I understand what you're saying....just want to make sure everyone understands that power on the low end isn't necessarily lost. Cubic inches and turbo or super will give more torque at the cost of gas.

BTW I'd rather see a T-Rex in my garage than a souped up Yaris....it may get better milage!

The ZPI Turbo kit said it actually increased MPG by 2-3MPG, but you must use high octane fuel, so it all evens out. Now if you go stompin' the gas everywhere you will probably get no better than 30MPG... probably a lot less.

WTF are you guys talking about lack of low end power?

First, there is no stock chart to compare these numbers to so it shouldnt even be discussed.

Second, The dyno chart shows the car has 90% or more of its peak torque from 2000 to 5000 RPM. What more do you want??? That is a pretty broad powerband for a little motor.


Look and the numbers compared to the Fit. The Yaris hits peak torque at about 4000 RPM, the Fit 5000. The Fit started out at a higher RPM and still looks like it had NOTHING on the bottom end. It is just starting to wake up at 3000.
