Sponsored Links The 2021 Cadillac CT5 represents the second model year of the luxury sedan, for which it receives several new features and changes. Here’s exactly what was new for the 2021 CT5. Model Line The 2021 Cadillac CT5 model line remains the same as it was in 2020, consisting of Luxury, Premium Luxury, Sport, and V-Series (per Cadillac’s Y trim level strategy). All models are available in either rear-wheel or all-wheel-drivetrain configurations. Exterior On the outside, the 2021 Cadillac CT5 sees the deletion of two existing colors and the addition of three new ones. The two deleted hues are Red Obsession Tintcoat and Royal Spice Metallic. Both colors were available at an extra charge for the 2020 model year, and Royal Spice Metallic was a promotional color available only on the CT5-V and the CT5 Sport.
