The Rimac Nevera Just Shattered Pretty Much Every Acceleration Record
- aerodog 3y agoA Croatian company founded by a guy who's..35...
- WJW 3y agoWhat does the age or nationality of the founder have to do with it? Do cars go less fast in Croatia?
- tgv 3y agoThe obvious, I think: Croatia is small and doesn't have much of a car industry, nor of a history of tech development.
- fiksie 3y ago>doesn't have much of a car industry Rimac is focused on electric car part development like electro-hydraulic brake system. You don't have to have assembly lines for that. >no history of tech development Croatia has Rimac and Infobip, which puts them above average unicorn per capita in EU. Companies are succeeding in spite of leftover corruption from commie times.

- BerislavLopac 3y ago> nor of a history of tech development Oh, it has a very long history of tech development, including that one guy whose name was stolen for that other overvalued EV company.
- tgv 3y agoI haven't seen much of that history, and Tesla might have been born in current Croatia, but was ethnically a Serb, but most importantly, he did most of his work in the US. I think that's what makes that car company more remarkable: talented tech/entrepeneur doesn't go to the States.
- BerislavLopac 3y ago> most importantly, he did most of his work in the US That is correct, and I agree that it's most important -- his ethnicity is completely irrelevant (no more than Steve Jobs's Syrian one) and his place of birth just slightly more, as it defined where he went for education (Graz and Prague) and early work (Budapest and Paris, which led directly to his move to the US). > I haven't seen much of that history Which is fair, especially considering the fact that it wasn't a separate country for most of its history. But things like electric speedometer, military torpedo, rubber hot water bottle and a few others came from there.
- dna_polymerase 3y agoI'd argue the company would be less remarkable if it was founded by an 50 year old ex-BMW manager in Bavaria. Mate Rimac is an impressive man, have a look here: https://en.wikipedia.org/wiki/Mate_Rimac https://en.wikipedia.org/wiki/Mate_Rimac

