Zagato’s trademark: DOUBLE-BUBBLE 💯• After World War II, Ugo Zagato created a new design concept called “Panoramica,” characterized by a tall, streamlined roof inset with extra-large, compound-curved windows. This basic body design was patented in 1948 and applied to many cars through the early 1950s. It was around that same time that Zagato conceived another concept, one also based in aerodynamic studies and designed to provide an advantage on the race track. Reducing frontal area and overall height lowers wind resistance, so his compromise between a small frontal area and retaining driver and passenger comfort (and headroom for a racing helmet) was to blister an otherwise low roofline with a bulge over each seat. This treatment also added strength to the thin aluminum roof panel. • The Double-Bubble, as this roof treatment became known, was first used on some of the later 1952-1955 Fiat 8V Competiziones that Zagato bodied, and it was subsequently used on privately commissioned one-offs like the lovely 1954 Maserati A6G/54 2000 Zagato Coupe and 1957 AC Ace Bristol Zagato Coupe. • #KukukKnows #zagato #doublebubble #ccckukuk #drivetastefully #history #archive #knowledge #fiat

*Wissensstunde* Der Ur-Porsche – 1939, Vorabend des Zweiten Weltkrieges, die Menschheit kurz vor dem Abgrund: In Berlin herrscht der eine Tyrann, in Rom der andere. Nur kurze Zeit noch, dann stürzen Hitler und Mussolini die ganze Welt in die schlimmste Katastrophe der Moderne. Zwischen Berlin und Rom gibt es im Jahr 1939 viele Verbindungen. Darunter auch eine, auf die man nicht so schnell kommt: den Porsche Typ 64, genannt der „Berlin-Rom-Wagen“. || Deshalb sieht der Typ 64 nicht nur schnell aus. Er ist es auch. Angepeilt war ein Tempo von 140 km/h – im Durchschnitt! Und das bei nur 32 PS und 0,98 Litern Hubraum. Allerdings wiegt das Auto auch nur 525 kg, ist aerodynamisch optimiert und seiner Zeit um Lichtjahre voraus. Wohl nicht ganz zufällig erinnert das hypermoderne Sparmobil VW XL1 in seinem Aufbau frappierend an den 75 Jahre alten Porsche. || Die weit bis ins Dach hineingeschnittenen Türen des Porsche Typ 64 öffnen sich zwar fast zu 90 Grad, aber ein bequemer Einstieg ist für Insassen jenseits der 1,80 Meter Körpergröße wie ein Origami-Spiel für Fortgeschrittene: Es will sich kompliziert gefaltet sein. Doch Leidenschaft ist ein hervorragender Schuhlöffel – hineingleiten und losfahren. || 🧐📚📖 #engineering #drivetastefully #ccckukuk #KukukKnows #wissensstunde #porsche #berlinromwagen #LuftMUC

*Wissensstunde* "Fahrzeug mit Gasmotorenbetrieb" aka Benz Patent-Motorwagen von 1886 🧐 Der Benz Patent-Motorwagen ist das erste Automobil der Welt. Carl Benz hat es 1885 konstruiert und am 29. Januar 1886 als "Fahrzeug mit Gasmotorenbetrieb" zum Patent angemeldet. Das Patent Nummer 37435, erteilt vom kaiserlichen Patentamt in Berlin, ist die Geburtsurkunde des Automobils. Carl Benz hat sich nicht damit begnügt, einen bestehenden Wagen mit einem Motor zu versehen. Bei seinem Patent-Motorwagen sind Motor, Fahrgestell und Antrieb von Grund auf neu konstruiert. Mit Benzinmotor, Zündung, Kühlung, Kraftübertragung, Rädern und Bremsen ist es die Urform eines jeden Autos, das seither gebaut wird. Nur für die Lenkung findet Benz keine überzeugende Lösung. "Weil ich mit der Steuerung theoretisch nicht fertig wurde, entschloss ich mich, das Fahrzeug dreirädrig herzustellen" sagt er später. 1893 wird Benz auch auf das Lenkungs-Problem eine Antwort finden. 🧐📖📚 • #KukukKnows #wissensstunde #benzpatentcar #benzpatentmotorwagen #history #knowledge #deutschesmuseum #mercedesbenz

