Early this spring, word emerged on the Web that the 2013 Shelby GT500 could kick out as much as 620 horsepower. Shortly after we brought you the first spy shots of the new car. Today, we update the images with a new set that hints at a turbocharger replacing the supercharger under the hood.
A larger, higher-capacity intercooler spotted peeking out from behind the grille is the cue for the turbo speculation. It may simply be an upgrade to the supercharged model, but it might also indicate a need for yet more charge-cooling capability brought on by twin-turbocharging.
If it doesn't get a twin-turbo V-8, the next GT500 is expected to pack a 5.8-liter supercharged V-8 based on the current aluminum-block 5.4-liter engine. Either way, the new GT500 has the coming 2012 Chevrolet Camaro ZL1 squarely in its sights. If it's an improvement on the current GT500, Chevy will have a very hard time matching, let alone beating, the Shelby.
The rest of the GT500 shouldn't change much: it will look much like the current car, should have a similar suspension and performance package setup, and will of course be a solid-axle, rear-drive layout. Interior quality may see another uptick, and it'll likely get a few new tech features as Ford has been pushing hard in that segment lately.
Beyond that, it's a waiting game to see what the next Shelby GT500 will offer. We just can't wait to get one on track.
