Shouldn't the M3 more likely compare with the RS4 instead? :think:

It is definately going to out-run the S3 ...

emzino · Mar 24, 2007

I thought it was like this:

M3 = S3
M5 = RS4

and so on and so forth but just done some research and your right, it's direct competition with RS4 and Mercedes C63 AMG. My bad...

But it is a cracking car! It's a tough on between the RS4 & the new M3. Hmmmmm

DSGSport · Mar 24, 2007

I'm afraid not

As far as I am aware it is

1 Series = A3

3 Series = A4

5 Series =A6

7 series = A8

etc

414bhp out of a NA 4 litre? That's pretty special!

newbiecrg · Mar 24, 2007

What does an M3 has to do with an S3?

Give me an M3 anyday off the week....

Maybe next year....

Not quite as special as the new GT3...claimed 418 BHP from a 3.6.
Evo tested one at (I think) 427 BHP.
That's even more special...

But anything above 100 BHP/litre is special in my book!

I can't honestly see the V8 M3 and the S3 going for the same target buyers...
The M3 will be nearer RS4 money, if nothing else.

Ahh yes but 418 out a 3.6 is VERY special not just pretty lol

Emzino made a mistake. He's changed the title to RS4 has some tough competition.

Eventually we'll have to uprate the 100bhp/l threshold as better and better engines come out!

That's right so please stop pointing out the obvious :keule:

Hey no need for that. I'm on your side after you made a mistake thinking an M3 was a rival to an S3!

joost · Mar 25, 2007

Regardless of what the M3 can achieve, it'll still be driven by a complete ****@r!

I meant it in a sarcy way. Hard to show it when typing heh :arco:

normski · Mar 25, 2007

I assume you didn't look at the price of the M3 before starting this one?

But the S3 will certainly hold its own with the 335 and at £10,000 less.

Yeah, I think the M5 and M6 offer some stiff competiton to the A2 as well, think the A2 will struggle to keep up with these babies....

Lol, stop taking the **** now everyone. He made a mistake and I don't think we should punish him any more.....ok just for today give him hell, but come tomorrow......give him some more :jump:

But you saw the light...

Only kidding fella, I've nothing against M3 drivers, past or present - it was just an alcohol induced posting, my bad :sorry:

a3norwich · Mar 25, 2007

Hmmm, just a differrent light I think. Was getting a bit fed up with their dealers' arrogance. Seems I have swapped it for a different type of arrogance with my first Audi...

Have to say though, BMWs don't have creaky doors, folding mirrors that have a mind of their own, central locking/door mirrors/windows that stop working for no reason, door alignment problems, etc, etc!

"A characteristic of the car, sir..."

newbiecrg · Mar 25, 2007

what? complaining about Audi "features"?....

And you still ordered an S3?

I love BMW's as much as I have always wanted an Audi. We have some new 530's at work and the amount of piddly problems with them is unreal. Either a bad batch or standards are slipping everywhere.

a3norwich · Mar 25, 2007

Indeed I did! A moment of madness perhaps. However, I don't think there's such thing as a perfect car. They all have their problems! My M3 ownership wasn't without "entertainment"...!

I changed the title as soon as the 2nd post pointed out that the M3 isn't up against the S3 but theres a bug with the forums.

When I change the title, it only shows the updated title once the thread is opened and not when it lists the threads in the 8P section... :idea:

If you're talking about cop cars, you should know that police fleets are made up of lemons in weird specs that their first owner rejected.......

steve184 · Mar 26, 2007

mmmmmm M3 - my next car - prob old shape - love em

Completely untrue with the BMW's, they don't even bother putting the seats in em any more to make space for the armoury, factory built to order and spec including wiring looms etc. for lights, and allsorts, plus they have such an odd spec that no-one else would touch them before us.
