The short answer to your question carl is - a manual rather than auto.
Cem - F1 cars have huge bwings at the back to push the car onto the road on very high speed corners where the mechanical grip would be exceeded. at speeds up to 60mph aerodynamics will have little influence on anything.
Your example of a wheel with or without a tyre, demonstrates mechanical grip to me, which does require some weight pushing down upon it to provide traction. Quite different to aero downforce, in the real world of driving on the road.

[cem_devecioglu]

Downforce will not have any influence at all accellerating from 0-60mph. ..............asuming you are talking about aerodynamic downforce ?

if there is no downforce, there will be no grip  and no acceleration

why do you think f1 cars have those wings ..

So now I need a spoiler just to get the bugger to move? 

not simple to answer.. depends on your car weight, tire profile , engine torque.. :-/

Sounds like it will be more effective if I just get someone to push me everywhere...

The reason I'm a little anal with 0-60 times is if I don't mind having a car 1 second slower than the calibra, then I won't mind having a v6 1 second slower than the faster 2.5....so by this time I have lost 2seconds slower than the car I started with, then I just as well get a diesel....

1 sec is a serious time at 0-60.. generally the differences will be within 0.1-0.2 secs at maximum for the 2.5 (of course not talking about auto-manual difference)

In that case buy a 3.2 and be done with it. 

It's only petrol after all.

Failing that buy a 2.2 dti and replace the engine with a late 3.0 v6 diseasal lump from a Vectra c.
184bhp and 380lbft iirc.

i wouldnt even like to guess how much it would cost for me to run the 3.2, let alone buy the car to start with....

We have had the discussion about decently serviced cars being quicker than poorly serviced cars, but the same applies to economy.  A very well looked after 3.0/3.2 will be more economical than a poorly looked after 2.5/2.6.

From that point, the likelyhood (not a rule, but likelyhood) is a 3.2 (newer) will have less mileage, less wear-and-tear and..... you know the rest.

When buying an Omega, go for the best spec'd car you can find.  When buying the V6, economy is completely irrelivant.

As a side note, you sound like the kind of chap who enjoys sticking their foot down from time to time..... any of the V6 engines on full chatter will drink more than George Best on a Stag Do.

Just my two-penneth worth. 

[05omegav6]

Well said BM. I wouldn't run one as a cab unless it paid.

If you want economy, buy a pug 107, if you want performance buy a porsche, if you want a quick, comfy cruiser then buy an Omega.

Rocket science it ain't.

hi mr C. i still dont understand your fascination with 0-60 lol i recently tried to do it on real world roads and only by going out very late at night would i have had a chance to actually do it cos of the amount of traffic.

as said if you want a very cheaply priced luxury barge go for an omega. an eco car go for pug 107 and a fast car go for.....well something else 

[Banjax]

i'd love to see a Calibra do 0-60 in 8secs in a straight line.


not the time i doubt, its the straight line bit i dont believe 

[Mysteryman]

This is becoming another bus thread. Is it a wind-up? 0-60 in an omega? One word....slow.

There not to hot around the corners either

Are they really that bad?

[cem_devecioglu]

The short answer to your question carl is - a manual rather than auto.
Cem - F1 cars have huge bwings at the back to push the car onto the road on very high speed corners where the mechanical grip would be exceeded.

grip for f1 cars from their original weight is very small compared to the downforce from those wings as they are like mosquitos for that reason they use very wide tires at the back where wind downforce is small at starting speeds..

at speeds up to 60mph aerodynamics will have little influence on anything.

on those tracks even 0.001 sec is critical so they try using every factor to the limit..

Your example of a wheel with or without a tyre, demonstrates mechanical grip to me, which does require some weight pushing down upon it to provide traction. Quite different to aero downforce,

not different.. it produces grip (like normal mass) as a result 


in the real world of driving on the road.

Banjax, turbo models with 4x4 can easly go below 6 secs.. I know a mechanic , who owns one and pushing around 380-400 hp..

as stock ..

but if some money spent in a professional garage, you will change your mind.. STMO , will you send me some money

[Kevin Wood]

I don't know where this idea that cars get slower with age came from.

Give me a choice of a tight new engine and a nicely loosened-up old one in a drag race and I know what I'd choose.

Yes, if it's in dire mechanical condition, power output will start to suffer but, in my experience, and engine will perform well, once run in, until it's knackered as long as it gets basic servicing.

.. and if anyone still doesn't believe weight is an issue they need to try a Westfield. Yes, even 2/3rd engines aren't as tedious and dull when you give them a tonne less weight to carry. (17 year old 4 pots at that  )
