Chrysler TurboFlite show car




   TurboFlite was created in 1961 by the Italian studio Ghia based on sketches created by the chief designer of the American automobile company Chrysler Virgil Exner. Car had a number of original design solutions: a dome roof with panoramic windows, automatically lifted when opening doors, a high wing with active aerodynamics, placement of rear lights. In addition to the design, the power plant should have become a feature of the car - TurboFlite was planning to install the C2A gas turbine engine. However, the engine at the time of the presentation of the car, held in 1962 at the Chicago Auto Show, was not ready and only a wooden model was installed on the TurboFlite. TurboFlite was assembled only in one demonstration vehicle shown at exhibitions and it was not tested on roads.

   And again from IDEX-2019.




   Presentation of the Aurus at the international exhibition of weapons IDEX-2019 in Abu Dhabi.

   As part of the ongoing military and industrial exhibition IDEX-2019, the Tawazun Defense, Security and Development Fund (UAE), FSUE NAMI and PJSC Sollers signed an agreement on joining the Tawazun Foundation among the participants of Aurus LLC.

   In accordance with the signed agreement, Tawazun will receive a 36% stake in Aurus LLC and invest a total of 110 million euros in the company over the next three years. These funds will be used to invest in the organization of full-scale serial production of Aurus vehicles, in their localization, as well as in the development of distribution in international markets. The agreement also stipulates that the Tawazun Foundation will become the general distributor of the Aurus model line in the countries of the Middle East and North Africa.

   “The entry of the Tawazun Fund into the AURUS project is a clear indication that the luxury car line developed in Russia has every chance of becoming a successful product in the global market, and the project itself is commercially attractive to potential investors,” said Denis Manturov, head of the Ministry of Industry and Trade of the Russian Federation.

   FSUE “NAMI”, which will continue to be the developer of cars under the Aurus brand, will retain 63.5% of the company's shares. The share of PJSC Sollers in LLC Aurus will be reduced to 0.5%, while from the end of 2020 Sollers will become an industrial partner of the project and will begin mass production of Aurus vehicles at the facilities of an automobile plant in the special economic zone Alabuga.

   “I am confident that attracting a Middle Eastern strategic investor and the beginning of localization of Aurus in the UAE will become the starting point for the progressive and sustainable development of Aurus project both on the regional and global markets,” added Sergey Chemezov, general director of the Rostec state corporation.

   The project “Single modular platform” (“Cortege”, Aurus) was launched in 2013. For the first time, a Russian VIP car was used during the inauguration ceremony of Vladimir Putin on May 7, 2018.

One of the most striking exhibits of the upcoming Geneva Motor Show should be the supercar of the revived Hispano-Suiza brand.




   The newly revived Hispano Suiza presented the Maguari HS1 GTC supercar, which will be sold for 2,200,000 euros, while the delivery of cars to customers will begin before the end of this year. Of course, the number of supercars is limited - only 300 would be made.


   The manufacturer claims that the all-carbon supercar is "in the final stages of development". The new Hispano-Suiza will receive a significantly reworked 5.2-liter V10 engine from the Lamborghini Huracan, which, thanks to two classic turbines and two electric superchargers, produces 1085 hp and 1050 Nm of torque.





Hispano Suiza Maguari HS1 GTC can accelerate to 100 km/h in 2.8 seconds, and the maximum speed is electronically limited to 380 km/h.

Ferrari Studio CR.25 Concept Car




   Ferrari Studio CR.25 was created by Pininfarina as part of the work to reduce the drag coefficient, for which CR.25 was given a front bumper that acts as a spoiler, an air brake; the car was also equipped with special Pirelli tires with low rolling resistance and designed specifically for the CR.25. Thanks to the efforts made, the drag coefficient was only 0.25. When creating the car, components and assemblies of a mid-engine Ferrari Berlinetta Boxer sports car were used, in particular a 12-cylinder engine 512BB (?), 4.9 liters and 360 hp. Only one was made and presented to the public at the automobile exhibition in Turin in 1974.

