I had a 1.4 87ps today for a few hours while the boy was in the garage. Driving around the roads I normally use I didn't really notice that much difference in power. I was expecting quite a big difference but was quite surprised that there wasn't really much in it. I thought it was a bit gruff to be honest and a lot more vocal than my 1.2. It just didn't sit right with me, I much prefer the smoother 1.2 as it seems more rev hungry and is less jerky to drive. I didn't take it on a dual carriageway or motorway so can't comment on how it copes differently (if at all) than the 1.2. All in all it felt a little bit sluggish, probably because I was expecting a huge difference from the 1.2 but didn't get it. I'd expect the 100ps to be a huge difference though!!
