Alright my friend is looking for a toy hauler so we were trying to find something that got decent mpg, could haul 8 people, and a boat if needed. Now where trying to fill out the Calc:
Aerodynamic & rolling resistance, power & MPG calculator - EcoModder.com
Given: http://media.caranddriver.com/files/...-ltz-specs.pdf
And we are starting to realize the Tahoe must be super efficient to be a long tail model and get the mpg its rated for.
And it really does it has cylinder deact. and it functions pretty well. Sometimes I've seen people avg 22-25 mpg on the free way unloaded.
Given:
Vehicle Weight: 5840
Cd:0.36
A:37.3
Tire: 275/55-20 @ 35 psi
old EPA: 16/22
new EPA:14/20
So what values do you think we need for:
CRR?
Eng Eff:
Dt Eff:
Load:
What is the mpg highway peak and average speed for their test?
