MORE power what to get: 2.5,2.5si or 3.0si??

Hi,

I was wondering how big is the difference of the acceleration (experienced by driver) between an euro version 2.5 and 2.5si? The euro models both have 2497cm3 but a significant difference in power 177hp vs 218hp and torque 230nm (3500-5000rpm) vs 250nm (2750-4250).

I’m owning a 2.0 at the moment and looking for a nice 6 cylinder to get more power and great sound of an inline 6 engine. Yesterday I test drove a 3.0si coupe and was really impressed about the power. A HUGE difference. A 2.5 (177hp) will be less impressive, but still a nice change of getting more power? Or is the change too small and just look for a 2.5si (218hp) or don't play it soft, get a 3.0si?

If you drove one of these engines, what is your personal feeling about the difference. Thanks…

i'd say the 2.5 177hp will be too small, my mate has one and it's not much quicker than the 2.0

Hmm, some people say there isn't alot of 'real world' difference noticable between the 2.5 and 3.0? Does that make the 3.0 and 2.0 similar? I guess not.
 
I've driven the 2.5si (which is what I have), the 3.0 and the M. I could tell a difference between the 2.5 and 3.0, but not enough of a difference to justify the extra monetary expenditure (for my budget). Of course, if I could afford it, I'd be driving an M, but luckily for me if I want to drive one, I'll just slide on over to ovrkll's house and drive his :D .

It really just depends on what you are willing to spend. They are all wonderful cars, I don't think you could go wrong with any of them. Just remember, no one pays your bills, and just when you think you have the baddest car out there, someone else has one badder :thumbsup:

you'll definatey notice the difference in a 3.0 especailly from the torque when you're picking up at low revs. If i didn't do as many miles in my job I would have got a 3.0 no question - but then i'd have to decide between a roadster or coupe!

6 gears helps the 2.0 but it is busy if you're trying to hustle along keeping up in the power.
 
I drove the 2.5Si and own a 3.0i now, and I'd say over 4500rpm they both feel about the same.

Remember the 2.5Si has 10% shorter gearing and 500rpm more to go at though.


If a 2.5i never gets onto that higher power plateau that the 2.5Si does over 4500rpm, then I'd avoid it if having a decent punch is important to you.

I'd just get a 3.0i if a 3.0Si is a bit too expensive for the budget you have. I think it's the perfect engine really, just enough so day to day driving fairly briskly doesn't need lots of revving/shifting, but without having so much that you can't use all the revs without smashing through the speed limit within a few seconds.

Of the 4, the 3.0Si has the most power, but you have to sit in the car and drive it. Buy what you can afford and what you like. They're all fun to drive! :driving:
 
In reality there really is no discussion, the 3.0 has absolutely all bases covered really. Not only do you get the explosive acceleration and throttle response, you also get the engine note to match. I'd conciede the 2.5 sounds good, but it just lacks in all areas compared with the engine it's based on.

Not only that, being one of the world's lightest 6 cylinder engines, the 3.0 is also incredibly economical considering the performance. I average 10.2 l/100kms in my 3.0si Coupe, with the majority of my driving being in the heart of Brisbane. When I drive up to Noosa on weekends it ducks in to the very low 9s on the highway. Very impressive for such a potent motor.

Interesting, the words I typed after this never showed up. Well here they are!
I agree with this guy 110%. But like others have said go with what you can afford, but test drive all of them in your price range and decide which one is right for you.




Besides, studies have shown that is no real world difference :poke: :fuelfire: in engine sizes. The link to the study which was performed by our very own and supremely talented Z4-forum.com members :ilz4f: is here. Enjoy the read, there is a ton of good information. :popcorn:
 
When I was choosing (and this is me personally), I was only looking at 3.0 litre cars. I would have preferred to go older to have the 3. In the end I was in the lucky position to choose what I wanted, but if was 5 grand down, I would have simply gone for an older 3.0, rather than a newer 2.5.

In the real world the bus is the best option - better for all Humanity - Of course, if you've got zero stewardship for this planet (like me - I'm waiting for the Borg), you go for the M and punch as much fuel through it as possible :thumbsup:
