Is the roadholding index from 0-1?

I don't know. I'm gonna guess that the "roadholding index" is the same as lateral acceleration (how "tight" a car can turn, or how fast it can corner at a given speed), which is measured in g's. In which case the limit is something bigger than 1. Magazines such as Road and Track will list the lateral acceleration of the cars they test.

So I'm going to, then, focus on comparable accelerations, and look best at stuff with higher or equivalent horsepower and torque.

Also look at the weight of the vehicles. If your Jetta is lighter than Comparison Car A, but everything else is exactly the same, your Jetta would have more pep. Of course this is assuming the Jetta is functioning within generally accepted parameters, since it has been in service for a bit. A new car off the lot is always going to feel peppier than a car that's got 10-20K miles on it.

edited to delete extra consonants. I don't like the keyboard on my work computer anymore.

my chair has no torque. mostly because it has a broken foot. I do have a new keyboard, because the broken foot caused me to spill tea all over my keyboard.

I would have liked to drag race Hank in my highschool ride which was a 1983 diesel suburban.

Also, torque is generally measured at the engine. Torque at the drive wheels is greater, due to the gearing of the transmission and differential/transaxle. Off-road trucks and rock-climbing custom trucks will have ultra-low gearing, so they can produce thousands or tens of thousands of lb/ft of torque.

Crap.

I am guessing Tom is talking about baseball, not torque.

t Waits for Teppy to come dancing back into the thread.

oh, I shouldn't have cheered. cheering throws them off.

The diesel would probably have won. Hank is slow and steady. Seems diesels, at least newish diesels, go much faster. But then I don't know much about them.
