    Focus st query

    Focus st query 13th Jun 17 at 4:58 PM
    Hi all

    Looking at buying a 2013 focus st but a colleague posed an interesting query. My daily commute is about 3 miles max along 40 limit roads. Based on this i will never get car up operating temperature days i use

    Based on this would that make the st a bad choice and in fact rule out cars of this ilk?

    Interested in any feedback and always thanks

    Drip feed information, and assumptions will be made. It's not just this forum, it's the way the world works.

    Fair point. I Leave my house at 7.45 after getting the kid's ready to school and starry work at 8. My car is also the family vehicle at weekends so any trips or busting the in-laws who live forty minutes away is in my car, and we visit them once or twice a month.

    Just avoid getting a STD (or whatever the diesel version of the ST is called).

    I did 1.2 miles 4 times a day in a Saab turbo for 7 years, never caused any problems. Did tend to use it properly at weekends though.

    Turbos spin (very, VERY fast) the entire time the engine's running.

    Turbos turn at anything up to 120K RPM (exc. really high end stuff) and reach that from idle RPM in 1-2 seconds. Even at idle, the turbo cartridge is turning at thousands of RPM.

    So operating temperature is a red-herring then? Or is the point that you shouldn't floor it until the engine is warm? The question is then will the OP ever need/use any boost... which is what I was saying about my previous commute. I got more use out of the stop-start system!
    One day I'll think of something witty - Apparently I have!

    No, operating temperature is far from a red herring. It's very, very important. Just spinning is not the same as spinning under load.

    Ye-e-es I got that bit. So on a slow commute in stop-start traffic, is the turbine under any significant load or not? If it isn't - then the OP has less to worry about temperature. If it is, then surely there would be huge warnings in the manual about not driving off until the temperature reaches a certain level. There aren't any in mine...

    I do see the other end of it from time to time - stopping after a long run/hot day and the cooling system keeps going even after hitting the Engine Stop - which I've always assumed is to protect the turbo or related components.

    For a 3 mile commute I wouldn't want anything other than a tiny-engined petrol car. Anything else will give dire fuel consumption and be quickly ruined by those kinds of runs.
    That tiny engined petrol car will have similar problems to any other petrol car.

    An electric car would be the logical alternative - no warm up issues with engine or cat, nor wear/charging issues on the (12v) battery.

    Renault Zoe, Nissan Leaf, BMW i3, Kia Soul EV, Hyundai Ioniq.

    You could even go hybrid and never use the petrol motor for your commute - Mitsubishi Outlander etc.
    I have 2 children so after work i need to pick them up from the childminder. This is not possible on a bike.
    You missed that from your first post if you don't want bike suggestions!

    Driving three urban miles each way, twice a day, five days a week, is a very quick way to kill any car.
    Not an electric one.

    There some people here who are so rude making a judgement on a person they have never met. I am surprised anyone ever asks for advise.

    I have 2 children so after work i need to pick them up from the childminder. This is not possible on a bike.

    Thanks for the informed opinions about the question i asked

    Depends entirely on their driving. If they accelerate hard out of every junction, scream up to the back of stationary traffic, and hammer the anchors on, then... yes. If they just gently tickle along, then no.

    A Diesel has no throttle, so the air throughput depends only on the rpm. A petrol has a throttle, to keep the mixture constant, so the air throughput depends on how hard the engine is working. That in turn means at low effort, the turbo won't be spinning fast, and its oil needs are lower.

    So if you are gently driving your kids to and from school, it won't matter so much that its cold. The problem also isn't the poor fuel economy, its the tax, insurance, maintenance and depreciation, being divided over so few miles, that the cost / mile is worse than a stretch limo. However, if you enjoy being in it, and gets some miles in otherwise, then why not ? I once had a big car and a small car ; but denying myself the big one for a journey, wasn't worth the financial saving.

    Thanks for all the input. Electric car not a option as i don't habe a charging point and my house is a good 100 yards fron where i park.

    Still tempted with the st as i can drive sensibly when needed. However the inputs around damage with the low miles and not bringing the temperature up has tempered that.

    For the people saying i don't need a car that could be applied to most people who live and work local. I have decided the laziness of a car suits me and the call now is which one

    A petrol car is a petrol car, whether it's a tiny little 1000cc or Focus ST. A diesel would be your worst choice.

    In 2001 I lived 3.8 miles from work, I commuted in a Westfield kitcar 2 days a week and I cycled the rest, I then cycled all through winter, unless it was snowing and then I walked (1 hour walk).
    The car did get a good long run every weekend though......

    I now work 20 miles away, I drive every day and i'm feeling horribly unfit
    Having the last word isn't the same as being right.......
