FactThis Series 70 arrived right as Oldsmobile debuted the Hydramatic — the industry’s first fully clutchless automatic transmission.
The Oldsmobile Series 70 was a full-size midrange automobile produced between the 1939 and 1950 model years on the GM B-body (designer Harley Earl), sharing its platform with the Cadillac Series 61, LaSalle Series 50 and Buick Century and Special; the Series 70 was powered by a straight-six or straight-eight, replaced the Series L, and was named Dynamic in 1940 when the Series 60, 70 and 90 were called the Special, Dynamic and Custom Cruiser. The 1939–40 cars had a 120 in wheelbase (length 197.0 in in 1939 and 199.8 in in 1940) with 215 or 230 cu in Oldsmobile straight-six engines and a business coupe, club coupe, four-door sedan and two-door convertible; the Hydramatic, a fully clutchless automatic, debuted in October 1939 for 1940 Oldsmobiles.

Photographs
Oldsmobile's 1950 Seventy-Six Holiday hardtop — a steel roof welded onto the convertible body — was the only time the brand ever paired its upscale hardtop styling with a plain six-cylinder engine, and barely 538 were sold.
To mark the company's 44th anniversary, Oldsmobile's limited-production 1942 cars — including the Dynamic Cruiser — wore a tiny "B-44" badge on the grille.

Rivals
Same body, same money, other badges — tap any card to flip.
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.
