FactAustin's flagship limousine was no hot rod: a 1953 road test of the Princess Long-Wheelbase by The Motor clocked 0-60 mph in a leisurely 23.3 seconds.
The Austin A135 Princess Long Wheelbase Saloon (DS6, 88 built) and Limousine (DM4, 3,238 built, plus 18 landaulettes) were introduced in 1952 with the D-Series 3991 cc six-cylinder engine on a 132 in wheelbase. The GM Hydramatic 4-speed automatic and Hydrosteer power steering from the Princess IV were options from 1956. The marque name changed from Austin to Princess in August 1957 and to Vanden Plas from July 1960, and the long-wheelbase models continued to be built by hand in limited numbers as the Vanden Plas Princess 4-litre Limousine until 1968, when the Jaguar Mark X-based Daimler DS420, initially produced at the Vanden Plas works in Kingsbury, replaced them. The limousine was luxuriously appointed with polished wood, optional mohair rugs and a radio with controls in the armrest, and among the long list of extras were monograms and a flagstaff.

Austin priced the flagship Princess IV at 6.5 times an Austin A30 — so far above the market that almost nobody bought one.

Austin's flagship limousine was no hot rod: a 1953 road test of the Princess Long-Wheelbase by The Motor clocked 0-60 mph in a leisurely 23.3 seconds.
Several early Princess saloons got an unglamorous second act: converted into taxis in the late 1950s and fitted with Perkins diesel engines to save on fuel.

It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.

Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.

A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.

The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.

The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.

The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.

The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.

This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
