[@reggiefromgamestop4985]

the reason you are not going fast is because with electric engines they do not provide enough rpms to switch gears, the game switches gears based on rpm, if you use combustion engines you will be able tu make use of all your gears and reach higher speeds. also electric engines do not necessarily improve acceleration they just deliver all power at once, with combustion engines it takes more rpms for more torque/power

[@DickShooter]

Exactly, the motors run out of power at high rpm. I'm seeing lots of people ditching the gas motors and running into this exact issue and can't figure out why it's happening.

[@pleck7059]

from what i have seen what you said is incorrect from what i know if it doesn't switch gears it means the engine wouldn't be able to accelerate if the gear increases or it would make the car slower if it switched gears

[@DickShooter]

@@pleck7059 electric engines don't have power at higher rpms. What he said is correct.

[@samuelloomis9714]

I found that it switches based on torque alone. If it can theoretically apply more torque in its current gear, dispite about maxing the rpm, it won't shift.

[@tanputt]

It's shown on the UI how they work you need a certain ratio of rpm to torque for it to switch gears.

[@maunewty]

2:23 So displacement, velocity, and acceleration are all things a part of calculus. (Theres also jerk, snap, crackle, and pop. It keeps going after that. Sorry its been years since I've done any sort of calc) Basically displacement tells you how far you are away from the origin point. Velocity describes how fast the you are going from displacement over time. (Speed is the absolute value of velocity, as velocity can be negative or positive) Acceleration describes the change in speed over time. Acceleration is the change of distance per second per second. ∆x/∆t² (or dx/dt²) Acceleration is a double derivation of displacement. Take a parabolic function. This could be a displacement. If you derive it once, you get a slanted line. That's your velocity. Derive it again and you get a flat line. This is the acceleration. Physics has the idea of throwing a ball. It follows a parabola. Its this principle. Small caviots in the relationship of origin points but that is the general idea

[@BoxPatata]

to simplify: displacement (dx) is the change of distance from the origin/starting point measured in meters, velocity (V) is the change in displacement according to the change in time (dt), and acceleration (a) is the change in velocity as time goes on. therefore, velocity is calculated as: dx/dt or meters per second, and acceleration is calculated as [dx/dt]/dt or meters per second per second which can be simplified to dx/dt^2 or meters per second squared due to the fact that division is the same as the multiplication of the reciprocal value. If you want to get a more in-depth description, I found Lumen learning to be very helpful when learning this for AP physics a while ago (I believe the unit is "3.6 Finding Velocity and Displacement from Acceleration"). Hope this helped :3

[@thesunnynationg]

@@BoxPatata very simple thx 😅😅😅

[@Jose-Sousa]

Sorry for the block of text below, just trying to help... Just some pointers: m/s² is the SI unit for acceleration, it can be decomposed into (m/s) / s, or in other words, (change of) speed in m/s over time in seconds. In blunt terms, if your car is traveling at 10m/s with a 1 m/s² acceleration it will be traveling at 11m/s in the next second. Since the acceleration is not constant for all the speeds, the game might be doing an average. Some issues with the OZTRON - 9 speed Trans shown at 2:30: It doesn't matter (at least for the game) to exchange torque/speed in the middle of the transmission (there is no free lunch, if you gain torque you lose speed and vice-versa), the ratios of each gear set are multiplied to obtain the final ratio of the gears used, if you put the big gear and then the small one and then the small one followed by the big gear, you are effectively just doing a 1:1 ratio, where one revolution of the input is one revolution of the output. For this reason if you have either neutral (1:1 ratio) or cancelling ratios between the gearboxes you are just wasting space and weight. Although, like you said, you can indeed change the gearboxes connecting gears to change the final drive of the transmission. The change you've done at around 8:49 made the transmission exactly the same as it were at 2:30! The chart scales the axis automatically so pay close attention to them when comparing stuff - at 36:11 the wheel torque the 4th gear changes into 663Nm and that is not enough to accelerate past 150mph with that car. The changes shown at 38:47 mean that the car will barely move as the provided torque to the wheel is really low, it isn't more 'smooth', if you normalize the chart without comparing with the previous they are exactly the same, just stretched and shrink according to the torque/speed of the drive ratio... In your specific gearbox, I did the math (the game considers the small gear to be 8 teeth, the medium 10 teeth and the large 16 teeth, even though that doesn't match the graphics) and out of the 27 possible gear combinations (3x3x3) you only have 10 unique ratios: 1, 1.25, 1.5625, 1.953, 2.3, 2.875, 3.594, 5.29, 6.661 and 12.167. The last one with 12.167 is probably too much for most if not all of the possible input power for the transmission, the required torque is too much. Usually, for something usable, if you divide the biggest ratio by the smallest you want something around 2.5~3 depending of the engine torque profile and number of gears, if going for top speed something around 5 is probably the maximum (assuming you start from a reasonable minimum ratio). You want the torque of the final gear to be just enough to propel the car forward - in electrics is easier since the torque is almost constant, in gas engines you have to account for the torque curve... I have designed 2 very similar transmissions, one with 6 and one with 8 gears, I don't recall the specifics, but they have 2 stages of gearboxes, one is a very simple one with just the medium gear and the small gear swapping ratios (the 8 geared one has an extra 1:1) and the other gearbox is very similar to the ones you shown but I think I put a 1:1 before the planetary gear and 2 gears swaps after the planetary to smooth out the jump of the planetary ratio. I designed these transmissions around the biggest gas engine of the game (50:46). I don't like to mismatch the engines in the game, it messes up the gear changes (as you also experienced at 20:29 - but might have been due to a loose engine - I never got hundreds of gears) as the torque curve gets 'steps' as the electrics run out of power making the driving inconsistent, adds complexity and you are chugging along with that dead weight when driving at high speed, if the initial gas torque is insufficient, make a first gear with a lower ratio, make the gear ratios closer and/or lower the overall final ratio of the transmission. My cars are about half the size of yours and the engines are near the car 'floor', having so much weight so high up will not help with the stability and drive-ability of the car. Also, there are aerodynamics modeled in the game, a larger car will have worse aero... 49:27 "How do we get to the to of that rock?" - I made an helicopter :D Hope it helps .... have fun!