That is a shockingly clean and elegantly simple  car for Cadillac,  of that era. If one replaced the greenhouse  with a similarly styled steel roof with conventional rear window, it would look even better.

Similarly, a convertable.


Compare this to the offerings in 59/60 and 61, and you'll see what I mean.


This looks very sharp.

Minivan Moskvich-3733




   The 8-seater minivan Moskvich-3733 was created on the basis of components of Moskvich-2141. Work on the creation of it was carried out by the Moscow Automobile Plant AZLK together with the Bratislava Automobile Plant. The Czechoslovak side was responsible for the development of the body, the Soviet - the chassis and engine. It was planned to equip a minivan with a 4-cylinder gasoline engine Moskvich-21414 with 95 hp or a diesel engine Moskvich-21413 with 85 hp. In 1988-1991 3 prototypes of the minivan were built, and a van based on Moskvich-3733 was also built in Bratislava. They discussed plans for the development of mass production in the USSR and Czechoslovakia, but failed to implement them

Australian RQ-7 sport car




   RQ-7 was built in 1964-1974 by Australian enthusiast Robert Quelch from Grafton. Such a long period of construction was due to the fact that almost all of the parts for the car were made by Kvelche themselves, the only node taken entirely from the side was the engine - Jaguar XK6

      Is there any way Sherman tanks could be upgraded at reasonable cost to still have a role on the battlefield? Assume that your military will never fight with a world-class army (U.S., Russia, China, etc.) and instead will only fight with second-rate armies using 1990s technology at best, or with terrorists, or go on peacekeeping missions. 
      I'm thinking that the Shermans could have their turrets removed and modern autoloading turrets from other armored vehicles--like the 105mm Stryker gun, or the 40mm autocannon from the CV10, or the 30mm from the BMP-2 (would any of these fit in the Sherman's turret ring?)--could be dropped in, along with their sensors and computers. ATGM launchers could be installed as well. Explosive reactive armor bricks could be attached to the outside, as is common among modern Russian tanks. 
      Assume that your Sherman fleet is 1,000 tanks, in various states of (dis)repair, so you have enough spare parts to last for many years. 
      What do you guys think? Thanks.

      So, basic introduction, to start off, we'll go with the latest backbone of the PLA Ground forces' Armored divisions, the ZTZ-96 G/A
      Basic specs.
      Crew: 3
      Weight: 42-45 tonnes depending on equipment and addon armor/era.
      Power plant: 1,000 hp liquid cooled Diesel engine
      Speed: 65 km/h on roads 45 km/h off road
      Range: 400km without external tanks
      Armament: 125mm L/48 main gun with autoloader similar to the Soviet 2A46 (8 rounds per minute rof), ATGM capable, based on Russian Refleks-M missile, also has HEI-FRAG, HEAT, and APFSDS ammunition choices, W-85 12.7mm cupola machine gun (not pictured in this photo), 7.62mm coaxial machine gun.

