With advanced styling and features combined with more affordable pricing, Cadillac rocketed up the sales charts in 1941.

Series Sixty-One Five-Passenger Coupe 

It’s fun, but the study of automotive history can be a complicated exercise. Some Motor City trends and events could remain mysteries forever. However, the reasons for the success of the Cadillac division of General Motors in 1941 are easy to identify. That year, Cadillac made all the right moves with advanced styling, attractive pricing, and the first fully automatic transmission on the market. GM’s Hydra-Matic.

Series Sixty-One Five-Passenger Touring Sedan

First, the LaSalle companion brand was eliminated and replaced with a new low-priced Cadillac, the Series Sixty-One. Available in two body styles, a dramatically styled streamlined coupe and an equally daring streamlined sedan, the Sixty-One was priced right, too, at $1,345 to $1,535. With its premium appointments, this new car was a Cadillac in every way, including the name. Cadillac had effectively moved down market, but it wasn’t perceived that way by buyers. They snapped up more than 29,000 Sixty-Ones, exceeding LaSalle’s sales in the previous three years while also contributing 44 percent of Cadillac’s total volume in 1941

Series Sixty-Two Convertible Coupe 

Cadillac’s Series Sixty-Two, the next step up in the product line, enjoyed similar success in ’41. It featured the same forward-looking styling as the Sixty-One, with a wide horizontal grille and elements borrowed from Bill Mitchell’s stunning Sixty Special introduced in 1938. The five Torpedo body styles included a coupe and sedan in standard or De Luxe trim, along with a convertible sedan and the popular convertible coupe (above), which sold 3,100 copies. Total volume for the Series Sixty-Two came to nearly 25,000 cars, so together the Sixty-One and Sixty-Two generated 80 percent of the division’s business that year.

For 1941, Cadillac discontinued the costly, low-volume V16 to focus entirely on the 346 cubic-inch L-head V8, the only engine available across the Cadillac product lines that year. With a 7.25:1 compression ratio and a two-barrel carburetor, it was rated at 150 hp, and with hydraulic valve lifters and a counterbalanced, harmonically balanced crankshaft, it was smooth and silent.

But the major development was GM’s Hydra-Matic Drive, the industry’s first fully automatic transmission. Introduced at Oldsmobile the year before, it was now available as a $125 option on all Cadillacs. Thirty percent of Cadillac buyers in ’41 opted for Hydra-Matic, a remarkable take rate for such a new and unfamiliar feature that no doubt added to the climbing sales figures.

1941 Cadillac Duchess 

Led by Cadillac general manager Nick Dreystadt, the division was clearly moving away from the traditional big Cadillacs of years past. And it was paying off in increased volume, as sales rocketed up to more than 66,000 cars in 1941, its biggest year to date. The Series Sixty-Three and glamorous Sixty Special sold respectably, but the grand Sixty-Seven and Seventy-Five moved in very small numbers.

Still, grand they were, and the grandest Cadillac of all in ’41 was the Duchess (above). Built on a Series Seventy-Five 136-in wheelbase chassis with unique custom bodywork, it was created especially for the Duke and Duchess of York on the orders of GM chairman Alfred P. Sloan, under the direction of styling boss Harley Earl. Today the Duchess resides in a Canadian collection.
