Performance
« on: 14 October 2007, 05:34:23 »

Hi all.
Not really sure if this is in the right forum so will apologise now if it is'nt. I am growing increasingly disillusioned by the performance of my Omega. its a 1996 3.0 auto Elite saloon.
It has been serviced regular, runs on branded fuel (Total mostly) but I am finding more often than not that 1.9 diesel Passats are more than a match when pulling off & more responsive overall. I know they now have 6 speed manual boxes which means shorter gearing but uses power much better when required.
I would have thought 208bhp was quite impressive when compared to 170 but i see on here the miggy produces 199 lbs of torque compared to the VW's 258. Is this most likely due to the fact it has a turbo or does the autobox hinder performance as greatly as I think, kick down seems more like a volume control rather than an acceleration tool.  May just be my driving style as I am not the Stig.  ;D
Just raised this as a debate to see if others suffer the same. Also are manuals more responsive to throttle changes?
Thanks in advance
Jez

I'm sure Paul M will be along soon to tell you how much he ikes proper/auto  ;) boxes.  ;D  ;D
When you're comparing the various numbers between the Omega & Passat are you also factoring in the weight of each of the cars? An Omega Elite weighs around 1700 kg and so you're not going to keep up in the Traffic Light Grand Prix. If you want a sports car sell your Omega.  ::)  ::)  :y

Use sport mode, even a 2.6 will have most other cars with sports mode

omega is heavy, got  long gear ratios and the engine is factory tuned as least common denominator what it can handle..
racing from the traffic lights ,  not good idea..  unless engine modded..

if you are insistent on start up racing try second hand impreza sti .Will be cheaper then modding omega

Will move to general chat to get a wider response....

However....  As long as timing, fuel, filters, plugs, sparks etc are spot on then the cars are quite sprightly for their 1.7 tonnes weight but cannot compete with some other cars which are lighter, better geared and with greater torque.  

Short shifting torquey diesels can and do outstrip potentially 'faster' cars, in both manual and auto versions.

Also with a car the weight of the Omega, its the Torque which will play a major roll in regards to acceleration.  It's not just about BHP...

It's not all about torque either, because the torque at the wheels depends on the gearing. Whilst a TD might generate a higher peak torque it's all over at 4500 RPM whereas the V6 generates pretty much flat torque from 2500 RPM to over 6500. This maybe doesn't make it feel as fast, but to generate the same torque at the wheels over the same range of speeds a diesel car needs to be thrashed relentlessly through several gearchanges whereas an Omega will do it pulling through just a single gear.

So, you might lose the traffic light GP but I always console myself that I've done so effortlessly and with just a light growl from the V6 whereas TD engines are most unpleasant when thrashed.   :) That's what an Omega is all about IMHO. I'd have bought a Type-R if I was interested in winning TLGPs at the expense of comfort!

I think you are all right. Think I may be getting twicthy for a change. Have had this longer than most other cars so suppose i must be content in some ways. Maybe i should consider a manual model when i next change cars. Just found that Passat weighs 1520-1648kgs dependant on model so not greatly lighter. Anyway I knew subject would provole responses so thank you for them

I would add that my MV6 3.0l auto is 0-60 sub 8s. 3 k oil changes, and later autobox software help...

Thanks for more recent additions. The software upgrade sonds a more realistic & cheap route.
Where would I be able to get the version installed checked. I normally use a Vaushall independant based in Nuneaton. They have Tech1 there.

my 3.0 auto is quite quick for the size of the car, i think.

when you switch off traction control and hit the sports mode then try pulling away, mine takes off like a rocket, ok, its not a 0-60 in 3.5 seconds or anything but hey its an omega!!!

it always puts a smile on my face.

and i always tell people... you may be quicker off the lights but keep an eye on your rear view mirror and get ready to move over 8-)

 :o

How on earth are VW (and everyone else) making their cars so lardy these days?
I wouldn't have believed a Passat weighs as much as a V6 Omega but it's near as makes no difference the same (my MV6 is listed as 1650).

1) It's front wheel drive so no propshaft, diff, simpler rear suspension, smaller gearbox, shorter bonnet
2) It's not quite as big
3) Omega has a V6 with a cast iron block up front. Not sure what the Passat has but the only way the Omega's engine could be heavier is with cast iron heads!
4) Presumably we're talking about a manual box (6 speed, admittedly) instead of an auto.

Gone are the days of the nice, chuckable MK2 golf (and the older passats weren't too bad on that score). You seem to need to buy a Lupo to get a light car these days, and then you get painted metal interior and just look at the engine options. :o

No wonder the old school VW's fly when they get a modern engine transplant!
