- 100% Independent Sim Racing News – First Interlagos Video + Release Date

iRacing has released a first preview video of the Brazilian Interlagos track that is in the pipeline to join the online racing simulation.

iRacing has released a first preview video of the Brazilian Interlagos track that is in the pipeline to join the online racing simulation.

Interlagos will be available for purchase starting tomorrow, until then iRacers can shorten the waiting time by watching the video below.

Located in suburban Sao Paulo, Interlagos is officially known as Autódromo José Carlos Pace. The 2.677 mile circuits incorporates 15 corners and has hosted the final race of the Formula One World Championship in numerous seasons.

    Very nice.

    Though kerbs look kinda low and when the Williams car goes over them no suspension movement is evident.

    • Anonymous

      Look at 1:22. That is a proper suspension movement.

      • Big Ron

        I guess, he means onboard-view. There, indeed, is nearly no suspension movement noticable.

      • Anonymous

        Maybe he compares the kerbs with the GSC ones. That was the best reproduction of Interlagos, but this one is laser scanned. To me is just weird the staff making kerbs lower than what they are in realty… Hope you can understand what I mean 😉

        I meant the actual kerbs, comparing to real f1 car they look very flat in iRacing. Also when real F1 car goes over kerb there is lot and lot more vibration then iRacing.

        in iR there isn’t the shacking camera like on realty! btw if you check on telemetry you can see the suspension movement. For me that is the most important thing.

      • Anonymous

        Yeah, the shaking camera is probably some of it. I use the Motion Cockpit View for some subtle addition of that, and would like to see it available in default cameras as well.

      • daz

        The kerbs in places at Interlagos don’t look all that ‘high…

      • Anonymous

        Isn’t that because the Williams has an incredibly stiff front suspension? Not that it might not be totally accurate, but the FW31 should likely have some of the least front suspension movement of any iRacing car. The Skippy for example has incredibly noticeable suspension movement.

      • Big Ron

        Yes, Formula 1-cars are very stiff, but they still have suspension movements. I mean, you can see the movements in the exterior cam, but just not onboard which isn´t the biggest deal, just what I think mfcfan said.

  • gt3rsr

    I’d expect a better driving for a demonstrational video 🙂

    • TomoMeglic

      He probably still drive better than you do programming he, he

      • gt3rsr

        I can code a bit. Not much, but still better than how ‘he’ is driving.

      • Big Ron

        What´s wrong with the driving? Doesn´t look too bad and good enough for a presentation.

  • Anonymous

    In case anyone missed it, you can hear the transmission flexing in the video 🙂

    • Michael Hornbuckle

      I didn’t hear anything different but good for you.

      • Anonymous

        It would help if the car wasn’t covered up by that music 🙁

        Just welcome to hear a little bit of dynamics to the sound after so long of just being bland vanilla and predictable.

  • Justin Schmidt

    how old is the scan? theres a new grandstand with a big roof on the s/f straight for two years now but i dont see it in the video.

    • Anonymous

      They did the photography in early 2011, which was just before a few minor changes. I’m not sure if anything changed intentionally on the racing surface, just nearby objects and runoffs and tire walls I believe. The correct answer would be ‘whenever the contractor scanned it last’, so since they’re usually working with F1 teams and most of the changes for the last few years have been off the racing line that likely explains why it’s out of date a bit.

    Looking forward at the purchase, only it seems they borrowed the clouds from their version Spa. Or they look very similar.

    • Mr Banana

      They need a new cloud model NCM asap!!

    Release notes went up before the site went down this time 🙂

    • Marcos Sanz

      where can I see them? the site is down now…

      • Anonymous

        I submitted them to Montoya, and I’ll put them in this post too.



        – The number of cars that can be used in a hosted, league or
        Tournament multi-car session has been changed from 3 to 4. The frame
        rate and performance in a session with this many cars will depend upon
        your pc and hardware.

        – You no longer need to own all of the cars in a hosted multi-car
        session to participate. You now only need to own the Track where the
        event is being held and one of the Cars in the session. You will only
        be able to drive in a car that you own and you still must meet all of
        the other criteria of the session. You will need to download the cars
        you do not own. This update applies to Hosted, League and Tournament

        – Please Note: The “League Sessions” page and the “Hosted Racing –
        Join a Race” page are the only places on the site that support this
        functionality at this time. We are still working hard on implementing
        this functionality for helmet pop-ups and the “Spectator Sessions” area
        of the site.


