Buick enjoyed a record year in 1941 with strong sales, an extensive model line, new features, and the slogan “Best Buick yet!”

Buick has certainly had some memorable slogans over the years, from “When better automobiles are built, Buick will build them” to “Wouldn’t you really rather have a Buick?” For 1941, the message was simply “Best Buick yet!” Now there’s a phrase filled with confidence, and in this case it was justified. Under the leadership of division president Harlow Curtice, Buick enjoyed its best selling year in history with more than 377,000 cars delivered. That was a 34 percent increase over the previous year and second only to giant Chevrolet among the General Motors divisions. Let’s take a look at what generated all that success.

After the unfortunate “short frame” debacle of 1939 (see our feature here) Buick quickly went straight back to conventional X-braced, ladder frame construction, and that’s what we find on the ’41 models. While there were five different wheelbases (118,121, 126, 128, and 139 inches), all were of the same general configuration, with short/long-arm IFS at the front and a torque tube and coil springs at the rear. This rear suspension system, used by Buick for decades, enabled soft rear spring rates that contributed to the plush and quiet ride the division was known for.

Another familiar Buick feature was the smooth, powerful straight-eight engine with overhead valves (“Valve-in-Head” in Buick lingo). Offered in two displacements for ’41, 248 cubic inches and 320 cubic inches, the eights provided up to 165 hp—15 hp more than the Cadillac V8 at the time. One new wrinkle for ’41 was Compound Carburetion, with two two-barrel carbs (Carter or Stromberg) spread out on the inline eight’s long intake manifold to improve fuel distribution. Essentially, the setup worked like the four-barrel carburetors that would come along some years later, with the front carb handling the low-speed duties and the rear carb kicking in when the throttle was tipped.
Roadmaster Series 70 Touring Sedan
As you’ve no doubt already gathered from the five available wheelbase lengths, the Buick model line for ’41 was an extensive one. The 40A Series Special was a price leader built on a 118-in wheelbase chassis and Chevrolet body shell, selling for as low as $915. The 40B Series Special and Series 50 Super shared the 121-in chassis, while the Series 60 Century rolled on the 126-in platform, the Series 70 Roadmaster 128 inches. The long-wheelbase 139-inch chassis was reserved for the Series 90 Limited, most often bodied as a formal sedans or limousine. There were coachbuilt versions, too, bodied by Brunn.
Special Series 40B Sedanet
However, the star of the show in ’41 was the Series 40B Special in GM’s new streamlined coupe body style, which Buick called a Sedanet. (The name was then popularly applied to the other GM streamliners, often spelled as sedanette.) Daring and modern for its time, the Special Sedanet sold 88,000 units, second only to the Special four-door Sedan. The standard 40B Specials outsold the junior-sized 40A Specials by a large margin, but all told, Specials accounted for 63 percent of the division’s sales in ’41.
While it sold in far smaller numbers, the 90 Series Limited was the flagship of the ’41 Buick line, pushing the division well into the middle of Cadillac territory (and surely vexing Cadillac management). With prices ranging from $915 to $2,350, Buick now had by far the broadest product line at GM, while as division manager, Curtice forged close relationships with chairman Alfred P. Sloan and styling chief Harley Earl. In 1953, he was appointed president of General Motors.

Cadillac seemingly took a step backward when they reverted to flathead engines in the latter half of the ’30s, while Buicks had consistently been OHV since the early ’30s. In 1941 the sibling rivalry between the two brands was exacerbated by not only Buick’s higher horsepower, but also the supposed availability of the custom bodied Buicks, unlike anything Cadillac offered that year, listed in the ’41 catalog, but in reality, not likely were any ever built. Given Buick’s experience with compound carburetion (standard on some models, and optional on others) in ’41 and ’42, it’s not surprising that the four barrel carburetor was later invented by a Buick engineer named Braun in the early 1950s.
If my readings from the days when I was a member of the national Buick club (was showing a 1937 Special two door sedan at the time) are still in memory, Buick was always overhead valve, going back to the first two(?) cylinder car.
George is entirely correct. I should have clarified that I spoke of Buick’s straight eights, vs. Cadillac’s V.
Thanks for all you do, Mac. It might be difficult to do on a daily basis but I’d love to see deeper dives on these wonderful articles. They are always so interesting and informative. And, as a person who greatly appreciates the gorgeous brochure art in the accompanying images (one of my favourite bookmarks is The Old Car Manual Project), links to larger images would enhance the experience for us all. Thanks again!
Do car makers still do slogans? I can’t remember any since Chevrolet had “The heartbeat of America”. Which did little to persuade me that their cars were stylish, fun or innovative. It only implied that I was a quisling for not buying an American car (possibly built in Canada, Mexico or imported from Japan).
Get Iacocca on the phone; this is right up his alley. Maybe that’s what ol’ Elon needs to get his ducks back in a row. I’m sure he can come up with something unique.
The Compound Carburetion, while effective, was hard to keep adjusted and, during World War II, many Buick owners disconnected the second carburetor in order to conserve fuel. The four-barrel carburetor was successfully developed for the 1952 models. (Even more remarkable, the 1941 slogan “Best Buick Yet” resurfaced 15 years later as the ad campaign for the 1956 models…)
What about the convertible model?