*Wissensstunde* Part 2: Die selbstragende Karosserie war erfunden. Ab dem Zeitpunkt dieser Erfindung wurde die Rahmenbauweise Schritt für Schritt verdrängt. Die selbstragende Karosserie besteht aus miteinander verbundenen Schalen, an denen die Türen und Hauben über Scharniere befestigt werden. Alle Teile sind aus einzelnen Stahl- oder Aluminiumblechen gefertigt. Durch mehrere Umformungsprozesse kann jedes Blech in die gewünschte Form gebracht werden und anschließend durch Verschweißen oder Kleben mit dem Rest der Karosserie verbunden werden. Lediglich die Kotflügel werden mit der Karosserie verschraubt. Folgende Vorteile sind hierbei von Bedeutung: Das Fahrzeug des Gewichts reduziert sich, die Steifigkeit des Aufbaus nimmt zu, der Schwerpunkt wird niedriger, Raumangebot bleibt hierbei jedoch identisch und dabei erhöht sich die passive Sicherheit. Als erster deutscher Automobilhersteller wagte sich Opel, mittlerweile in amerikanischen Besitz übergegangen, an die selbsttragende Karosserie mit dem ‚Opel-Olympia‘, wessen Name Bezug auf die Olympiade in Berlin 1936 nimmt. 🧐📖📚 • Opel-Olympia from 1936 💯 • #engineering #drivetastefully #engine #ccckukuk #deutschesmuseum #kukukknows #wissensstunde #knowledge #history #opelolympia

*Wissensstunde* Part 1: „Von entscheidender Bedeutung für die Weiterentwicklung der Automobilkarosserie war der Übergang von der aufgesetzten zur selbsttragenden Karosserie“, so beschreibt Hans Straßl die Bedeutsamkeit der selbsttragenden Karosserie. Anfang der zwanziger Jahre entwickelte Vincenzo Lancia den Lancia „Lambda“ mit einer Konstruktionsbauweise die den Automobilbau fortan veränderte. Der Chassis Rahmen, aus Längsträgern und Quertraversen bestehend, wurde bei diesem Wagen durch eine selbsttragende Struktur aus geschweißten Stahlblech ersetzt. Diese Bauweise lag folgender These zugrunde: Der Chassis Rahmen muss alle auf das Automobil in ihrer Gesamtheit wirkenden Kräfte und Beanspruchungen auffangen. Die auf den Chassis Rahmen aufgesetzte Karosserie entlastet nicht das Chassis, sondern sie belastet es zusätzlich. In Vincenzo's Worten: „Rahmen und Karosserie unterstützen sich nicht gegenseitig in ihrer Funktion, sondern arbeiten geradezu gegeneinander…“. 🧐📚📖• Lancia Lambda from 1922 💯 • #engineering #drivetastefully #engine #ccckukuk #knowledge #history #lancia #makelanciagreatagain #kukukknows

