Video: 2017 BMW 7 Series: Tech Features Review

In the new 740E plug-in hybrid, its high tech drive train is complimented by high-tech convenience features like gesture control, a key fob with an integrated screen and a 3D camera view. We put these features to the test and found out sometimes, the latest isn't the greatest. The 7 Series has the latest version of BMW's iDrive system, and you can operate the multimedia system either with the knob on the console or with the dashboard touchscreen or with gesture controls. There's a camera in the headliner that recognizes certain gestures. When you have an incoming call, you can accept it by pointing at the screen or swiping to the right to decline it. You can also raise or lower the audio volume by rotating your finger in a circular motion, right or left. And finally, you can customize what the system does when you make the peace sign. Once you've had time with gesture controls, some of them work reasonably well, others, not so much, but overall, the system doesn't really make your life in the car any easier because in the case of adjusting the volume, there are already easy to use controls on the steering wheel and the dashboard. And while the system might impress your friends the first time you show it to 'em, it's not a feature I'm going to be using day in and day out. While backup cameras are commonplace and 360 degree camera systems are offered on many cars, BMW has taken the feature a step further with its 3D view that's part of its optional 360 degree camera system. The setup uses images from the four external cameras to create a virtual view of what's around your car on the dashboard screen. And you can spin it using the iDrive controller or through gestures. It's a very cool and unique effect, but the systems other views are more practical for maneuvering in tight spaces. Key fobs have largely been left behind as technology and cars has zoomed ahead, but BMW has modernized the key fob with its new display key. It's standard on the 2017 7 Series and has an LCD screen that shows estimated range as well as fuel and charge levels. Even cooler, when you get the remote control parking system that's available for gas-only 7 Series models, you can move the car into a tight parking space when standing outside using just the key. Some cars are defined by their features, but that's less the case with the 7 Series which gets its kudos because it drives great and has a truly luxurious interior. These tech features add some flash, but they come up short on function.
