    That is interesting, shows why diesel owners think there cars are as quick as petrols but it`s all an illusion, or is that dillusion

    Waaaaaaay too long winded.

    Look at it this way.

    Power. How quickly you can repeatedly punch a so called expert on the nose.

    Torque. How hard you can repeatedly punch a so called expert on the nose.

    Torque wins.

    I thank you.

    You may well hide matey!

    In many cases diesels are quicker,more easily tuned,and less expensive to tune.With the addition of my tuning box,I now have a car that can easily stay with my mates ST220,and in many cases surprise the hell out of him!

    Unless you're burning up the Motorways (not recommended these days),it's diesel everytime IMO.

    If you read the full piece in the link, it says that basically a dollop of torque (like in a diesel) isn`t much use if you don`t have the revs to go with it, that was my point, and that the initial surge you feel makes a car feel faster than it actually is, I am sure you could keep up with an st220 midrange, but when he gets the revs up you will be running out of puff, and he will just be winding it up, up, and away

    It is an interesting piece though, torque is being talked about much ,more now, even Mr Clarkson is mentioning it now when testing cars !!

    Ah, but lets not forget what kind of engine ran away at Lemans 2006, winning the event on its first attempt

    pmsl, I don`t think we will ever be allowed to forget about the only time a diesel won something


    An engineering milestone though right enough, when a diesel car / bike wins a rally / formula 1 / formula 3000 / moto gp / TT , etc then people will sit up and take notice I reckon ...

    Actually,no,far from it in fact!

    I've driven the ST220,and it was like getting onto a small but quick four cylinder motorcycle after you had just got off a Ducati 998.

    In most cases it is only the regulations that prevent this from happening.If the regulations were simply to go as fast and as far as you can on a set amount of fuel,diesel would win every time.

    I can't imagine the GP motorcycles ever running on diesel, doubt that would work very well with too much wheel spin low down in the rev range
    Doubt that we'll see them in F1 for a very long time either, the diesel engines weigh more than the petrol units and are pretty useless without turbochargers.
    The Audi R10 is really something though, for the kind of race which isn't quite so restricted as the F1: -

    Audi R10 5.5L V12 bi-turbo (with a common rail, just like your veccy)
    650bhp (regulated)
    1100Nm or 811 ft.lbs
