When the 2015 Corvette Z06 debuts at the 2014 Detroit Auto Show next week, it will do so with enough firepower to level the playing field while throwing massive tree stumps at the competition.
How much? Try 620 horses charging out of the gate with 650 lb-ft of redwood-caber tossing torque, courtesy of the new Z06′s supercharged LT4 V8. The figures would put the 2015 model over the previous Z06′s stats by 115 ponies and 180 lb-ft of torque from its naturally aspirated 7-liter, and the ZR1 by 46 lb-ft.
As for how the info got out: Metadata. A Jalopnik reader googled for information regarding the Z06, bringing up a search result whose meta description spelled out what the new Corvette would be packing under the hood; General Motors has since rewritten the description, omitting the leaked figures.
