When talking about diesel engines, you've gotta give the lb-ft TORQUE! These trucks use high torque to carry these big loads, not horsepower. Drives us, already neurotic, mechanical engineers nuts!
It is the engines capability to produce “work” that carries big loads. The amount of work an engine is capable of is measured in kW or bhp. A high torque rating over a wide band of engine speed is nice to have, but in the end you can get around low torque with low gearing. You can’t use gearing to get around a low power rating (kW/bhp). I’m not sure you are a mechanical engineer...
@@AndreasBrOlesen Wow way to overanalyze one sentence. You realize this is RU-vid, not an ASME forum. He's talking about big diesel engines and only quoting horsepower rating, not torque. Since torque output is much higher than HP in diesel engines. I just wanted to know the torque rating of the engines. I wasn't writing a thesis on the topic! Why are you suddenly bringing up gearing like nobody knows how the powertrain works. And yes, I am a mechanical engineer and you sound like some freshman in college lvl knowledge who just passed thermo and thinks they're the smartest person in the world. I took a break from actual engineering work to get on RU-vid to find your pompous self.
@@J_McPhearsom Wow relax dude. You simple made an incorrect statement in your original comment "trucks use high torque to carry big loads". Then you state that it drives you mechanical engineers nuts, but why would it when the statement is wrong. To have an engine do work, yes you need torque if you want the work to be done at idle engine speeds, you need a lots of torque! but it is still the engines power rating that dictates how much work the engine is capable of producing. If you really want to analyse the engines power characteristics, you really need a complete power and torque curve anyway. Theres a reason why the power rating of a truck/tractor is often part of the model name, not the torque rating.
@@AndreasBrOlesen I was generalizing that the high torque generated by the engine (yes at low rpm) is responsible for the work (ft-lb) needed to move such heavy vehicles and loads. I refrained from specific terms like 'work' since my assumption is most ppl aren't engineers. What peaked my interest are these large diesel engines, optimized for these applications and duty cycles. And yes if I really wanted to know, best to look the HP, TQ curves. To me, the narrator seems to be mentioning these mechanical specs without understanding.
As a German, you get absolute gasps. It is not called Merceidis but Merceedes. Also MAN is not pronounced MEN but M...A...N the reason is that it is called Maschinenbau from Nuremberg.
he doesn't spell it wrong... or are you spell DAF, FIAT or SEAT in the same way? No.... but DAF and the rest are not words, they are also shortcuts like MAN....or like normal people say - Man (and yes, BMW you cannot spell as a one word...well maybe in welsch its possible, but what I know)
What about the Renault/ Mack defense Armoured Kerax 8x8, Mercedes Defence armoured Actros 8x8, Oshkosh Defense Global HET/ M1070A1 HET, Oshkosh Defense PLS, Oshkosh Defense HEMTT ? They all above the $175 000.
I'm Australia so I have no bias towards any of these trucks, how ever I see a common issue across all of them, there no under body protection which going of current datat by 2021 should be by default, an absolute must!! Aside from that all of them look like they would do the job, it would come down to reliability, repair accessibility, parts availability and in general ease of maintenance.
Funny that the US bought that shit box off the shelf commercial truck from International. That thing looked like it was about to shake itself to bits. Likely, they just went to uhaul, bought some old stock, painted them tan and sold them to the government for 300k each.
@@walther2492 if you showcased MAN & Zetros as military vehicle, then Arocs also have made for military purpose. I hav driven one already in 8x8 configuration. So this comment make sense.
Why do the Navistar trucks cost soo much? I have always been an huge fan of IHC, but damn! Somebody took advantage of a US military contract. Maybe the US should go foreign for any trucks we carry contracts for.
America needs to STOP going foreign for Anything that we can produce. America needs to hit foreign importers with huge import taxes like other countries do to us. America needs to give companies incentives and tax breaks for keeping companies in America, or bringing them here. All this bullshit importing and outsourcing is Destroying America. We used to make it all, we can do it again. Eff joe biden, his DemoNcrat CoWhores, and Everyday who voted for that RACIST Tyrannical Traitor
Truth be told I’d rather have, if I had the money would be a Russian truck and here’s the reason why. They’re not the best looking trucks, because they were never meant to be but they’re cheap, extremely reliable and with very little maintenance they’ll run forever and my favourite Russian trucks are the Uralic and the kraz
MZKT 7930 $320K should be the winner among others competitions. Navistar 7000 series, $350 is among the losers because over priced and simple design. Tatrapan 8x8 should be second winner for multiple games changers, because the $360K.
6 minutes in,,,,,,,,, and already at 3 advert breaks,,,,,,,,,,,,,,,,,,,,,,,,,,,,, why does every fucking video have advetrts;;;;;;;; there should be an option, of no adverts very friggin frustrating
In this case, the mercedes is cheaper because it is not a custom-made military product and is produced in large series. the Zetros is a truck that is often seen in normal road traffic by construction companies or shipping companies
