Will a DIPLOMAT fit

The practical question behind every dimensions search, and for a 17.1-foot Dodge DIPLOMAT 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 DIPLOMAT clears the garage by 1.9 ft. We allow a foot of clearance in both — nobody parks to the millimetre.

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.

A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. At 3,635 lb the Dodge DIPLOMAT is 739 lb lighter 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, 13 measured model years for the Dodge DIPLOMAT between 1977 and 1989.

One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Dodge DIPLOMAT fits into 1 rows instead of 13. Where a generation offered several body styles, the figures are the base measurements for that generation of the Dodge DIPLOMAT.