        – The downloads page has been updated to support the downloading of
        cars that you have not purchased, that may be required to participate
        in a multi-car hosted events where you only own one of the cars. Cars
        that you do not own, that you do not have installed on your machine will
        appear in a new section of the download page call “Optional Unowned”.

        New Awards

        Nine new awards have been added.

        – Young Star – win official races in four different cars

        – Honorable – win official races in eight different cars

        – The Feared – win official races in sixteen different cars

        – The Alien – win official races in all cars

        – Runnin’ Down a Dream – win official races on four different tracks

        – On the Road Again – win official races on eight different tracks

        – The Long and Winding Road – win official races on sixteen different tracks

        – I’ve Been Everywhere – win official races on all tracks

        – Photo Finish – win an official race with a margin of one
        twentieth of a second or less; this award is not granted retroactively

        License Banner Update

        The License Banner has been completely redesigned for clarity and visibility.

        – The color of your license will change to reflect your License Level.

        – You can toggle between road and oval licenses by clicking “Road” or “Oval” in the top -left area.

        – You can toggle between iRating and ttRating by clicking “iRating” or “ttRating” below your name.

        – Calendar, MPR and Credit maintain their existing functions, but have been restyled.

        – Ping has been moved to the sub-navigation next to “Support”.

        Payments with PayPal Billing Agreements

        ** This section is awaiting a configuration change from our payment partner – we expect within the week.

        – The iRacing Member’s site now supports PayPal Billing Agreements.
        Once you have a billing agreement in place you can renew your account
        automatically, purchase content and recharge your account without
        logging into the PayPal site. A billing agreement is setup
        automatically whenever a member purchases a subscription using PayPal.
        You can also configure a billing agreement without purchasing a
        subscription by going to the “My Account” page on the Member’s site
        (look for the link inside the “PayPal Billing Option” section of the

        – From the “My Account” page you can remove an existing billing
        agreement (look for the link inside the “PayPal Billing Option” section
        of the page).

        – If you have both a PayPal Billing Agreement and a credit card on
        file you should visit the “My Account” page and select your preferred
        payment method for auto-renewals and instant recharges. The link for
        this is located in the “Billing & Shipping Information” section of
        the page.

        – Additional enhancements to this page are links to remove your
        credit card on file and to cancel auto-renewal (this was moved from the
        Cancel / Renew Membership page).

        The following areas of the site have had a visual redesign

        – “My Account”

        – “Account Recharge”

        – “Gift Card”

        – “Promotions”

        Bug Fixes

        – Spotter passwords can no longer be blank. You must uncheck “Require a spotter password” if you decide not to have a password.


        Tilt / Touch Driving

        – Added tilt sensor support to the existing touch driving controls.
        Now you can choose to use a tilt sensor to control steering or
        gas/brake or both. The sensor auto calibrates based on your device
        orientation at startup, but there is a ‘recenter’ button on the driving
        screen (also mapped to the ‘y’ key) that will let you change your
        orientation at any time. The tilt sensitivity can be adjusted in the
        black box along with the FFB sensitivity and touch sensitivity. And the
        throttle and brake can be inverted with an option in the setting tab.

        – Fixed a bug in touch that caused touch up events to get lost if you released your finger over another control.

        Text Chat Macros

        – Added in an ‘auto chat’ feature that lets users hit 10 different
        hotkeys to auto transmit a chat message. By default the keys are mapped
        to the 0-9 keys above your keyboard, but that can be remapped as
        needed. The default messages can also be edited in the sound settings
        tab. Adding a ‘$’ symbol to the end of a line will automatically send
        the chat message for you, without it the message will be left waiting
        for you to edit or send as you wish.


        – No longer report connecting admins as being admins, or show Join/Leave announcements for spectators that are admins.

        – Spectators don’t need to do tech inspections in a fixed setup session.


        – Gray out driving controls and aids that are not used in the
        current session. But still let the user set their preferences for
        future sessions. This includes indicating if the h-pattern shifter will
        be active or not, based on your car type.

        – Remove a lot of text from the controls page and push it into mouse over tool tips in order to improve visual clutter.


        – Change to not do tech inspections on spotters’ machines.

