To begin, let's first take a look at the trim levels you will find as you search for a new Cadillac CT5:
The standard engine of the Cadillac CT5 is the 2.0-liter turbocharged four-cylinder that produces 237 horsepower and 258 pound-feet of torque. It's paired with a 10-speed automatic transmission, which you'll also have if you opt for the 3.0-liter twin-turbo V-6. Available for the CT5 Premium Luxury and standard in the CT5-V, the former delivers 335 horsepower and 405 pound-feet of torque with the V-6, while the latter brings you up to 360 horsepower.
At the pinnacle, the CT5-V Blackwing is equipped with the 6.2-liter supercharged V-8 engine. This motor revs to the tune of 668 horsepower and 659 pound-feet of torque for undisputed track dominance. These 2026 Cadillac CT5 specs match with a standard six-speed manual transmission; a 10-speed automatic is available.
Just like there are differences in engines, there are differences in drivetrains, which impact the MPG ratings you can earn. The CT5 achieves an EPA-estimated 22/31/26 MPG (City/Highway/Combined) fuel economy rating with the standard engine and RWD.1 Upgrade to AWD, and you experience an EPA-estimated 21/30/24 MPG (City/Highway/Combined).2
With the available 3.0-liter twin-turbo V-6, the CT5 gets an EPA-estimated 19/28/22 MPG (City/Highway/Combined) with RWD3 and an EPA-estimated 18/27/21 MPG (City/Highway/Combined) with AWD.4
The 2026 CT5-V renders an EPA-estimated 18/27/21 MPG (City/Highway/Combined) rating with RWD5 and an EPA-estimated 17/26/20 MPG (City/Highway/Combined) with AWD.6
Finally, the CT5-V Blackwing equipped with the 6.2-liter supercharged V-8 engine nets an EPA-estimated 13/20/15 MPG (City/Highway/Combined)7 with both the manual and automatic transmission.
The CT5 interior offers a premium experience built around passenger comfort. This is reflected in its generous dimensions. Up front, you have 42.4 inches of legroom and 39 inches of headroom. Meanwhile, your guests in the rear can stretch out and enjoy 37.9 inches of legroom and 36.6 inches of headroom, making the second row accommodating for children and adults alike; the CT5-V Blackwing boasts 37 inches of second-row legroom.
Cadillac CT5 trunk space comes in at 11.9 cubic feet across the board, practical for road trips and daily errands alike.
The CT5 provides spirited handling and a commodious cabin, thanks in large part to its exterior dimensions. Key 2026 Cadillac CT5 specs include the following:
