While the 2019 Cadillac ATS will appear on your dealer lot this fall, this is one big change for this performance luxury vehicle in 2019.

This applies to both the ATS and the ATS-V versions of the car. You may see a couple minor changes like a new paint color or an updated upholstery option inside, but the nuts and bolts will remain the same while the Lansing plant is retooled to continue Cadillac production focusing on new models and ideas for the future. However, that doesn't mean the ATS is lacking in any department. Read on to unearth all of the luxury amenities and surprising power found on the 2019 Cadillac ATS.
