Yeah but they still quote horsepower alongside it because people like the sound of it. I remember when FPV proudly announced one of their XR6T models as having 432 horsepower.
Yeah, also TV sizes are in centimeters... I agree that som measurements make sense in imperial when less precision is required, like inches for wheels and screens etc. However it's still weird that tires are in millimeters. At least having one measurement system within the same component/system would reduce some confusion.
@@cjansson Cross-ply tyres are measured in inches, radials had to be metricated to avoid confusion, even in America. As for tellies, I bought mine specifically because it was advertised as "55 inches", have no clue what that is in cm.
@J B tires are weird though because height is usually inches and width is mm... think 345 wide tires but they are on 20 inch rims? Oh and off road tires are 35s or 37s? I will never understand
Most of Europe also requires kW alongside the (optional) PS. People are used to the latter so it's what advertised. To add to confusion it doesn't say PS but is instead translated into local languages. Incidentally where I'm from this translates into KM. And of course we also use km for kilometer. Fun!

What i like about using horsepower is that knowing peak power and torque tells me something about an engine. For example, if an engine makes 500 lb ft of torque but only 250 hp then I know that it's a monster up to like 2500 hundred rpm but then dies like it's been shot in the back. LIkewise if an engine only makes 150 lb ft of torque but has 300 hp I know that it has a high redline and that you'll have to use it to go fast. Because 5252 is always the denominator once I have the power and torque figures I will always have an idea about how an engine does above and below that line.
Yeah, we've towed Boeings around with engines that output 140HP and 270 ft*lbs. A 140 HP engine that outputs 80 ft*lbs isn't towing much bigger than a Malibu Barbie trailer.
Weirdly enough, EV manufacturers, even the new ones like Lucid, Tesla etc use horsepower on their websites, not kilowatts. Deiter isn't going anywhere, I guess.
@@pigeonpoo1823 Exactly. It is all for comparison sake. Units don't really matter as long as you can compare one to the other without the annoyance of conversion.
They have show horsepower otherwise it is hard for the average consumer to compare their cars to others, but I agree that all car companies should rate their cars in kilowatts alongside horsepower.
In the EU all cars sold have their power rated in kilowatts (for both EVs and other powertrains). I believe this is by law. They also usually have the power rated in horsepower within parentheses, but I don't think that's required.
Excellent video. There is of course a better unit: the Hairdryer (HD). Conversion is easy: first convert your car's HP into watts, then check your wife's hair dryer (or your own, I don't judge) for wattage, then divide the car's power with the hairdryer's power and now you have your car's power in HDs. I'm sure this will catch on and people will stop looking at me funny.
To clarify at 3:23 a "modern" turbocharged car will be quicker around town, not the old school turbo which has lag for days.But damn the amount of knowledge this guy has.
Slight correction, work isn’t measured in torque it is measured in torque times the number of revolutions. Otherwise a really informative and entertaining video as always, keep it up Jason!
I assumed this would be the top comment. As a pedantic nerd, I twitched when he said torque is work and immediately came to the comments to be sure it had been dealt with. The important distinction between force and work is that force can be applied against something that doesn't move. If it doesn't move, no work is being done. This is why we think of low rpm torque when towing because the higher force needed to move a static heavy object is one of the key attributes of a tow vehicle. Sometimes people confuse torque for work because of the units (pound-foot, newton-meter, stone-horse, etc) since they involve a distance (which is just the lever arm length, not an indication of work), but I think Jason simply mis-spoke here.
Are you guys sure about the tazing part? I was under the impression that this was the work a horse was regularly expected to produce in a steady state. I'd imagine a tazed horse could easily produce 15-20+ horsepower in that first second. 150lb Cycling sprinters make 2+ horsepower for like 30-45 seconds at the end of a 200 mile race. Ya'll selling the poor horse short.
I think it can be asserted that James Watt was not in the posession of the technology to make a tazer, much less a hand held one he could or would use on a horse. (or he would have ended like the guy in the video who tried to hit the horse...)
