The Cadillac V-12 was an exclusive V-12-powered luxury car manufactured by Cadillac from 1930 through 1937, below only the top-of-the-line V-16, powered by the 368 cu in (6.0 L) Cadillac V12 and furnished with similar custom Fisher and Fleetwood bodies in relatively small numbers: 10,903 in seven model years, the majority in the first; it was Cadillac's first, and to date only, standard production V-12 automobile. The V-12 was essentially a truncated V-16, designed by Owen Nacker, retaining the V-16's 4-inch stroke but bored out to 3.125 in from 3 in, with a 45-degree bank angle (less ideal than a 60-degree design) and overhead valves; it was less powerful than the V-16, generating 135 versus 175 horsepower. The 1931 Model 370A, introduced in October 1930 (a V-12 roadster paced the Indianapolis 500), had a 140 or 143 in wheelbase against the V-16's 148 in, a hood four inches shorter and smaller headlights and horns, and cost about $2,000 less per body style, starting at $3,795; it outsold the V-16 with 5,733 sold in 1931 against 363. The 1932 370B (a flared radiator shell, a stiffer frame, a Cuno oil filter and dual Detroit Lubricator carburetors) sold 1,740 in the Depression; the 1933 370C (V-shaped grille, skirts on the front and rear fenders and Fisher no-draft vent windows) sold 953; the 1934 370D was restyled on a completely new chassis with dual X-frame construction, "Knee-Action" front suspension and Hotchkiss steering, and the 1935 370E added the Fisher Turret Top and an increase in horsepower to 150 (only 1,098 sold over the two years). Dimensions: wheelbase 140.0 in (1931), 134.0 or 140.0 in (1932–33) and 146.0 in (1934–35); 209.0 in long in 1931 and 216.0 in in 1934–35; 73.6 in wide (77.0 in from 1932); 72.5, 71.5 and 69.5 in high; 5,200–6,200 lb.

This was Cadillac's only standard-production V-12 ever built — and by 1937 it was down to one model, selling just 478 before Cadillac killed it for good.

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.