        – When you use the [Start Spotting] button, you will now see the
        live action, instead of the slightly delayed replay tape. You can still
        use the replay controls to rewind and review action from the past. To
        get back to the live action, use the “fast forward to end” button
        (>>|), or simply fast forward and the replay will stop and switch
        to live action when the end of the tape is reached. While spotting, you
        can tell that you’re seeing the live action when the playback state
        says “Live”.

        Camera Tool

        – Allow the camera tool hotkey to be remapped (ctrl-f12) to provide better compatibility with laptops and Mac devices.

        – Fixed a bug where you could not edit the camera shot aim type if your custom camera file ended in ‘’


        – Add lap information to telemetry. (LapBestLap, LapBestLapTime, LapCurrentLapTime, LapLastLapTime)

        – Add delta time information to telemetry. (LapDeltaToBestLap,
        LapDeltaToBestLap_DD, LapDeltaToBestLap_OK, LapDeltaToOptimalLap,
        LapDeltaToOptimalLap_DD, LapDeltaToOptimalLap_OK,
        LapDeltaToSessionBestLap, LapDeltaToSessionBestLap_DD,
        LapDeltaToSessionBestLap_OK, LapDeltaToSessionOptimalLap,
        DD, LapDeltaToSessionOptimalLap_OK)

        – Add radio channel information to telemetry, see the “RadioInfo:”
        section in the session string, and RadioTransmitCarIdx in the telemetry

        – Add pit service time to telemetry. (PitRepairLeft, PitOptRepairLeft)

        Race Control

        – Qualifying laps will now be invalidated if any 0x or 2x car contact occurs during the lap.

        – Many non-significant race control rules are no longer active once
        you finish your race. This could confusingly penalize people after they
        finished their race and cause their finishing position to drop as the
        post-race penalty was applied.


        – We have updated how we draw extra track surface details so they
        conform correctly to the road surface better and render more
        efficiently. This gets rid of our good old “floating skid marks” that
        we’ve come to know and love/hate.

        – As part of the track detail improvements the race track’s surface
        is now always converted into a set of static meshes and stored in video
        memory. The old option to convert it on the fly, which had the benefit
        of utilizing slightly less video memory at the cost of performance,
        has been removed from the graphics options screen.

        – Every car has had its paint adjusted to improve how paint will
        reflect more at low incident angles than when directly facing the

        – Windshield glare at night is much reduced down to a reasonable level.

        – Fixed a bug that was preventing the brake rotor glow effect from being visible.

        – The sim can now reload custom car textures with the ctrl-r
        hotkey. This is useful if you like painting your own cars by being able
        to quickly load and see your work in progress paint scheme without
        having to reload the sim many times. When reloading is triggered, all of
        the existing paint jobs are immediately unloaded and will default to
        white. They will then begin automatically reloading one at a time.
        Reloading happens in the background. If the loading causes performance
        issues while you are driving on track you may disable from loading while
        you are in car via the “LoadTexturesWhenDriving” setting in the
        renderer.ini configuration file.

        – Also, it is possible for an external application such as Trading
        Paints to tell the sim to reload car textures by sending
        irsdk_BroadcastReloadTextures using the SDK.

        – Shut off the auto rotate display feature in Windows 8, and force
        orientation to landscape. Use app.ini [Graphics] displayRotateMode=1 to
        override the default screen orientation.


        – DSD and Lionel Racing sponsors added.


        – Cold brakes now squeal until they warm up, unless the car has
        carbon brakes, which don’t squeal. Note: the sim still does not model
        any brake performance changes with temperature at this time.

        – Engine sound power now continues to get louder as rpm nears max.

        – Fixed a bug in the opponent cars that would make them sound like
        they were driving around at full throttle even while coasting or hard

        Flexible Drivetrains

        – All cars now have flex modeled in their drivetrain math, instead
        of being perfectly rigid. This gives all kinds of subtle and interesting
        audible and physical engine rpm wobble effects. Note: our model of the
        detroit locker differential that many of the oval cars use can cause
        some pretty rough sounding off throttle rpm bouncing as the locker and
        drivetrain get into a oscillation as the locker clatters between driving
        the left or right wheels. We’re looking into that.

        New Tire Model

        – There have been improvements to the modeling of the tire carcass
        motion, which improves the handling on all the cars. All our NTM cars
        feel much better with this tire model update, and have had some amount
        (anywhere from a little to a lot) of re-tuning, so even if a car doesn’t
        have its own release note does not mean that you shouldn’t try it out
        to find out how it drives now!

