Consumer Reviews for the Cadillac XT6
Read recent reviews for the Cadillac XT6
GREAT SUV!
Xt6 lover. , 12/27/2020
2021 Cadillac XT6 Premium Luxury 4dr SUV AWD (3.6L 6cyl 9A)
This truck is great. Super quiet, comfortable and roomy. I’m 6’3”, and have plenty of leg and head room. Second row easily fits bulky rear facing car seats without compromising front seat leg room. Door openings are huge and open all the way, so getting in and out is easy, and getting car seats in/out is easy. Seats are big and comfortable, the ride is very smooth, and very quiet. V6 … motor has plenty of power. Infotainment system is great. Modern, but simple to use. Similar to bmw idrive, but I find it easier to use. Wireless Apple CarPlay is awesome, and works flawlessly. We shopped x5, q7, gle, xc90, and mdx. Cadillac is the clear winner if you value comfort, and space. We originally were gonna get another bmw, an x5, but after driving the xt6, it was no contest. The cadillacs overall ride and the room won us over. Interior material quality is great too, I read a lot of car website reviews saying otherwise, but they are totally wrong. If you want a luxury suv that puts the most value on comfort, space, quietness, and a smooth ride- this is the suv to get. The v6 motor is great too, it’s very smooth and has plenty of power.
