Rimac/Bugatti CEO explains problems with Tesla Roadsters that go from 0 to 100 km/h faster than 1 second

Mate Rimac, CEO of supercar makers Rimac and Bugatti, has responded to Elon Musk’s claim that the new Tesla Roadster with thrusters will accelerate from 0 to 100 km/h in less than 1 second.

He sees some problems with it.

Tesla’s next-generation Roadster was first unveiled in 2017. It was supposed to go on sale in 2020, but has been delayed every year since.

Last year Elon Musk said it would come in 2024.

Last month, the CEO said he had a design meeting about the new Roadster, and they decided to “radically increase the design goals for the new Tesla Roadster.” Musk said the vehicle has been delayed again until next year, but he said Tesla plans to unveil an updated version later this year.

Musk again claimed that the vehicle would achieve sub-1-second acceleration from 0 to 60 mph with cold-air engines built by his rocket company SpaceX.

Rimac has been closely monitoring the Roadster program, as its Neverra electric hypercar delivers similar performance to what Tesla originally claimed for the Roadster.

After Tesla unveiled the prototype of the new Roadster, Rimac unveiled a new version of its supercar with similar specifications.

The Croatian electric supercar maker is also now in a better position than ever to compete with Tesla after Porsche invested in the company and let its founder and CEO, Mate Rimac, acquire legendary supercar maker Bugatti.

Recently, Rimac was asked on Facebook about Tesla’s claim of 0 to 100 km/h acceleration in less than 1 second in the new Roadster.

He said Rimac did the simulation. He thinks it’s possible, but it poses some weight problems:

It’s possible with thrusters. We did the simulation. The problem is that you let the air out in 2-3 seconds, and then you have a lot of dead weight that you carry with you (tanks, compressors, valves, nozzles, etc.). The same goes for fans – they just give you more grip, but you need about 30,000 Nm at the wheels to accelerate from 0 to 100 km/h in under 1 second, which means you have huge engines, inverters, gearboxes, drive shafts, etc. you need. the car has to be super light, otherwise you can’t create much excess downforce with the fans, because the tires would get overloaded very quickly on any kind of “normal supercar” weight car, especially electric. And then you carry the weight with you again if you don’t drive 0-100 km/h. So thrusters are really the only way to go. But it also brings many disadvantages.

It sounds like Rimac isn’t sold on the idea of ​​putting cold air confidence in its supercars.

Can Tesla prove them wrong?

Electrek’s Take

It sounds like a fair assessment. There’s a lot of hardware in the car, almost entirely just to accelerate faster, which you probably won’t be able to do on public roads with the thrusters.

The rest of the time, your car’s performance will deteriorate due to the extra weight.

Tesla originally talked about the new Roadster with a range of more than 600 miles. That was one of the things I was most excited about with the Roadster.

However, Musk has since said that Tesla is not interested in making cars with a range of more than 400 miles, and interestingly, this is for the same reason as the problem highlighted by Rimac. People rarely drive more than 650 kilometers in one go and the rest of the time you carry a super large and heavy battery pack with you for no reason.

In his recent update on the new Roadster, Musk made no mention of the range. It will be interesting to see if a 900 kilometer range is still in the plans for the new Roadster.