Yeh, it was a horse working all day at that rate. Just like you'd be able to work harder in brief spurts if your life depended on it, vs. slogging through an 8-hr day, so can a horse easily make far more than 1HP in maximal exertion (IIRC, around a dozen HP peak). A strong man can output 1HP briefly. (Like a weightlifter benching 275#, two feet upwards.)
I have one complaint and that is the lack of actual cold start footage from some epic engines. My favorite is a ford small block. Thanks for the awesome content.
Thier are 3 horsepower ratings a engine gets 1. Gross HP: the HP that an engine produces with only the accessories needed to run, no emission equipment, measured at the rear of the crank. Has been incorrectly interchanged with SAE HP/BHP/PS/Kw 😔 2. SAE HP/BHP/PS/Kw: the power that an engine produces with all accessories, all emission equipment, with an OEM intake/exhaust system for that vehicle at the rear of the crank. Has been incorrectly stated, even currently😔 that SAE HP has a artificially higher HP rating vs BHP, including North American market only vehicles(or Gray Market imported vehicles), even though sense 2006 SAE HP rated engines have had all accessories on the engine. I am not including vehicles that have been altered for different emission/sound decibel/exhaust route changes(what side of the road you drive on) on non North American market vehicles. 3. Wheel(Real) Horse Powers. Includes transmission, diferential(s), wheels/tires , mabye a transfer case, mabye cvj's and mabye a driveshaft(s).
Actually, how I know the story of the horsepower is that, the average weight of a human (male) is 75Kg. So, a horse, carrying an average rider (75Kg) on it's back can jump as high as 1m in the air and it would take 1 sec. to do so. That's how it was decided on the 75Kg-1m- high-in -1 sec. part of the definition of a horsepower. Not sure if it's actually so, but that's the story I've heard.
As a kid I always pictured horsepower in my head as a car being pulled by 300 horses, a real big cloud of dust and clopping hooves as they trip over each other and create general mayhem everywhere I would drive, just like today.
Well considering most household microwaves are around 800W, they have slightly more than 1HP (= ~746W). Also maybe it was just here, but we used to classify AC by their HP, we now use BTU's.
Well, because for A/C HP is how much power they draw, and BTUs are how much cooling they provide. Makes more sense to use the latter, because the former makes no accounting for efficiency.
You need to change to Metric measurement for lenght and to German PS (HP) for power. Japan,UK and US,use BHP. But the other use HP (PS) Imperial: 1mile = 1760yard = 5280foot = 63360inches Metric: 1km = 1000m = 100,000cm = 1,000,000mm Temperature: where's water start to be ice Fahrenheit 32°F Celsius 0°
That’s why the Aussies speak in Kilowatt and Newton Meter. Though when they say it makes 100Kw and it’s a supercharged Holden. That’s like you said about the TRX. The measurements should be equal to what you’re measuring. Kilowatts for EV HP/PS for combustion.
A typical hairdryer is 2 horsepower as it is rated at about 1500 watts ( i watt is 1volt × 1amp) 746 Watts = 1 HP. Work and Torque are defined as ( force) ×( distance) power as ( work / time) and Energy as power × time. If a car ran at 300hp for one hour that is energy . Kiliwatt × hours is how the power companies charge you . A horsepower hour . 1 hp for one hour or 746 kiliwatt hrs
Braking power is also rated in Kilowatts The all time greatest truck EVER, which is the M35A Deuce and a half military 2,5 ton 6X6 truck, has brakes that generate 12KW of power (16 HP) with a GVWR of under 26,001 pounds this allows the M35 to be driven with the need of a CDL.
12 kW sounds a bit low, even if it were per brake. If you take out the air resistance i would say, it still takes the truck longer to reach its highest speed than to brake to a standstill from it's highest speed. So it should generate more braking power than engine power. Wikipedia states the engine to have 95kW...Or were the brakes in the 40's that bad?
I like your videos and most of the time I tend to agree wirh you, but please allow me to disagree with you on one aspect: kW vs HP. In some countries the power of the car is actually given in kW in all specs and brochures. This is because it is a scientific unit (SI): W (Watt). For those who don’t know - and there are those… - 1 kW (kilowatt) is the same as 1000 W (watts), but it would be silly to say that my car generates 150000 Watts. Instead we say it generates 150kW. I know… school stuff, but you’ll be surprised how many people skipped this lesson at school :) Horse power is not a scientific unit but it is quoted everywhere because it looks better. Regardless of whether it is EU or USA or Japan, the horse power figure is always higher and looks better for the marketing guys, so its easier to sell.
