Lol, am i dreaming or did the technician at CITA really state that fuel type would have an effect on HP and TQ during the test? I'm flabbergasted. Really. The only change between two fuels would have been the amount of fuel consumed during the test. Instead of doing a fuel economy test in a calculated environment (the dyno at CITA), they got a 50 year old guy with spiked hair who puts 87 octane in his 15k Corvette to do a fuel economy test in an uncontrolled environment.
A car will require the same power to travel x distance (all factors equal) regardless of the type of fuel used. For power and HP figures to change with the same motor you'd have to change friction sources such as aerodynamics, tire pressure, mechanical losses, or weight, etc. I still can't believe how bad that test was. Even when they say the pollution test was worse with premium we can't see roughly the same values on screen for both tests.
This report is almost as bad as the idiots at TVA doing 70kmh in the Ville-Marie tunnel trying to prove that people drive too fast...