        – Tweak skid widths, smoke and skid amounts.

        New Steering Model

        – All the cars have better constrained steering systems to go with the tire carcass improvements, giving more precise feel.


        – Road course and oval drafting have been reworked to improve the racing experience.

        Chevrolet Impala

        – New rules limit track bar split left to right to a maximum of 3″ at all tracks.

        – Right rear underbody collision surfaces have been lowered to hit the ground after the proper amount of compression.

        Chevrolet Impala Class B

        – New rules limit track bar split left to right to a maximum of 3″ at all tracks.

        Chevrolet Monte Carlo SS

        – Fixed cockpit view windshield duplication when the car was damaged which caused double darkening and reflection issues.

        Chevrolet National Impala

        – New rules limit track bar split left to right to a maximum of 3″ at all tracks.

        Chevrolet Silverado

        – New rules limit track bar split left to right to a maximum of 3″ at all tracks.

        – Right rear underbody collision surfaces have been lowered to hit the ground after the proper amount of compression.

        – Logitech sponsorship on the windshield has been removed.

        Ford GT

        – This car has had a physics overhaul to improve how it drives.

        Ford Falcon V8 Supercar

        – Added new exterior engine sounds that better capture listening at
        a distance. The previous exterior sounds are now only for the on-car

        Mazda MX-5 Cup and Roadster

        – Nvidia sponsorship has been removed.

        McLaren MP4-12C GT3

        – In-car ABS controls are now available to be assigned, in addition to the usual black box method of adjustment.

        – Updated the rpm mapping for Logitech G27 shift lights.

        Radical SR8

        – Updated the rpm mapping for Logitech G27 shift lights.

        Autódromo José Carlos Pace

        – This classic Brazilian race track, also known by its former name Interlagos, is now available!

        Bristol Motor Speedway

        – Update GPS position. It was off by 10 meters or so, and had been 30 meters too low.

        Circuit de Spa-Francorchamps

        – Improved the Endurance configuration surface types near La Source to try and avoid accidental black flags.

        Lime Rock Park

        – The first pit stall has been moved back one to make it easier to exit the pits past the armco wall.

        Oran Park Raceway

        – Added a checkpoint so turns 7-10 can no longer be shortcut.

        – North B pit lane speed reduced to 20mph to make it so that
        driving through the pit lane takes more time than staying out on track.

        Sebring International Raceway

        – New track surface shaders have been added.

        Virginia International Raceway

        – The last 10 pit stalls have been moved away from the pit wall to make pitting easier.

    Finally, iRacing delivering some more internationally recognized, proper F1 tracks. Beautifully reproduced. I love the little details in the vehicle dynamics like the inside front off the ground at 0:52, the inside-front wheel lockups at 1:08 and 1:13, the suspension movement at 1:24, and the new transmission sound worbles at 1:40.

    If iRacing could just fix their cold tire performance bust (cold tires are faster!) and add some dynamics to their environment (temperature, clouds, track), then this would be sim bliss. Problem is, seems like they are a long way from addressing these issues.

    Anyway, with the competition structure and pick-up racing, I don’t mind paying a bit of money for this!

    • Anonymous

      While it’s still in ‘soon’ territory, I’m very glad they’ve acknowledged that track dynamics are important and that they’re working on them. I remember a few years ago they seemed to think that if the track ever changed between sessions, everything would be ‘unfair’, so it’s a welcome about face.

  • Derek Speare

    Wow! This track is bill – I just took some laps around it, and though I know I’ll never get to do it in real life, this is the next best thing. Oh – and it’s maddening! The Brazilians will be stomping everyone else here is my prediction 🙂

  • terrible1fi

    can you adjust the steering ratio in the setup yet? This car is way too twitchy

    • Anonymous

      No. You can’t do it in the real car, so no way to do it on iR!

      • StarFoXySxv550

        Not even via the infamous “Monaco steering rack” most teams use?

      • Anonymous

        Don’t have the track, so they don’t have the higher ratio 😉

        Similarly, the longest gearing is the same Williams had at Monaco, nothing longer if you want to run it at Dega or something. Same with the ACO sports cars, they don’t have the Le Mans downforce package since we don’t have Le Mans.

        You can change your wheel calibration, though, to end up with a different ratio.
