The answer may surprise you, but we're not going to ruin it for you. The head-to-head does come down to the wire, however.
The video, by way of Drag Times, shows two passes down the 1/4-mile, pitting the hottest version of the Model S against the C7 Corvette with the Z51 package and six-speed automatic transmission. Whether the seven-speed manual would do any better is open to debate, though it would certainly rely more heavily on the driver's abilities.
This isn't the first time we've seen the Model S on the straight strip, either. A previous video showed the electric sedan capable of runs in the 12.371-second range (trouncing a convertible Viper in the process), a stout mark by any propulsion standards. Likewise, the first customer-owned Stingray hit the strip and turned in a 12.23-second run.
Considering the straight line isn't even the Stingray's greatest strength, there's no real debate to be had over which is the better performance car, but that the Model S can hang with America's best pure sports car in even one dimension of ability is impressive.
What we'd like to see next: the 600-mile road trip race. Wonder which would win that?
