2021 Lexus RX 350L

The Cadillac XT6 emerges as the RX's most direct rival since the RX 350L's primary competitors — that would be the Acura MDX and the Infiniti QX60 — are sitting on the bench for the 2021 model year. Both the Cadillac and the Lexus undercut European alternatives by thousands of dollars, providing strong value for the money. That said, the Lexus is even more well equipped, and the XT6 doesn't really offer anything to justify its higher price.

The Lincoln Aviator is more expensive than the RX 350L — especially once you start adding features to the Lincoln that are standard on the Lexus. But if you can swing the higher price tag, we think the Lincoln is the better buy. Its standard turbocharged V6 is significantly more powerful than the RX motor, the infotainment system is easier to use, and to our eyes, the interior design is more elegant. Lincoln has been on a roll recently, and its prowess shines through in the Aviator.

The Audi Q7 is our favorite SUV in the class, and though it's a bit pricier than the RX 350L, it's actually more affordable and practical than other like-minded European crossovers. The Q7 scores high marks for its stylish cabin, powerful V6, and wealth of exotic options. If you have wiggle room in your budget, the Q7 is undoubtedly the superior vehicle.
