2.0's are underpowered, 2.5 is the best bet  :y

I have had both, the 2.0 is sluggish but is better on fuel. The 2.5 is am absolute joy to drivein comparrison but is worse on fuel. All depends really what you want.

I have enjoyed 2.0, 2.5, & 3.0's, and if you can afford to run one and find a well serviced example I would always opt for a 3 litre :y.  

However, if financies are restricted :'( go for a 2.5 CDX; they are superb and almost as good as a 3.0 Elite to drive.  You really don't notice the difference between the 2.5 and 3.0 for normal driving.  It is the top end boost that is missing with the 2.5, especially if like me you love (safe) speed with bhp to spare.

The weight to power ratio of the 2.0 does mean it is underpowered.

as project cars i have owned both 2.5 & 3.0 V6's

I still have a 2.2, BUT thats cause its a manual.

Driven 2.5 facelift manual, did not feel much difference in power compared to my 2.2.

2.0/2.2 are a lot easier to work on as well.

If you go for a V6 i would go for the 3.0

2.0 isn't at all bad but the V6s are better

I had a 2.0 for seven years and it was ultra reliable. Had a V6 for about 4 months. fast and smooth but then broke down. If reliability is more important than speed/power, then go for a 2.0, with service history of course. Got a 2.2 now and I love it.

This great info guys/gals. ANybody got a 2lt/2.5lt in/around Southampton and wanna take me for a spin?

Problem is once you driven a LC all power (well most of it) seems tame  :-/ My 2.6 Dip is 150 ponies (when new) and is ok I understand the 2lt's are 136 but I think the Omegas are heavyer. Still all good info thanks guys

You've driven a Lotus Carlton & you own a 6 pot Carlton and you're now asking whether you should buy a 4 pot Omega or a 6 pot? I'd have thought that you've already answered your own question!!
Big is best .....  bigger is better still!! You want to buy a 3.0 or 3.2 Omega. You know it makes sense!! The fuel economy between the V6's isn't that great, but the 2.5 doesn't go like a 3.0 does .... assuming they come with proper 2 pedal trasmission.  ;)

Number of pots isn't really an issue What I am trying to do is give myself more options. At the end of the day once my wobbly ankle is better I can get my power fix by taking the LC out. I really don't know nowt about omegas. So just trying to arm myself with info. As for fuel consumption.... Well Else only does 17 if your being nice start abusing it and it's single figures  :o :o :o

Oooops! Just testing! ::) I meant Diplomat!  ;D  :y  :y
A change? An Omega is newer but not neccessarily better. More toys in the Elites than you might have had in the Carltons, A/C that works, cruise that's more likely to work.

OK. ::) A/C that's more likely to work, and it's already running on R134a so you don't need to convert from R12 or get the bull$hit off all the A/C experts who want to 'drop in' Rsomething else into your system.

I ran a 2.0 auto for nearly 4 years, it was a good car, but was a bit sluggish, but then it wasn't bad.

I have driven a few cars so

Carlton 1.8i auto (DEF)
Carlton 2.0 auto (high compression) (DEF)
Omega 2.0 auto (prefacelifts)
Senator 2.5 auto (F)

1.8i slowest by a long way
Omega a little slower off the line but at road speeds is quicker.

The 2.5 auto Senator - slower than the Carlton 2.0s!! The boat anchor engine is too heavy and not revvy.

My current 2.6V6 is similar in performance to the 12v 3l straight sixes.

GUAG list of big Vauxhall autos I have driven
[C]arlton enator,
  • mega

1.8 C
1.8i C

2.5 S (a slug which should never have lefted Russelheim)
2.0 O
2.0 C

2.6 O           \ Pretty similar, torque & heavy engine vs lighter engine, and a bit revvier
3.0 (12) S    /

3.0 O

Not driven 2.6 or 3.0 24V, nor 3.2V6

So my advice is buy by condition, I'd guess that the 2.2 and 2.5 would drop between the 2.0 Carlton and the next pair - 2.6V6 seems noticably torquier than 2.5V6

I'd say 2.5 - the 2.0 is a little too underpowered to the point of economy suffers as you're always driving harder.
