At AT sedan with P185/60/15 tires, the standard 4.29:1 final drive, and the standard 0.7:1 4th gear overdrive ratio, turns right at 3400 RPM at 80 mph. Which is still pretty low for a little 1.5L engine. Even the monster 500 cubic inch push rod V8 in the 1976 Cadillac from America's glory days turned 2700 RPM at 80 MPH. That's only 20% lower than the Yaris.

Even more impressive, when called upon, the Yaris' little 1.5L produces over half the power that the old 500 (8.2L) could. That's over 3x the power per litre displacement... and without any sort of turbocharging.
