This trim jump changes the engine from 2.0L I4 mild-hybrid Turbo to 2.0L I4 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the AMG CLA 35 if the 2.0L I4 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the AMG CLA 45 S only when the 2.0L I4 Turbo powertrain is the reason you are moving higher in the lineup.
