Also, don’t forget the Benz Tropfenwagen from 1922. Even though the ancient scholar tried to define the field, actually the qualitative … But the German Wikipedia says (in Google translation) “The aerodynamic design, however, the impaired driving safety of the car and made ​​it strong Schlör susceptible to crosswinds.”. I have another car that you could include; the 1939 Maybach Stromlinien Karosserie (aka Stromlinienkarosserie), which was a car that was made to do high speed tire testing: http://www.maybach.de/images/263_1.jpg https://en.wikipedia.org/wiki/Aurel_Persu. I wouldn’t call the current VW Passat impractically small, and it’s sold in India. Also, I’d very much like one of those Lincoln’s please…good restorable condition is fine. My grandparents never owned a home. Citroen DS racing car, check. Designers “forgot” about streamlining as a design goal because, by the 50’s with all of the advancements in aerodynamic understanding, they realized that the designs would become asymptotic. Very beautiful streamlined bodies that also incorporated advanced engineering. I have read that the perfect aerodynamic shape is that of a teardrop, with the blunt end leading. Automotive aerodynamics is the study of the aerodynamics of road vehicles. Tatra became synonymous with the advanced streamliner of the pre-war era, enabling remarkably fast travel (100 mph) on the fledgling Autobahns of the Third Reich. You’re very welcome! Hungarian-born Paul Jaray used his experience working in the aeronautical field, especially designing Zeppelins, to develop a specific formula for automotive aerodynamic design principles that lead to a patent, applied for in 1922 and issued in 1927. One of the things I love about aerodynamics is that little changes can make big differences too. Come check out all the different pictures and details about aerodynamics in race cars explained and so much more. What I always found interesting about aerodynamics is how the mainstream automobile industry forgot about them from ~1950 to ~1980. Jaray only addressed the aerodynamics, not the complete vehicle like Rumpler had. That would not be bettered until 1924, and not until 2009 for steam powered vehicles. I recall reading that due to a mathematical miscalculation, the Airflow’s structure was roughly twice the strength required for the application. Dirty Car” and you should be able to find the episode. I’ve wondered since I was a child why cars don’t have dimpled surfaces like golf balls. But still a stunning design. The aerodynamic efficiency of a car's shape is measured by its co-efficient of drag (generally known as its Cd figure). To arrive at the critical total aerodynamic drag that determines power required and efficiency, the frontal area (cross section of the vehicle looking straight on) is multiplied by the Cd. Read all about it and the great details in … The importance of these is never more important than in Formula 1, where due to the forces being exerted on the cars and the drivers, it would be impossible to … Below is a list of some and their contributions. But getting there was not without turbulence. The Russians took the Schlörwagen as war booty and conducted tests on it as a propeller driven vehicle. Look foward to the new series. A much more radical approaches to streamlining was Buckminster Fuller’s Dymaxion. It reduces drag on a golf ball, but would increase drag on a more aerodynamic shape like an airplane (Cd around .02). Another one you might want to check on as an American example would be the Auburn Boat Tail Speedster of 1929 and the succeeding models through the early thirties. The commentators there were, well, eager to lump everything into Libs vs Dems vs Reps vs younameit; that put me off. Progress is not always linear. To arrive at the critical total aerodynamic drag that determines power required (and efficiency), the frontal area (cross section of the vehicle looking straight on) is multiplied by the Cd (Cd x Ft²). I had to come back here (Article 1) to jump to 3. Copyright 2011 - 2020 Curbside Classics. His early designs tended to be very tall, and with questionable proportions and space utilization (below). Headway in the world of aerodynamics was being made one lap at a time on racetracks across the world. To demonstrate just how rapidly and far the aerodynamic envelope was pushed in this golden decade of streamlining, this 1939 Schlörwagen prototype was tested originally at Cd 0.186, and a model of it was retested by VW in the seventies yielding a Cd of 0.15. That was too much of  a break