Horsepower is a definition of the amount of work. Torque provides the ability to do it. Common sense is that claimed horsepower by all manufacturers is just a general reference at best today.

My 9 liter diesel truck engine had less claimed horsepower. I do not remember accurately but 135-150-165 was the range. Certainly no more. Yet could easily tow far more of a load that any domestic car type vehicle could ever handle.

It had much higher torque. Than any they could produce was the reason. For example I would guess that vehicle Tom has needs only about 12 real horsepower at the wheels to maintain 50 miles per hour.

My heavy truck was far far heavier than any car type vehicle. Or pickup.
Even with very poor aerodynamic performance. Yet add a ten ton load as well. I could stay with traffic fairly easily. Even go faster if I wanted to. Modest grades never slowed me. Real signifigant grades took their toll to some extent. If I had a heavier load.

How much horsepower do you think electric cars have? The electric motor produces maximum and sustained torque even as it initially starts to rotate.

That is why some of those electric cars can do 0-60 very very quickly in comparison to gas cars with two hundred claimed horsepower. Or far greater. I suspect the horsepower rating on those electric car motors is perhaps around twenty but do not know. What I do know almost for certain. It has got to be less than fifty. They do not really need transmissions normally as we understand them. Because of their ability to supply pretty much heavy maximum torque at any motor rpms they produce.

Getting back to true horsepower ratings. Plus torque relationships. Convention and it is convention. If you want to replace a true fossil fuel engine. Lets say of ten horsepower driving an air compressor. You replace it with a five horsepower electric motor. The compressor will operate just as well or better. Dyno meter testing would indicate both horsepower claims on the two where valid. One was ten horsepower and the other five.

Just not an electric motor rated under the fraud of the modern rating method they use. The ratings system of electric motors was changed for consumer versions. By calculating them in a stalled condition. A marketing ploy that one has to be aware of. A motor is of no use to you if the quoted power you need is only there when the motor is bogged down. Today a consumer electric compressor rated at five horsepower would be a 2 to 3 hp commercial one.

I think I could give a lot more examples. My posts at times just are a little much as they are. I could have just posted torque rules.

Horse power looks at a load. Torque amount available determines if it can be used for the load. Twisting force in the case of engines. I tend to look at things in a somewhat abstract way. at times.

If by the seat of your pants a vehicle feels powerful. It probably is.

Thanks Barry!

The filler for adblue is in a really stupid place inside the spare tire. Most inconvenient!

I'm wondering...I heard there are pumps now where you can get it like gas. Wondering about voiding the warrenty if there are types that are not approved by VW.

I even have seen the stuff on sale from time to time. So it has to be easy to source. It is sold by the container here .Not really expensive either.

Not a dealer only item I suspect. Ask the local dealer if they are product specific. You never ever want to give that particular company an edge. To deny warranty.
