Those numbers are absolutely insane.
I recognize the one and only one reason why GM is building this car:
To embarrass that most expensive hypercars available.
McLaren P1: 903hp, $1,500,000 - $2,000,000 (USD, used)
Ferarri LaFerrari: 949 hp, $2,900,000 - $5,500,000 (USD, used)
Porsche 918 Spyder: 874 hp, $1,300,000 - $2,000,000 (USD, used)
2019 Corvette ZR1: 755 hp, Starts at $123,000 (USD, new)
C8 Corvette ZR1: 900 hp, Starts at $130,000 USD???
In the grand scheme of things, the ZR1 is a cheap, cheap, CHEAP car for what you're getting.
