Raceroom | Truck DLC Released

rr_trucks.jpg
Sector3 Studios, now officially known as KW Studios, has released this morning Trucks DLC for their simulation RaceRoom. It is available to purchase in their store for 3,98 euros.

Trucks are completely different animals when it comes to driving and simulation. Now Raceroom offers this experience building a "generic" truck and introduces us with some advice to enjoy this discipline.


Features of the RR Truck
  • 1100 HP
  • 5000nm @ 1250rpm
  • 12.4 liter 6 Cylinder engine
  • 5300 kg
  • 16-speed gearbox
  • Water cooled Brakes
Sascha Lenz, a real truck driver, has helped to develop this content and to recreate all the features that make this discipline so exciting. The trucks have a brake cooling system, two stages transmission system and a unique driving style, which varies substantially from a racing car.

There are 16 gears divided into two ratios of 8 gears each. Low Split for better acceleration and High Split for top speed. You have different accessibility options to make it work with an H shifter or sequential one.

Brake cooling system consists on a water tank limited to 200L that you must manage during the whole race. You can operate manually the system to gain an advantage over your rivals.

And remember, trucks have a speed limit of 160Kph at all tracks. An engine limiter will do the job to stay safe as in the real life.

Let us know your thoughts on the R3E Truck DLC

Had a go, they roll over on kerbs? They sound like a bus when you're off throttle and tbh reiza do a much better job with trucks even back when they released their own dedicated truck games they felt better than this. Only thing it really has over that is the brake cooling.

I am here for this, and the dissapointment,

So I saw Sim race Bible review. Very cool.
I went and tried it myself.
The gears?! Is that in the rule set? I only ever see or hear the trucks in the ETRC shift in the top3 max gears, why force this in Sim? I ask this because the rear end is not locked like in the ETRC, I like the brake heat management. I don't drive these in real life but is it more accurate than the AC version? Or even than the (very different) Copa Truck driving.
It is fun , maybe I've been spoiled with AC and TruckRacing titles from other sources

They sure do seem to roll if you hit kerbs the right (wrong?) way. :roflmao: But they're fairly fun to drive. And much as I wouldn't want the speed limit, it is realistic to many truck racing series. And I really like that RaceRoom is willing to spend the effort on adding new systems in their sim to better simulate specific content - e.g. brake water cooling with trucks and MGUK systems for the new F1 cars.

If I ever buy content for RaceRoom, I'd buy these. Would want to support developers doing something unusual like this.

Having just tested the AMS1 Formula Truck and the RaceRoom truck back to back at Portimao, though, I'd choose the AMS1 trucks. Partially because there's no speed limit :p (only speed traps on FTruck circuits) but also cause they feel more "immediate" in my hands and feet.

These trucks really seems pure phantasy, because they don't have the locked differential that's mandatory according to the FIA regulations. Therefore they are far more agile than they should if both rear wheels have to spin at the same speed all the time. They have also passed my open-differential test "positive" means, if you accelerate them with one half on the grass, they go perfectly straight and not rotate to the grass-side, which they should if transferring torque to the wheel with more grip. The Fabcar with locked diff did as expected, so spins towards the grass-side.

Edit: Trucks are fixed. Tried the same spot than yesterday with more expected outcome.

I've even noticed this 'issue' in their video before trying them, since you have to drive cars with locked differential differently because of the turn-in understeer. You have to use the throttle-oversteer to rotate and so the slowest point of a corner (righ before you go on the throttle) is typically on early entry, not mid-corner.

In that case what's the side with more grip? grass or tarmac?

Sry but the Copa trucks are not really comparable to ETRC trucks in RR because the differences are huge and that starts let alone with the size. Brazil Copa trucks are way smaller ^^ Also they do not really look like road going trucks anymore at all whereas the ETRC ones still do.

And the full list of differences is pretty long if you compare the tech regulations of both series:

ETRC vs Brazil Copa Trucks Regulations - Google Drive

drive.google.com drive.google.com

As example the allowed front wheel camber for Copa trucks is -3,5° compared to 0,0°!! in ETRC...