[@yertzar775]

Nice breakdown. Also noticed it but didn't bother mentioning everything xD Honestly, props to u

[@CatSovietski]

I'm not smart enough to read that

[@0xDigby]

thanks for the detailed breakdown!

[@trebormcfarland8708]

When adding in your static aero it's important to balance it with the air resistance stat as the aero components can affect the air resistance depending on BOTH where and HOW they're placed, sometimes you can flip a wing upside down for better wind resistance, filling in large gaps in the "frame" also helps

[@Hlebuw3k]

I noticed that wind resistance and weight play a big role, whenever I try to build a big car with a lot of power, it ends up really slow, but a small one with just 2 electric engines and a good gearbox can go way faster

[@ajaxsakaraplayz4070]

It's always best to balance between the two but there are preferences haha

[@mathieularocque1953]

The easy way to line up the electric motor would be to have them face each other with an axel of length 5, 1 inside each pair of engine, 1 spacer on each side and 1 gear in the middle to connect them all... Also normally you make the transmission after having decided the engine / motor you want to use, it make it easier to adjust the power curve for the purpose of the car... If you want a big top speed do a 1 speed transmission with like 10 planetary gears in line going to the back axel, for a strait line you will go fast just not accelerate The loading speed is impacted by the amount of transmission change you have, the game struggles to determine the correct order when you go above 6 making the loading time longer

[@spacewalk3046]

20:10 The reason it creates so many gears is because if you use multiple engine types and a transmission with switching gears, the game has problems calculating gears. So it can create a lot of phantom gears. In future updates this will probably get fixed.

Aero is pretty important for top speed, it's def possible to break the sound barrier though. Highest speed I've hit so far is over 800 mph (1300+ kph)

[@martinak4532]

I would recommend using the short 2 unit long wooden connector in order to connect all of your engines together as the game always calculated the axles as a hinge point which could also cause some issues with power delivery or the weird torque graphs you had In my experience, even just a 200hp car can flex and handle terribly because of this effect the axles have when used on transmission/engine mounting Use the 2-by wooden connector and connect the engines between each other and it should be fine All the parts connected by an actual connector the game will calculate as a single object decreasing lag and similar issues (as I have mentioned) Besides that, great stuff!

[@karyjas1]

Ive yet to see someone do it, but ive done it, and i wish to see how would others do it. Planes. You can create flying vehicles in this game. The secret is to use two engines and have two symmetrical power trains. Gearing doesnt matter for direction, only the engines do.

[@Simon-tr9hv]

You cant, there are no thrusters in game, only engines that need friction of the wheel to drive with torque, simple as that

7:50 You can click undo at the bottom right to stop wasting funds like that! lol 8:57 Of course it's the exact same, you basically went form +1-1 to -1+1. 11:12 At a glance, you currently have the 3 sections on 3 different height level. You could have the 1st and 3rd sections on the same level to make it more compact. 16:12 My 1st thought to help with acceleration would've been to incorporate a planet gear in your driveshaft just to lower your ridiculous top speed. 18:55 Sometimes the game seems get stuck while analyzing cars, just swap back and forth to another car to make it refresh. Usually fixes it. 37:04 Again I'd be curious to see what a backward planet gear on the drive shaft would do with this setup.

[@Gabriel_O.]

Oh yeah also, a tip for getting insane funds super quick: Go to any 'A to B' race and right after 'Go' press your reset key. There's a glitch where it resets you to the finish and you can get like a 0.050 second time so it works if you just keep clicking retry to get funds extra quick. Use before patched.

[@JoMaABC]

15:47 The torque curve graph happily swaps between km/h and mph on the same axis...

