Even if the weight to power ratio came out to the same, that is only good for first gear. If even first gear. The gearing of a car, how much resistance you have against the engine (air flow restrictions, rotating mass, gear ratios, etc...) also matter a lot. The yaris does 32 mph in first gear, 61 in second, and close to 90 in third. I haven't removed the limiter yet, so I have no clue where 4th stops, except the whole car tops at 117 (stupid govener). Now, once you take into effect drag coefficients, and weight, and top RPM, and all the other bits, the only real info that counts in the end is the 1/4 mile, 1/2 mile, and 0-60 times. My Yaris is far from stock, and before I had my header on there, I killed my boss's (somewhere around 2000) mustang. It was all stock, and was a 5 gear manual like my Yaris. His car weighed a LOT more, and we were already going about 50. I switched to 2nd (close to top of that gear, and he hit 3rd, and I blew past him, slowing when I got to 80+ mph. He chewed me a new one when he finally got to work later. Then, I've had a civic destroy my car at a light. I wrap around turns though, and everyone hates it when I do that, so I do it all the time. You should hear my wife freak out when she's in the car and I put the car to it's max around a corner. She'll grab the door, the dash, me, EVERYTHING within reach and start yelling like crazy for me to slow down. My car does seem to be suffering here in Colorado though. I have to get the MAP sensor reset. My car is used to 10 ft of elevation, now I'm at 4,700 ft. A little less air up here. But back to the subject... it isn't the BHP, or the weight, or the year... in the end, it's everything all wrapped into one giant number. So, yes, this could go on forever. Everyone should also rip out the smaller of the two air filters in their stock intake. Yes, there are two. The second one is for "blow back" or some junk like that. Take it out and you will see the tach move just a little faster.