      Wow, such sharp looking, very armor.
      Capability wise, this tank was recently pitted against some modern T-72B variants in a Russian tank Biathalon, and while it was deemed better in Armor, Armament, and Electronics, it lost out in mobility due to the underpowered engine, this killed all 730 and 780 hp engines in other ZTZ-96 G/As for the 1,000 hp engine.
      One interesting note: the boxes on the side actually contain equipment that interferes with the targetting systems of SACLOS missiles, aswell as laser designators, rangefinders and guidance systems, these can be seen when the tank is viewed from above.
      The heavier, far stronger pride of the ground forces.
      ZTZ-99 (A2 variant pictured.)
      Crew: 3
      Weight: 54-60 tonnes depending on variant
      Powerplant: 1,500 hp turbo charged liquid cooled diesel engine
      Speed: 80 km/h on roads, 60 km/h off road
      Range: 600km without external tanks.
      Armament: ZPT98 125mm L/52 autloaded gun with 8 rounds/minute rate of fire (some sources quote later variants at 11 rounds per minute), higher pressure tolerances, redesigned autoloader and other improvements, this allows it to fire improved ammunition such as far more deadly APFSDS then other 125mm autoloaded gun platforms in the PLA's inventory, it can still fire all other types of rounds aswell, W-85 12.7mm cupola machine gun, 7.62mm coaxial machine gun.
      Armor: While the exact thickness and composition isn't known, It's known from cutaway photos and some are pubically released information to have a hard spall liner as many other tanks these days, the actual armor composition itself are plates of high strength/toughness maraging steel sandwiching materials such as high hardness Aluminum oxides, aswell as layers of Graphene and unknown materials from there (likely something very dense), the boxes on the side of the turret and on the pike nose on the front are likely addon ceramic armor as opposed to ERA as originally believed and may be hollow to act as spaced armed, aside from the physical armor package, the tank also features ERA, NERA, and active defense systems that jam or alter the trajectory of various types of guided projectiles.

      So, this is the actual "elite" tank of the PLA to supplement the cheaper 96's, Originally it started out with a modest $2,500.000 production cost, however, as time grew on and they kept advancing it to the lastest standards of a top tier MBT, that sort of spiraled out of control a bit, coupled with the fact that the PLA ground forces don't get the same funding as the PLAAF and the PLAN, and the result was that, while the 99A2 has turned out to be a beast in it's own right, it simply isn't feasible price wise to give every tank crew a Type 99A2, however this is probably one of the most underrated 3rd generation MBTs as it's rarely talked about and theres a fuck ton of misinformation about it (mainly that it's a clone of the T-72/T-80 which is completely wrong) and well, it's goddamn pretty, and that counts for alot.
      Be sure to check my other topics covering other branches of the PLA

      Wherein I tackle the idea of hydrogen fuel cell technology in private vehicles.
      Buckle up.
      For the past few years, Hydrogen Fuelcell technology has been making the news in regards to personal transportation. Regardless of how long fuel cell technology has been used in the space industry, the media treated it like a futuristic Godsend for personal vehicles. I recall there being plans drawn up for refueling stations in California, even. But the Bear State is fond of making whatever promise they can to skim as much money from its people.
      See the High Speed rail fiasco.
      When I first heard of hydrogen fuel cells being used in vehicles, I was too young and immature to have much of an opinion. Back then, I was still cruising around downtown and hanging out with Sturgeon to care about motor vehicle trends. Those nights were spent talking trash about HK products, doing blow through rolled up Benjamins, and dozens of questionably legal Polynesian women.
      I'll be approaching this issue regards to efficiency, safety, production, and storage of many elements. We'll first discuss what hydrogen is.

      The Wiki gives a ton of great information. Most of you will know the basics. It's a gas at STP, contains a single valence electron in it's 1s shell (“shell” or cloud of probability derived by shrodinger's blah blah blah Physical Chemistry nonsense, don't make me do that derivation again). It was first artificially made by a guy named Cavendish, and is found naturally as a diatomic molecule.
      This diatomic molecule also really likes to explode if it gets near an energy source. H2 combustion is well documented, and releases 286 kJ/Mol.
      In fact, it can undergo combustion at as low as 4% concentration with air. That's low.
      Hydrogen's low molecular weight makes it the lightest gas around. This was capitalized during the second to last turn of the century, where mighty Zeppelins pushed through the sky like herds of giant sky manatees.

      Large enough to fit Colli-man's collection of miss-matched socks
      Germany loved these guys, and for a while they were all the rage in luxurious travel. Indeed, it was certainly the 20th century now! We had Airships, the Haber Process that was fueling an industrial revolution, and all of physics was completely solved! Thanks, Maxwell!
      (And then came the ultraviolet catastrophe, but that's another topic.)
      However, I mentioned above that hydrogen is extremely flammable at even very low concentrations within air. This fact really sunk the airship industry with a certain spectacular disaster.

