Mate Rimac, CEO of supercar makers Rimac and Bugatti, has commented on Elon Musk’s declare that the brand new Tesla Roadster goes to speed up from 0 to 60 mph in lower than 1 second with thrusters.
He sees some issues with it.
Tesla’s next-generation Roadster was first unveiled again in 2017. It was first supposed to return in 2020, however it has been delayed yearly since.
Final yr, Elon Musk stated that it will are available 2024.
Final month, the CEO stated that he had a design assembly in regards to the new Roadster, and so they determined to “radically improve the design objectives for the brand new Tesla Roadster.” Musk stated that the automobile is delayed once more till subsequent yr, however he stated that Tesla plans to unveil an up to date model later this yr.
Musk once more claimed that the automobile would obtain sub-1-second 0 to 60 mph acceleration with chilly air thrusters constructed by his rocket firm, SpaceX.
Rimac has been retaining shut monitor of the Roadster program as its Neverra electrical hypercar is attaining comparable efficiency that Tesla has been initially claiming for the Roadster.
After Tesla unveiled the prototype of the brand new Roadster, Rimac unveiled a brand new model of its supercar with comparable specs.
The Croatian electrical supercar producer can also be now in a greater than place than ever to compete with Tesla after Porsche invested within the firm and had its founder and CEO, Mate Rimac, takeover legendary supercar maker Bugatti.
Not too long ago, Rimac was requested on Fb about Tesla’s declare of sub-1-second 0 to 60 mph acceleration within the new Roadster.
He stated that Rimac did the simulation. He thinks it’s doable, however it creates some weight points:
It’s doable with thrusters. We did the simulation. The issue is that you just launch the air in 2-3 seconds, after which you’ve gotten lots of lifeless weight that you’re carrying round (tanks, compressors, valves, nozzles, and so forth.). Identical with followers – they simply provide you with extra grip, however you want one thing like 30.000 Nm on the wheels to speed up under 1 sec 0-100 km/h, which implies you want huge motors, inverters, gearboxes, driveshafts, and so forth. Plus, the automotive needs to be tremendous gentle as in any other case you may’t create lots of extra downforce with the followers because the tires can be overloaded very quick with any type of automotive with “regular supercar” weight, particularly electrical. After which once more you’re carrying the burden with you when you find yourself not doing 0-100 km/h. So thrusters are actually the one option to go. However it brings lots of downsides as properly.
It appears like Rimac isn’t offered on the thought of placing chilly air trusters in its supercars.
Can Tesla show them flawed?
Electrek’s Take
It appears like a good evaluation. There’s lots of {hardware} within the automotive, nearly fully simply to speed up quicker, which you’ll seemingly not be capable to do on public roads with the thrusters.
The remainder of the time, it should make your automotive’s efficiency worse with the added weight.
Initially, Tesla talked in regards to the new Roadster having over 600 miles (965 km) of vary. That was one of many issues I used to be most enthusiastic about with the Roadster.
Nonetheless, since then, Musk has stated that Tesla isn’t considering making automobiles with greater than 400 miles of vary and apparently, it’s for the same purpose as the issue highlighted by Rimac. Individuals hardly ever drive greater than 400 miles in a single go and the remainder of the time, you’re carrying a brilliant giant and heavy battery pack for no purpose.
Along with his latest replace on the brand new Roadster, Musk didn’t point out the vary. It is going to be fascinating to see if 600 miles of vary continues to be within the plans for the brand new Roadster.
