  • Underwhelming base engine
  • Dull handling
  • Low-rent cabin

New for 2021

Thinking of leasing a Cadillac CT5?

The U.S. News Best Price Program saves users an average of $3,206 off the MSRP, and a lower price equals lower monthly lease payments. That means you could see a savings of $90 a month on a 36-month lease.

Is the Cadillac CT5 a Good Car?

No, the CT5 is not a good luxury midsize car. The cabin is a little cramped, and most materials are unimpressive. Furthermore, cargo space is lacking. Neither of this Cadillac's engine choices – a standard turbocharged four-cylinder and an optional twin-turbo V6 – are particularly impressive. The base setup can feel weak, while the upgraded mill has a bit of turbo lag. Handling is numb and lacks the athleticism of sportier rival sedans.

The CT5’s positives include a long list of features, a user-friendly infotainment system, a comfortable ride, and expansive rear legroom, but many class rivals share those attributes along with many more.

Should I Buy the Cadillac CT5?

No, you shouldn't buy the Cadillac CT5. The car's biggest appeal compared to the rest of the class is a sub-$37,000 sticker price and a decent list of standard equipment, but your money is still better spent elsewhere. The Acura TLX has similar pricing, but it’s a better car overall than the CT5. If you can stretch your budget, consider a class leader like the BMW 5 Series instead.

2020 vs. 2021 Cadillac CT5: What’s the Difference?

Introduced as an all-new model for 2020, the CT5 sees several changes for 2021. Standard Android Auto and Apple CarPlay now have wireless capability, and a 12-inch fully digital instrument cluster is newly optional.

Another notable upgrade is the introduction of Cadillac's Super Cruise feature to the CT5 as an option. This partially automated driving assistance system works on certain highways to help maintain a set distance between you and other vehicles while also tracing lane markings to help steer the car. It may sound like a fully autonomous system, but Super Cruise still requires the driver to be in control of the vehicle. You'll also be alerted if more attention to the road is needed.

How Much Does the Cadillac CT5 Cost?

The 2021 Cadillac CT5 has the lowest base price among luxury midsize cars, at $36,995. Only a couple of other segment rivals retail for under $40,000, while more than half of the class starts at over $50,000.

There are three higher trims of the CT5 that start at $40,795, $41,795, and $47,795. Rear-wheel drive is standard in every model, and all-wheel drive is optional for $2,000. The CT5 comes standard with a turbocharged four-cylinder engine, and it's available with a twin-turbocharged V6 for as little as $45,645.

When loaded up with most major options, the CT5’s price can exceed $69,000.

Cadillac CT5 Versus the Competition

Cadillac CT5 vs. Acura TLX

The Acura TLX is also one of the lowest-priced cars in the luxury midsize car class, retailing for only a few hundred dollars more than the base CT5. And while the CT5 can cost almost $70,000, the TLX tops out at around $48,000. Fully redesigned for 2021, the TLX sports a cool cabin that's equal parts high-end materials and sports car-inspired design. You'll get better performance with the Acura, which has a well-balanced ride and handling and a peppy standard engine. By contrast, the Cadillac has loads of rear legroom and more user-friendly features. Both cars have a similar list of standard and optional features.

Overall, the TLX is a slightly better choice than the CT5, but there are some caveats. The Acura's back seat is tight, and the infotainment system has a slight learning curve.

Cadillac CT5 vs. 5 Series

The BMW 5 Series is an excellent car that has practically everything you could want from a luxury sedan, including a welcoming back seat, a huge trunk, and class-leading performance. The 5 Series handles with agility and offers up a half-dozen very capable engine choices. The only thing that might give you pause is the 5 Series' high base price of about $54,000, and upper performance-oriented trims eclipse six figures.

CT5 Interior: Misses the Mark

CT5 Cargo Space

The 2021 Cadillac CT5 has just 11.9 cubic feet of trunk space. Among luxury midsize cars, only a handful of rivals have less storage room, and that's because they're either coupe, convertible, or hybrid models. To make things worse, the trunk is narrow and has some odd sculpting that can hinder fitting items of a certain size when the second-row seats are folded down.

