Playing a Blu-ray in the Suburban, both drop-down screens showed excellent definition. I found the remote control intuitive to use for selecting Blu-ray menu screens or switching video sources. However, when deployed these screens blocked the rearview mirror.
Making up for that loss of visibility were big side mirrors, a blind-spot monitor system, and a very good rearview camera with object detection. That rearview camera was essential in the Suburban, where the high back end and tinted rear glass compromised rear visibility. I was especially thankful for the cross-traffic alert system, which warned me when it sensed cars crossing the path behind me.
In a trick taken from Cadillac, the Suburban gets what GM calls its Safety Alert Seat. When the car wanted to warn me about traffic in my blind spot, stopped traffic ahead, or rear cross traffic, the seat buzzed on either or both sides. This butt buzz seemed kind of funny, but it definitely got my attention.
As a further aid to parking, an instrument cluster LCD showed distance lines to objects on all sides of the Suburban, data gathered from the vehicle's external sonar sensors. That LCD also showed me navigation, audio, phone, and trip information. When I hit the long highway and set the Suburban's adaptive cruise control, this display included my set speed and the following distance I had set for following traffic ahead.
In the center of the dashboard, the LTZ-trim Suburban came with an 8-inch touchscreen showing Chevy's MyLink infotainment system. I found MyLink's icon-based home screen very easy to navigate. I also liked the way that MyLink maintains icons for navigation, phone, and audio at the top of the map or stereo screen, giving instant access to each function. Another nice thing about Chevy's MyLink interface is that the company can add new icons for different functions easily, as there are multiple pages.
Bootup and response times for MyLink were a bit slow. I found this frustrating when I jumped in the Suburban, fired up the engine, and wanted to enter a destination. The lengthy boot time had me twiddling my thumbs, watching load screens and then the map slowly filling the screen.
I did like the look of the maps and appreciated the live traffic data. The system included dynamic routing to avoid serious traffic problems. Entering addresses was a bit tedious using the onscreen keyboard, but very easy with voice command, which interpreted a complete address string accurately.
There was no button for online destination search within the navigation app, but Chevy equipped the Suburban with the latest version of OnStar, which includes integration with the OnStar Remote Link app. With OnStar, I could have pushed the blue button on the rearview mirror to request a destination by business name, or used MapQuest on my home PC to come up with a route and send it to the car.
The MyLink interface made other apps easy to use, with large, intuitive menus for the hands-free phone system and stereo. I would have liked a screen showing all the available media sources for the stereo. Instead, I had to keep pushing a button below the touchscreen labeled Media, toggling through the various sources.
The stereo supports both HD Radio and satellite radio, and a big Pandora icon on the touchscreen showed that it would integrate with that app on my iPhone for Internet radio. You can also stream audio via Bluetooth, of course, and Chevy was extremely generous with the USB ports. There were two ports at the bottom of the stack, two more in the console, one hidden behind the motorized touchscreen, and another on the rear-seat entertainment system controls. As passengers will be relying on USB ports to keep their personal electronics charged, this profusion is very welcome.
I could easily browse music on a drive or my iPhone when plugged into a USB port, or use voice command to request specific music. However, when playing music over Bluetooth, MyLink only offered controls for skipping or pausing, with no music library browsing.
If Chevy had gone to unibody construction for the 2015 Suburban, it could have shaved weight to get better fuel economy, similar to what Ford and Dodge have done. Likewise, losing the solid axle in favor of an independent rear suspension would open up some more cargo area.
However, the boxy body design seems like a sign that Chevy wants to keep the Suburban closer to its roots. The vehicle has a long history and there are certainly buyers who will appreciate the solidity of body-on-frame architecture.
And, at least in LTZ trim, Chevy uses technology to overcome some of the issues of this style of construction. The Magnetic Ride Control is particularly good, proven for sport cars and now giving the big Suburban a more pliable ride. The new V-8, with direct injection and cylinder deactivation, does what it can for fuel economy. I have to wonder if an eight-speed transmission might have helped the Suburban achieve even better highway fuel economy.
The driver assistance technologies Chevy offers definitely help to make the Suburban safer and more drivable in urban environments. And with the MyLink infotainment system and profusion of USB ports, Chevy gives the Suburban a modern edge. It will certainly satisfy a host of younger passengers for long trips.
The fuel economy will be a sticking point for many buyers. I have to wonder if the Suburban will appeal more as a fleet and business vehicle rather than as a family SUV.
