We've got our first shots of the updated Camaro ZL1 that was caught testing in Metro Detroit.

While the front-end doesn't change much, the rear end has been toned down slightly.

Along with the new rear bumper, it looks like there's another camera in the rear spoiler, above the standard one near the license plate.

The updated ZL1 is still expected to rock a 6.2-liter LT4 churning out 650 hp and 650 lb-ft of torque, or there abouts. We don't expect any changes in its transmissions.

The official reveal, with all pertinent details, is expected in the coming months.