How Many People Does the CT5 Seat?

This Cadillac sedan seats five people. The front positions offer plenty of power adjustments, but side support is a little lacking. Rear-seat accommodations are decent for a car in this class. There's about 38 inches of legroom, a total surpassed by only a few rivals. However, the sloping roofline cuts into headroom.

CT5 and Child Car Seats

There are two complete sets of LATCH connectors for the CT5’s rear outboard seats, along with a tether anchor for the rear middle seat. The lower anchors are easy to find, and most types of child car seats fit easily in the second row with plenty of space.

CT5 Interior Quality

One of the CT5's most glaring weaknesses is its use of hard plastics and other materials that don’t stack up favorably compared to class rivals. Some controls and pieces look like they were borrowed from a GM parts bin, and the so-so overall design is more reminiscent of a nonluxury brand.

CT5 Infotainment, Bluetooth, and Navigation

Technology is one of this Caddy’s strong suits. The 10-inch touch screen has impressive details and graphics, and it's very responsive to your touches. The menu structure is also straightforward.

A rotary control knob on the center console provides another way to command the infotainment system. Additionally, there are buttons on the center stack for things like climate adjustments. Audio volume and tuning are also controlled by knobs, but these dials are placed right next to each other and may cause some inadvertent mistakes.

  • Standard infotainment features: a 10-inch touch screen, voice recognition, three USB ports, wireless Android Auto and Apple CarPlay, a nine-speaker stereo, satellite radio, HD Radio, Bluetooth, and a Wi-Fi hot spot
  • Available infotainment features: navigation, a 15-speaker Bose premium stereo, and wireless device charging
  • Additional standard features: proximity keyless entry, remote start, a universal garage door opener, and dual-zone automatic climate control
  • Other available features: a 12-inch digital instrument cluster, a dual-pane sunroof, an auto-dimming rearview mirror, ambient interior lighting, and cabin air ionization

CT5 Performance: Snoozefest

CT5 Engine

The Cadillac CT5 comes standard with a turbocharged four-cylinder engine good for 237 horsepower, which is one of the lowest ratings in the class. Reviews are mixed; some critics say acceleration is sufficient, while others find it a little underpowered.

A better option is a twin-turbocharged V6. In the CT5 Premium Luxury, it puts out 335 horsepower, and in the V-Series trim it makes 360 horses. After a split-second of turbo lag, power comes on strong and steady.

Both engines are paired with a 10-speed automatic transmission. This is a high point of the powertrain, as it's responsive and knocks off timely shifts.

CT5 Gas Mileage

Outfitted with its base engine and standard rear-wheel drive, the 2021 CT5 gets an EPA-estimated 23 mpg in the city and 32 mpg on the highway. Those figures are about average for the luxury midsize car class. Getting the four-cylinder engine with all-wheel drive results in fuel economy of 21 mpg in the city and 31 mpg on the highway.

The CT5 with its twin-turbo V6 engine gets between 19/28 mpg city/highway and 18/26 mpg city/highway, depending on trim and whether you get rear- or all-wheel drive.

CT5 Ride and Handling

The best part about the CT5's driving dynamics is its plush ride. However, don't look to this Caddy for an engaging experience. Steering lacks feedback from the road, and handling is pretty uninspiring overall.

The Final Call

The 2021 Cadillac CT5 tries to make a splash in the competitive luxury midsize car segment, but it barely causes a ripple. Its weaknesses, which include a subpar interior, dull performance, and tiny trunk, are too glaring to ignore in the face of excellent competition.

Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "Although the CT5 is meant to be Cadillac's prize fighter, missteps with chassis tuning and interior richness knock it out of contention." -- Car and Driver
  • "The CT5’s basic turbocharged 4-cylinder engine is down on power, its driving dynamics are not as enjoyable, and the interior and technology feel a step behind the competition." -- Kelley Blue Book
