On the highway, I was between 70 and 80 mph when not confined by traffic.

The result was that my mpg went up from 18 at the start to 20+ by the end. This rivals my 2010 SS, the difference being that the ZL1 has 650 hp vs the SS's 400 hp.

So what exactly is the gas guzzler tax for?

My 16 4Runner has never gotten better than 19mpg on highway road trips and I've always driven it like a grandpa.

I won't go into the political aspects either, but the fact is that anything with a fuel economy below 22.5 mpg is a "guzzler" according to the federal government: https://www.ecfr.gov/current/title-4...ion-600.513-08

This only applies to passenger cars, so that 4Runner of yours and all its SUV/truck kinfolk can suck down as much they want and you still won't pay this tax.

My SS, far beyond stock ZL1 power, gets 25-26 mpg on the highway
