While the 2024 Chevrolet Silverado EV was by far the showstopper at GM's CES virtual Press conference this year, the auto giant's luxury arm Cadillac had something just as spectacular to showcase.

Enter the Innerspace. A futuristic low-slung concept coupe that is part of Caddy’s Halo lineup, which are a range of frankly over-the-top concept cars.

The Innerspace comes exactly a year after GM showed off the Personal space, an electric flying car, and Socialspace, a boxy-looking taxi at last year's CES. The main theme across the board is zero-emission autonomous technologies.

So what exactly is Innerspace? Well, the name should give it away. This otherworldly coupe’s focus is predominantly on providing its occupants the ability to ride in absolute comfort, as the world whizzes by. Since the Innerspace is a completely autonomous vehicle, you don’t have traditional controls like a steering or pedals.

Instead, you have giant screens and a sofa to create a lounge-like experience for its occupants. So in essence, you don’t drive, but ride on the interspace to your destination and engage with those wrap-around LED displays that can switch between augmented reality, entertainment, or wellness recovery. The Ultifi OTA software updates will allow both GM and third parties to offer custom experiences and additional themes. Purpose-built Goodyear tires, designed to mitigate soundwave resonance employ soybean oil, rice husk-based silica in their construction.

According to Cadillac, the Ultium batteries are scattered across the vehicle, rather than being concentrated in a single space. This may add complexity, but it also adds versatility giving engineers and designers more room to work with to create this rather magnificent experience. As a consequence, you have a form factor that is low, just like you'd find on a sports car.

As far as the design of this concept car is concerned, it couldn’t get more outlandish, could it? The Innerspace has the proper ingredients of a true concept car and looks like it's going a million miles an hour even when it's sitting still. Apart from the backlit front Cadillac front facia, the rest of the vehicle is unlike anything else you’ve probably seen before.

The proportions might suggest that this lounge on wheels can accommodate four, but uh uh. This is a strict two-seater only. Getting in and out of the vehicle will surely be a breeze thanks to that panoramic-glass bubble roof that pivots forward and rises up, apart from the doors that swing-out.

Now, who wouldn’t want concept cars to go into production, as is? Don’t get me wrong, it has happened in the past, but with these Halo concepts from Cadillac, these vehicles look like they’re decades out in the future. Having said that, while I don’t see the Innerspace going into production anytime soon, the tech that's on it just might make it to future cars within this coming decade.

Remember, concept cars are mainly a design exercise to show us what a brand is capable of delivering and the Innerspace certainly fits that bill rather well. We’ve also seen similar concepts from the likes of Audi Grand Sphere and the BMW Urbanaut recently, but those cars still allow for some level of driver input to control the vehicle. On a personal note, one of my favorite Cadillac concepts of modern times was the 2003 Cadillac Sixteen Coupe. So what do you make of the Cadillac Innerspace concept?
