I guess the BT37, at least among F1 cars. (I think Brabham was still making and selling cars of lesser formulas, but I'm not sure.) The BT42 wasn't quite a finished product, but Murray took care of that in the BT44, and his cars were contenders for another decade.
The BT34 "Lobster Claw" from Ron Tauranac was succeeded by the BT37, designed by Ralph Bellamy, that raced during th 1972 season.
Ha ha, I thought this one would raise a few questions. He was a Swedish race driver who had a few races with Tyrell and ATS, and also a session drummer who played with ABBA https://www.historicracing.com/driverDetail.cfm?driverID=1392
Even Enzo felt that the T4 was ugly, but it got the job done. Its successor, the T5, was a bit less ugly but was much worse on the track. Of course, it had little development because Ferrari was concentrating on the turbo engine for 1981.

Jacques Laffite turns 81 today. I took this photo of Jacques in the Ligier JS11/15 coming out of Casino Square at the 1980 Monaco Grand Prix. Jacques finished 2nd. That location, with the Hotel de Paris as a backdrop and a slight elevation change, was my favorite place to photograph at Monaco. Guy Ligier named all of his cars starting with JS, the initials of his friend Jo Schlesser who died in the 1968 French Grand Prix. The distinctive blue/white Gitanes livery was among my favorites of that era. Image Unavailable, Please Login
Actually the Ligier was also the fastest car at the start of the 1979 season. Laffite and Depailler qualified first and second in the first 2 races, and started first and second in 4 out of the first 6 races.
Gerard Ducarouge admitted years later, that the Ligier team never understood why their car was so good "out of the box" that year. In the second part of the season, they became unable to improve their car like other teams that initially struggled with theirs.
These were special cars, where the driver's shoulders are lower than the front tires, and are the velocity stacks of the engine.
Spa in 1966 - Gurney with the Climax-powered Eagle. A year later he won the race in the Weslake-powered car.
In my humble opinion, a three way tie for most beautiful F1 car between Gurney’s Eagle, the Ferrari 156 Sharknose and the Maserati 250F. Let the arguments begin!
