Both the Cadillac Series 70 and Series 75 were Cadillac's full-size V8-powered vehicles for over twenty years.
The Series 70 replaced the 1935 335-D as Cadillac's mainstream vehicle. Introduced at the same time, the Series 60 was available as a much less expensive vehicle. The Series 80 was almost identical to the Series 70, but rather than using the new Monobloc V8 engine, it came with Cadillac's V12.
Eventually the short wheelbase Series 70 was replaced by the Series 62 in 1941. Meanwhile, the long wheelbase 75 series became part of the Fleetwood line.
With a 135 hp (101 kW) engine that was both more powerful and less expensive, the Series 70 should have been an instant hit with the public. Unfortunately even the with the stylish body by Fleetwood wasn't enough to compare with the exorbitant price of $2,500 and up during the depression era.
In 1936, only 5,248 were sold.
Available in three basic models that shared the same engine and 3-speed transmission, the series 70 was available in 36-70, 36-75 and 36-75 Commercial. In 1937 minor body style changes were made. The 36-70 came with a 131 inch wheelbase and reached an overall length of 206.25. The 36-75 reached 213.5 in length and had a 138 inch wheelbase. The 36-75 Commercial model came with 156 inches in wheelbase, and also reached 213.5 in overall length.
For the 1942 model year, the Series lineup remained the same as in 1941. Front fenders on all models except the Series 75 became extended into the front doors.
As the grille became more massive it included round parking lights and rectangular fog light sockets, and had fewer bars. Series 75 had the new grille in 1942, but retained the 1941 fender treatment. The 75's received a rounded nose on the hood louvers as a detail trim change.
Though they adopted the new 1942 front-end styling, the 75's retained the 1941's short, square fenders and triple chrome strips behind the wheels. These same square-rigged lines continued through 1949.
In 1941, Fleetwood had two designated series, the Fleetwood Sixty Special and the Fleetwood Seventy-Five sedans. The Sixty special was built on 126-inch chassis and was more of a luxurious vehicle for those who strived for appearances and distinction.
The Seventy-Five sedans were built on a 136-inch wheelbase, and had seating room for five, seven or nine passengers. The 75 Sedan came with an option of the electrically powered glass ‘Imperial Division'. It was also available on a 1630inch wheelbase commercial chassis.
The most expensive Seventy-Five Formal sedan which seated seven was available at $4,045.
Installed with Cadillac's 368 in³ V12 engine, the Series 80 was produced for 1936 and 1937 only and was simply a model 70 or 75 with an updated engine. The Series 80 had an output of 150 hp (112 kW).
After the war, the Series 75 returned as Cadillac's largest model. Keeping the same 346 in³ L-head V8 as other Cadillac's that year, it retained most of the pre-war styling and rode on the long 136 inch wheelbase.
In 1949, the new Cadillac OHV V8 was introduced with only minor trim differences and a 331 in³ engine that produced 160 hp (119 kW)
The following year an all-new Series 75 was introduced and would replace the final pre-war design at Cadillac. This new model offered 7-passenger seating via jump seats, achieved a new 146.75 in wheelbase and had an engine output of 190 hp (142 kW).
In 1954 the wheelbase had moved up to 149.8 and had reached an engine output of 230 hp (172 kW). The following year the engine output jumped to 250 hp.
The series 75 reached a production number of 1527.
The 5 passenger touring sedan was longer and heavier than the 60 series car, which gives the car a sleek elegant look. The Cadillac 75 series was an ideal tour or parade car.
The Cadillac Imperial Business Sedan was a nine passenger sedan introduced in 1947. Only 80 of these vehicles were produced that year.By Jessica Donaldson
