Once rented a Citroen C3 1.2VTi (82PS) in Norway. Had 3 people inc me + luggage in the car. Now in Norway there are long stretches of single carriageway, and every 10 or so km/miles there will be a stretch of I don't know, 1-2 miles where it becomes 2 lanes, and slow lorries etc will pull over, and rest of us overtake, was stuck behind a lorry, doing about 60-70kmh, saw the opening (it was a tad going uphill), floored it in 5th, nothing happened, realising it wasn't a turbo and only had 80odd PS and medium loaded up car, dropped to 4th, revs rose, tried again, good, I'm at least going faster than the lorry, but no, the 2 lanes were closing up ahead, had to drop back. Waited for the next overtake lanes, doozed a little, by the time I realised I could start creeping ever so closer, looked in my mirror, all the other more powerful cars were already in the overtake lane...who were patiently (and in spriting pushing me on to over take the lorry). So I had to wait for the 3rd overtake lanes to finally get past the lorry, resorting to taking the car to the redline to get the job done. So yea, I think anything less than 90PS, non-turbo would be oh so annoying and painful on faster roads...didn't have any such problems with the 1.0EcoTSI
Ibiza SC even with the same 3 (inc me) passengers and luggage on faster roads. Many have asked in disbelief 'it's only a 1 litre?' or 'are you sure it's only a 1 litre?' or 'it's can't be a 1 litre'
