Arrival of the future, in 1935 – Volvo PV36 celebrates its 75th anniversary
Visually different from most of its contemporaries, and totally different from every other Volvo car. The Volvo PV36, perhaps better known as the Carioca, is an exciting chapter in the Volvo history. It is also quite famous in automotive history if you consider how few examples were actually built and by such a small manufacturer like Volvo.
In 2010 the PV36 celebrates its 75th anniversary – and let us right from the beginning state: It is not a copy of the Chrysler Airflow which it has been accused of.
The history of these cars is yet another version of the eternal question about whichever was first, the chicken or the egg. What is the truth? Yes, Chrysler was first to put its Airflow on the market in 1934, but that does not automatically mean that Volvo copied its styling. That could not have worked from a timing point of view since the Volvo made its debut less than a year later. Such short leadtimes do not exist even today, and definitely not 75 years ago.
At the beginning of the 1930s, annual sales of Volvos amounted to less than 1,000 cars. They were conventional and rather similar models; six cylinder engines in sturdy frames, steel panels on wooden body framework, separate wings and running boards, outside luggage trunks, upright radiators and separate headlamps. They looked like most cars did at the time, however unusually well designed and built. Responsible for the restrained styling of the first Volvo cars was artist Helmer MasOlle*.
One man's work
The Volvo PV36 which arrived in the spring of 1935 bore, however, no traces of the painter's hand. This car was one man's work and that man was Ivan Örnberg, a headstrong and versatile engineer who came to Volvo in 1931 from the Hupp Motor Co in Detroit, makers of Hupmobile. Without the interference of either Assar Gabrielsson or Gustaf Larson, the usually very engaged and interested founders of Volvo, Örnberg ran the PV36 project from start to finish. Almost. He died suddenly in the late summer of 1936 when the car was just little more than a year.
From where did Ivan Örnberg get his inspiration for the PV36, and how? At around 1930, aerodynamics and streamlined vehicles had become the objects of many a thinker and progressive engineer. This was the age of the large airships and their shape is maybe the most concrete example of these theories, plus a number of early locomotives, airplanes and car prototypes.There were several different prototypes around, but no car manufacturer dared to put anything in production until Hupmobile and Chrysler Corporation did it, almost simultaneously.
In 1933, however, Volvo did show a streamline car, but afraid of the reactions of the public used a private person as responsible front figure – Gustaf L-M Ericsson of telephone company fame. Ericsson was named designer of the car and the project was his brainchild. "Venus Bilo" used a Volvo 655 chassis and had a full-width body with a front not unlike that of the Hupmobile Aerodynamic a year later. Its smooth shape was rounded at the rear with the spare wheel slotted in horizontally and acting as rear bumper. The idea of the car was to cut fuel consumption and prevent the creation of swirling road dust by using a streamlined body with a fully covered underside. Interesting and daring it was a prototype and as such it stayed, disappearing in the 1950s.
To conceive, design, style and manufacture a car takes a lot of time and effort today, and did so also in the 1930s. To proceed from idea via drawings and scale models to a real car with all that is needed in terms of tools, components and production development, is a process that takes several years.
Ivan Örnberg moved back to Sweden in 1931. At that time neither Hupmobile – where he worked as an engineer – nor Chrysler had come very far with their streamline plans. Hupmobile not at all in fact, because they only got started in 1932 when Raymond Loewy** – maybe the most famous of all industrial designers and automobile stylists in automotive history – was hired by the company in order to boost sales of the slow-selling cars.
At the same time Chrysler's streamline man Carl Breer was still occupied with different scale models in the wind tunnel and Örnberg had already been working a year for Volvo. It is therefore not only difficult but merely impossible, to image a contact, let alone conversations, across the Atlantic between Breer, Loewy and Örnberg on the subject of streamline cars. And pictures could not be transferred quicker than by mail or personal messenger.
The first streamliners
At the beginning of 1934, the Hupmobile Aerodynamic was presented. From the windscreen and forward it had a certain plough like streamline shape, but the rest of it was rather conventional. It was good-looking though without any particular individuality. It had a fully-pressed steel body, including the entire roof, fitted to a separate frame and was from a technical standpoint not in any way extreme.
Extreme, however, describes the definitely more daringly styled Chrysler Airflow – and its cheaper sister car De Soto Airflow – that arrived during the spring of 1934. They had a one-piece rounded front or face, a grille that looked like a waterfall and low-positioned faired-in headlamps.
The body was streamlined with rear-wheel covers and a rear end matching the front end. As opposed to the Hupmobile, and later the Volvo, the Airflow was of unitary design with a very sturdy welded body construction that did not need for a separate frame. But those who did the Chrysler body pressings, however, were not yet capable of such a large pressing as the roof, which meant that this had to be filled up in the usual way with wooden rafters, chicken net and wadding, covered with fabric***.
