Overview

• MIIT filings detail four 555 kW (744 hp) motors yielding a combined 2,220 kW (≈3,000 hp), a squared stance with 325/35/20 tires, aerodynamic upgrades, a 2,630 kg gross weight and a claimed 217 mph top speed.
• Regulatory documents reference a temporary boost mode that may unlock full output only above roughly 150 mph and likely for only a few seconds at a time.
• Experts led by Mate Rimac question the ability of LFP battery chemistry, motor/inverter hardware and tire traction to sustain multi-megawatt power on actual track runs.
• BYD has neither announced if the U9 Track Edition will enter production nor released on-track or dynamometer tests to substantiate the MIIT-filed figures.
• Theoretical power outputs would eclipse the Rimac Nevera R’s 2,107 hp peak but are fueling debate over peak versus sustained performance metrics in electric supercars.
