Following the announcement that iRacing members will be able to purchase the Audi 90 Quattro last week, the developers have recently landed another surprise on players of the game, the Nissan GTP ZX Turbo has been made available for purchase! Bringing the second IMSA generation car to the sim, the Nissan GTP ZX Turbo has been made available for purchase with immediate effect. Born of the desire to beat the all concurring Porsche 962, the Japanese factory spent four seasons racing in the IMSA series until clinching its first Manufacturers title in 1989. The '89 season was a successful one for Nissan, and to celebrate that success iRacing have lovingly recreated the car for players to enjoy within iRacing. For those of you how are perhaps less familiar with the Nissan story, iRacing have recorded a nice documentary launch trailer video for the car that can be seen below. The 1989 Nissan GTP ZX-Turbo Launch Trailer: The Nissan GTP ZX Turbo comes to the sim just after the release of the venerable Audi 90 Quattro last week, brining a second vehicle from the IMSA sports car series to the simulation. Several leagues and events are already announced to make the most of these new cars, and sign up has so far been popular with fans. Alongside the new Nissan, iRacing have released a patch for the recent Season 4 build of the simulation, as can be seen below. Change Log - Patch 2 Season 4 Simulator Power saving and screen savers are now turned off when the Sim launches. Connection Fixed a bug that would cause your Options/Graphics/Max cars selection to be sent only to the first server to which you connect while remaining in the simulation. If you registered for a Race session far enough ahead of time and joined the pre-race Open Practice, the Open Practice server would have been told of your selection. But when you clicked on the [Race!] button inside the simulation to transition to the Race session, the Race server would not be told of your selection, and would instead use the default, maximum value. Rendering Windshield reflections have been disabled at night tracks. Fixed an issue where sometimes partially invisible cars would be present with large fields at Le Mans. All floating point exceptions (reporting in .logs and/or crashing out) in the FG and BG have been disabled if the SIM is running on Wine (Mac/Linux). Options Fixed a misspelling in the help text for the Far Terrain setting on the Options screen. Animation Fixed an issue where the lollipop guy would sometimes appear in a T-pose. CARS Aston Martin DBR9 GT1 Season setups have been updated. Tire warmers are now used for this car. Temperature is set to what we would see with blankets or an oven, as used on GT3 cars. Audi Quattro GTO Season setups have been updated. Minor bug fix to the selection of the number of clutch plates for the rear diff. The change increment was two plates, but the range of plates was 1 plate to 8 plates, resulting in strange selection increments depending on where you started. The range has been changed to be from 2 plates to 8 plates. Fixed a car number position issue with the official Audi 90 GTO paint scheme pattern. Fixed the misspelling of FELUERLOSCH-ANLAGE on the dashboard. Chevrolet Corvette C6.R GT1 Season setups have been updated. Tire warmers are now used for this car. Temperature is set to what we would see with blankets or an oven, as used on GT3 cars. Dallara DW12 Road course tire wear has been significantly increased to ensure more realistic degradation. Ford GT A slight reduction in fuel consumption to try to hit target stint lengths. Tire warmers are now used for this car. Temperature is set to what we would see with blankets or an oven, as used on GT3 cars. HPD ARX-01c Added a starter so the engine is able to re-fire if it is shut down when on track. Fixed a distortion issue with the mirror portals. TRACKS Circuit des 24 Heures du Mans Signage and advertisements have been updated. Adjusted several race-control checkpoints. Le Mans is becoming more and more popular; additional crowds and cars have appeared at the track.
