Title: Top speed of a 2.5 V6 auto?
Post by: omegadavid on 12 July 2010, 16:36:21
 Without sounding like a spotty 17 year old.... how fast will a 2.5 V6 automatic go?

Naturally I don't condone speeding on UK roads.... but my 1997 2.5 V6 hit 135mph... and I reckon there might have been a bit more there... only I ran out of road .... I mean 'Autobahn'  :y

When you have the sporty button on and its running well.... what a fantastic car the Omega is

A real bargain for just £500!!!

I think you probably found the point where it starts really running out of steam.  I think top speed is quoted around 140.

The larger engined ones do seem to have more go, and 140 is fairly quick and easy.  3.0l top speed quoted around 150.

My old (chipped) TD never went beyond 125, always due to other circumstances, as still pulling hard. Suspect it would, given time, approach another 10mph. Quoted top speed (unchipped) around 120mph iirc.

Sadly, mine having some poxy speed limiter fitted, I only managed a run of nudging 100 (on suitable race track of course) before I got pee'd off with dipping the throttle at the required points to override it... (85, 90, 95, 97, 100), but had loads more left....

Some-one told me that the 3.0 autos don't change into fourth gear until 110 m.p.h. The same person told me he'd been in one that was driven at 155

Driven hard, a retail spec 3.0l auto will pop into 4th at a shade under 130mph.

These are some of the quoted figures from VX for the facelift models;
2.6 auto saloon, 139 mph. Manual version will do 142 mph
3.2 auto saloon will do 149 mph
And the 2.2 DTI saloon will do 121 mph.

Here's one I haven't tried.

Sport Mode locks out OverDrive yeah?  So, bearing in mind The Omega will hit 130 in 3rd, will it turn Sport Mode off by itself it you try to go beyond 130ish MPH, or will it bounce off the limiter?

Maxed my 2.5 @118mph (Acortding to the cop cars roof box) Wondered why it wasnt going any faster, wonder if it was still in sport mode being the reason.

Some gearbox firmware versions do lock out top in sport.  v9 on a GS820 TCM doesn't. Apparently ::)

I've had another word with my Mate and he says that he was in sports mode when it changed into 4th. at 110... he didn't notice if the light went off!

'99 MY has top speeds for 2.5 auto as follows:

Saloon = 138
Estate  = 132

The Senator's hand book used to say that in Sports mode the car would go into 4th at 127mph. My Omega hand book doesn't have the same info.

Just looked at the 4.2 diff thread that chris started and worked out the speed  per 1000 rpm in all gears, interesting are the numbers if the V6 could hold on till 7000rpm.

            7.80               12.70       18.80       26.00
                              
1000            7.80              12.70       18.80       26.00
2000            15.60       25.40       37.60       52.00
3000            23.40       38.10       56.40       78.00
4000            31.20       50.80       75.20       104.00
5000            39.00       63.50       94.00       130.00
6000            46.80       76.20       112.80      156.00
7000            54.60       88.90       131.60       182.00

Seen 120 in 3rd on my 2.5 auto and it was confirmed by a T5 police roofbox @118mph

But not sure how the gearing differs on 2.5 compaired to a 3.2.

Also cant remember the change point in sport mode, think it's only 5500 on mine.

Never maxed the 3.0 Elite in 3rd. Was scary enough when I was confirmed at doing 118mph on what I thought was a private test track at 3am, never ventured above 100mph since.  ::)

i know of an early ex plod 3.2 estate that easily pulled through 150 with the fuel light on. ran out of fuel about a mile later.  :-[ went like a train 'til it ran out. :o can't quite remember, but is it still illegal to run out of fuel on an autobahn? ::) also not sure if carrying no fuel would have made much difference to the kerb weight of a mig estate?

Most retail spec 3.0 autos change up (at redline) from 3rd to 4th at a shade under 130mph.  On runways, obviously.

Its illegal to run out of fuel on any motorway in most countries.

I've got a limiter on mine when I hit 75 mph it kicks in and an alarm sounds in my ear its called the missus and it sounds like this 'ITS 70 ALONG HERE' ;D
As for the lanes you should see her cr#p herself sometimes think she's going to snap the grab handle off ;D

Karl showed me the video someone had taken showing the speed on the speedo. . . . I must admit I would have soiled myself lmao

Just adding that when i was on the autobahn with Vader, 45mph was reached in first, 85 mph in second, 130 mph in third I then quickly came up to my turn off. On the run back tom tom read 147mph I then bricked it and shut off. . .
Vader was a 3.0 mv6 auto which not many were allowed to drive. I was stupid to get rid of that car. .

Have genuinely seen 151 on the satnav, (158 on speedo) on my 3.0 V6 elite estate, have witnesses (kacking themselves, as was me) and admit to a certain "instability" at that speed, stupid to do it, but really wanted to see what she would do .In retrospect, it would have been easy to twitch the steering and write it off so easily, hard to keep in a straight line, too. NOT something I would want to repeat. Not bad for a ten year old car, but Blimey........instant consumption (if it is to be believed) showed SIX mpg, and I used £20 of fuel in that little blast.

Proud, but stupid.

Reminds me of when I lent my GPS to a mate of mine when we were convoying to Le Mans once.

He proudly showed me the max speed reading where he'd bricked it (about 125 MPH IIRC). ;D

Next week I mentioned "oh, I broke your speed record, by the way" and handed it back reading 174MPH. The look on his face was a picture. :D

I eventually admitted to having set the "record" in a glider. 135 knots air speed with a 20 knot tail wind made it pretty easy. In fact, I could just as easily have gone up to the 146 knot
Vne in that glider and made it 190 MPH. ;D

And after being allowed, some were never allowed to drive it again ;D

That had fantastic suspension on it.  Reckon mine may have had the edge higher up the rev range though.  We'll never know now.

calibrated speedo on ex plod cars useful for such exercises, but frustrating in every day driving. i've a gatso near me that surveys the bottom of a 3/4 mile steepish slope, with a 40 limit. :-/ the number of people who see it and panic brake down to 27mph, believing stupidly that: 1. the limit is 30, and 2. that they are doing 30, is quite frightening  :-/
imo (subject to suitable/legal :-X opportunities) you should have an idea of what your limits are and also the limits of whatever it is that you drive. if you know how your car/bike/truck behaves at its limits, then you'll be more able to handle any unexpected situations as they arise. nothing worse than having to do an emergency lane change at 70ish because a superstar in an audi or sprinter wants to go from lane 3 to the slip road in the last 50 yards and finding that your car pulls right when you stand on the anchors :o
