I used to run a Saab 9-3 2.0t 4 speed auto with 150bhp which used to return a calculated 23 - 24mpg on my 15-20 mile commute to work. The Civic i-shift with 140bhp is returning 35-36mpg using the same routes - and is much more  ! |
Yes the performance is a worthwhile gain aginst any supposed loss of economy. I will check the mileometer carefully. I must admit making the presumption that it would read with the same degree of accuracy as the speedo, being driven/generated from the same source.