This was also how the PV36 was going to look a year later. Even the Olofström press plant was not capable of such a large one-piece pressing as the entire roof. Still, the PV36 was Volvo's first car with a pressed-steel body. It rested on a separate frame with substantial cross-bracings but with a relatively short wheelbase. Both Hupmobile and Chrysler had long wheelbases, over three metres, which gave them a much slender look well in harmony with the styling. The PV36 had a 290 cm wheelbase which gave the body a round and chubby look that couldn't really transmit the feeling of flowing speed that the styling was supposed to do. It is interesting to toy with the idea of what the car would have looked like if Örnberg had used the 310 or 325 cm wheelbase instead, both of which were standard at Volvo at the time and used for other models.The artist who did the drawings for the sales brochures and other promotional material did his best to stretch out the car in order to improve its looks but the reality was still there.
But, the Volvo PV36 had a technical upper hand over both the Hupp and the Chrysler, unfortunately not to be seen from the outside but felt when driving: it used an independent front suspension – with the front wheels moving independently of each other during vertical movements – which greatly improved handling and ride as opposed to a beam axle.
The Volvo PV36 was equipped with the latest six cylinder engine version, the EC of 3.67 litres capacity and with just over 80 horsepower. It sat below a bonnet which was integrated with the front where the headlamps were faired in, surrounding a traditional but nicely stylized Volvo radiator grille which followed the shape of the front rather than standing on its own like on other Volvos. The front wings were still almost separate and if the headlamps had been placed on top of them, rather than being blended into the front, the streamline ambitions would hardly have been noticed.
It is in fact the position and look of the headlamps that really make this car what it is, and remind the observer of the Chrysler Airflow. But calling the Carioca a copy cat would be wrong. The differences are too big and too many between these cars. And regarding the Hupmobile, there is virtually no resemblance at all.
The front bumpers of the Volvo and the Hupmobile have been said to be identical. Far from it. Indeed, both are V-shaped but the one on the Volvo is not so pronounced while the Hupmobile one has a sharper angle and follows the wing shape in a more elaborated way. The bumpers may, however, have been made by the same supplier but to different specifications. The Chrysler/De Soto bumper is completely different. Nothing there at all.
Volvo PV36 had both front and rear doors hinged to the B-pillar, like the Hupmobile, whereas the doors of the Chrysler and the De Soto were hinged the opposite way around: front door to A-pillar and rear door to C-pillar with the B-pillar used for locking both doors. Like the Airflow, the PV36 also had rear wheel spats with a small chromium decor. These decors, admittedly, are virtually identical at a quick glance. Maybe Örnberg saw it on the Airflow in 1934, was inspired and hurried to order something similar, or bought it from the shelf from the same supplier as Chrysler.
The rear end of the Volvo body was sloping with a split rear-window, and a built-in luggage compartment (the first on a Volvo) with the spare-wheel on the outside of the lid in its own steel casing. This was also roughly how the other streamline cars looked, but their luggage compartments could not be opened from the outside like the Volvo's.
The car of tomorrow – and yesterday
The designation PV36 had nothing in common with the logical numbering used on the other Volvo models. Instead it was thought to evoke a feeling that "the car of the future has arrived already today", in other words the 36 already in 1935. If those responsible for this had given it another thought, they would have discovered how quickly this thought about the future could be reversed into the opposite. The last PV36s were only sold in September 1938.
Of course all this new thinking could not come cheap. The price for the PV36 at the time of its introduction was SEK 8,500**** – 1,000 more than the De Soto Airflow and 1,000 less than the more exclusive Chrysler – which disqualified most car buyers straight away. Secondly, the high price in conjunction with the looks of the car scared off the potential Volvo buyers who could afford a Volvo but also wanted a Volvo to look like one. Other Volvo models at the time were priced between SEK 5,000 and 6,000. For the same price as the PV36, you could buy an American Packard 120 straight-eight or a six cylinder German Wanderer W50, the mini Horch. Beautiful luxury cars both of them. No wonder sales of the PV36 were slow. The following year the price was considerably lowered.
But why is the car called the Carioca, like the dance? It is actually not called Carioca but PV36. Carioca is only a nickname but it has persistently clung to the car during all these years and is maybe more known and used than the actual correct designation.
The swinging Carioca was danced for the first time in the Hollywood motion picture "Flying down to Rio" from 1933 by Fred Astaire and Ginger Rogers, in their first movie appearance together. It is a very passionate dance from Central America where the foreheads of the dancing couple must touch now and then during the dance.
