Early days using the C.O.D. But very impressed so far. Is very quick (by my standard of cars so far) and very quiet, I hope gets a bit noisier when you floor it but haven't done that yet.
MPG seams to vary a lot depending on journey, in stop start traffic can get down to 17 mpg And on open road up to 60 mpg so far when I picked up from show room did 35 miles and got 35 mpg, yesterday did about 30 miles in dynamic and got 45 mpg, today did 30 miles again in eco and got 42 mpg, so is a good start and shows drive select is not the answer to mpg, more to do with how you drive.
The only thing I noticed so far is because it is so quite, I was tending to push the accelerator I little harder than necessary, when just following in traffic, which lowers the mpg a lot without accelerating much faster. No point if you stuck in traffic, it makes about 10 mpg difference if you get it right, it is quite happy accelerating at lower rev's than you expect. That said when you do get a bit of open road, you don't have to floor it to get to 60+ really quickly.
the engine seams to be very sensitive / responsive which is good fun, but the mpg is going to vary far more than any of my previous cars depending on drive / driving style, massively enjoyable though, and the weight reduction over the 2.0 ltr. Diesel I test drove sharpens up steering and add an element for fun / sportiness to the handling and cornering as it seam to slightly improve the balance of the car.
but I think the diesel will delivery a far more consistent MPG as is less dependant to driving style and I liked the noise it makes.