for the symbolism still engendered in the remnants of the classic car prow. CC: Thanks for the compliment, but no need to link back to the old series, since I have expanded it and updated it for CC. Search for “Mythbusters Clean Car vs. They are becoming quite rare. The championship is today held in accordance with well-formulated rules and regulations, and incredible efficiency. The efforts to do so yielded some of the more remarkable cars ever made, even if they challenged the aesthetic assumptions of their times. Enjoyed the English Burney ad saying: “slight wear on the tires”. I had the kids watch the land speed movie with the guy from coach and do some reading before they started. Early “aerodynamic” cars tended to utilize “teardrop” form and rear engine configuration. I love this stuff, too. Metal would twist and tear. This fairly radical design became tamed-down for the production 1936 front-engined Lincoln Zephyr, of which the less common but handsome coupe version is shown below: Of course, Americans’ introduction to streamlining had come two years earlier  in 1934, with the stunning Chrysler Airflow (below). I too have known about the Airflow for years; but this is the first one I have seen in person. We’ll come back to Tatra later. my e mail at kdfvw@yahoo.com Great read! A dimpled surface would decrease pressure drag but increase friction drag, so it may or may not be a benefit, depending on the shape of the vehicle. We’ve finally arrived at the place where highly aerodynamic cars are mainstream, but getting there was not without considerable turbulence. I think I have spotted the remains of an Airflow in a field outside of Dallas; need to study it closer; and if correct, take pictures of it. please e mail me. Of course, Americans’ introduction to streamlining had come two years earlier  in 1934, with the stunning Chrysler Airflow. For example, a flat plate held at right angles to the airflow has a Cd of 1.25, whereas the most efficient production car shapes at the moment have a Cd of about 0.28. http://members.chello.nl/j.baartse/carpics/venusbilo.jpg, http://en.wikipedia.org/wiki/Volvo_Venus_Bilo. Your email address will not be published. It also explains the particularly strong interest and adoption of streamlining in Germany, where these early VW prototypes (VW 30) are shown being tested. Great article, Paul. At the time anyway, the lowest cd was an experimental mercedes that was designed after a fish. However, I’ve been a read-only user of TTAC for a long time, and CC since inception. Dreamers, engineers, racers and entrepreneurs were lured by the potential for the profound gains aerodynamics offered. As for the Airflow, it was my understanding that it was a “semi-unitized” construction that the engineers referred to as “bridge truss” construction. The failure of the practical Airflow can probably comes down to one thing: that overly flat waterfall grille. Why did they make these? . Victor. It turns out that Erwin Komenda, who actually penned most of Porsche’s design and the KdF Wagem, visited the US in 1934, saw Tjaarda’s prototype, and admits being influenced by it. To demonstrate just how far the aerodynamic envelope was pushed in this golden decade of streamlining, this 1939 Schlörwagen prototype was tested originally at Cd .186, and a model of it was retested by VW in the seventies with a Cd of .15. The Zephyr had one, and it was a success, despite not being nearly as a good a car as the Airflow. Note that I have not attempted to survey the influence of aerodynamics on the styling of cars in the latter thirties and up to WW II. I too look forward to the rest of the story. Aviation engineer William B. Stout designed this extremely roomy mini-van precursor using  a unitized body structure and a rear Ford V8 engine. The first cars were made before the Wright brother’s era and before the invention of wind tunnel tests. It’s 4.8 meters long and has loads of passenger room and a huge trunk. That earned it the nick name of “the Czech secret weapon”. This made it a forward looking undertaking, as most drivers were still  plodding along at 35-45 mph outside of cities. Neil, Varying cars had varying front wing widths, and you can see that some vortices actually hit the front tyre and are destroyed. I’ve known about the Schlörwagen for a few years now (the folks at EcoModder.com are big fans of aerodynamics!) Is the DS going to appear in the next installment? The mainstream industry forgot because the mainstream public did not care. But this had relatively more to do with style (and even affectation) than a genuine effort to push the envelope in terms of leading edge aerodynamics. As this 1934 prototype for an American rear-engined sedan by John Tjaarda shows, the Europeans weren’t working alone. The result was a striking Tatra-like car, with great detailing (e.g. When I said the motor looked just like a bug, he got a little hot and I learned about Porsche stealing the design. Multhopp designed the P.183 and is famous for his T-tail designs. I love the “Tropfenwagen”. http://www.volkswagen.co.in/en/models/newpassat/gallery.html, well, Europeans haven’t got a Small Car Syndrom, neither have the Asians, they build cars in which they fit in easily… I think American cars are made for the “We Americans are eating too much fastfood so we don’t fit in a normal car anymore” syndrom . That was too much of  a break for the symbolism still engendered in the remnants of the classic car prow. Hopefully he was kidding. The lowest Cd production cars at 0.25 include the current Prius, which is a great looking car to my eyes, and this special aero version of the E-Class Mercedes. The year was 1899. An even less pragmatic but remarkably practical and effective American vehicle was the Stout Scarab (above). Of all the cars, two stood out. The Tropfenwagen was tested in VW’s wind tunnel (below) in 1979, and achieved a Coefficient of drag (Cd) of 0.28; a degree of slipperiness that VW’s Passat wouldn’t equal until 1988. A full size car can hold 27 gal on a fill up. Yes, I think they do, absolutely. With its .22 Cd and significantly reduced frontal area, it's no wonder this … Very slick. This Volkswagen prototype from 1934 (above) shows a very strong resemblance to the cribbed Tatra v570, with the benefit of some further refinement. Granddaddy sold Chryslers in New York in spring/summer, then drove a company car to Palm Beach to sell them there each winter, and knew Walter Chrysler. In their quest for dominance in the late 1960s, Ford and Chrysler started a head to head competition to design the ultimate NASCAR vehicle. Mercedes-Benz A-Class. That brings back memories of Bob Lutz stating that the Volt concept would have had better aerodynamics if they put it in the wind tunnel backwards. Fascinating article. Where To Download A History Of Aerodynamics By Anderson aerodynamicists of our time. It represents a state of aerodynamic efficiency in league with the most aerodynamic prototypes today, such as the Aptera. The evolution of aerodynamics for LSR cars was rapid, as this Stanley Steamer Rocket of 1906 evidently shows. “Der KDF Wagen” is huge!! P.S. When I started this article, I assumed it was the earlier one transplanted to CC. And the increase in speed was even more dramatic: the Rocket broke the 200km barrier, with a run of 205.44 kmh (127.66  mph). Agreed- this is great stuff! It’s made in 1938, I can’t remember a design earlier than that, with fully integrated fenders all around. An essentially pragmatic approach, the Airflow also kept the traditional Body On Frame (BOF) front-engine RWD standard, but made some significant advances in terms vehicle design by pushing the engine further forward over the front wheels. The compact Tatra v570 of 1933 (above) is the forerunner of both the larger Tatras soon to come, and obviously of the Volkswagen. Porsche/ VW settled with Tatra in 1961. http://blog.goo-net.com/chez2007/img/163/inline_15.jpg. Aerodynamics has become a key to success in the sport and teams spend millions of dollars on research and development in the field each year for improving performance. This is probably how the car could fall end over end off a cliff and then drive away without even any broken glass. There is not a chassis really, the body is supported from transverse supports hung from the engine/transmission, torque tube and rear axle. Needless to say the influence was utterly profound, and gave us some of the most remarkable cars of the late classic era. Given below is the brief description on F1 history. I don’t know much about the history or whereabouts, more than it was based on a Volvo chassis, and built in 1933. It also explains the particularly strong interest and adoption of streamlining in Germany. In 1983, the flat-bottom regulation came into force, which prohibited all aerodynamic aids that generated downforce on the underside of the cars. But this had relatively more to do with style (and even affectation) than a genuine effort to push the envelope in terms of leading edge aerodynamics. In common with many of the cars featured … I always look