The curb weight for an 82 camaro is about 3192 pounds, versus a Yaris's, what, 2300 pounds?

The horsepower to weight ratio of the Yaris is 0.046 and for the Camaro it's 0.051. The Yaris probably has a much lower drag coefficient than the more boxy Camaro.

So it's not surprising that the Yaris could compete with an 82 Camaro.

The weight-to-power ratio would have to be about the same in order for performance to be about the same.

The Z28 Camaro in that road test was fitted with the optional "crossfire injection" engine that was rated @ 165 SAE Net HP - but could only be had with a power sapping automatic.

The base engine cars were rates @ 145 HP, but could be had with the 5 speed manual trans, which also reduced weight a bit.

I just think it's interesting that a 1.5 liter economy car (Yaris) that some people might label as "slow" is actually every bit as quick as some 5.0 liter V8 performance cars from the early 1980s.

I'm old enough to have driven those Z28 Camaros back when they were new, and did in fact drive MANY of them. My Yaris is certainly every bit as quick, though the my Yaris has stronger brakes. Of course, the Z28's high speed stability was vastly superior to that of my TRD suspended Yaris, but that's another story.
