Cadillac is stepping into the all-electric space with a wealth of new vehicles, including several new crossovers. The first of these was obviously the new Cadillac Lyriq, while the 2025 Cadillac Optiq and an as-of-yet unidentified three-row crossover are set to follow. Now, we’re taking a closer look at the 2025 Cadillac Optiq and forthcoming three-row crossover in the following visual size comparison.
Although GM has yet to release any official specs, both of these forthcoming all-electric Cadillac crossovers were recently spotted as camouflaged prototypes running side-by-side in a convoy, providing us with an opportunity to compare them, at least visually.
The first vehicle (that is, the prototype ahead and to the left in these photos) is the 2025 Cadillac Optiq. Originally expected to belong in the compact segment, a data sheet leaked by Chinese authorities reveals that the Optiq is in fact more of a midsize vehicle, as GM Authority covered previously. The wheelbase is 116.3 inches long, the overall length is 189.8 inches, the overall width is 75.3 inches, and the overall height is 64.7 inches.
Looking over these figures, the 2025 Cadillac Optiq is a bit larger than the ICE-powered Cadillac XT5, but smaller than the Cadillac Lyriq. So then – how does it shape up to the all-electric Cadillac three-row crossover seen on the right?
Well, for starters, this new three-row crossover is expected to be roughly equivalent to the ICE-powered Cadillac XT6 in terms of exterior dimensions. For reference, the XT6 is 198.5 inches long, 77.3 inches wide, and 69.9 inches tall. Next to the 2025 Cadillac Optiq, we also spot a shorter dash-to-axle ratio, a longer rear overhang, and a more upright rear section, the latter of which will likely provide considerably more cargo room than what will be offered in the 2025 Cadillac Optiq.
To note, the upcoming XT6-sized Cadillac three-row all-electric crossover may be called the Vistiq, the Lumistiq, or the Ascendiq, per Cadillac’s latest all-electric naming conventions.
