I'd be more impressed if they locked them in gear at 2000 rpms and see which one holds speed better going up an incline.
There is no engine in any truck I've seen TFL test that runs 2,000RPM up the IG. Even the big diesel engines are even running 3,000+ RPM going up that long, steep grade.
Why? Because they run a real performance test. They attempt to run at the speed limit over the entire run, use tow haul mode when available, hold full throttle the entire run if needed, and almost NEVER interfere with the trucks systems. They run hard and let the truck do all the "thinking" as designed.
I thought the run was cool to see. A lower power turbo motor, and a higher power naturally aspirated engine. Both at full power on an incline, at high altitude. All this proved was the turbo engine lost less power at altitude, and the big V8 had only enough loss to then equal the turbo motor power output. This is not one bit surprising.
