FactAdler officially pulled the Diplomat from sale in 1939 — but kept quietly building a few more in 1939 and 1940, likely for the military or export.
The Adler Diplomat, introduced March 1934 (3,205 built to 1940) as a direct replacement for the Standard 6 (and, less directly, the eight-cylinder Standard 8), was a substantial six-cylinder "limousine" saloon from the Frankfurt maker. Its 2,916 cc straight-six side-valve engine initially claimed 60 PS (59 hp), later reworked with a light-alloy cylinder head and higher compression to 65 PS (64 hp). Front engine, rear-wheel drive, manual with lockable freewheel; wheelbase 3,200 mm (130 in, four-seater) or 3,350 mm (132 in, six-seater), length 4,750-5,050 mm (187.0-198.8 in) depending on year and body, width 1,740 mm (68.5 in), height 1,650 mm (65.0 in).

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.