Tonight I would like take you back to my previous introduction to material analysis as an authentication method and explain the functionality of the Spectrometer 🔬 • In my previous, technical post (Porsche 911) I have started talking about the materials itself, please read back if you missed it. 📖 This knowledge forms the basis, together with a material analysist to define the decade of production of the material/part itself. Now I would like to talk about HOW the material is analyzed 🌈 • An optical spectrometer (often called spectrometer) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials such as iron, steel and aluminium. Spectrometers show the intensity of light as a function of wavelength or of frequency. The deflection is produced either by refraction in a prism or by diffraction in a diffraction grating 💥• The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. 👀Electromagnetic radiation in this range of wavelengths is called visible light. The spectrum division used by Isaac Newton, in his color wheel, was: red, orange, yellow, green, blue, indigo and violet; a mnemonic for this order is "Roy G. Biv". 🏳️‍🌈 In modern divisions of the spectrum, indigo is often omitted • Because each element leaves its spectral signature in the pattern of lines observed, a spectral analysis can reveal the composition of the object being analyzed, for example the frame of the historical vehicle of concern 💡• In order to be able to take the measurement the part needs to be revealed until its bare metal (check photos in previous post to see the measurements) • Being now able to tell which components the material consists of, combining that with the basic knowledge of iron, steel, aluminium etc. productions and you will be able, together with the help of a material analyst, to tell in which decade the object was produced. Of course this again will help identifying the production year of the car or whether it was previously involved in accidents etc. 🏎💨💨 • For further information / break down ask any time 💯

Today, I would like to start introducing one of the many methods we use to authenticate a car for its originality 🚘 • In order to authenticate the age and material of a certain part of a car, we helped developing a machine which helps us analyzing the material without destroying the object and on site. The Spectrometer is displayed on fourth picture, second and third show the details. 🔬• The stationary laboratory which has been used over decades, meant that material, the size of a stamp, needed to be removed from the car and send in to be analyzed at the stationary laboratory. Obviously removing material from a car and therefor destroying the structure in a way is not what we should aim for. 🥈• The material analysis helps to break down the the material into its subelements in percentage. Now, if we take steel (iron with less than 4% carbon) as a material example, it has been developed in its production processes over the decades. This means, that depending on the percentage of e.g. carbon, aluminium and phosphor and the usage of other subelements, with these we can identify from which decades the certain piece of material is. 📡• Let’s say we are looking at a frame of a vehicle and would like to identify its production decade and try to match that with the production stamp of the vehicle. In the middle age the blacksmith produced swords and by heating the iron and with mechanical force, the material became much stronger. Due to the mechanical force O (oxygen) was added which chemically connects with C (carbon) and then removed in form of gas as CO and CO2. Only about 4% carbon were left, the invention of steel was fulfilled. End of the 19th century, when the “Tour Eiffel” was being built, a different type of steel was being used, called “Puddelstahl”, a method of steering. Then “Thomas Stahl” (blowing process) and since 1920th the steel production is being leaded by “Siemens Martin Ofen”, which insert oxygen by using recycled materials 🔬 • During the process of removing more and more carbon, elements like Silizium, Aluminium Sulfur and phosphor were also added to avoid the material to be too brital and easier to form 🏎 • Stay tuned for more details! 😊

Sunday’s are garage days 🔧🔩❤️⚙️🔨 • I have the pleasure, as part of my MG TD restoration project, to overhaul the engine and gearbox at one of the greatest garages around and THE Lancia specialist in Germany: B&F-Touring Garage owned by Peter Bazille. I have nearly finished this project but am just started overhauling a O.S.C.A (Maserati) engine and will take you through both of the restoration processes 💯 • 🔩⚙️The cylinders are the main part of any engine and is where compression and combustion takes place. Let’s show this on my engine, a 2-litre engine has a cylinder cubic capacity equal in volume to 2 litres (0.5 litres per cylinder in a 4-cylinder engine). The mixture, fuel and CO2, is then compressed ready for ignition and combustion within the cylinder. The ratio of compression is another key element in an engine and if it is too high you can create engine knock also known as detonation so this is another thing to factor in when increasing the cylinder capacity of an engine. A cylinder comprises usually a cast iron block but in some engines constructed of aluminium there is a steel liner fitted such as those pioneered by Alfa Romeo. 🔧💡❗️• Stay tuned to follow up my restoration process and look out for my complete story on @petrolicious 👹 • NOTE: the engine is obviously not from the Bentley 🤣 and SORRY for the blank pages once again, I am positive that my disputes with instagram are going to be solved eventually 🙈
