The sixth generation launched on GM's Alpha platform (shared with the Cadillac ATS/CTS) — significantly lighter than the outgoing Zeta car. It brought the first turbocharged four-cylinder Camaro since the Iron Duke (275 hp — more than triple the old four), and an SS with the C7 Corvette's 6.2 L LT1 at 455 hp: the most powerful Camaro SS ever built at launch.
The powertrain and identification notes below preserve configuration and model-year boundaries rather than treating every 2016 Camaro alike. Ratings use the measurement convention of their period, and visual cues are only a starting point: the VIN, factory labels, drivetrain identifiers, and surviving documentation should agree.
