The difference in wheelbase between the CT4 and CT5 is a matter of five inches. The CT5 has a 116-inch wheelbase and a length of 193.8 inches. At 74.1 inches wide and 57.2 inches tall, the CT5 also offers 37.9 inches of rear legroom. 

Conversely, the CT4 is 187.2 inches long, 71.4 inches wide, and 56 inches tall, with 33.4 inches of rear legroom. The Cadillac CT4 and CT5 can seat up to five passengers. 

The Cadillac CT4 has up to 10.7 cubic feet of cargo space. It also features leather seating and a 12-inch diagonal HD driver display with available heads-up display (HUD) on the Premium Luxury model. Cadillac fits alloy driver pedals on the Sport trim.

In comparison, the CT5 has 11.9 cubic feet of cargo capacity in the trunk. Available features include leather, driver memory settings, and wireless phone charging. LED ambient interior lighting also gives this midsize Cadillac a sumptuous feel. 

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: 

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 IIHS hasn’t rated the Cadillac CT4 or the CT5. The NHTSA doesn’t offer any awards for the CT4, but the CT5 FWD and AWD models earn a five-star overall safety rating. Standard safety features on both Cadillac sedans include:

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. The CT5 may not be the most fuel-efficient car on the road, but it certainly keeps up with the pack. If you use your vehicle for business but want to impress your passengers with some power, the CT5 can get the job done.
