Mate Rimac, the 37-year-old govt who shook up the supercar world along with his all-electric, quad-motor Nevera in 2022, is casting aspersions on the Yangwang U9 Nürburgring Version simply days after its announcement and debut, particularly focusing on its claimed 3,000-horsepower output. Though the CEO of Bugatti Rimac could also be smarting from the Nevera shedding its Nürburgring observe file to a different Chinese language EV, the Xiaomi SU7, in June, he nonetheless exhibits his work in feedback on the Fb group Apex Automotor, saying that the Yangwang U9’s motors would possibly be capable of theoretically produce its said output, however the lithium-iron phosphate (LFP) battery chemistry would not be capable of ship that a lot juice “even for 1 second.”
Real Doubts Or Bitter Grapes?
Rimac’s feedback on the Yangwang U9 have been reportedly eliminated by Fb for not being related, however Apex Automotor administrator Dan M Henderson copied and pasted the CEO’s work right into a put up of its personal. Rimac says that the 80-kilowatt-hour LFP battery within the Yangwang U9 would wish to have a discharge charge of 20+C (which means an entire and complete discharge in three minutes) with a purpose to produce the claimed energy output – one thing he says is unlikely.
“Since most Chinese language EVs use LFP cells, I doubt that any of them can ship 20+C discharge charges (even for 1 second) that might be wanted to ship 2-plus megawatts [2,683 horsepower] of energy.”

Rimac’s declare is that LFP cells, which many Chinese language EVs use as a result of they’re cheaper to provide and extra immune to degradation, merely aren’t able to the discharge charge required to make the Yangwang U9’s quad 744-hp motors churn at full output. He additionally factors out that his personal creation, the Nevera R, can put out 1.5 MW (2,012 hp) and will probably put down extra if all the powertrain have been beefed up, however even at its present degree, the automobile is restricted just by nature of contemporary high-performance rubber. At full energy, the Nevera R exceeds the traction restrict of its tires till it is going 100 miles per hour, and one thing with the claimed 3,000 hp of the Yangwang U9 Observe/Nürburgring Version would most likely be grip-limited till 150 mph or extra.
There Would possibly Be Some Fudged Numbers
If Rimac’s claims are correct, then it is attainable that Yangwang father or mother firm BYD is jockeying its flagship efficiency EV’s energy output a bit. It is seemingly that every motor can certainly produce a peak of 744 hp by itself, however maybe not all 4 on the identical time. Such a powertrain format would nonetheless give the higher-performance U9 unimaginable flexibility on the observe, routing full energy to the wheels with essentially the most grip on nook exit and turning every motor right into a generator for tighter turn-in on nook entry and improved stability all over the place else.
For what it is value, BYD hasn’t introduced any plans to set a brand new observe file on the Nürburgring, which might put the Rimac Nevera within the bronze place on the rostrum if profitable. Even when that does occur, Mate Rimac can nonetheless lean on the 2 dozen efficiency information the Nevera R set final month, together with when it beat the Koenigsegg Jesko Absolut by greater than 2 seconds within the 0-249-0-mph acceleration and braking take a look at. These achievements are protected from the Chinese language for awhile, at the very least so long as the CEO’s claims about discharge charges and traction limitations show true.
