Very timely question for me this...
My works Panda 4x4 1.2 petrol returns c.38mpg when it's just me running round the dales, and c.29mpg when pulling the trailer round the same area.
We've just been given a Panda Cross for a weeks trial, and I've just had a quick hours trial myself to see how it compares. The trip comp is showing a trip of 700 miles at an average of 38mpg, and ave speed of 35mph. There must be some seriously heavily footed people round here as I don't hang about at all - or is the car just not then economical compared to the petrol car?
Having read the previous comments, I think I'm going to have to conclude that they must breed 'em with heavy feet in Yorkshire!
But, the engine pulls so well at lower revs with so much better torque than the petrol, which would make life when pulling the trailer so much easier so for reason, that's the version I'd have if I was to change from my petrol Panda. Plus it goes really well too, really fun! Rear suspension is still a bit stiff and is quite noisy so I suspect the car has seen some action over its 7000 miles of life so far!