      German Engineering, or Masonic Zion plot?
      It's easy to skip over this picture entirely. We've all seen it so many times (Unless you're one of my tutoring students, who look at me like I've got two heads when I mention it. “The hinda-what?”).
      But, this was the end of an era. Static charges ignited the hydrogen sacks that kept the big rigid frame afloat. And though we could have used Helium, a much more stable gas, the damage was done. No one would step foot near a rigid airship again.
      (Also our world's supply of Helium is finite and diminishing very very quickly. It would be wasted in airships. But again, another topic another time)
      Let's get back to the Hydrogen Fuelcell. What exactly is it, and how does it work?
      The basic model is shown below.

      This diagram is for a Proton Exchange Fuel Cell. The proton here is simply a hydrogen that's been stripped of its single electron. A fuel cell works by having very special membranes carefully constructed to permit the passage of a positively charged ion, but not the negatively charged electron. This travels through another path, leading to a voltage across the cell. This voltage can be used to power any electrical device.
      This is an oversimplification of how the device works, but it's a start.
      The benefits of such a device include the shear efficiency that it can have. When properly insulated and owing to proper low-resistance connections, these devices are pushing out efficiencies twice that of internal combustion engines. Which, despite what many places attempt to sell you, are actually quite thermodynamically efficient. These proton based fuel cells have great cold-start characteristics and energy density. Their outputs can actually be very high.
      Indeed, these fuel cells are efficient at all power outputs as well. Their efficiency does not vary with flow of fuel source either.
      Their temperatures can be as low as 80 degrees C. However, usually they are kept above 100 degrees C because steam is far more manageable than liquid water byproduct.
      So with all of this information, you're probably wondering why haven't we started putting these into all sorts of places. This post is about personal vehicles, however, and I'll get right back to that.
      No. I disagree completely with them being used in personal vehicles.
      While I love fuel cells as a power device, their use in personal vehicles is greatly limited. One of the biggest engineering hurdles is the flammability and storage of pure hydrogen. Since hydrogen has such a low molecular weight, to obtain a large enough amount to power a personal vehicle would require a very high pressure container. If you remember back to your Chemistry classes in high school, you may remember the Ideal Gas Equation. Hydrogen is pretty close to an Ideal Gas. As close as you'll get, really. The Ideal Gas Law, in actual use, is only about 84% accurate when used to guess thermodynamic systems. For hydrogen it's much higher.
      PV=nRT, where n is the number of moles. Keeping everything but Pressure and number of moles the same, to increase the number of moles directly increases the pressure. And H2, having a molecular weight of 2 Grams per Mole, would require a ton of moles to get a decent amount of the gas.
      A very high pressure container of pure hydrogen gas in a vehicle that routinely travels at 70 mph. Which is statistically guaranteed to be in an accident in its lifespan.
      The Germans are watching this and going “Nein Nein Nein!”
      According to this nifty search, over 3,000 people die per day in the US due to vehicular collisions. Ouch. 
      However, this issue is the first to be solved. The introduction of Metal Hydrides have solved the storage issues. Metal Hydrides act as chemical sponges for Hydrogen gas (H2), binding the molecules inside their chemical structure. These metal hydrides are usually used as powders, where the hydrogen is then pushed through to store. To release the hydrogen, the metal hydride must be heated. The rate of diffusion is directly related to the temperature at which the metal hydride is heated, and thus the fuel rate into the fuel cell can be varied by varying the temperature of the metal hydride.
      Metal hydrides can absorb 2 to 10% H2 usually, but better compounds are being produced to increase the number.
      This is good, because it gives us a safe way to store hydrogen gas for fuel cells.
      This is bad, because the fuel delivery rate is much lower, and metal hydride fuel cells are, at their very best, 1/4th as powerful as their PEM brothers. At worst, they are 1/50th.
