Looks like a new Mondeo will be my next company car, when my B5.5 PD130 Passat retires with full honours and just one black mark -- the front suspension knuckle joint :-/
I'm going for the estate 'cos it looks nice. In the A*t*c*r road test of the estate, they comment on something called "feed forward" torque:
"The 2.0-litre diesel has a re-mapped fuel system that helps pulling away from the line smoothly. Called ?feed forward?, it provides a pre-emptive boost of torque to the engine before setting off, and seems to work well."
This is the only time I've seen this mentioned, is it just on the estate or is it on all models?

Sounds like marketing hype to me.

Its just a fancy name for tweaking the engine cpu to deliver more turbo boost at lower revs at pullaway than it would normally. And it will apply to saloon and estate.

I saw reference to this on the Fifth Gear test of the car a couple of months ago - and a very good test it was as well, but since no-one else will admit to watching it....
|
|
has 5th gear improved?.........if it has i'll consider watching it again
|
Well I enjoy watching from the closet - its more about cars and the odd bike than about than the presenters.....
I have to say I've seen a couple of these new Mondeos in the metal, they look huge with almost 5 series proportions. The 5th Gear test was pretty convincing in my opinion. The cars are full of charming little thoughtful things......still fwd though.

The 4dr Mondeo is bigger than 5 Series, and all models are 40mm wider.
|
|
That is shocking, the 3 series makes even more sense now against a Mondeo !
|
Choosing a new company car, the Mondeo was an option. I like the look of it but more expensive per month. But in the end I thought about the size and I believe with mirrors it is 120mm wider than the current car. I use car parks in Manchester where that would be a real problem - already got dents in the doors of the current Mondeo because doors opened into it. So went for something about the size of the current Mondeo.
There was/is a bit of me saying but you should get the latest model and not one from 5-6 years ago (Mazda6/Avensis) for many reasons. But decided not to go down this route. But the new Mondeo is sure to be quite a safe car.
As for "feed forward torque" is that linked to transient overboost ;-) Another marketing term.

Yes, and probably to flux capacitors as well (link to thread about De Loreans).
I've seen some new shape Mondeos but not driven one yet, it's a nice looking car alright. The last model never really troubled the best seller lists here in Germany so it'll be interesting to see how the new one does. I'm still amazed at the size of it though. Here's a comparison between the Mondeo 2.0 TDCI and the Mercedes E220CDI:
Mercedes: Length: 485cm Width: 182cm Height: 148cm Unladen Weight: 1615kg
Ford: Length: 484cm Width: 189cm Height: 150cm Unladen Weight: 1557kg
That is one big car.

Nice but Audi-ish front, back end is a late 90's Laguna though. What happened to the brave Ford that gave us the astonishing leap forward of the Sierra, the sharpness of the Focus, the nuttiness of the Ka (and let's face it, the ohmy...they haven't have they awfulness of the last Granada)?

Bagpuss I think you might be comparing the Mondeo 5-door with a E-Class saloon. The estate Mondeo is longer and the saloon longer again. I am pretty sure a saloon Mondeo will now be longer than an E-Class!
Be okay if the "Focus" filled the gap but it's a lot smaller and will never compete with C-Class/3-series. Okay that's Ford vs. MB but even the Volvo S40/V50 a lot smaller and the old X-Type is the old Mondeo.

In the traditional sense (as opposed to the marketing sense), feedforward means that the controller acts directly on either a demand signal, or a disturbance signal. Feedforward can be used as part of a system containing feedback.
The use of feedback control on its own is much more common - a signal from the output of the system is compared with the demand, and this forms the input to the controller.
The advantage of feedforward is that you don't need to wait for the system to respond to either the demand or the disturbance - you get your control action in very quickly. Feedforward relies on your mathematical model of the system you are controlling being close enough to matching reality. i.e., the system might act up on an older, worn car, where the engine doesn't react as the feedforward controller "thinks" it will.
In the context of this application, perhaps the action of the clutch is monitored (a speed sensor on the gearbox input shaft?), and the action of bringing the clutch up is interpreted as a demand (or a disturbance depending upon how you look at it!), and the appropriate action fed-forward.
If left to the idle speed controller, the engine would have to slow a little as the clutch is brought up for there to be any corrective control action - which itself would not produce an instantaneous increase in torque, which itslef would not produce an instantaneous increase in engine speed.

In laymans term it's like turning the temp up on the oven before you open the door to check the souffle - because you know that opening the door will drop the temp and destroy it.

>>turning up the temp>
Nice analogy!

It's probably all done digitally, Cheddar :-)
Apologies for a feeble Monday morning pun.....

Probably done to make the thing a bit harder to stall.