forward to your consistently informative, insightful, and interesting articles. F1 car racing has astounding number of followers in all parts of the world. I especially like the “Flying Hamburger” – a train in Germany! Let’s jump back to Czechoslovakia and the fertile Tatra design studios. So many died at its hands, that allegedly Hitler forbade his best men to drive them. Hungarian-born Paul Jaray used his experience working int the aeronautical field, and especially designing Zeppelins, to develop a specific formula for automotive aerodynamic design principles that lead to a patent, applied for in 1922 and issued in 1927. The buying public was perceived or conditioned to need change, and the rounded pontoon gave way to ever-more dramatic and flamboyant but aerodynamically blunt designs. The latter is on my bucket list to this day, and may have about as much chance of happening as the red stag hunting trip in the Scottish highlands. That combination of light weight and outstanding aerodynamics would make a perfect commuter car. The limitation of these cars is like the Castagna Alfa, they were re-bodied conventional cars with frames, front engines and RWD. The failure of the Airflow probably comes down to one primary aspect: that overly flat waterfall grille. I go to a fellow E28er’s get together. This would later go down in history as the “Aero Wars” of 1969 and 1970. It’s important to remember that the Cd is a coefficient, and denotes the relative aerodynamic slipperiness of a body, regardless of its overall size. Paul, you’re one of my top favorite car guys. Air is also considered a fluid in this case. The origins of streamlining go back two hundred years at least. I’ve been to the Lane Motor Museum in Nashville, and it’s someplace everyone needs to go. The Rumpler’s shape was very aerodynamic, but it was also quite tall and boxy, which resulted in the one hundred or so production cars being used primarily as taxis puttering around Berlin because of their roomy minivan-like bodies. Unfortunately, the Benz Tropfenwagen was not an instant success and when Daimler and Benz started to cooperate (and later merged), Mercedes got in charge of all the racing efforts, effectively scrapping all Benz & Cie designs, so the Benz Tropfenwagen never got the attention and further development it deserved. Racers, particularly those chasing the coveted Land Speed Record (LSR), were generally the first to employ aerodynamic aids. . His early designs tended to be bizarrely tall, and with questionable proportions and space utilization. All Rights Reserved. You have done again Paul. The Dymaxion also had a rear Ford V8, but with a tricycle carriage and rear wheel steering, which allowed it to turn on the length of its body. During the fifties and sixties, with the exception of Citroen, Saab and a few other minor adherents, aerodynamics was largely left in the wake of increasingly ornate and boxy cars. Peugeot was working on a V8 at the time, and an 802 streamliner was rumored to use this shape for the 1940 Paris automobile salon. Paul, History & Evolution of Aerodynamic In CarsCar design in 1920:- In the earlier times aerodynamics was not a factor as the cars where traveling at very slow speeds, but with increase of speeds it is necessarily for cars to become more streamlined, which resulted in smooth design and almost all corners of car are rounded off . I don’t agree the modern aerodynamic cars are ugly though. The first was built in 1932, and several more variations, a total of nine, were built in the mid thirties, but series production never got off the ground, due to an asking price almost four times higher than a Chrysler Imperial Airflow of the times. American Brands: AMC, Jeep and All Others, Tractors, Lawn Mowers, Off-Road Equipment, Automotive History: An Illustrated History Of Automotive Aerodynamics – Part 1 (1899 – 1939), http://www.thetruthaboutcars.com/2010/02/an-illustrated-history-of-automotive-aerodynamics-in-three-parts/, https://en.wikipedia.org/wiki/Aurel_Persu, Curbside Capsule: 1989 Chevrolet Caprice – Please Pass The Margarine. One of the most influential and lasting designers of the whole era was Austrian Hans Ledwinka. I know wings and radial engines clutter things up but still…. According to Paul Schilperoord, who’s written about Josef Ganz, http://www.ganz-volkswagen.org/, Porsche, Ledwinka, and the European automotive scene in the 1920s and 30s, the patent dispute between Tatra and what became VW mostly had to do with the design of air-cooled horizontally opposed engines. The