The actual engine output measurement I WANT to see is the integral of horsepower between the RPM the engine drops to after a redline upshift, and redline.
1:26 Whoops! The sentence "So we measure work as Torque" is technically wrong because that would mean that The torque *is* the work. Thats an easy mistake to make because, just like Work, torque is defined by Force times length. BUT the length refers to the length of the lever, not the distance. Work is force times distance - In rotation, the torque is the force and rotation is the distance. So in rotation, work is torque times rotation. So power is still work over time. Torque (N*m or lbf*ft) times rotation (revolutions...) over time (...per minute).
Watt actually measured the power produced by ponys pulling loads up from mines. He then assumed a horse should produce 50% more. And this is the very roughly estimated power these animals can produce continuously over a day shift without keeling over. A horse can actually produce over 15 horsepower in short bursts. A human in good shape can also produce over 1 horsepower in short bursts.
My main problem with HP is that it wildly underestimates the wattage of a horse. I believe (with no citations) that it is because they used mining ponies for the test. Given the right equipment (a bicycle) I can produce almost 2 HP very briefly. Top level riders can produce 1/2 to 2/3 of a HP for an hour. Racing driver (and Olympian) Sir Chris Hoy could produce around 3.33 HP when accelerating on his bike. I doubt anyone would argue that I am more powerful than a horse. Let alone 2. And just for you true geeks... using the same level of hand wavy math as Jason did to explain why HP=(TQ*RPM)/5252, a quarter horse running flat out up a 2% grade is producing over a horsepower.
This dude is a pretty damn sharp car journalist.

1:26 Whoops! The sentence "So we measure work as Torque" is technically wrong because that would mean that The torque *is* the work. Thats an easy mistake to make because, just like Work, torque is defined by Force times length. BUT the length refers to the length of the lever, not the distance. Work is force times distance - In rotation, the torque is the force and rotation is the distance. So in rotation, work is torque times rotation. So power is still work over time. Torque (N*m or lbf*ft) times rotation (revolutions...) over time (...per minute).
Jason, what did you do to the stig? I saw his helmet in the background and i am now concerned!
Some hybrids are awesome, or they can be made awesome!
Love our Camry
I had to subscribe after watching this video.
same thing with electronics. I have a 2000 watt blender and it's 1amp. it's like a 1000hp MX5
Bravo!
Watt actually measured the power produced by ponys pulling loads up from mines. He then assumed a horse should produce 50% more.
And this is the very roughly estimated power these animals can produce continuously over a day shift without keeling over. A horse can actually produce over 15 horsepower in short bursts. A human in good shape can also produce over 1 horsepower in short bursts.
Love Jason
Great 👍
This is about the time for merica to switch to metric. No wait that was about 40 years ago.
Yes, using the kilowatts for measuring power is much more suiting with switching on electric power.
Also, when is the review of the Roma coming out?
Right ... kilowatt is energy burned off by electrons flowing thru the conductor. Not an engines rotating force.
@@ACommenterOnUA-cam No, but it's more constant measure than the power of a single horse. Do you think that all horses have same power?
@@Cane306 my comment remains as a FACT ...
My main problem with HP is that it wildly underestimates the wattage of a horse. I believe (with no citations) that it is because they used mining ponies for the test. Given the right equipment (a bicycle) I can produce almost 2 HP very briefly. Top level riders can produce 1/2 to 2/3 of a HP for an hour. Racing driver (and Olympian) Sir Chris Hoy could produce around 3.33 HP when accelerating on his bike.
I doubt anyone would argue that I am more powerful than a horse. Let alone 2.
And just for you true geeks... using the same level of hand wavy math as Jason did to explain why HP=(TQ*RPM)/5252, a quarter horse running flat out up a 2% grade is producing over a horsepower.
The edit is hilarious 😂
Love it

I only use hp because im used to it. Its just hard to compare kW and HP when I've used HP all my life
