you can accelerate quicker on motorways without changing gear, which IMO is useful.
It's not torque doing that, it's power. Just the diseasel has more power lower down.
Stick a turbo on a petrol engine and the same thing happens.

0-60, not a lotHow much would you reckon the 30-70mph in gear acceleration time would be reduced by
and what difference in the 0-60 time ? the answers may surprise you.

For everyday driving though, high torque at high revs would be pretty much useless. unless you rag the nutts off your car all the time.

I don't know why people slate us diesel drivers so much. I like the torque but i'm not about to go racing some big petrol turbo'ed car because i'm under no assumptions that i'd stand a chance. I just find the diesel great for motorways due to overtaking power and economy and since i do a lot of town driving as well the torque is great for stop/start traffic compared to a lot of petrol cars i've driven which needed a good dose of pedal to keep from stalling, especially on inclines. If i wanted more performance i'd get another scooby or even buy something like my dads legacy which is one of those imports with the twinscroll turbo etc.. As for the noise, the 320D is quite quiet as was my 525D and the sound insulation inside the cabin is superb to the point i over rev the thing cause i forgot its a derv.

Exactly, diesels are brilliant for these sorts of applications - around town and on the motorway in the way they deliver their power. They are also more economical than their petrol equivalents, particularly in stop start traffic.
This unfortunately seems to be something that a lot of petrol die-hard fanboys deny.
that is what the difference is. the low down torque makes it easier to drive. not need to wait for the revs to build up before it "goes" and the way that torque delivery ramps up makes the car feel nippy. things like gearing and the lack of rev range stop it from being being fast for its equivalent engine size etcthe way they deliver their power.
but you will be able to "press on", accelerating past a car that has just got out of your way, you can do that without having to stir the gearbox[TW]Fox;15191762 said:Just how often do you need to leave somebody for dust in 6th sitting at 80 on the M1?

Reason i ask is that prior to getting my remap, i'd held the oppinion (as others seem to do) that the reason that Diesels accelerate quicker in gear, is due to the increased torque.
Now, the vectra vxr has gone from a dyno proven 300 ish lb/ft to 394 lb/ft
I would have thought a near 100 lb/ft torque increase would provide some sizeable gains in acceleration, rvr if only for in gear acceleration - diesel style.
Now ive been testing with dynolicious that is producing some very accurate 1/4 mile numbers (when looking at what others with similar setups are doing on proper timed drag strips) so i know the data is in the right sort of ballpark.

its the torque at the wheels that is most important as the actual measurement rather than made up flywheel figures , the gear box acts as a torque multiplier. if you had the same gearbox on a diesel and petrol you would really notice the difference
You'd certainly notice how quickly you have keep changing gear and how low it's top speed is..
It's not 'at the wheels' you need to know, power is measured by the dyno at the wheels, it's the thrust vs speed that you really need to know.. that takes gearing/torque into account and shows the only real picture of how a car will accelerate at any given gear/speed..