luftwaffe staff dying of oversteer on the autobahns–Ludwinka’s revenge! I always thought GM should have taken the EV1, emptied the battery pack and motor and just added as small Tdi like found in modern VW Bluemotion Polo. Cars were made to LOOK aerodynamic, but, until the oil shortage of 1973, nearly nobody cared about efficiency, and it’s only fairly recently that enough of the public expect it, and the industry has to deliver aero. Still, we could learn well from the simplicity of these designs…, http://www.amazon.com/Streamline-Era-Robert-Carroll-Reed/dp/0870950533. The Airflow had the same basic configuration as American cars from the late forties and early fifties. The first of several prototypes also saw the light of day in 1933, in the midst of this fertile period on both side of the Atlantic. His approach was influential, and numerous companies used Jaray licensed bodies during the streamliner craze that unfolded in the early thirties. It was a start, but others were taking up where Rumpler left off, like the English Burney, below: Obviously more Rumpler influenced and less by Jaray, the 1930 English Burney featured a then-radical rear engine and also four wheel independent suspension. Required fields are marked *. Built on the chassis of the rear-engine Mercedes 170H, it was substantially faster as well as 20% to 40% more fuel efficient than its donor car. The Dymaxion also had a rear Ford V8, but with a tricycle carriage and rear wheel steering, which allowed it to turn on the length of its body. Here are a couple good examples of aerodynamic cars: the 1989 Chevrolet Corsica hatchback and the 1999 Ford Taurus sedan. And the increase in speed was even more dramatic: the Rocket broke the 200km barrier, with a run of 205.44 kmh (127.66  mph). The Tatras and other streamliners are beautiful. After he took over as chief design engineer at the Czech firm Tatra in 1921, he developed the basis of a series of remarkable Tatra cars and eventually streamliners with platform frames, independent suspensions and rear air-cooled engines that Ferdinand Porsche cribbed from heavily in his design of the Volkswagen (VW made a substantial payment to Tatra in the 1960s to compensate them for this theft of IP). Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. If I had a V8 powered bug when I was a kid, I prolly would not be here now. The mainstream industry forgot because the mainstream public did not care. Thank you Paul. Tatra became synonymous with the advanced streamliner of the pre-war era, enabling fast travel (100 mph) on the fledgling Autobahns of the Third Reich. A much more radical approaches to streamlining was Buckminster Fuller’s Dymaxion. For those who don’t know or remember, here’s the link to the previous series, when Paul (and CC) were still at TTAC: http://www.thetruthaboutcars.com/2010/02/an-illustrated-history-of-automotive-aerodynamics-in-three-parts/. Like all the first batch of LSR holders, it was an EV. The pictorial of the restoration started with a rusty pile of old car parts. Aerodynamics is a branch of dynamics concerned with the study of the motion of air. Therefore, the designers devote an enormous amount of effort taming the airflow and generating downforce – just as their predecessors did, when this quest first started 35 years ago with the first wings of the Formula 1 cars… I have not attempted to survey the broader influence of aerodynamics on the styling of cars in the latter thirties and up to WW II. Fascinating stuff–the Schlörwagen looks futuristic even now. In 1936, Peugeot had a handful of 402 sedans rebodied by Andreau, a French disciple of Jaray. The original Saab and of course the infamous Citroen DS and SM. I appears to have  Isetta-type front doors for the front seat passengers. The first known attempt at streamlining a passenger car is this Alfa Romeo from 1914, built by the coach builder Castagna for the Italian Count Ricotti. I know, making the occupants the size of midgets was the thing back then. Here are some clays from about 1933 or so, showing the development of both the smaller VW-like v570 on the right, and the larger streamliners in the rear. And the increase in speed was even more dramatic: the Rocket broke the 200km barrier, with a run of 205.44 kmh (127.66 mph). The cross-Atlantic influence were well at work already, although back than it was usually in the other direction. through the flow. We’ll come back to Tatra later. The Rumpler was relatively very aerodynamic, but it was also quite tall and boxy, which resulted in the one hundred or