2020 Cadillac XT4 vs. 2020 Acura RDX: Which Is Better?

  • The 2020 Cadillac XT4 and the 2020 Acura RDX are both compact luxury crossovers that were new for 2019.

  • The XT4 is more efficient, and the RDX has better performance.

  • The Cadillac has a lower starting price, but the Acura is arguably a better value.

You have a ton of options when it comes to compact luxury SUVs. If you’re shopping on the more affordable side of this segment, there’s a good chance that the 2020 Acura RDX and the 2020 Cadillac XT4 have shown up on your shopping list. The RDX was fully redesigned for 2019 and the XT4 was an all-new model that year.

Let’s take a look at how these two SUVs measure up to each other and see which is better.

2020 Cadillac XT4 vs. 2020 Acura RDX exterior


The RDX is on the bigger side of the compact SUV segment, and it’s about six inches longer than the XT4. That means that the Cadillac has a smaller footprint, making it a little more maneuverable in tight spaces, but the size difference really isn’t that drastic. See the 2020 Cadillac XT4 models for sale near you

As for styling, both of these SUVs are adorned with sharp lines and big grilles representative of their respective brands. They both look modern and edgy, yet premium in their own ways. We think they both look great, and which one is better-looking is up to you. See the 2020 Acura RDX models for sale near you

2020 Cadillac XT4 vs. 2020 Acura RDX interior


Both of these crossovers are quite comfortable on the inside and have some of the best interior space in this class. If you’re looking for a compact luxury SUV you can actually use as a family vehicle for up to four people, both of these offer generous space for both passengers and cargo. Like everything in this class, things get a little tight with three people in the back seat.

As for quality and design, we think the Acura has an edge over the Cadillac. The interior of the XT4 isn’t bad, but it’s a bit bland and lags behind the Acura in refinement. The RDX uses nicer materials and a more modern design, resulting in a more premium feel than the XT4 throughout the interior.

2020 Cadillac XT4 vs. 2020 Acura RDX mechanicals


These SUVs both offer a sole engine under the hood. They both come standard with front-wheel drive and are upgradable to all-wheel drive.

2020 Acura RDX Engine

  • 2.0-liter turbocharged inline-four; 272 horsepower, 280 lb-ft of torque; up to 22 mpg city/28 mpg hwy

2020 Cadillac XT4 Engine

  • 2.0-liter turbocharged inline-four; 237 hp, 258 lb-ft of torque; up to 24 mpg city/30 mpg hwy

As you can see from the numbers, the Cadillac and the Acura are pretty similar mechanically. However, the RDX delivers stronger performance while the XT4 is a little better on gas. This makes the choice simple depending on your priorities. If you prioritize performance over fuel economy, check out the RDX, but if efficiency is more important to you, then the XT4 might be a better fit.

2020 Cadillac XT4 vs. 2020 Acura RDX tech


One of the few updates to the 2020 XT4 over the all-new 2019 model is the addition of some driver assistance technology as standard equipment. This includes forward-collision warning and automatic emergency braking. However, a lot of safety tech that comes standard on the RDX, including adaptive cruise control, lane-departure warning, and lane-keeping assist, will all cost you extra in the Cadillac. The XT4 does have a few cool features that the RDX lacks — such as a standard Teen Driving mode that limits speed and audio volume, and an optional rear camera mirror.

The XT4 comes standard with an 8-in touchscreen infotainment system that can also be controlled with a knob. It packs standard Android Auto and Apple CarPlay, and it’s easier to use than the historically frustrating CUE systems in Cadillac’s recent past. Every RDX comes with a 10.2-in infotainment system controlled via Acura’s True Touchpad interface, which has a bit of a learning curve. Apple CarPlay is standard, but Android Auto is disappointingly absent from the RDX.

2020 Cadillac XT4 vs. 2020 Acura RDX pricing


The XT4 is a bit more of a value proposition than the RDX. The XT4 has an affordable starting MSRP of just $35,695, and the RDX starts at $37,600. The XT4 can cross the $50k mark when you get into the higher trims and add AWD and other option packages, but a fully-loaded RDX with AWD is surprisingly affordable, topping out at less than $50k.

2020 Cadillac XT4 vs. 2020 Acura RDX conclusion


If affordability is your top priority in a compact luxury SUV, then you’d probably like the value proposition of a base-model XT4 since it’s more affordable and more fuel-efficient than a base RDX. That said, the RDX beats the XT4 in almost every other way. The Acura is also arguably a better value on the higher end since you need to add pricey option packages to the XT4 to get equipment that is standard on the RDX, such as a moonroof and some safety tech. We think most luxury shoppers will prefer the Acura with its better performance, nicer interior and more generous standard feature list. Find a Cadillac XT4 for sale or Find an Acura RDX for sale
