The Fiat 510 was built between 1920 and 1925 (around 14,000 produced) in 4-door sedan and cabriolet bodies, of similar design to the smaller 501 and 505, with a 3446 cc sidevalve straight-six of 46 hp and a 4-speed manual, wheelbase 340 cm (133.9 in) and curb weight 1,550 kg (3,417 lb); it followed the Tipo 7 and preceded the 512.

The sporting 510 S shared its 3.4-litre six with the ordinary 510, just tuned harder and set in a shorter chassis — across the whole 510 line, only around 14,000 cars were ever built.

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.
