Oval bo deležen kar nekaj izboljšav:

The 2018 Season 1 build brings with it another physics overhaul to the asphalt oval series of the iRacing Service. In March, we saw sweeping changes across both the Class A and Class B NASCAR iRacing Series vehicles in an effort to bring the two cars closer to their real world counterparts and the Season 1 build in December will take these changes even further, with many of the changes being adapted to the NASCAR iRacing Class C Trucks as well as the NASCAR National Series car. 

One of the first things you'll notice when getting behind the wheel of these cars is a dramatic change in aerodynamic performance. Each of the cars updated in the Season 1 build have had a full rebuild of the aerodynamic map, with each car getting its own unique update: 

-Monster Energy NASCAR Cup Cars: The Gen 6 cars used in the NASCAR iRacing Series and NASCAR iRacing Class A Series have had a full aero-map rebuild to bring them up to the 2018 regulations. A reduction in overall downforce and sideforce will place more control in the drivers hands and reduce dependence on aerodynamics relative to previous builds. 

-NASCAR Xfinity Cars: An aero-map rebuild of the Xfinity Class B cars brings downforce levels down to the numbers expected from the 2018 specifications, as well as a mild reduction in overall sideforce acting on the car. 

-NASCAR Trucks: The Trucks have had the most dramatic aerodynamic change of all four NASCAR vehicles. In previous builds the Truck has had too much rear downforce which has required chassis setups to be mechanically very loose. This has caused rear tires to overheat on large tracks where aerodynamics are key, usually resulting in a spin. For the 2018 Season 1 build, the Truck has had an increase in front downforce to correct this issue. Not only has this corrected the issue with overheated tires, but testers have said this makes the Trucks drive even better than before! 

-NASCAR National Series Car: Similar to the Trucks, the National car sees a slight increase in front downforce to correct aerodynamically-induced understeer issues seen in previous builds. 

The updates were not limited to just aerodynamics! In fact, a lot of changes were made to the chassis themselves to bring them up to spec with what you see on TV on any given Sunday. While the aerodynamic updates were tailored to the specific car, these chassis updates were made across the board: 

-Front Suspension Geometry: The front suspension geometry and kinematics were updated to improve platform / roll / ride height control. Drivers will see issues that were common at short tracks like mid-corner balance shifts, late corner spins, and the high splitter heights have now been erased completely. 

-Sway Bar Update: The code for the front sway bar has been updated to more accurately produce the roll stiffness values that the various sway bar arrangements should produce. Further, sway bar preload limits have been narrowed even further to bring them in line with NASCAR's inspection process. 

-Front Shock Rebound: For the Trucks and Xfinity cars, maximum rebound in the front shocks has been increased significantly. The Cup cars have had a mild increase in rebound. Setup builders will notice that a full-rebound shock can now be used to "tie down" the front end. This update has also opened up the possibility for various setup types without sacrificing speed. 

-Track Bar Rake: When the car is loaded into the world and the car settles, the track bar heights we set in the garage are not the values registered in the sim. With the 4" rake limit imposed in the March 2017 build, this produced an effect where the right side of the track bar could never be higher than the left side. To correct this, the range has been opened up to allow for proper track bar configurations. No need to worry though, as the issue with high rake angle and rear toe has been eliminated with a tech inspection check on the rear toe values. 

Finally, we move to the most dramatic change drivers will feel in the cars: Tires. Great care was taken when updating the tires to not only slow the cars down, but put a much stronger emphasis on tire management. All told, cars should be 1-3 seconds slower at 1.5-mile tracks, as well as seeing a much steeper initial falloff for over-stressing tires. Lap times, in general, should be right around what we see in the real world, and how you break-in a set of tires will determine how long they last through a run. Drivers will need to learn to brake properly for a given track as well as break the old habit of getting to the throttle too early. Should you go all out for the first five laps and try to get away from the pack or should you work the tires up slowly? The choice is up to you, and that decision could very well be what wins you a race (or loses it). 

In addition to these major changes, minor alterations to the physics have brought the cars closer to their real world counterparts than ever before. For each change made to the cars, none were accepted unless they produced the correct values. Downforce levels, tire loads, lateral forces, and even details such as how long drivers have to wait on the throttle were meticulously changed until the requirements to drive these cars at their limit matched what the real drivers have to do to drive their cars at the limit. Testers have all agreed that this is the most fun these cars have ever been to race, and the data shows that they're the most realistic they've ever been on track. We're thrilled to finally get these updates out to the public, and look forward to racing with you in the 2018 NASCAR iRacing Season.

A si ja normalen, tolk teksta še v šoli za domače branja nismo imel, zato sem sam preletel in se mi zdi, da tole ne velja za road. 

[markop 702]

Zgleda, da zal ne. Ta build se mi zdi precej oval orientiran.

[edgeslo 1 162]

Pha ?!?! WTF ? Spet smo zvisel ? Rage quit !

Mah načeloma tudi če ne bo drastičnih sprememb bo ok

Jaz sem po dolgem času spet na Porsche in se sprašujem zakaj sem sploh kdaj nehal ta avto vozit

-NASCAR Xfinity Cars: 

Kaj bo pomenilo tole: a mild reduction in overall sideforce acting on the car

Ps: a pit animation pa še ne bo?

[vajtos 227]

Pit animations available on 5th of december  

[markop 702]

Nov GTE avto za 2018 confirmed. 

@edgeslo: Jaz se ze dve sezone locujem in kar ne gre in ne gre...

[silicijeva dolina 1 254]

Kateri pa?

[mancSLO 1 945]

Kaj menite, da bo tole pomenilo v praksi:

NASCAR Xfinity Cars: An aero-map rebuild of the Xfinity Class B cars brings downforce levels down to the numbers expected from the 2018 specifications, as well as a mild reduction in overall sideforce acting on the car.

Ne vem kaj v praksi pomeni da bodo downforce pripeljali bližje sezoni 2018. To zadnje pa predvidevam da govorijo o sili ki na avto deluje ko zavijaš.

Malo manj moči, pa nekoliko prej v steni se mi zdi...

Slabe novice:

Any chance someone on staff could let us know if the spotter in the background is either just a part of the video or something we'll see in game either this build or soon after? 

Thanks

That audio was just used for the video.

[vajtos 227]

Js uporabljam crew chief-a povsod tk da  

[edgeslo 1 162]

Tud jaz sem na crewchief tako da me kaj dosti spotter ne tangira ... 

Kje pa sploh teče debata na iR o spotterju ?
