So Mr Driving god. How do *YOU* handle being below the boost threshold for the gear you are in?

Because there is *no* go without boost and if your revs drop too low you're out of it.

Hell, stick a manual diesel in 1st, get it moving and then plant your foot. Count how many seconds until it finally lumbers up to the boost threshold and starts to move. 7-10s or so. Every single petrol from a lowly 1l will have instantly accelerated.
Heres an even simpler solution for you.

Stand at a roundabout of a junction and watch cars traverse the junction. Bearing in mind an easy 60% will be diesel, count how many end up doing what happens you - ie, nearly get wrecked or slip the clutch or rev the head off the engine. I would say virtually nil.

IF what happens to you happens EVERYONE ELSE in a diesel, then you'd see / hear it happen all the time. And it doesnt. So its you.

So what you're saying is, all the 0-60 times for diesel cars are wrong by approx 7-10 seconds?

So if i was in a Golf GTD its really going to take me 17 seconds to get to 60 because theres a 7-10 second lapse before it gets any sort of speed up.

Really??????????

Is that how you drive all the time by the way? You "plant your foot"??

You must be a barrel of laughs on the road. There is no need to "plant your foot" to make smooth, "normal" progress in any car.

Are you quoting me without quoting me?

What exactly is your point?

Seriously I'm willing to have a debate on a forum, but not sure if you know where to start or how it works?

What?
A 2ltr 140bhp Golf diesel gets to 62mph in 8 seconds
A 330d gets to 62mph in 5.6 seconds
A 335d gets to 62mph in 4.7seconds

Not sure what you mean by put it in first floor it and count before it moves... It's instant.

Can you confirm the make and model and age of the car you had that experience in.

Yes the 335d is an auto so irrelevent, the rest can be got past by revving it at standstill before you drop the clutch.

It's really not on anything diesel I've ever driven.

2007 BMW 318d E90
2014 Ford Galaxy Titanium TDCI140
2013 VW Golf 1.6 TDI
2014 Nissan Rav4 2.0d

BMW and Nissan were the worst. The BM stalled over speedbumps in 2nd and with the traction control.

But you just told us there was a 7-10 second lag, so are you saying in actual fact in the real world a Golf GTD can only manage 0-60 in 17 seconds if they're driving them in normal traffic?

OR are all diesel drivers revving them and dropping the clutch to get them to go? Thats certainly not what i do and certainly not what i hear out on the road?

I'm genuinely not seeing or hearing this in the everyday world.

According to you, diesel drivers can only make progress by revving them from a standard start and dropping the clutch.

Also, according to you diesel cars cant traverse simple speed bumps without stalling?

And in stop start round town traffic diesel drivers are dropping the clutch and up and down the gears just to make simple progress?

Really?

Do you really think there'd be so many on the roads if they were that-difficult-to-drive?

I have to say that I do find the very short 1st and 2nd gears in most manual diesels really fking irritating for stop start driving, they also mean it takes more effort to get a smooth gear change if you're pulling off briskly. Nobody said they are perfect, that's one of the compromises you make for better economy...

Short 2nd gear? Mines over 60mph.

What is the MPH/1000rpm in 2nd gear of the vehicle you mention.

I think we've already established that whatever diesel car you have can cure the poor, reverse global warming and leap from pacific isle to pacific isle in the eternal fight against injustice so I can't really be bothered "debating" with you. I have the dubious honour of driving plenty of manual 4 pot diesels and very nearly all of them have shorter 1st and 2nd gears than a petrol equivalent to the point where it is irritating. Maybe you have one that doesn't, but many do,

I tend to find when setting off from the traffic lights, in the traffic light race (which is so important)

that I always beat all cars.

This is because I'm on my push bike.

Of course my lag then sets in and they beat me.

(well only till the next lights or build of of traffic)

however I am clearly a cycling god and petrol or diesel, you've all picked the wrong cars.


is this thread even still going ?

who are these people needing to out accelerate every possible vehicle ever made ?

That's just absolute bks.

How can any diesel get from 0-60 in sub 10 seconds if it takes 7-10 seconds in first gear for the rves to rise high enough to hit the boost.

My old Diesel Focus pulls from idle to boost in a very short space of time. In fact plant your foot in first and you run out of revs very quickly.

I'll help you out here because you're clearly not very bright.

1st gear is sufficiently low so that it doesn't need to be on boost to quickly get up to 1500-2000 rpm from idle.

The effect you are talking about is what happens if you leave it in a higher gear and then try to pull away. You need to change to first once your speed gets very low, say 10mph, rather than in a petrol where you can pretty much leave it in second as long as you're not going to come to a standstill.

Generally when people are on dubious grounds they get defensive refuse to provide any supporting evidence apart from personal subjective views.

As you were though.


I would like to know what car it was which had he 1/2gear very short ratios so that we can investigate and state factually here what it can achieve on Rev limit in those gears

Because you can rev it past ~1500rpm and then pull away.

Bingo. He *finally* gets it and admits that you need an extra gearchange. Except that it's not <10mph it's nearer <15-.
