Is the Cadillac CT4 or CT5 Bigger?
The bigger of these two is the 2026 Cadillac CT5, which stretches xxx inches bumper to bumper -- long enough to place it firmly in the midsize sedan segment. The CT4, being a compact sport sedan, casts a slightly smaller shadow, with an overall length of xxx inches.
Naturally, the larger CT5 boasts more rear legroom and cargo volume than its smaller showroom sibling, so if you're looking for a sedan with room for the family, this one is for you. If maximizing space isn't as important as maximizing driving thrills, the CT4 is bestowed with the natural lithe athleticism that can only be found in a smaller car.
2026 Cadillac CT4
- Overall Length (in.): 187.2
- Rear Legroom (in.): 33.4
- Trunk Volume (cu. ft.): 10.7
2026 Cadillac CT5
- Overall Length (in.): 193.8
- Rear Legroom (in.): 37.9
- Trunk Volume (cu. ft.): 11.9
Are the CT4 & CT5 Performance Cars?
Yes. The Cadillac V-Series lineup needs no introduction to longtime fans of the brand, as this trim name has graced the trunk lids and flanks of some of the best handling sport sedans of this century. Currently, both the 2026 Cadillac CT4 and CT5 can be had in V-Series trim, and you can also choose to upgrade further to the CT4-V and CT5-V Blackwing -- two cars that have set benchmarks for how well they drive.
You don't need to buy a CT5-V or CT4-V Blackwing in Texas to have fun behind the wheel, though. Even the entry-level trims are tuned to leave grinning as you come out of a corner or power up an onramp and several engine options give you the power to choose just how much oomph you want at your disposal. Both cars have been dialed in by engineers with a level of precision normally reserved for dedicated sports cars, not luxury four-door sedans designed for commutes, errands and family trips.
