We encourage you to compare the Cadillac XT5 vs. Lexus RX if you're searching for a powerful and premium midsize luxury SUV. While both of these models deliver an upscale and versatile driving experience, they're not necessarily equals in terms of performance, space, and utility.
See our detailed Lexus RX vs. Cadillac XT5 comparison guide below to discover where these models shine and which one ultimately comes out on top.
The Cadillac XT5 and Lexus RX lineups offer multiple engines to provide drivers with a choice of power levels. We'll be looking at the gas-powered options here, which narrows the scope of this comparison to two Cadillac engines and one Lexus powertrain (the remaining RX options feature hybrid or plug-in hybrid technology as well as model names other than RX 350). Let's start with some of the Lexus RX specs.
The Lexus RX 350 models are motivated by a 2.4-liter turbocharged four-cylinder engine paired with an eight-speed automatic transmission. Power is delivered to the front wheels in base form, but all-wheel drive is available.
With 275 horsepower on tap, the RX 350 SUVs provide ample performance. A 3,500-pound Lexus RX towing capacity is possible when this SUV is properly equipped. When fitted with standard FWD, the 2025 Lexus RX MPG ratings reach up to an EPA-estimated 22/29 MPG (City/Highway).1
Thankfully, the XT5 gives motorists a choice of two robust engines. The base configuration of the new Cadillac XT5 features FWD and a highly efficient 2.0-liter turbocharged four-cylinder engine producing 235 horsepower. In this configuration, the Cadillac XT5 MPG ratings match the Lexus model's peak fuel efficiency mentioned above. While FWD is standard, AWD is available on 2.0-liter turbo models.
The Cadillac brand lets you choose maximum power or efficiency in the XT5 lineup, thanks to the additional engine option: a 3.6-liter V-6. When fitted with this available six-cylinder unit, this luxury SUV delivers 310 horsepower – substantially more than the 275-horsepower Lexus RX 350. With either the 2.0-liter turbo or 3.6-liter V-6, your new XT5 features a nine-speed automatic transmission.
An advanced Twin-Clutch Sport Control AWD system comes standard on the high-powered XT5 Sport model, further boosting performance compared to the Lexus SUV. The V-6 models help the Cadillac XT5 towing capacity reach 3,500 pounds when this SUV is properly equipped.

At 192.5 inches long, the Lexus RX is about 3 inches longer than the Cadillac XT5, which measures 189.6 inches between its front and rear bumpers. Both models ride on a wheelbase of around 112 inches and provide ample seating in two rows. While the Cadillac XT5 dimensions are slightly smaller than the RX on the exterior, it's a different story inside, as you'll discover when we compare the cabin space of these two luxury SUVs below.

As you compare the dimensions of the Cadillac XT5 interior vs. the Lexus model, you'll find several areas where the XT5 once again outperforms its rival. The Cadillac XT5 seating capacity of five includes generous legroom in both rows, something that can't be said about the Lexus model.
Up front, XT5 drivers and front passengers will have 41.2 inches of legroom, more than the RX. But backseat occupants have even more reason to favor the Cadillac model, as the XT5 treats them to 39 inches of second-row legroom, compared to just 37.4 inches in the Lexus SUV.
Headroom and shoulder room are comparable in these two models, with over 39 inches of headroom and more than 58 inches of shoulder room in the front rows. It's a similar situation in the second row, where both SUVs are rather roomy.
While the Lexus RX seating capacity of five matches the Cadillac model, the XT5 is a better choice for second-row riders, thanks to its nearly 2 inches of additional legroom. See our new Cadillac specials if you're ready to trade up to a spacious XT5.

The trend of the XT5 outperforming its competition continues in the rear cargo area, with the Lexus RX cargo space lacking the capacity the Cadillac SUV affords.
Maximize your cargo-hauling abilities with a new XT5, offering an expansive 63 cubic feet of space behind the front row. The Lexus RX falls far behind in this area, offering a mere 46.2 cubic feet of maximum cargo capacity.
As you can see from our thorough review comparing the Cadillac XT5 vs. Lexus RX in specs like performance, legroom, and cargo space, the XT5 comes out on top in many measurements that matter most to luxury SUV shoppers.
