Hi no you can't I did notice from the st forum you had one.It does seem to need a bit more revs to get going from standing start don't know if you find that could be the 19 inch alloys.
I don't find it all that different from my mk 8 ST. One 3 cylinder engine to a slightly smaller one. Could also be linked to the big belt starter/generator. Or even fuelling at low revs.
looks nice in white too. When I saw mine in showroom in grey matter I loved it and still do but when I went to pick it up they had put a white one in its place and I thought wow that looks nice but having the white fiesta previously I did want a change. I also initially was gonna get the ST 3 fiesta in silver fox and was so close to doing a deal on one before i come across the puma and to be honest its much more practical for me so not disappointed . I could have waited for the puma st and had best of both but got a decent deal and my fiesta was due money being spent on service and possible new brake pads so saved few hundred there. If I continue to like the puma though the st will be my next car in maybe 2 and half years. Enjoy
