Separated Twins - Jaguar XJ and Postwar Hudsons

My e-book on automobile styling argues that there hasn't been much evolution in the appearance of sedans since about 1950.  Yes, technology has improved in terms of metal stamping, autoglass forming, headlamp structure and other fields related to how cars look.  And there has been increased attention since the early 1980s regarding improved aerodynamic efficiency as a means of reducing fuel consumption.  But the dominant factor is fashion. Automobile styling fashions come, go, and occasionally return.

A case regarding the return of a style is the design of the 2010-vintage Jaguar XJ model.  It took me a while to make the connection, but it finally dawned on me that the XJ can be considered a modern version of the "step-down" Hudson of the 1948-1954 model years.

Let's take a look:


Here are the cars in profile, the XJ above, the Hudson below.  Both designs might be called "almost-fastback," where the top gradually curves downward and meets the lower body slightly in front of the back of the car.  Both designs use a "six-window" treatment, each door having a window plus a window placed to the rear of the rear door. (A "four-window" style has only door windows.)


And here are rear quarter views that offer more information on the treatment of the passenger compartment greenhouse.  Note the pinched, roughly triangular aft side windows on both designs as well as their relationship to the backlight windows.

True, there are differences in appearance. The XJ makes plenty of use of technological refinements and wind tunnel testing, but the most visible difference is that its rear wheels are exposed, whereas the Hudson's are skirted.  Nevertheless, the cars separated by the Atlantic Ocean and 60 years are conceptually similar in terms of basic shape.
