| Generation | Length | Width | Height | Wheelbase | Curb weight |

Will a Optiq fit
The practical question behind every dimensions search, and for a 15.8-foot Cadillac Optiq it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the Optiq clears the garage by 3.2 ft. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 15.8 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 15.8 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 6.3 ft | Room to open doors both sides |
Against cars of the same length
Compared with 981 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.
| Measure | This car | Typical car of this length | Difference |
|---|---|---|---|
| Width | 75.2″ | 72.8″ | +2.4″ |
| Wheelbase | 116.1″ | 110.2″ | +5.9″ |
| Curb weight | 5,203 lb | 3,849 lb | 1,354 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. At 5,203 lb the Cadillac Optiq is 1,354 lb heavier than typical for its size, which generally shows up as fuel economy and stopping distance.

How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 2 measured model years for the Cadillac Optiq between 2025 and 2026.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Cadillac Optiq fits into 1 rows instead of 2. Where a generation offered several body styles, the figures are the base measurements for that generation of the Cadillac Optiq.
