side by side there isn't a lot in it off the line
but once you are going, there isn't really much to compare, the V6 generates enough torque to stay in 5th while the dohc needs to work the gears to keep up (trust me, been there, done that, 5th gear around roundabouts on slip roads, motorways etc, only had to change gear initially when we set off, then when we got the destination and this was in a bogo standard 2.9 4x4 estate with a slightly breathed upon 2.0 estate behind)

for sure they both used the same amount of juice, but the dohc used more trying to keep up, if the same journey had been done at a less frantic pace i'm sure it would have been much better

and talking of dohc fuel economy, 132 miles, 8.06 litres of fuel