so production cars being used primarily as taxis. Plenty of microcars, check. After all, the energy used to overcome air resistance cannot be recovered – unlike with vehicle acceleration. Its important to note that the rise of interest in aerodynamics in the 1930s arose out of the desire to reinvent the automobile from its horse and wagon origins and the assumptions that average driving speeds would be on the rise with modern roads. The same approach is followed in India, even today. Vintage Snapshots: Exploring the Southwest and Mexico in a 1953 Ford, Curbside Classic – 1958 Chevrolet Delray Two Door Sedan, eBay Classic: 1957 Plymouth Belvedere Sedan – Fairest Among Ten Thousand. If I recall correctly, the late-80’s GM A-bodies (Chevy Celebrity et al) especially the station wagons had remarkably low drag. 1968: When Formula One Cars Grew Wings. The Model 3, when tested, clocked a 0.21 drag coefficient. The cars were then given narrower designs again, so the developers began to turn their attentions to small aerodynamic details. My info is that it had a Cd of 0.16, and it could go 150mph with a 150HP engine. The “Dymaxion” name brings to mind a gas analyzer I helped to develop some time ago, by the same name: http://www.ceb.uminho.pt/labs/reequip/MS_58305_64351.jpg It is a sub-field of fluid and gas dynamics, and the term "aerodynamics" is often used when referring to fluid dynamics He bought the local doctor’s ’33 Tatra roadster. Jaray only addressed the aerodynamics, not the complete vehicle like Rumpler had. Then in the 40s the mass market engines got more powerful and aero could be sacrificed to style. The driver’s position seems to negate the aerodynamic aids, or maybe he was just posing, and more likely crouched down for the actual run. To put the nascent field of automotive aerodynamics in perspective, the typical two-box car of the twenties was more aerodynamic going backwards than forwards, as this ass-backwards DeSoto proved in tests. His approach was influential, and numerous companies used Jaray licensed bodies during the streamliner craze that unfolded in the early thirties. To put the nascent field of automotive aerodynamics in perspective, the typical two-box car of the twenties was more aerodynamic going backwards than forwards, as this ass-backwards car showed. A stunning achievement, the long-tailed T77 was powered by a rear air-cooled V8, and began a long series of Tatras until the 1980s along similar lines. The ’57 300, and the Airflow. It's unpleasant to think about, but imagine what would happen if you drove your car into a brick wall at­ 65 miles per hour (104.6 kilometers per hour). The ’30s Peugeots (402, 302 and 202) shamelessly copied the Airflow, though they looked better and were a success. Thank you. The Tatra seems to have been the commercial design closest to the ideal during this era. The resemblance of the production KdF Wagen to Tjaarda’s 1934 prototype, especially certain details of the front end, seem like a bit too much of an accident. For the Tatra fans a link to a (German) website with interesting pics: http://www.zuckerfabrik24.de/autos/tatraplan_1.htm. There is a basic tension between aerodynamic engineers and car designers. Your email address will not be published. That air presented the greatest obstacle to automotive speed and economy was understood intuitively, if not scientifically since the dawn of the automobile. [Continue to Part 2]. Limousines, sedans, coupes, convertibles — including an electric hardtop version — were proposed. Nevertheless, the benefits and beauty that resulted, like in this Bugatti Atlantique coupe are undeniable, but beyond our scope here. I’ll add it to a revision of the text. The efforts to do so yielded some of the more remarkable cars ever made, even if they challenged the aesthetic assumptions of their times. All in beautiful shape. Sorry, no quick link. Airplanes often do have rough skins immediately ahead of control surfaces, but that’s for maneuverability, not drag reduction. As engine development began producing diminishing returns, designers turned their focus on aerodynamics. A SHORT HISTORY OF FLIGHT The theory of aerodynamics is the culmination of the works of many individuals. Part 2 and 3 will be here shortly. Another lesser-know variation of the popular Ford V8 engined aerodynamic vehicles was this Dubonnet Ford of 1936, whose very slippery body allowed it to reach 108 mph. So many died at its hands, that supposedly Hitler forbade his best men to drive them. Learn how your comment data is processed.
