Just try to placate them and move on. If you can figure a way to get a giggle out of it.... bonus points.

Horsepower by itself also doesn't tell the whole story but if you try to accelerate very hard you will always be around the RPM of maximum horsepower.

If they're car guys, I'll tell them what the actual hp and torque is with a list of the mods that got me there, but regular non-car people... I stick with the above line. =] Usually works really well.

The best way to describe the power characteristics of a car would be to show an acceleration curve from a rolling start thorugh all gears until top speed. That would compensate for all kinds of variables such as weigth, drag, grip, gearing +++.

Should be a simple thing to do in 2014...

Assuming both of the engines (below) are swapped into the same car, and torque is flat:

A 150 foot pound engine which can spin to 8500 RPM, is better than 200 foot pound engine which hits the rev limiter at 4500 RPMs. Torque alone is not the full picture.

Math is a bit off...

2000lbs @ 300hp = 6.67 lb/hp

That's the same as:

2500lbs @ 375hp

3000lbs @ 450hp

3500lbs @ 525hp

4000lbs @ 600hp

4500lbs @

...

also the engineer in me cant go without pointing out the semantics. Horse power is a unit of power not work. Work is synonymous with energy. Power is the rate of work flow.

If you integrate, or add up over time, hp you end up with work done. In they end power is what makes cars fast, provided it can be geared appropriatly.

Right. "beat" as in faster 0-60 / 1/4 mile vs a heavier higher hp car. Wasn't making a presentation up and down the scale.Math is a bit off...

2000lbs @ 300hp = 6.67 lb/hp

That's the same as:

2500lbs @ 375hp

3000lbs @ 450hp

3500lbs @ 525hp

4000lbs @ 600hp

4500lbs @675hp

...

But here is a nice semi accurate comparison (without scaling to a precise decibel point)

I believe i read the Evora is 8.7 hp/weight comparison?:

A new corvette (3500lbs) think i read 5-ish per pound?

A newer Mustang (3600lbs?) maybe almost 7-ish per pound?

Thus a corvette blows the doors off an Evora S (350hp/3200lbs) 0-60 and 1/4 mile on acceleration

A Mustang eats its lunch too.

Without to much argument, the Evora needs a bit more kick, 400hp would be nice in the acceleration dept.

and im still wondering why my Evora window wiper switch seems to have a rear window wiper control (is that what it is?), can seem to find the wiper. anic:

Which brings us back to post #1HP = Torque x RPM ÷ 5252

HP dictates how fast you hit the wall.Which brings us back to post #1

Torque dictates how hard you hit the wall.

In other words:HP dictates how fast you hit the wall.

Torque dictates how hard you hit the wall.
