The current Dodge DIPLOMAT is 205.1″ long, 73.2″ wide, on a 112.6″ wheelbase, weighing 3,635 lb. At 17.1 feet it fits a standard garage and overhangs a street parking space.
Every Dodge DIPLOMAT generation, measured
One row per generation. Watch the weight column — that is where most of the change happens, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.
| Generation | Length | Width | Height | Wheelbase | Curb weight |
|---|---|---|---|---|---|
| 1977–1989 | 205.1″ | 73.2″ | 54.3″ | 112.6″ | 3,635 lb |
DIPLOMAT year by year
Measured every model year, not just at generation changes — 13 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.

| 1989 | 204.7″ | 72.4″ | 112.6″ | 1 | |

Will a DIPLOMAT fit
The practical question behind every dimensions search. A single-car garage in the US is typically 20 feet deep; a street parking space is about 18. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 17.1 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 17.1 ft | Overhangs — expect a tight squeeze |
| Standard parking bay width | 8.5 ft wide | 6.1 ft | Room to open doors both sides |
Against cars of the same length
Compared with 512 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 | 73.2″ | 75.2″ | -2.0″ |
| Wheelbase | 112.6″ | 118.1″ | -5.5″ |
| Curb weight | 3,635 lb | 4,374 lb | -739 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. Lighter than typical for its size generally means better fuel economy and shorter stopping distances.

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.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and a table of forty near-identical rows helps nobody. Where a generation offered several body styles, the figures are the base measurements for that generation.