      But this is the best we can do in a vehicle. No one wants pressurized hydrogen canisters on the highways. Hell, most of the time you need special clearance and big signs to transport the stuff. And imagine the safety concerns for the EMTs and Paramedics during a car crash. Even if the tank isn't ruptured, no EMT or Paramedic would risk their lives until the wreckage was cleared.
      When I was going through my EMT training, they made it very clear that it doesn't matter if people are bleeding out in front of you. If you go in while it's still dangerous, you're only being a liability to your fellow EMTs, Firefighters, and police.
      But let's ignore the low power outputs of these MH Fuel Cells. What other issues do we have?
      Well, the fuel cell itself must be created using some very interesting techniques and materials. The biggest expense would be the platinum. Other catalysts are needed as well. As well as a very special proton-permeable membrane.
      To function, the membrane must conduct hydrogen ions (protons) but not electrons as this would in effect "short circuit" the fuel cell. The membrane must also not allow either gas to pass to the other side of the cell, a problem known as gas crossover. Finally, the membrane must be resistant to the reducing environment at the cathode as well as the harsh oxidative environment at the anode.
      This system includes electrodes, electrolyte, catalyst, and a porous gas diffusion layer. The rate of reaction will be dependent also on how quickly the water vapor product can diffuse through the porous material and out of the system. A system can have a lowered efficiency if the fuel cell is too dry or too wet. A balance must be met.
      And while yes, all of these situations can be worked around, it all comes at a heavy price. Currently we are using 30 grams of platinum in vehicle sized PEM fuel cells. This number will be going down once different catalysts are created, but the cost of these vehicles still pushes up to $50,000. The cost will go down, like any technology.
      I've yet to speak about where we obtain this hydrogen gas from. The easiest way to obtain hydrogen gas is via the electrolysis of water. H20 + An Electric Current → H2 + O2, essentially (it's not balanced, I know this.)
      But that electric current must be created as well. This usually comes from the electric grid, which is still, depending on the state, a majority coal-burning.
      Natural Gas reformation is another way to obtain Hydrogen gas, and is the most common way we currently use. It's the cheapest as well. Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.
      The other common ways are via fermentation of biofuel stocks (which is a long process without a great yield) or liquid reforming, which is really unfeasible in large quantities.
      The only way to obtain large amounts of hydrogen is via natural gas reformation, and that's still technically a fossil fuel source. So why were we going with hydrogen fuel cells again? To rid ourselves of dirty, dirty fossil fuel? Well shit.
      So to sum this up, the only way to safely use hydrogen as a fuel source in a moving vehicle would be by using metal hydrides, which require energy to access the stored hydrogen. This stored hydrogen flow rate is lower than standard PEMs, and results in a lower voltage, which in turn leads to a lower power output for the vehicle. More research and development must be done to find proper catalysts that can be made at a low cost, and production methods must be worked out to create the membranes more cheaply. All of this is held up by our hydrogen production systems.
      PEM fuel cell technology is awesome and I love it to death in many many situations. But vehicles isn't one of them.
      I may read about more advances in the near future that would change my opinion completely, but I would be surprised.
      Below I've added a problem out of my heat and mass transfer book (Incropera, 7th edition).

      Even though I'm relatively new to this forum, it did not take long at all for me to notice that here, I am in the company of many fellow petrolheads.
      Documenting the mildly interesting machines I encounter in my everyday life is something I like very much, and since I didn't see anyone here posting much about car spotting, I thought I'd make my own thread. So, if you have any pictures of interesting automotive finds, feel free to share them all right here. 
      To get the ball rolling, here's an imperfect (that racing seat looked really out of place, and there were some visible paint scratches) but still exquisite first-generation Mercury Cougar which I encountered this summer:
