Designing an Electric Hypercar | Mondays with Mate 05

[@essentials1016]

Please make a Video with the engineers of the Powertrain and ask them what difficulties they had to overcome

[@drummerdoingstuff5020]

My favorites along with Christ King (Play on the name Christian Koenigsegg😂) of car makers! Humble genius game changers!!

[@Cloxxki]

Guess where Mate used to intern before he outgrew it :-)

[@MaN2Mega]

Favourite episode so far, the C2 is probably a more functional design from a engineering perspective but the C1 is my favourite, it looks spectacular, the form is so aesthetically appealing it's ridiculous!

Finnaly... Waiting for the video.. MATE could you tell me what is the greatest difference between C2 and Tesla roadster 2....and how you see the price difference... As tesla costs 200k and your is almost 10x times... In which way the c2 is better?...and how do you see this as impact of sales of your car.. Thank you... I am your fan from slovenia 💪🔥

[@derbigpr500]

Tesla's are designed to be as cheap to produce is mass numbers as possible. That's the source of all differences. :P

[@Cloxxki]

Not Mate, but in case he doesn't get to this one, my take: There are just a few similarities. 4 wheels, battery, impractical for moving around a stack of suitcases. Oh, and both get off the line really quick and reach 400 kph. The is an extension from it's mass produced cars. Many parts and architecture will be shared with those. The Rimac is a showcase for Rimac's expertise developing things in-house for others. Nevel level monocoq design, bespoke user interface, all for just 150 examples to be built. The Tesla will be made in the thousands with lower attention to detail. The numbers make it more affordble to the end user but the production line will likely cost more than Rimac's. For now, we don't even know where the Tesla will be built. We don't even know whether the cells for the Tesla are actually in mass production yet. The 200 kWh figure implies they need to do something very, very special. That cost hundreds of millions to acquire/develop, but will benefit all their other car models. Rimac seems to be using slighly more available cells to come to a very impressive 120 kWh in a car said to be under 2,000 kgs. A Porsche Taycan turbo S with around 93 kWh and under 600 kW (less than half Rimac's) weighs in at 2,300 kgs. Oh, and that one costs almost as much as the teased Tesla Roadster. Developed together with Rimac, probably, as Porsche twice bought share in Rimac. I suspect to skip the line. Rimac were fully booked years ago, no time to take on more projects. They could not hire and train people quickly enough to grow that quickly. Demand from unnamed car brands was tremendous. Porsche, despite really knowing their hybrids, needed help. Took Rimac's two-speed gearbox idea, it seems. Something Tesla tried but could not get to work and thus went 1-speed after all. Rimac is a tech company to the automotive industry like Sherlock Holmes is a consulting detective to the police force. The fact that Koenigsegg, the more renowned self-fabricator in the industry, chose to just have Rimac deal with the battery, speaks absolute volumes. Sherlocks like a good challenge. Rimac started building a world shocking hypercar from "zero". Even the original Tesla Roadster was an adoption of an existing Lotus car, known to handle really well. Compare what they did for 8 examples of the Concept One versus Tesla making many original Roadsters. Inside and outside. There are more expensive cars on sale that just have an AMG engine in the back, rear wheel drive only. Rimac works miracles. I actually tried to hire Rimac once for a company of mine. They were too busy :-)

[@JRP3]

@@derbigpr500 That's obviously not true, especially in regards to the Roadster. However Tesla does have the advantage of being able to leverage their mass production of cells and battery packs as well as motors, inverters, and all associated electronics to help lower their costs.

[@marsrover790]

Competing with tesla is quite a challenge. You have to compete with them in specs, range and price. As tesla technology gets better, it gets cheaper.

[@freddieb1903]

@@marsrover790 hopefully it doesn't become like Nissan where some of the parts of the GT-R may come from cars that are nowhere near that price bracket

[@adityashenoy1567]

The livery spells out RIMAC in order of 12345!

[@TheRahullamba]

Hi Mate. Your videos are really thought provoking. My question in how do you embrace changes that happen with your packaging/structurally frequently. Also how do you choose between conflicting solutions to engineering challenges. Is there some kind of priority list that helps you to choose in between multiple solutions ?

[@Stuntsmaster095]

Can we have a similar episode where we hear from some Engineers (Mechanical, electrical, software etc.) about their work at Rimac Automobili?

[@GiuTan3002]

Hey Mate, which type of a suspension do you use on C2? I think that I saw in one video that you use McPherson type of suspension, but I’m not 100% sure... Also what were biggest challenges with monocoque chassis?

[@sny9902]

Hello Mate'! I think the vehicle dynamics part of the development and a bit of insight into the methodology behind building a hypercar and the challenges it brings would be interesting to watch. You could even add the autonomous driving simulations and tech you are developing into the video. Whatever it is, we will be waiting for it next monday!

