If you change gear before 3k all the time then two things:I change gear before 3k because i dont drive like a t
t.1) you are using maybe 80 of the available 220 horses and
2) your engine is possibly coked up to the eyeballs and now runs like a pig.
May I humbly suggest you sell the 220st and get a 1.2 fiesta. I'm fairly sure you will be happier.
A mate of mine drives like the gentleman above. Apparently revving "above 3000 rpm is for boy racers". He just will not believe it is bad for the engine.
So far he has killed:
Astra Mk 2 1.3
Megane Mk 1 1.4
Sunny Coupe 1.6
Sunny hatch 1.6
Primera 2.0
306 D Turbo
with his daft attitude. Trouble is he's taught his wife to drive like this now too, so she's doubling the problem.

Am I correct in thinking the SDI engines, while being slow, are extremely reliable?
There are several Octavia SDIs used as taxis up my neck of the woods with well over 300k on them.
Anyway, this new, or expensive enough?!

What an utterley hatefull thing,I am dismayed and depressed by the existence of that car at that price,I know some people dont care and just want economy/reliability but thats just an automotive white flag.There are several Octavia SDIs used as taxis up my neck of the woods with well over 300k on them.

sixteen point seven seconds.
That's plain ridiculous.
If you look at how diesels work best, and how we try to run them at sea we use them at 90%MCR (maximum continuous rating) which for a car diesel engine would equate to around 3900rpm.
The advantage is that they run at constant speed for days on end and this 90% MCR speed allows maximum EFFICIENCY. The maximum amount of power is extracted form each joule of energy produced and some of the latest generation low speed units are 50%+ thermally efficient.
However, for a car where the revs are very variable unless used for long distance (Lorries or long haul car drives) they are never that efficient, but still more ECONOMICAL than a petrol.
Please note the difference between economy and efficiency.
The chap earlier who runs his 3.0 petrol at <3Krpm is getting neither.

It's not so much hating it as pure bewilderment as just how much crazy you must have to buy a large, fast, expensive to run car. Then complain about how much petrol it uses while not using any of the power when that engine is tuned for maximum efficiency high in the rev range (which is different to economy).
