very low cost".[4]
Petros Mak, founder of the professional modding company Mak Corp, stated: "All our race team clients and even our series clients, they don't only use rFactor for track familiarization. They also use it to test setup data before they go to an event, they use it to test potential new part data, by developing new brakes or new engine performances and testing it in the game before they actually commit to building it in real life. rF1 and rF2 provide far higher accuracy for those things than any other simulation on the market. [...] rFactor 2's physics engine is by far the most simulation based physics engine using real life aero and physical data that no other title has come close to".[7][10]
The editor from the sim racing site VirtualR stated: "It took me some time to see it but I do recognise rF2 as the best racing sim out there for the serious players".[68]
Tire model[]
The interaction and collaboration between Image Space Incorporated and professional racing teams and their engineers using the ISI developed rFactor Pro platform has benefited the new tire model used in rFactor 2. This has resulted in the ISI TGM Tyre Tool,[69] a tool that is also available to third party modders.
rFactor 2 is the first consumer simulation featuring a thermomechanical[70] physically-based tire model, based on first principles,[71] simulating the entire carcass, thread and contact patch, with proper heat transfer,[72] accurate tire wear, flatspots[73] and visual deformation.[74][75][76] It is also the first to feature truly dynamic track conditions.[77]
Most people new to rFactor 2 including experienced simracers are not used to having to manage their tires like in reality, therefore they tend to overdrive the car with too much steering input (something you can get away with in other driving simulations), resulting in overheating tires and excessive tire wear.[78]
rFactor 2 also features realistic tire wear[79] and damage. This punishes the player for locking up the brakes because a flatspot will occur with force feedback vibrations (tire suddenly has edges instead of being perfectly round) and a car imbalance (due to the lost weight of the burnt off tire). Until the tires are changed during a pit stop, the car will feel imbalanced and uncomfortable to drive. Using bad driving techniques will also punish the player with tires overheating and wearing unevenly. Tire punctures are also featured though not visually represented in-game.
Real Road[]
Real Road is one of the most prominent features of rFactor 2.[80] Rubber is dynamically laid on the track surface in real time during a race session by the player and the AI. The rubber can carry over to the next sessions and this calls for the player to constantly having to adapt to the advancing track conditions during a race weekend which in a dry race weekend means more and more available grip throughout. The player can choose from various rubber presets to start with or just choose to start the weekend on a completely green track. Real Road can be accelerated, left at a normal rate, or be completely static. The feature also creates grip-affecting marbles outside of the normal racing line.
Real Road also works together with wet weather. When rain hits the track, the previously built-up rubber and marbles is washed away and the track will then need to be rubbered in again. The wet track surface dries dynamically similar to the aforementioned rubber build-up due to both cars on track, resulting in a drying line,[81] as well as temperature, sun and wind. The Real Road system of rFactor 2 is unique because it is not scripted, but completely dynamic.[77]
AI[]
The AI of rFactor 2 is highly advanced and much improved over the first rFactor. It has spatial awareness, adjustable strength and aggression sliders and has the ability to "learn" better racing lines around a track resulting in better lap times. The AI can also be allowed to take control over the player's car. rFactor 2 is unique in that it is capable of races with over 100 AI opponents[82] and you can also mix AI opponents with real drivers during online multiplayer races.
Modding[]
rFactor 2 is designed specifically to be modified. It is the first race sim with a dedicated mod packaging system and with the Steam release it will be the first with Steam Workshop integration.

Also featured in rFactor 2 is a full day-to-night cycle with lighting transitions which can be set to real-time or accelerated. Fuel usage and visual as well as mechanical damage are also featured in the simulator, along with a "resume from replay" feature where any saved replay can be loaded and the player can then choose to resume driving at any point during that replay.
Use in official esports events[]
From April till June 2020, rFactor 2 was used for the Formula E Race at Home Challenge.[83] On June 14th rFactor 2 was used for the 24 Hours of Le Mans Virtual race, organized in collaboration with Motorsport Games.[84] The race was red-flagged twice when the server had a problem and had to be restarted, drawing criticism from race-leader Max Verstappen.[85][86]
Since 2014, rFactor 2 has also been used for the FSR World Championship organized by the International SimRacing Club.[87]