[@antonnpn9063]

Copper or aluminium for HV cables? Which type of semiconductor is being used for the power inverter?

[@MADMAX7330]

For the next episode, can you please go over the battery management system and thermal management system?

[@file211]

Hi Mate! Greetings from sunny Split! :) I'm wondering how are you managing to cool your battery cells terminals (construction-wise), and which media are you using for the purpose (if there are no secrets there)? As the next guest I'd like to see the CFD chief and hear him talk both about aerodynamics as well as thermal CFD. Pozdrav! :D

[@Cloxxki]

I understand they cool the cells with something like aluminum or silver on the ends of the cylindricals, plus the cells are fully submerged in cooling liquid. Might be wrong. Rimac will be relatively tight-lipped about details as their whole business is selling their expertise to large car manufacturers who have a huge knowledge and skill hiatus in this field. From one man, mate, they have built a company of world renowned experts. They ran out of Croatians with anything like the required skills and started hiring globally.

[@gery4870]

QUESTION: What is the battery Voltage in the C_Two ? Higher than Concept One ? Thanks !

[@shannons1886]

So happy to see this company! Biggest fan in 🇺🇸!

[@lazyman1011]

Last time i watched a Rimac Video was when you where afraid about the first customer/investor. But I felt you're doing everything right and now everything is rolling, and you are able to stand next beside a Koenigsegg on a fair and make it hard to deside which one to buy.

[@ivanturkalj8867]

I am so happy 😃

[@dirrrrr82]

Mondays with Mate: Lead Engineer interview please

[@MattsPaddock]

Hey Mate! I have a question for you! Are you already looking into solid-state batteries and what kind of possibilities those bring to the table, or maybe even Ultra Capacitors like ones from Skeleton Technologies? Do you have any kind of rapport with some of the leading manufactures in that field? Thanks!

[@d1a]

watch the pervious episode, he talks about that

[@MattsPaddock]

@@d1a Awesome, will get right on it, thanks!😊

[@theonlymudgel]

Love these videos Mate. when are we going to see Mischa Charoudin on the channel?

[@freddieb1903]

Can you show the engineering and design of your electric motors for both the concept_one and the concept_two please. BTW = Mate and the entirety of the whole Rimac team if you're reading this, I want to just let you know you are doing really well for a little electric car company in Croatia so please continue to push the boundaries of super/hypercar performance

[@Cloxxki]

They are doing exceedingly well for ANY tech company, world wide. They so happen to be dominating the R&D, consultancy and series manufacting in BEV tech. Tesla has the sales number of cars. But if Porsche needs help, they call Rimac. Rimac says "we're busy". Porsche asks "what will it take?". Rimac "we might consider a small stock emission. It will be expensive". Porsche: shut up and take my money". VW: now we need help to make an ID.R. Yesterday.

[@freddieb1903]

I agree with this statement and if they continue with working with Porsche on the batteries, motors etc it can really benefit both companies a huge bunch.

[@Lasharella]

I’m so enjoying your guys videos I love this car even though I will probably never be able to buy it I am still just amazed and very excited for its development and success just very inspiring to see these two humble guys started this and are so successful much respect and love, god bless you both! ❤️

[@jimi7170]

I'm currently studying electrical engineering at Uni, someday I want to work for you guys, I use altium for PCB design, can you guys tell us a bit more of the software used to design systems specifically electrical systems.

[@robertperkat9508]

What type of electrical conductors are you using to transfer so much energy to electric motors and for charging and how do you dissipate that heat? Which mode of charging are you using, and can you charge your cars on standard charging stations ?

[@imranlivesit]

Mate, Thanks for taking the time and making very informative videos into your world of high-performance electric cars. First question: "How do you design a cooling system for a car with this level of performance like C2, what are the factors that you would consider before doing it?" [Keeping battery degradation in mind] (Can you make a video on the cooling system?) Second question: "How do you see the Rimac's future would look like in this dramatically changing Automotive industry?"

[@axemanracing6222]

You guys remind me of the garage computer geeks of the late 70s. You're not creating something new but something very special.

[@barleytamper671]

Hey Mate why do you have a wing door and not the falcon door or any other? Thank you for the videos.

[@MotionBlurDevelopment]

Love the series! Would really like to see how the cars are tested and how the data is used to improve the suspension behaviour and torque vectoring input. Thanks!

[@michaelevans1499]

Is there enough head room to fit a helmet on? If the driver is over 6 foot tall. Can the seat be made thinner or lower to make more head room ?

[@999vlada]

Da li planirate proizvodnju automobila koji bi bili jeftiniji i pristupacniji siroj populaciji? Concept One je neverovatan auto ali veoma mali broj ljudi moze da ga kupi.

