A Luxurious Escape from Flagstaff to Phoenix in the Mercedes-Benz GLS SUV
There’s nothing quite like a summer road trip through Arizona, where the elevation drops, the cacti rise, and the heat kicks in with unapologetic intensity.
The drive from Flagstaff to Phoenix is a two-hour descent from 7,000 feet to under 1,100, a stark climate shift that can make the journey feel less like a road trip and more like a survival test—unless you’re behind the wheel of something built for comfort, power, and poise. Enter the 2025 Mercedes-Benz GLS SUV from Mercedes-Benz of Northern Arizona, a full-size luxury SUV designed to transform a hot, hectic desert haul into a relaxed, high-end experience.
Why the Summer Drive to Phoenix Can Be Brutal
Summertime in Arizona can be stunningly beautiful—but also brutally hot. While Flagstaff offers cool pine breezes and daytime highs in the 70s and 80s, Phoenix regularly roasts at 110°F and higher by mid-afternoon. This means your car isn’t just a vehicle; it’s a climate-controlled lifeline. Without adequate ventilation, space, and suspension, a road trip like this can become uncomfortable quickly.

Add to that the dry heat that wears on your skin and sinuses, congested summer highway traffic, and the descent through winding high desert passes, and it’s clear: not just any vehicle will do. You need more than just wheels. You need a sanctuary on the move.
Meet the 2025 Mercedes-Benz GLS: Elegance Meets Capability
The GLS SUV is Mercedes-Benz’s flagship luxury SUV, and it lives up to its billing with a combination of off-road capability, high-end tech, and full-size comfort that make it ideal for any Arizona adventure. Its intelligent 4MATIC® all-wheel-drive system gives you confidence in varying terrain, whether you’re weaving through Flagstaff’s alpine roads or gliding down I-17’s sweeping curves toward the Valley.
Inside, the GLS feels more like a five-star hotel than an SUV. With seating for up to seven, ventilated and massaging seats, and five-zone climate control, everyone stays cool and comfortable—even when the landscape outside looks like a scene from Mad Max.

Let’s Talk Tech, Because the Desert Demands It
The GLS comes standard with Mercedes-Benz’s MBUX infotainment system, which includes voice control (“Hey, Mercedes”), Apple CarPlay®, Android Auto, and twin 12.3-inch displays. It’s perfect for navigating traffic, managing playlists, or asking for directions to that off-the-beaten-path taco shop near Black Canyon City.
More importantly, the optional E-ACTIVE BODY CONTROL system scans the road and adjusts the suspension in real-time. That means less bouncing on potholes, smoother transitions through mountain passes, and almost no body roll even when descending winding canyon roads. Translation? No Dramamine required.
And when the heat really hits? GLS offers pre-entry climate control, letting you cool the cabin before you even open the door. Essential when you’re heading back into your SUV after a photo op in the 115°F desert sun.
Scenic Stops That Are Even Better in the GLS
Yes, the GLS is designed for refined highway cruising. But what makes it truly exceptional is that it can handle a little off-grid adventure, too. If you’re heading to Phoenix and have time to spare, these detours are where the GLS truly shines—offering luxury comfort in rugged landscapes.
Sedona’s Red Rock Country
About 45 minutes off I-17, Sedona is more than just a postcard-perfect town—it’s a spiritual and geological marvel. Nestled among towering red sandstone formations, Sedona is a hub for hiking, photography, and those seeking a little metaphysical refresh. And if you’re in the 2025 Mercedes-Benz GLS, getting there is half the fun.
While many SUVs might struggle on the switchbacks that lead into Oak Creek Canyon, the GLS’s adaptive suspension and powerful twin-turbo engine eat up every curve and incline. The E-ACTIVE BODY CONTROL means the GLS adjusts with the terrain, and the optional Off-Road Engineering Package adds underbody protection and additional drive modes—ideal for reaching more secluded trailheads like Schnebly Hill Road or Red Rock Crossing.
Inside, you’re shielded from the summer heat by high-performance sun-reflecting glass and ventilated seats. When you arrive, you’ll be relaxed and ready for a hike—or maybe just a quiet moment by the creek. As you leave Sedona and descend back toward the highway, you’ll appreciate the smooth ride and commanding visibility that makes the GLS SUV not just capable but composed.
Montezuma Castle National Monument
Just off I-17 near Camp Verde, Montezuma Castle offers an unexpected glimpse into the past. This cliffside dwelling was built over 600 years ago by the Sinagua people and stands remarkably preserved in the arid desert. It’s one of the easiest and most fascinating stops on the drive to Phoenix—and even more enjoyable when you’re traveling in the comfort of a Mercedes-Benz GLS.
The access road can be rough in places, especially in summer when heat and monsoon weather wreak havoc on pavement. But the GLS, with its high ground clearance and advanced 4MATIC® all-wheel-drive, makes short work of any washboard road or loose gravel. This is where features like hill descent control and off-road drive modes come into play, ensuring your vehicle stays stable while you explore the area’s rugged terrain.
Montezuma Castle itself is a short, shaded walk from the parking area, ideal for stretching your legs without baking in the Arizona sun. The SUV’s massive panoramic sunroof lets you continue enjoying the view even after you’re back in your plush, air-conditioned cabin—whether you’re headed deeper into the Verde Valley or back on the road toward Phoenix.
Tonto National Forest Detour
As you descend closer to Phoenix, you’ll pass near Tonto National Forest—one of the largest and most ecologically diverse forests in the United States. This area offers an opportunity to explore high desert vistas, cactus-covered hills, and winding backroads. It’s also where the GLS SUV proves it’s more than just a luxury family hauler—it’s a real off-road machine when needed.
Tonto’s terrain can range from sandy washes to rocky trails. The GLS’s Off-Road+ mode adjusts the throttle, suspension, and traction control for the best performance on difficult terrain. The AIRMATIC® suspension can even raise the vehicle to improve clearance. And with Dynamic Select, you can easily switch back to Comfort mode when you’re ready to glide back onto smooth pavement.
If you’re towing a trailer or boat to one of Tonto’s lakes, the GLS also boasts a 7,700-lb towing capacity—so bring the toys. Whether you’re stopping for a photo of Roosevelt Lake, taking a dusty detour up Forest Road 60, or just pulling over for a scenic picnic, the GLS from Mercedes-Benz of Northern Arizona makes it not just possible—but enjoyable.
