We’re loving this new schtick from General Motors where they tease us with hot, new, fast sports cars and insane projected figures of their prowess—and then deliver real numbers that either live up to the hype or smack us silly by being even better than we were led to believe.
Since day one, the Corvette ZR1 has been billed as the most expensive and most powerful production Corvette in history, with an expected price tag around 100 grand and an estimated 620 hp at 6500 rpm and 600 lb-ft of torque at 4000 rpm from its supercharged LS9 6.2-liter V-8.
First GM surprised us with the SAE-certified numbers for the first factory-built Vette with forced induction: 638 hp and 604 lb-ft of torque, which equates to nearly 103 horses per liter—or just about 1.7 hp for each of the engine’s 376 cubic inches.
