Power or Torque? Which is better to have? We discuss what is better: big Horsepower numbers or good low-end Torque figures, what sells cars & bikes and what win races, why high Torque engines accelerate faster and why high Power engines have higher top speed. Also we'll look at the easiest analogy, which'll help to understand engine Power and engine Torque!

A little info about me. My name is Andrei Bodrov, originally I'm from Moscow, Russia, and now I live in Buenos Aires, Argentina. Back in Moscow I was a motorcycle instructor and creator of Moto Control Beginner & Advanced motorcycle rider courses, which quickly became the most popular courses in Moscow (well, at least the advanced one😁). My advanced training course makes emphasis on slow speed riding techniques at first (such as good clutch and throttle control, proper riding posture, proper use of vision, etc.), then proceeds to more advanced techniques (such as aggressive braking, trail braking, maximal lean angle). The course incorporates a lot of exercises from DOSAF slow speed riding (similar to police rodeo like motorcycle training in USA), braking and cornering exercises and motogymkhana style riding. And now, since I actively learn English - I decided to post some useful videos for both your and mine practice!😉

Amazing video, majority of hp vs torque videos are pretty bad but this one is very good. Also one more thing i would like to add, as far as american v8s go yes they have much higher displacement than european dohc engines HOWEVER because they are OHV and not dohc they are still lighter and smaller than european v8s. They can also be great performers. Take GM LS3 and Bmw S65. Ls3 has 6.2L displacement compared to 4l of s65 but ls3 is physically smaller and lighter than the s65 despite having more than 1.5 times the displacement thanks to its very compact ohv valvetrain heads compared to the absolutely massive dohc heads of the s65. Yes because its ohv it cant rev crazy 8500rpm as s65 but that doesnt matter because of its huge displacement and its big torque it makes peak 430hp @ 5900 rpm meanwhile s65 makes peak 414hp @ 8300. s65 is a less powerful and much much less torquey engine yet its also physically heavier and bigger than the "big inefficient american v8". Since LS is comfortably making that power its also way more reliable than the s65 thats pushing itself to limit to get that power. My point is that american v8s make a lot of sense performance wise, i am not into bikes that much so i cant speak for harley idk about those but as far as car engines go the american v8s are very good for prrformance also. The only downside of ls3 compared to s65 is worse fuel efficiency and emissions and outside of that it destroys s65 in everywhere else especially in reliability. Also just in case anybody doesnt know , ls3 and s65 are both from same mid to late 2000s era and naturally aspirated and used in high performance cars. S65 in e90-92 m3 and ls3 in the base version c6 corvette and later in the camaros etc as well. Base C6 Corvette destroys the m3 as well

Very well done, as usual, Andrei. You're the first one that really put the torque & power matter in clear terms. Also, the choice of images is very good. We can feel how much effort you put on your videos and how much passion you have on teaching people. And, if everything above isn't enough to prove someone that your channel a very enjoyable one, I must add that you also have a very good sense of humor and have a charismatic aproach. As a Harley rider, I must say that, as I open the throttle, the feeling of low end torque pulling like a freight train has no parallel. Congrats from Brazil. Hope you're enjoying your Latin America experience.✌

Hp puts you in the wall, torque determines how far you go thru that wall. And as the gearbox is merely a torque converter, then 1st gear is he most powerful.

Hi Andrei, I have a video idea for you, about ABS: When talking about ABS, a lot of riders say they don't want it because they are so good at braking, they can stop faster without ABS. How true is that? I think they over-estimate their abilities. I believe that with early ABS, an expert rider could out-brake it in ideal conditions. However, I doubt that the average rider could out-brake modern ABS. A related question: Is there a difference in stopping distance between slamming on the brake with ABS (so that the ABS kicks in straight away), and progressive braking with ABS (that is, using proper braking technique)?

@MotoControlEn Жыл бұрын

Hi! In my opinion for road bikes ABS is always good, because even if you trained braking a lot you'll still have to do that in rain, sandy, muddy asphalt, etc. It's very hard to train in ALL surfaces, so ABS is good. For racing, gymkhana, and stuff like that I don't think ABS is necessary. Can we out-brake ABS? Of course, we did it all the time on our courses. On the same patch of asphalt in a very good weather😁 On newer top-class bikes the difference is within the measuring error though (not only because of newer ABS systems, but because of advanced suspension too, which reacts much better on ABS "chattering"). For real-world application at random pavement at random weather however ABS is always a good safety feature. And about slamming brakes - on older/cheaper bikes yes, the difference is pretty significant, like about 10-15%, on something new and cool like BMW R1250 the difference is maybe 5%, which I consider within the error (we didn't use any advance measuring methods, we just had an entry gate and the points where the bike stopped in multiple tries, plus the rider error on entry speed, so take our results with a pinch of salt). That's if we just slam the brake vs progressive braking technique, we don't consider massive errors like trying to brake on opened throttle or death grip on the handlebars, even the new bikes don't handle that very well. They won't fall down, but the stopping distance will be much bigger.

@dgphi Жыл бұрын

@@MotoControlEn Thanks for your detailed response! I appreciate that you have tested these things out in reality. Another reason I think that ABS is good for everyday riding is that sometimes things can happen so suddenly (such as a car pulling out on us) that we don't have time to consciously react. We just brake instinctively, and good braking technique can go out the window. If we are being realistic, we don't know how we will react in a panic situation. Training is helpful, but unfortunately it's hard to train for unexpected situations. Another good thing about ABS is that it's a good training tool, especially for new riders because it allows them to practice hard braking in a safe way. A lot of people crash because they don't brake hard enough because they don't know what maximal braking feels like.

With regards to bikes: is it common that 2-cylinder mid-size engines (like 400cc) are less prone to stall in low rpm than 1-cylinder engines of the same power (similar motorbikes) - kind of more forgiving for inexperienced riders?

@MotoControlEn Жыл бұрын

Hi! Yes, some bikes are more prone to stall than others, and the amount of cylinders is not the only thing that matters, the gearing and fueling have big impact on that too.

It's piston engines you are talking about, not "internal combustion engines", as "internal combustion engines" are very different - piston, gas-turbine, rocket engines. 0:10 "complicated formula" is P=M*rpm. Is it really that complicated? The formula is self-explanatory.

@288gto7 Жыл бұрын

I still dont understand why higher wheel torque accelerates the car faster in lower gear. The hp at the wheels is nearly identical at every gear but you accelerate much faster in first gear due to the higher wheel torque in first gear. Why is engine hp best for acceleration but at the same time max wheel torque is better for acceleration

@LukeTheRager Жыл бұрын

Transmission changes rpms at the crank to different rpm at the wheel. For example if your gear ratio for first gear was 0.5 at 1000 crank rpm, your wheels are rotating at 500 rpm. The power is not changed (if you ignore transmission losses), therefore you essentially doubled your torque at the wheels.

@288gto7 Жыл бұрын

@@LukeTheRager yes thats what im saying you get higher wheel torque at low gear and higher acceleration so my question is if wheel torque is what accelerates us , then why do we even care about engine horsepower? Shouldnt we get peak acceleration at lowest gear and at peak engine torque because that way we will have highest wheel torque going to the ground

for practical everyday usage (no track days): You want the most torque, because this gives you best acceleration. You do not want high hp, because this gives you opportunities for costly speeding tickets. Only those imagining themselves to be aspiring MotoGP heroes really need high-revving engines 🤣😂. Just as an example my Kawasaki revs to 12000 rpm, but where I live I can rarely exceed 6000 rpms.