[@domcroatian4044]

Mate što misliš o gorivim ćelijama kao ekstenziji dometa? Glavni razlog je marketinški. Privuklo bi masu interesa. To vrijedi beskonačno. Čak i ako tehnološki stvar nije 100% spremna. Može biti opcionalna oprema. Metan ili vodik i C02 ostaje na nuli. 20kW ćelija + metan za 500km bi mogla biti ispod 100kg. Navodno je razvijena tehnologija niskotemperaturnih ćelija za metan...

[@murb2586]

hey mate, god bless and congratulations with your company and your vehicles, definitely hope to see more. as well i believe your rimac one really jabbed the established performance brands to up their game. i always sensed they were holding onto their much more complicated yet profitable set-ups and were consciously retarding the progress of electrical systems. one question ive asked others but had never found or received an answer to. why are there no concentric dual motors where the outer motor uses the casing of the inner motor as its rotor, effectively multiplying rpms of the two without need for a transmission. in this way, you can uses low rpm high torque motors and still have the available rpms for top end. thanks and best of luck

[@serekkiri]

Next time maybe some engineers that are working on software?

[@VedranBaric]

What were the main challenges regarding the suspension and torque vectoring system integration?

[@HaraldBrevig]

Having ane elecrtic car myself i would just ask you to neard out more!!!! dont be afraid to make loong videos about how batteries in cars work. But my question is how are you planing to handel the cold? Living in norway i everthing gets harder when its cold. So how do you plan to heat up the battery?

[@vaibhavsharma7136]

What do you think about GaN (Gallium nitride)...? @RiamacAutomobili It's said that it has 30% more efficiency than traditional Panasonic cells that you were talking about in the last episode...

[@hardmiskomisko]

Mate I have one question for you. When you had the idea about a company. When you visualized it like you visualize Rimac that we know today. Did you openly share that idea and tried to find people that would help you to build a company or did you planned all in your head, started company and then hire those initial 5-10 employees? Otherwise I'm a fan of your work and wish you all the future on this planet! :D Lep pozdrav iz Slovenije.

[@anjaa13]

If the tie is your thing... why don’t you have one with Rimac design? 😁 How do you test cars and batteries? Was it emotionally hard to crash test your cars?

[@freddieb1903]

What they probably do is create a replica which will be cheaper

[@askvic611]

01:00 noticed your infotainement-graphics slightly lagging in the car itself, have you fixed it or do you need any help, asking for a friend ?! 😋

[@pawejarosz8046]

How do you test your designs, what tools are used what kind of skills are required in order to test each component alone and as a part of the whole car ? Are you testing your models on every level of production (from scratch to real riding model of the car) ?

[@Cloxxki]

There is a video where they showed converted older motor versions built into a dyno to test new ones. So clever. And saved them millions they didn't have in something existing for the purpose. Using electric motors as a dyno for same makes the net needed energy actually quite low.

[@pawejarosz8046]

@@Cloxxki Ok, It is one test of many others and I saw it to, however car is made of many other components which require testing as a whole. Different types of tests E.g. long distance car testing, different weather conditions : Day, Night, rain, snow, wind, temperatures below zero Celsius, temperatures above thirty Celsius, how car behave on the race track etc... I think most of the tests on the early stage are tested as a mathematical model objects in the software like Matlab in some specific simulated conditions, but it is only my guess ;)

[@markdavis2475]

Another great episode thanks! This content is priceless, information and knowledge from the "the horse's mouth"! Is it right to assume that if you have an air discharge duct at the rear of the car, it can be designed to use the venturi effect at the rear to actually suck the air through the duct, instead of the air being "forced" though from the inlet end?

[@dangcool3864]

Do you plan to or are you currently in the process of developing autonomous vehicle technologies? This might potentially be for future projects as the concept 2 is clearly focused on performance and driver engagement.

[@derbigpr500]

They said many times that autonomous driving is one of the key elements of the C2, loads of processing power, loads of cameras and sensors, etc.

[@ndeco2]

You are good. Dobri ste ! Samo rokajte! Sretno. :)

[@eGaming180]

When will the final version of c2 be shown to the public? Since it will probably be shown at some of the auto shows, and they are being cancelled because of the corona virus, is it possible that the premiere of c2 will be delayed?

[@Cloxxki]

I could imagine that if a trade show doesn't happen, they'll just start customer deliveries. With many hypercars it goes that way. It's kept nicely under wraps so the first customers really get something the world has barely seen online, let alone in person.

[@tusharbarde2510]

Rimac is about innovation in technology, is there a person or a team that is tasked with coming up with ideas for the car that don't exist currently? Having 4 motors working individually to improve performance feels like such an idea. I would really like to see an interview with this tech philosopher/ philosophers if there is one or several. Tech philosopher, maybe Rimac can be the first car company to have this title, "tech philosopher" if it doesn't exist? 😁
