What you’ll notice first about the Cadillac XTS4 is that it’s a mix of sleek and tech combined into one. From the sparkly paint finish outside to the lush leather interior, you’ll know you’re in a car that starts around $45,000 and aims to compete with the other mid-size luxury vehicles in its class. And once you get inside, you’re fairly much forced to notice the vehicle’s CUE electronic command center, but if you focus on that as the “tech,” you’ll miss the bigger picture. Throughout the vehicle are little details to make life easier. A map floats in the little area by the speedometer (plus three other pieces of data—pick what you want from a menu). There’s all kinds of “you’re about to smack this thing” protections built in (like vibrating thingies in the seat that buzz your butt if they want you to look around). There’s a heads-up display so you can see things in the windshield (I tried to capture that below). The side mirrors have little lights that tell me if someone’s in the blind spot, too. The car is filled with these types of ways to save one. A quick digression about the CUE system: it’s the big central system that controls audio, temperature, GPS, and phone (and other stuffs). I think because we all use smartphones these days, the responsiveness of the CUE system just doesn’t feel iPhone-like. That’s my only knock on the car. The CUE command module didn’t feel as responsive as I’d have wanted. Beyond that? This car tells you when someone’s in your blind spot. It helps you back up. It lets you not smash up all over the curbs. It has two or so USB ports and Bluetooth to let you play your music in the car. It, of course, has OnStar and all those goodies. There’s a lot to like. And it looks nice! People are saying that this is the best kept secret at Cadillac, because the ATS model is getting all the accolades. But the question remains: will Cadillac be able to acquire the 40-something car buyer and fend off the European and Asian luxury car dominance? We think it’s possible. This post was not a sponsored post, but GM sent us the Cadillac to play with for a week. They had no say in how we reported on the car, and didn’t ask for anything specific. Yes, we gave the car back after a week.
