When customers walk into Coulter Tempe Cadillac, one of the most common questions they ask is: “Should I go with the Cadillac CT4 or step up to the CT5?” It’s a fair question.

Choosing between them really comes down to what you value most—size, features, or driving dynamics.

Let’s break it down so you can decide which option best fits your lifestyle.

Size and Presence

The first thing you’ll notice is size. The Cadillac CT4 is the smaller of the two, making it a great choice if you want a nimble luxury sedan that’s easy to maneuver around Tempe’s busy streets. Parking downtown or slipping into tighter spaces feels effortless.

The Cadillac CT5, on the other hand, offers a longer wheelbase and more interior space. Rear passengers will appreciate the extra legroom, and the trunk provides more cargo space for weekend getaways. If you’re the type who values a commanding presence on the road, the CT5’s larger stance delivers precisely that.

Performance and Driving Feel

Performance is where Cadillac shines, and both sedans bring plenty to the table.

The CT4 is powered by a turbocharged 2.0L engine that delivers quick acceleration, ideal for drivers who want responsive handling. There’s also a 2.7L turbocharged option available that provides additional power. Think of the CT4 as the sportier sibling—light on its feet, eager to carve through curves.

The CT5 offers a broader range of powertrains, including a 2.0L turbo and an available 3.0L twin-turbo V6. That V6 transforms the CT5 into a true performance sedan, delivering smooth, confident acceleration whether you’re merging onto the freeway or cruising down the open desert roads outside Tempe.

Both models are available with all-wheel drive, providing extra confidence in inclement weather or when you want more grip on the road.

Pricing and Value

Budget plays a role in any decision, and here’s where the CT4 makes a strong case. With a lower starting price, the Cadillac CT4 build appeals to drivers who want luxury at a price they’ll love. It’s a smart entry point into the Cadillac lineup, offering high-end premium features at a more accessible price.

The CT5 does cost more, but you’re paying for added space, stronger engine options, and a wider array of available technology. For many buyers, that extra investment is justified—especially if you plan to keep the car for years and want the most comfort and capability Cadillac offers.

Features and Technology

Inside, both sedans showcase Cadillac’s commitment to craftsmanship and innovation.