- vrc 3y agoWho’s also now the CEO of Bugatti Rimac, a new JV between Porsche, Bugatti, and Rimac.
- metadata 3y agoI will just put this here: https://youtu.be/WAf1_zWThyE?t=526 https://youtu.be/WAf1_zWThyE?t=526
- yardie 3y agoWho started his company at 23 which is even more impressive. The founders of Tesla for, example, were well established in consumer electronics before starting the car company. And cars are the most complex consumer electronics on the market. So starting this endeavor in your early 20s is really impressive.
- tylerag 3y agoGordon Murray built his first car in his early twenties. Koenigsegg founded his company when he was in his early twenties.
- dig1 3y agoDon't be fooled by these headlines. His father is known for close ties with the ruling party and was/is under investigation for all sorts of laundering and land schemes. I would not be surprised if some of that money ended up as a seed for the company and car development.
- matwood 3y agoRimac has been making some insanely performing electric cars. Richard Hammond crashed a prototype on The Grand Tour. https://www.topgearbox.com/cars/entertainment/the-grand-tour/richard-hammonds-rimac-concept-one-crash-in-detail/ https://www.topgearbox.com/cars/entertainment/the-grand-tour...
- joelthelion 3y agoI wonder what its top speed is?
- doikor 3y ago412kph/258mph Or at least that is the fastest speed we have seen it go in videos. edit: Also the top speed according to https://www.rimac-automobili.com/nevera/ https://www.rimac-automobili.com/nevera/
- expertentipp 3y agoI stopped being excited about super cars at around 18. Give one to Ronaldo, one to some random sheikh and forget about it.
- detrites 3y agoMaybe they interest HN folks because they sit at the edge of humans technical ability? There are likely a good many similarly-distinct pieces of technology you are excited by, or you wouldn't be here.
- HPsquared 3y agoIt's just another form of art, or perhaps engineering as a sport.
- m463 3y agoI find it nice that fast or beautiful cars have been more accessible to regular people every year since the lamborghini countach or ferrari daytona.
- ourmandave 3y agoIt's very frustrating to see the 1/2 mile record time in seconds and then go looking for comparisons which are all in mph or kph instead of seconds. Yes, there's pace calculators, but that would require effort on my part.
- Sharlin 3y agoDifferent things, surely? Seconds to half mile is a measure of (average) acceleration; we’re starting from a standstill. To get the speed after x seconds you need to know the acceleration curve and integrate; knowing the average acceleration is not enough. Kph or mph are measures of (instantaneous or sustained or average) speed and do not tell anything about acceleration.
- TeMPOraL 3y agoAsk GPT-4 to write you a bookmarklet/userscript to convert those automatically. (I mean it. I'm still in awe of this even being possible. But it's great for one-off band-aids like this.)
- HPsquared 3y agoIt's not possible unless you make assumptions about the acceleration rate: does it accelerate a lot at the start, or is it sustained? It depends on mass, power (and how power output varies with speed), and drag (and how this varies with speed). Definitely not a simple unit conversion.
- voldacar 3y agoIf your velocity is over 400 kph and you just slam on the brakes and keep them on 100% until the car stops, does that not just totally destroy the brakes, maybe even melting them? (The kinetic energy of a 2300 kg object moving at 410 kph is over 50 gigawatt-hours) Edit: I made a typo in wolfram alpha :]
- doikor 3y agoThat is why they make the brakes out of fancy carbon ceramics. You can still burn them but not in a single 400kph to 0. They do kinda suck when driving slowly as they only really work well when hot but electric cars can just brake with the engines at those speeds to make up for it. Though they are used in combustion engine sports cars too so it is not that bad. Just need to warm them up like tires when driving hard on a race track. For sports cars carbon ceramic brakes also have the massive advantage that they do not fade with heat like traditional brakes.
- bitexploder 3y agoMost modern sports cars with proper brake fluid (higher boiling point) and some heat management have no problems with brake fade in steel discs. Many that track their GT3 / GT3 RS (Porsche 911) prefer steel discs due to the maintenance cost of carbon ceramic and properly designed steel discs perform just the same as carbon ceramics because the brake fade isn’t a big problem, even in a pretty extreme application like this. Not sure if the Rimac really needs anything otherwise as well. Plus, it has regen braking and a crazy cooling system to help there. Parents math was off about the amount of energy also. My car has carbon ceramic brakes (GT3). Two reasons: don’t need to be warmed up for full stopping power and way less brake dust. That is the only advantages in practice. On the track warming the brakes up is easy.
- smcameron 3y ago> over 50 gigawatt-hours That can't be right. 2300 kg * sqr(410000/3600) * 0.5 = 14893006.000 Joules 14893006J * 0.000277778 = 4136.9 watt hours Edit: out of curiousity, in order to have a kinetic energy of 50GWh, it would need a speed of 1424260 km/h (884994 mph)
- lucb1e 3y agoSpecs say nearly 500km range.... but at what speed, was what I'm wondering. How long can it do, say, 250km/h for? It's cool that it gets there so fast, but if then you need to charge after 3 minutes because the battery pack had to be small to get the acceleration so high, then there wouldn't be much of a point.
- sundvor 3y agoAny car regardless of propulsion will have its range slashed pushing that much air, so I don't quite see the point of the question? Battery pack is a very large one, at least by Model 3 standards. Details are in the article.
- tromp 3y ago> How long can it do, say, 250km/h for? Presumably well under an hour, with air resistance increasing quadratically. > because the battery pack had to be small Its 120kWh battery is quite large by industry standards, even exceeding that of the Lucid Air.
- doikor 3y agoUsually some standard like WLPT (or NEDC before it came around) is used. Though Rimac does mention on their site that proper WLPT testing has not been done yet so the "final" range will be updated later. https://en.wikipedia.org/wiki/Worldwide_Harmonised_Light_Vehicles_Test_Procedure https://en.wikipedia.org/wiki/Worldwide_Harmonised_Light_Veh... https://en.wikipedia.org/wiki/New_European_Driving_Cycle https://en.wikipedia.org/wiki/New_European_Driving_Cycle Also I highly doubt the battery can even discharge fast enough to fully run it out in 3 minutes.
- jackmott42 3y agoThere isn't anywhere you can go 250km/h for 3 minutes anyway.
- rad_gruchalski 3y agoI know of a couple of places but indeed, not many.
- mach5 3y agodangerously fast, this shouldn't be legal. if you were to build a drag racing car to those speeds you'd need a cage certified to 7.50s, something like this https://cdn.shopify.com/s/files/1/0362/8420/3141/products/25.5FoxbodycageKit_1800x1800.jpg?v=1651167660 https://cdn.shopify.com/s/files/1/0362/8420/3141/products/25...
- jackmott42 3y agoDo you have intimate knowledge of how strong the carbon fiber structure of the car is? Like, I agree we shouldn't have cars that can go over even 100mph on public roads, as that risks other people's lives, but all of them can already. If someone wants to risk their own life with an insufficiently caged car at a race track, that is their business, no need to make it illegal. Plus drag racing has recently changed the thresholds where cages are needed to be more in line with modern cars, which are stronger and can go 8 seconds without any drama, and have good brakes to stop from there.
- mcculley 3y ago> Like, I agree we shouldn't have cars that can go over even 100mph on public roads, as that risks other people's lives, but all of them can already. Do you mean in the U.S.? Everywhere? My understanding is that cars in Germany often exceed 100 MPH.
- zorrolovsky 3y agoFun factoid about the Rimac Nevera: it's a crappy name in Spanish (European flavour). Nevera means fridge and it's used in everyday language. It sounds really uninteresting. Now that we're a bit off topic... let's talk about Mitsubishi Pajero. Also used in everyday language in Spanish and it means 'wanker' (UK) or 'jerkoff' (USA). They had to change the name in some markets because it sounded really funny and/or awful https://en.wikipedia.org/wiki/Mitsubishi_Pajero https://en.wikipedia.org/wiki/Mitsubishi_Pajero
- elteto 3y agoPicture an ice box hurtling down the freeway at 100mph.
- BerislavLopac 3y ago"Nevera" means "storm"; specifically a storm on the sea.
- elteto 3y agoIn Spanish it most definitely does not. The most accurate translation would be ice box, or freezer, if you want to be super pedantic.
- BerislavLopac 3y agoBut then it's not a Spanish car. ;)
- euroderf 3y agoFor more stories about products badly named for international markets, heck out "International Business Blunders". It's the only business book that's made me laugh out loud.
- comprev 3y agoKona bicycles had to be rebranded in Portugal due to the translation being offensive/derogatory.

- pkphilip 3y agoI thought the McMurtry Spéirling was even faster: 0-60 in about 1.4s. https://www.youtube.com/watch?v=qVbir_r6Wb4 https://www.youtube.com/watch?v=qVbir_r6Wb4 The name is absolutely terrible though.
- earthnail 3y agoYes, but it's not road legal, although they're working on a road-legal version. Insanely awesome car though.
- pornel 3y agoIt uses 1.2 megawatt when accelerating. Amazing.