And because of not being allowed to have negative camber the ETRC trucks do other things to gain some camber in corners :p

So yea of course they feel way differrent than trucks in AMS1/2 because they are way different. Comparing them or expecting to drive, handle the same does not make much sense. :)

Just a FYI so you don't get false positives/negatives in your test:

With a spool on throttle on your µ-split test the cars tendency to rotate would go towards grass side because of the grippy tarmac surface. (Fabcar assumption)

An open diff would head straight and light up the grass side wheel.

Behaviour of LSD depends on locking amount. Theoretically you can get actual traction when tuned right for that scenario (which doesn't mean, it's tuned right for regular track driving of course).

They are indeed very different vehicles. Both have an appeal on their own and tbh. it's IMO great that there is this variety to choose from in the sim world.

There's always one isn't there. :roflmao:

The following data is collected from the truck in game running at Zolder.

Here's a graph of the front wheel speed difference throughout a lap:
(Ignore that it says diff as I use the same worksheet for setting up 4wd cars in game)

Two pretty maps showing the same data split by on and off throttle:

Now here's the rear wheel speed difference throughout that same lap:

1669104389743.png


I'll just zoom in a bit in case that isn't clear enough:

Can you guess who couldn't try the trucks yesterday because R3E wasn't installed? This guy! :coffee:

So I watched a few videos by the more popular Youtubers and none of them took the 10minutes it takes to inform themselves about how to drive/shift those things and now I'm very disappointed in those guys :(

BTW, anybody remember Mercedes Benz Truck Racing from 22 years ago? ^^

It's now abandonware if you're interested:

You are right, but the Fabcar really went to the inside on this hillclimb track. Seems there is a strange grip-anomaly there. Anyway, only open diff goes straight.

And if you don't believe the devs, here is telemetry from a lap around slovakia-ring, the diff is 100% locked.

You can also really feel it in tight corners, where this thing just understeers like hell. On fast corners it is not so obvious, my guess would be that because of the weight, high CoG, and most of the weight in the front, the rear inside wheel is reeeealy unloaded and just easily scrubs the surface.

Also, when you look on onboard vids from ETRC, like Steffi Halm around Misano.

The behaviour looks pretty similar to what is in R3E - little to no shifting (just 7H-8H0, understeery, and pretty stable on throttle (so none of the on-throttle twitchiness that is present in other sims).

Also, I've seen these racing in person a few times, and from the outside their behaviour looked pretty similar to what is in R3E.

So because he doesn't like them his opinion is being classed as conspiracy? Clearly not allowed an opinion that's different from anyone else's on this forum. Enjoy wasting your time and money on "simulated" trucks from "real data" that roll over as soon as you touch a kerb :roflmao::roflmao:

Opinion is one thing, but re-read his opinion and how he presented it, and then come back to this.

I looked the one thing that really stands out to someone like me that has been to multiple British Truck racing meetings is him trying to say if they had locked diffs theyd understeer and theyd need to use the power to rotate the rear. Thats rubbish.

As big and heavy as them trucks are when they turn, them things turn without too much fuss. If they do understeer you cerrtainly never notice it in any onboards or trackside. Theyre some impressive pieces of engineering all be it the engine being slap bang in the middle of the chassis rather than further under the cab helps with centre of gravity and weight distribution.

Looking at ETRC onboards, I can very clearly see initial turn-in understeer, followed by the driver using throttle to assist the turning and then modulating it to avoid wheel spin on exit. In fact they look like they drive very much like the Copa Trucks in AMS2 do.

Not really.

Here you can se ETRC around the Le Mans Bugatti track (which TBH is about the worst track you can run a track at), with telemetry. Notice how quickly they are on full power. There is some modulation throughout the corner, but none of the throttle dancing that is required in AMS 2. I.e at 1:25, he is on full throttle mid way through the second part of the Dunlop Chicane.
Or 2:50, he is on full power throughout the whole whole turn, and it looks stable.


It's pretty much how you need to drive them in R3E. And as was mentioned previously Copa trucks are different specification, and smaller size. So the way they handle might be correct for Copa trucks, but is not correct for ETRC Trucks.
