___What you have read is incorrect unfortunately. When you start pushing over 70, VCM becomes less reliable and drops out for longer periods as your speed increases. IMA does provide torque to maintain VCM but what you take away you have to put back and IMA gives away what it can very very quickly At 80 +, you will be lucky to see VCM on a downhill only. Once on all 6, the AH consumes as much fuel as the std. V6. Possibly even more given the extra weight.
