With only 75Bhp and 0-60 in over 15 seconds it's not going to feel quick.

well that depends who you talk to. The reality is that the manufacturing process and tolerences of such have improved to a point where the act of 'running an engine in' is now gone. Aside from the fact that cars are not designed to live long enough to reap the benefits of this good care.. !

So in short - no.

So secondly, what car is it, what was your previous car ( just being nosey ) and what makes you think that it has no ' pull ' or acceleration *torque*

You don't need to, no. It will feel different after a week or so of driving though. I was quite disappointed with my new car because it was just so soft and felt like it was slow to accelerate compared to my little Ka. It's so much better now and i've had it about 3 weeks.

I got a 12 plate Punto btw. What's yours?
I agree with the above that modern engines don't really need running in, although it's not a bad idea to take it fairly easy for the first few hundred miles.

Id disagree that modern engines aren't designed to last as long as old engines, they are designed to last a lot longer and the life expectancy (without major work) is far higher on a modern engine than it ever used to be.

Also keep in mind most modern petrol engine (especially the smaller ones) tend to produce the power far higher in the rev range than older engines, a lot of people don't realise this and basically under drive them.

cheers for the info on sure it will be fine
What you are experiencing is a car with tall gearing. You need to work the car a bit harder in the gears, i.e. don't change up so early in the rev range, keep the revs above, say, 2,500 rpm. You will find your car much more responsive. Most cars are quite high geared now primarily to give them low exhaust emissions and good fuel economy, but this does dull the potential liveliness of the car.
Chuckfickens - are you stalking me lol !

Ok, let me reword my response slightly. The expectations of the modern engine have differed over the years. Manufacturers now build an engine that is designed to pack a higher mileage into that short life span.
I've worked on vehicles for many years and have noted the differences - some great, some not so great. We are clearly working toward ( imho ) another GM where manufacturers are increasingly and more predominately using parts from different manufacturers. I know that this has always happened, but it is more so now. Buy a Vauxhall = Fiat engine ... Buy a Focus = Renault (gulp ) engine .. Buy a Nissan Micra = Renault Clio you get the picture. Failure of the High Pressure diesel pump will now almost write off a car at a main dealer when you consider that some(main dealer price) will quote in excess of £1500 pounds or even suggest new engines quoting that the pump has started to break up internally etc,...

Slightly off topic but you hopefully see my point ... now back to those strange circles ! lol
I think what Harley was getting at is that even driven hard, the rest of the car will fall apart long before the engine gives up. Especially the suspension, given the state of the roads.
