The future Chevrolet Camaro Z28 has been caught testing again, this time somewhere in San Diego. The car is expected to be unveiled in 2011, with sales to begin in 2012.

Under the hood there will be GM's 6.2-liter supercharged V8 that produces 556HP and that was also used in the Cadillac CTS-V. Stopping power will come from the 6-piston front and 4-piston rear calipers.

The 2012 Camaro Z28, already confirmed by GM will be will be distinguished by enlarged air intakes at the extreme, a larger bubble on the hood to make room for the supersized engine, quad exhaust with dual pipes on each side, rims inspired by the ones from the CTS-V, and 20" SP550 anodized black (20×10 in the front and 20×11 in the rear) wrapped in Goodyear tires.

Previous rumors suggest that the Z28 version will be built on a new Alpha platform (and not the Zeta like the current car).