Carioca is also the official nickname for a native Rio citizen. Because of the fact that Volvo's export to Brazil started very early, already in 1933, one can suppose that the name Carioca was used as a flirt with the Brazilian market in the sense that it would associate to the people of Rio rather than the dance. Some Cariocas did finally end up in Brazil
Gustaf Larson, one of the Volvo founders, drove one – it still exists in private hands in worn but original condition – and the Swedish police force bought eighteen patrol cars. Most PV36 customers were, however, according to the delivery book people who could afford a pricey car, people like company executives, industrialists, businessmen, lawyers, doctors etc.
As for special commissions, not much happened. Only one single car with a convertible body, made by the Nordberg Coachbuilding Co in Stockholm, was built on the PV36 chassis and commissioned by a wealthy businessman. The car had a two-door body, painted in a two-tone colour scheme, where most of the original details had been kept except for the roof. It would have been most interesting to have seen the price-tag of this car at the time. Like many other high-class and exclusive cars in Sweden during these years it had a short life and was unfortunately scrapped after some years only.
It may be interesting to know that fewer than 25 examples of the PV36 exist today, most of them in Sweden and in varying conditions.
Just like the Hupp Motor Co and Chrysler Corporation, AB Volvo in Sweden also had to accept the sad fact that cars like these did not really have a market in the mid-1930s.They were twenty years ahead of their time with their streamlined and unconventional bodies. Car customers – and Volvo customers in particular – wanted conventional styling in harmony with the times, small visual changes.
It the autumn of 1938 the last PV36 Carioca was sold*****. By then, the Volvo PV51 and PV52 had already been on the market for two years, founding the basis for all other Volvos to enter the market during the rest of the 1930s. Viewed from behind, these cars showed resemblance to the PV36 but they featured the traditional Volvo front; separate headlights and an upright radiator grille leaned slightly backwards. Meanwhile, the Olofström press plant had developed new tools and solved the problems with large one-piece pressings; these cars had all-steel bodies.
Some streamline key years
1931 Örnberg leaves Hupmobile and moves to Sweden and Volvo
1932 Raymond Loewy begins at Hupmobile
1933 Airflow available as wooden scale model
1934 Hupmobile Aerodynamic, Chrysler Airflow and De Soto Airflow are presented at the beginning of the year. The Airflows are of unitary construction. All have beam front axle and live rear axle.
1935 PV36 is launched in March, featuring independent front suspension
1936 Hupmobile Aerodynamic is discontinued due to slow sales.
1937 Airflow is discontinued after four years of constantly sluggish sales.
1937 Adler Autobahn is launched
1938 The last PV36 is sold, three years after its market intro. In total 500 cars and one bare chassis.
1940 Adler Autobahn is discontinued.
A common fact for all these cars is that they were built in relatively small numbers since sales never really took off. They were expensive adventures for the companies with regards to tooling and production equipment and at the same time very interesting from a technical and historical point of view.
Let us also once and for all on the 75th anniversary of the PV36 determine and agree that it is not a copy of the Chrysler Airflow. The Adler Autobahn which arrived in 1937, on the other hand, is more or less a miniature Airflow. The same front, the same profile, only slightly smaller
Volvo is neither a copy of the Airflow, nor the Hupmobile Aerodynamic. When Örnberg left for Sweden in 1931, there were no models or tools to look at. What could he have seen and where? On the other hand, it is a well-known fact that great minds think alike, and quite often at the same time. For instance, messrs Daimler and Benz built their respective cars only 100 km away from each other, knowing nothing of each others existence and they never actually met.
No, cast no shadows on Ivan Örnberg. In order to find a copy cat in the Volvo history, we have to blame Helmer MasOlle and go back to 1927. The Volvo ÖV4 looks exactly like the 1924 Hupmobile Touring! But that is another story!
* Helmer Olsson MasOlle (1884-1969) Swedish painter, designer and graphic artist. Specialised in portraits and landscapes and the one who did the Volvo iron logo trademark and designed the first ÖV4 and PV4 cars.
** Raymond Loewy (1893-1986) is most famous for the Coca-Cola bottle, the Lucky Strike cigarette pack and the late 40s/early 50s Studebaker cars. He also designed everything from pencil sharpeners and stamps to restaurant interiors and locomotives.
*** Weatherproof (at least initially) fabric, i.e. leather imitation, called pegamoid was often used for covering roofs or even whole car bodies before synthetic materials, like vinyl, were introduced.
**** In order to put SEK 8,500 in to perspective, it would have got you almost 1,800 three-course dinners in a decent Stockholm restaurant at the time.
*****PV36 with chassis number 500 (the last one made) was delivered from the factory on June 16, 1938. The car that was the last one to be sold was chassis number 450 and it went to Teheran in Iran, to be used by the Swedish ambassador there, von Heidenstam, the last week in September 1938.
