Stately sedans bearing the Cadillac emblem have their own place in history, from escorting Presidents to various functions to bearing celebrities from gig to gig. The CT4 and CT5 aren’t necessarily tasked with the same functions as their predecessors, but the balance between luxury and power remains at the heart of both sedans. Perhaps that’s why choosing between them presents such a difficult task.

Upon first glance, the Cadillac CT4 and CT5 share nearly identical new design silhouettes. However, the CT5 features a characteristic uptick in the rear body line that pinches the rear window into a smaller triangle. The CT4 is technically a compact sedan, while the larger CT5 is considered midsize. V-Series models of the two luxury sedans infuse the bodywork with a sporty look indicative of the more powerful engine beneath the hood.
To saddle up any Cadillac sedan as a towing vehicle doesn’t do the ponies housed within the engine bay justice. However, both the CT4 and CT5 can tow up to 1,000 pounds when properly equipped. However, you’re better off purchasing the XT4 and XT5 variants or, better yet, tasking the Cadillac Escalade with the job.
The Cadillac CT4 and CT5 share the same 2.0-liter twin-scroll turbocharged four-cylinder engine. This base powertrain offers 237 horsepower and 258 lb-ft of torque in both models. However, the CT4 also has the option of a turbocharged 2.7-liter four-cylinder with 325 horsepower and 280 lb-ft of torque.
Besides the 2.0-liter engine paired with an eight-speed automatic transmission, the CT5 features a 3.0-liter twin-turbocharged engine mated to a 10-speed automatic transmission. This larger powerplant delivers 360 horsepower and 405 lb-ft of torque. Both the CT4 and CT5 can be purchased in rear-wheel or all-wheel drive.
The following table compares fuel efficiency for the CT4, CT5, and the V-Series variants of both models:
Model | Engine | City MPG | Highway MPG | Combined MPG |
CT4 RWD | 2.0-liter | 22 | 32 | 26 |
2.7-liter | 21 | 31 | 25 | |
CT4 AWD | 2.0-liter | 21 | 31 | 25 |
2.7-liter | 21 | 29 | 24 | |
CT4-V | 2.7-liter | 20 | 29 | 23 |
3.6-liter | 16 | 24 | 19 | |

6.2-liter | 13 | 21 | 16 | |
6.2-liter manual | 13 | 21 | 15 |
As you can see, the CT4-V and CT5-V models are more performance-oriented than fuel-efficient. However, the most fuel-efficient model is the CT5 in rear-wheel drive, at 27 combined MPG. The 6.2-liter engines in the CT5-V rank among the least fuel-efficient, next to the CT4-V Blackwing and CT5-V Blackwing, which offer a high-performance driving experience.

The Cadillac CT4 is a luxury sedan for those who aren’t sure they want to or can purchase a more expensive vehicle. One of the advantages of buying a used car is that you can avoid putting the first mark on the seats or scratch in the paint, but with a CT4, you won’t feel like you’re overextending yourself. Instead, you can enjoy the drive and that sense of importance every Cadillac seems to exude.
If you’re not worried about how long you can get a car loan for, the Cadillac CT5 and CT5-V offer enthusiasts a chance to treat themselves without breaking the bank.

Cadillac discontinued the CTS for the 2019 model year. However, the CT5 assumed its position in the Cadillac lineup and continues representing the luxury brand in the midsize sedan segment.

The CT4 and the CT5 share a similar base powerplant. However, the CT5 has a 3.0-liter engine in addition to the base 2.0-liter, with more horsepower and torque. V-Series variants of both luxury sedans also put more power to the pavement.
Between the Cadillac CT4 and CT5, the CT5 has a larger available engine with a 10-speed automatic transmission. However, the CT4 is more affordably priced and has a shorter wheelbase.

Consumers looking for a midsize luxury sedan typically gravitate toward the Cadillac CT5. This larger model has more trunk space, bigger legroom, and is actually more fuel-efficient than its smaller counterpart, the CT4.
