Chevrolet introduced LT1, pairing LT appearance/content with the SS's 455-hp V8; revised the SS nose from the 2019 treatment; and made a 10-speed automatic available with the 3.6-liter V6.
LT1 created a lower-priced V8 entry distinct from the more chassis-equipped SS; published copy should not collapse the two trims into one specification.
The powertrain and identification notes below preserve configuration and model-year boundaries rather than treating every 2020 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.
