The Oldsmobile G-Series 70 was introduced in 1939 and would remain in production until the onset of World War II. The new G-Series had the previous L-Series chassis and powered by the smaller F-Series powerplant. The L-head, 230 cubic-inch unit offered 95 horsepower and 180 foot-pounds of torque. The wheelbase measured 120 inches and was 197-inches long. The bodystyles were similar to the L-Series cars and included a convertible, business coupe, club coupe, and 2- and 4-door sedan. Sales were strong, with most buyers purchasing the 4-door sedan (of which 38,145 units were sold).
For 1940, the Series 70 remained on a 120-inch platform and was powered by a 95 HP, six-cylinder motor. The five bodystyles were still available.
For 1941, the Series 70 Dynamic Cruiser was available as the 76 which used a stright-6 and the 78 which had a straight-8. The Model 78 was retired after the 1949 introduction of the new Oldsmobile 88, which was based on the Series 70. It also brought with it the new Rocket V8. The Model 76 remained in production until 1950. By Daniel Vaughan | Sep 2011