[@hermantcherdakli2053]

The burnouts are because of the weight distribution - your rear wheels don't have enough grip and break traction on launch. It's pretty tricky to fix because just slapping a wing above them won't provide downforce at low speeds (when you actually need it), you have to either move the center of mass to the rear or provide an active downforce system with propellers.

[@ralphiemelphie]

You can also manually switch gears, there is an option in the menu.

[@Gabriel_O.]

@@i_Max_i haha honestly, I would never have the patience or braincells to sit for like an hour trying to perfect a transmission, but I have gotten a lot better.

Most times it ends in me abandoning the project tho 😅😅

[@i_Max_i]

@@Gabriel_O. I trying do by myself as much as I can, but sometimes tutorials is necessary. Also my 6-speed transmisson actually 3speed with 2speed before it) But it works good :D

[@struanroberts]

I believe it loads faster when you have already loaded the graphs in the build part. Also I was able to complete the long jumps much easier by using upside down aero which acted as wings. This was also useful for getting stubborn chests that are in hard to reach places. Great gearbox, I attempted a 6 speed today and it ended up being slower than my current 3 speed so think I need to try again with a different approach.

[@i_Max_i]

Mine 6-speed is just 3speed with another 2speed before it, and it works good, but I use only combustion engine, 4x 1000 with turbo. And with this I have 221hp and max (tested) speed is 560km/h (350mph). But also I use lowering before transmission, 8:24 (small:medium gear)

[@1nicube]

4:48 at the beginning... you dont need to go from small to big and big to small. It does nothing. Just use the medium gear. If the car have problem to shift, go in manual mode and shift yourself.

Acceleration is metres per second, per second, as in the gain of speed in metres per second over time :)

[@Grzelopak]

basic physics. ppl are accustomed to acceleration described as: amount of seconds to specified speed, but that is highly wrong in science terms.

[@drftr58]

It would be nice if you could input logic for the gearshifts, I've made transmissions that technically could have x amount of gears while the game auto selects and uses less thus making the gear changes rough.

[@christiangray7826]

I’m sure that’s coming. I can’t wait.

[@elderith3244]

m = meater, s = Seconts, and yes it is squared, but it is divided not times. it is a stantered unit of measuring the change of volcity over time.

[@pindamonhangaba72]

Man you need aerodynamica not downforce for speed Put them on theyr side man make it pointy

[@wallacesantos0]

m/s^2 is the SI for acceleration. 7 m/s^2 means for each second the speed will increase in 7 m/s (or 25.2 km/h). But there is probably something buggy with the game at the moment missmatching mph, Km/h and m/s.

[@isaacpry6363]

Also make sure on the electric only test that is can shift through all the gears

[@pothoc1]

Acceleration is measured in meters per second per second, generic speed is measured as meters per second. If you just think of acceleration as squared and not spelled out it makes a whole lot more sense mentally

[@TheRealHypervizor]

I have multiple cars that do 400+ mph… yes 400mph.. I have a 6 speed and an 8 speed. You have to use ice, electric motors are only good to use to eliminate the ramp up time. Add the motors inline with the gearbox and/or directly on the final drive. And more ice = more powah. My 400mph beast uses 16 of the big motors and 2 of the red electric motors. I’m on the speed trap leaderboard btw. Somewhere on the top 600 if you doubt. It’s really competitive in there, not sure how to make the car faster without redesigning something ridiculously long

[@christiangray7826]

Where can I see cars that fast? I’m struggling to break ~300 kph, mostly bc of inefficient transmission. I want to see a bunch of transmissions so I can start making my own versions and better cars but can’t find many. I can easily make cars that go 300 kph with good-great acceleration and ~60-80 air resistance (PRE spoilers). I’m using 300 hp, do I need more hp? Is that the problem?

[@TheRealHypervizor]

@@christiangray7826 hp helps, it’s a balance. By best car is geared for 445mph, has just over 1000hp, makes around 10,000nm of torque in first gear,and caps out at 412mph because of weight and air resistance. Your car could be geared for more but not have legs. You should only be using rwd for speed builds, cars don’t seem to benefit much from multiple electric motors beyond 2 of the red ones, I have yet to figure out diminishing returns on engines, but a planetary gear on your output seems to be beneficial regardless of how many shifts your car makes

[@Dusto9]

I've been doing max speed attempts the past few days and my current build got 2248 kph through the speed trap on the test map, and there's enough power and gear ratio left to reach at least 2600 kph. But steering becomes a limiting factor as at those speeds the gap between the buildings and the speed trap is like repeatedly threading a needle at mach 2. Any steering input to correct the trajectory halts acceleration for a moment and affects your trajectory literally on the opposite side of the map so you need to be thinking 20 seconds ahead in terms of steering input. Some tips: air resistance is a major factor so make your vehicle as narrow and low as you can. Length is free real estate. And pay close attention to gear ratio's and torque curves so you reach your target speed just before the torque drops off. Wheel size (radius) is also an important factor as that has a major impact on your final gear ratio; bigger is not always better depending on gear ratios.
