The arrival of a new Chevrolet Camaro means that the anticipation starts for the high-performance versions. These new spy shots show what looks to be the 2017 Chevrolet Camaro ZL1, with certain clues like aerodynamic bits and larger wheels and tires giving the prototype away as an upgraded version of the sixth-gen musclecar.

Though it’s heavily camouflaged, this Camaro ZL1 prototype clearly offers a different body kit than the standard 2016 Chevrolet Camaro, with a lower front fascia, a possible hood scoop, and a rear spoiler visible. The larger wheels and tires appear to be taken from the outgoing Chevrolet Camaro ZL1, hinting at a sharper chassis tune under the skin. Quad tailpipes out back are also slightly larger than the Camaro SS, giving us an indication that the ZL1 will sound even louder and meaner than the Camaro SS model’s LT1 V-8.

Like we previously reported, the 2017 Chevrolet Camaro ZL1 is tipped to use a version of the supercharged, 6.2-liter LT4 V-8 engine in the Corvette Z06. Though it may not quite match the Corvette’s 650-hp output, even a bump up to 600 hp would be a significant upgrade over the outgoing Camaro ZL1, which made 580 hp. This performance of the new ZL1 will be especially impressive when you consider the car’s Alpha platform shared with the Cadillac ATS, which results in a significant weight loss compared with the fifth-gen Camaro.

The 2017 Chevrolet Camaro ZL1 should debut sometime in early 2016, possibly at the Detroit auto show in January. Stay tuned for more details on this upcoming musclecar as we learn more about its upgrades, and check out the spy photos in the meantime.
