    Considering buying a new car. Husband has a Fiesta that comes with a IL Eco boost engine with 125PS and claims to have more power than the older 1.6L. It has good acceleration
    I have a 1.3L Yaris which is fine and I like to have a reasonable amount of power . The Aygo is only 1L but is big enough internally for me and looks good I think. The website doesn't tell me the PS value but I'm wondering if it's just Ford who have these low capacity / high PS engines or would the 1L Aygo have the additional power as promised by the Ford. I want a car with good acceleration. I don't want a Fiesta.
    Only simple answers please - i don't know much a bout this.

    I assume you have rung the dealer up and asked.but basically while a 1 l might have good acceleration its the tuning which makes it move smartly.Depending upon how you use it it may be ok for local runs and occasional longer runs or loads,,,but bigger engines,while possibly being less efficient, means you have a bit more in reserve and the engine isnt stressed as much to reach and maintain the speeds and travelling a smaller engine might do,
    the choice of what car is purely a personal thing,,,,but i always take manufacturers comments with a pinch of salt and take the cars for test drive and match them in similar ways..I for example was going to buy Hyundai...but disliked the car when driving in it...in the end i went for Skoda,which while not glamorous was a lot more comfortable,spacious and didnt have the rear view blocked as much by the rear pillars.

    The Ford Ecoboost is a 3 cylinder engine which is turbocharged to produce the impressive power. The Aygo, as far as I can see, is not turbocharged and produces much less power. The Ford therefore will feel much more responsive.

    The other point about some small cars is what you are going to use them for. If you are going to do any travelling out of town at motorway speeds then a small car that sells itself as a city car will BREAK.

    Car buying is a whole lot more complicated.

    Oh dear ....

    The 1litre Aygo manual has a PS rating of 69.34

    I'd go for one in my favourite colour.

    Just had a look at the Autocar website for both models. The Aygo seems to share the same platform as the Peugeot which is the car I had in mind when I talked about cars breaking. It's not about power output it's about the way the engine and running gear are built and some cars are simply not up to the task of high speed motoring out of town. This is not made explicit in the sales blurb.

    The Ford engine is in a different league to the Toyota. Although they are both 3 cylinder 1.0L engines, there the similarity ends. The Ford needs to be compared with a typical 1.6L petrol engine in terms of power and torque.

    Although I own a Ford, I wouldn't buy one new. The way that Ford sells its models with different levels of trim makes it poor value against lots of other manufacturers. For example, many Ford base models do not come with any kind of air-con whereas other manufacturer's equivalent models do. Residuals are pretty dire too when it comes to trade-in or selling on. Great for a secondhand buyer but not so good for the new buyer.

    Why has PS rating become a part of the English discussion about cars?

    Simple answer? I don't even understand the question!

    Good question.

    PS is German for HP. They've got a sauce, ain't they? Didn't anyone tell them they lost the war?

    PS=Pferdestärke =horsepower

    Depends on the car of course as you say. I had a 1.3 Ford KA for years (until I wrote it off) and did 500 miles a week during term time, which was about 60% on motorways and it was fine.

    What is a PS rating anyhow?
  13. harsh-but-fair

    harsh-but-fair Star commenter

    PS stands for Pferde Starke which is a german measurement roughly equivalent to our old Horse Power.

    This is a recent development related to describing cars as "city cars" not simply small cars. One way of reducing fuel consumption is to make the car as lightweight as possible by reducing the weight (and strength) of engine and running gear components. Cars trundling about the city suffer less stress on these components than cars travelling along roads at high speed. This is fine if you only trundle around cities and don't disappear down any inconvenient potholes.

    1PS=0.986 horsepower
    It is a metrified version but not quite equivalent.

    Unless you're a petrolhead, these things are not really as important as the manufacturers and car magazines make out. I accept that if you make lots of long journeys you'd be better off with a large car, but if you are largely talking small cars and city driving, any of them will be adequate in terms of performance. MPG is the more relevant factor. At least as far as I'd be bothered. That and relative comfort. Opt for whichever one you feel happier driving.

    You have to remember that the small car market is the most competitive, so anything that looks like an advantage for the salesman gets prominence in the sales pitch. Confuse people with new names for power so they don't know what the deal is. Add another cheap gimmick that rarely gets used but makes the specification look more impressive.

    Simple question to ask, is do I honestly need it? Work out you don't, work out they'll all do the same thing as far as getting you to work and then you can put yourself in a better position to haggle the price down. If you set your heart on a particular model, the salesman has the upper hand. If you can walk away to a better deal, the price will drop.

    The original Mini back in 1959 when it came out as a new car had 10" wheels and a 848cc engine producing 34hp.

    Now if you wanted to use the car to drive every now and again from John 'o Groats to Land's End, it would do it. You might take a week to recover from the experience but there was nothing inherent in the design of the car that meant that this sort of treatment was precluded.

    With some types of "city car" that capability has been effectively designed out. If you use some types of city car for regular out of town driving it will break because it has not been designed to do that sort of thing.

    I say "some types" because not all manufacturers have gone to these extremes. But the fact that some models of cars lack a true out of town capability is not really well advertised. These are specialist cars built for a very specific environment and the fact that they will do 70mph along a motorway does not mean they were designed to withstand such treatment on a regular basis.

    Do you have any evidence to support this assertion?

    Exactly what breaks?

    Anecdotal. This is very recent. I had a relative bought a city car and went tramping round the country (half terms and holidays). It broke down several times. Every time they were asked what they did with it by the dealers who then said:"Don't you know you can't do that with a city car?" As if everyone is expected to know this. Another aspect of this was the Fiat that featured in BBC's Watchdog that wouldn't go up hills. This was because the engine was tuned for maximum economy to get the car into the lowest tax bracket.

    Car manufacturers have had to do a great deal of work to achieve targets set by governments all round the world to conform with Kyoto. Some products such as the Ford Eco-boost is one way but a tried and tested way is to skim material off here and there to reduce weight. There is a limit, however, to what you can do with bodywork because that affects the NCAP rating.

    The other things you can do is skim weight off the engine and running gear. So you replace cast housings with pressed metal. Thinner, lighter but much weaker. OK if you only do lots of short journeys but not really up to the job of a good regular blast up the motorway.

    Another way is to do away with the spare wheel. Not even a spacesaver. Some models of cars have no provision for any sort of spare wheel. It is simply not an option.

    The point is that just as, in the past, it was never necessary to ask whether a car had a spare wheel (it had), it was also never necessary to ask: "can this car only be used in the city?"

    Ironically some cars must be given a good blast every now again to clear the DPF. If not a light comes on on the instrument panel and you are faced with a very large bill to replace the DPF. How many people know to ask about this?

    Like I said, new car buying has gotten more complicated.

    Not if it runs on petrol.
