The 2026 Cadillac CT5 will introduce a new exterior color called Coastal Blue Metallic to its lineup.

This Coastal Blue Metallic finish will be available as a $625 option for the CT5 Premium Luxury and CT5 Sport trims. The new shade can be paired with all available interior colors.

It's worth noting that Coastal Blue Metallic has been offered on the high-performance CT5-V and CT5-V Blackwing models since the 2024 model year.

Under the hood, the 2026 Cadillac CT5 carries over the same engine lineup as the previous 2025 model. The base option is a turbocharged 2.0-liter I4 LSY gasoline engine producing 237 horsepower and 350 Nm of torque. An optional twin-turbocharged 3.0-liter V6 LGY gasoline engine delivers 335 horsepower and 565 Nm of torque. Both engines are paired with GM's 10-speed automatic transmission.
