The 2026 Acura Integra returns 33 mpg combined against the Cadillac CT4’s 26, offers 24.3 cubic feet of liftback cargo space the CT4 cannot match, and has 4.0 inches more rear legroom. The Integra also has ten standard airbags against eight and an available 6-speed manual the CT4 does not offer.
The CT4 is Cadillac’s compact sedan and it has a real chassis underneath — rear-wheel drive, adaptive dampers as standard, and the excellent CT4-V above it.
The Integra answers with efficiency, practicality and space, and it does so for less money.

33 mpg combined against 26 is a 27 percent difference. Over 12,000 miles a year that is roughly 100 gallons of fuel, every year.
Part of that is the drivetrain layout — the Integra is front-drive with a CVT in its most efficient configuration, and the CT4 is rear-drive with a conventional 8-speed automatic. Both approaches have merits, but on fuel cost this one is not close.

The Integra’s liftback gives 24.3 cubic feet of cargo space through a wide, square opening. The CT4 is a conventional sedan with a boot lid.
Rear legroom is where the gap is starkest: 37.4 inches against 33.4. Four inches is not a subtle difference — it is the difference between a usable back seat and an occasional one.

The Integra A-Spec with Technology Package offers a close-ratio 6-speed manual with a limited-slip differential and automatic rev-matching. Cadillac does not offer a manual CT4 in the standard range.
Adaptive cruise control is standard on the Integra and an extra cost on the CT4. The Integra has ten standard airbags including rear-passenger outboard side airbags; the CT4 has eight and does not offer them.
The Integra Technology Package also brings a 9-inch touchscreen, the 16-speaker ELS STUDIO 3D system, wireless Apple CarPlay and Android Auto, a wireless charging pad and a head-up display.

The CT4 is rear-wheel drive with an Adaptive Damper System as standard equipment, where the Integra’s adaptive dampers are an option on one trim. For a driver who prioritizes chassis balance, the Cadillac’s fundamental layout is the more appealing one.
The CT4-V and CT4-V Blackwing above the base car are among the best driver’s cars General Motors currently makes. Nothing in the standard Integra range answers the Blackwing.
Cadillac incentives on the CT4 are often substantial, and GM’s dealer and service network is denser than Acura’s in many parts of Northern California.
The Integra is the better everyday car: far more efficient, far more practical, four inches roomier in the back, better equipped for safety, and less expensive.
The CT4 is the better driver’s car in its fundamentals, and the V models above it are in a different league entirely.
If you want the Integra with a real performance edge, the Integra Type S is the one to drive.
Yes, substantially. The Integra returns 33 mpg combined in its front-drive CVT configuration against 26 mpg combined for the rear-drive CT4 with the 8-speed automatic.
The Integra has 37.4 inches of rear legroom against 33.4 inches in the CT4 — a 4.0-inch advantage.
Not in the standard range. The Acura Integra offers a close-ratio 6-speed manual with a limited-slip differential and rev-matching on the A-Spec with Technology Package.
The Integra has ten standard airbags including two rear-passenger outboard side airbags. The CT4 has eight and does not offer rear-passenger outboard side airbags.
Yes, and as standard equipment — this is one area where the Cadillac leads. On the Integra the Adaptive Damper System is available with the A-Spec and Technology Package.
