Automotive heads up shows (HUDs) have been round way back to 1988, and whereas they’ve gotten brighter and extra colourful over time, even at the moment’s most subtle implementations nonetheless really feel a bit primitive. However after seeing what Hyundai Mobis (which makes auto elements for Hyundai, Kia and Genesis) is looking the world’s first full-windshield holographic show at CES 2025, it felt like I used to be taking a look at a serious evolution in-car infotainment.
Not like conventional reflective HUDs, Hyundai Mobis’ holographic windshield show (HWD) consists of two foremost elements: a projector (or on this case a number of projectors) hidden beneath the sprint and a particular optical movie with a rigorously tuned wavelength sensitivity embedded contained in the windshield itself. This mixture permits the HWD to pump out brighter and extra colourful pictures with a lot shallower viewing angles. Except you’re sitting in the suitable spot, it’s possible you’ll not even see the HUD in any respect.
On the Hyundai Mobis Kia EV9 demo car, the HWD isn’t restricted to only a small nook on the backside of the windshield. As an alternative, it’s cut up up into three totally different zones that span your complete width of the automotive: two for the motive force and one devoted to the passenger. For the motive force, the HWD can show fundamental stuff just like the automotive’s pace, instructions and extra. However the place issues get fascinating is when it exhibits holographic 3D maps that may regulate in real-time based mostly in your place, including a completely new dimension that can assist you attain your vacation spot.
For passengers, their devoted part of the HWD can be utilized independently for checking car data or just watching a video or enjoying video games. Critically, due to the restricted viewing angles of Hyundai Mobis’ tech, the motive force can’t see the passenger’s aspect of the HWD, so there’s no distraction threat. The entire system is reasonably spectacular, as a result of a lot of the tech is hidden beneath the dashboard. The one proof that this HWD is totally different from extra conventional implementations is that should you look actually carefully on the windshield when it’s off, you possibly can see a faint define the place the optical movie is sandwiched between the glass.

After trying out Hyundai Mobis’ demo, I additionally acquired an opportunity to speak to one of many engineers behind the HWD, Dr. Minho Shin, who added extra context and perception in regards to the tech. By way of a translator, Dr. Shin advised me that the corporate envisions its HWD as a strategy to increase the principle show present in most trendy automobiles, which is able to more than likely function the principle management heart for manipulating what you see on the windshield. And for passengers, it’s attainable they’ll be capable to management what they see on their aspect of the HWD just by casting content material from their telephones. Moreover, the location and measurement of the holographic show makes it simpler for the motive force to see and work together with useful instruments like real-time 3D maps in comparison with present tech. Dr. Shin even stated that it’s attainable to create a model of the HWD that may cowl each your complete width and vertical top of the windshield, which looks like one thing straight out of each sci-fi or cyberpunk film ever made. Nevertheless, as a result of legal guidelines in lots of nations, that sort of performance isn’t broadly permitted.
Now it have to be talked about that at CES 2025, BMW demoed related expertise with its Panoramic iDrive system. The Bavarian automaker’s method is arguably a bit additional alongside, not less than on the subject of being built-in into its current infotainment system and its availability, which is slated to reach on all new fashions by the tip of 2025. Nevertheless, once you look nearer, it virtually looks like BMW is dishonest a bit through the use of a black movie that goes alongside the underside of the windshield as a substitute of being fully clear like with the HWD, which can give Hyundai Mobi’s tech considerably improved driver visibility and consciousness.
Whereas BMW’s panoramic HUD is slated to reach first, Hyundai Mobis gained’t be far behind as the corporate hopes to place its HWD into manufacturing by someday in 2027.
