Hi guys. i'm looking to buy a E85 Z4. I've been doing my research but I can't find any info on cars with the sport button compared to without. (Either 2.5 or 3ltr).
Basically, opinion varies but the sport button makes the car a bit more dynamic. Weighting the steering and crisping up throttle response.

My thoughts are (hopefully) that cars with the sport button are a bit more civilized, and easier to live with on a daily basis but if you feel like it you hit the sport button and sharpen up the drive.

What i can't find is how the cars without the button feel. I'm hoping they are always in the sharper setting but I can't find any info.

I know, the best way to find out is to try both but maybe someone else has driven both back to back?

Cheers, John.

Hi John,

I've only had E86s, and both had the Sport button. But to be fair I never bother with it - maybe it's just me but I can't tell the difference. rolleyes

I think the cars without it are set to the standard settings, rather than the "Sport" ones as they are usually lower spec models.

Anyway, here's a link to a discussion where it crops up:- https://z4-forum.com/forum/viewtopic.php?f=2&t...

You'll find lots of useful info on that forum.

Good luck with your search. thumbup

There’s no difference in the cars whether they have a sport button or not

They all have passive suspension

What will affect the drive is whether they have standard or MSport Suspension

Personally, on a long run I don’t use the sport button .. it’s more relaxed with it off

On the back roads .. it’s the first button I press .. ok after the one that lowers the roof smile

IIRC all 2.5 and 3.0 cars came with the sport button; only the base model 2.0 does without it. I looked at several 2003 - 2006 2.5 and 3.0s before I bought mine a year ago and they all had the button.

Yes, passive but Sport Suspension was standard on the 3.0, not the 2.5 pre facelift.

Exactly. Not forgetting to don your sunnies first (it's the law - day or night) smile

On the auto the sport button also means it changes up at higher rpm. So pressing it, or by moving the lever to the left, you can prompt a down-shift.

I know there are different suspension settings depending on year and model .. I was just illustrating that they are all passive

I stir mine with a Spanish gearbox in the hope it clerks the sky blue smilesmile

Yes, I was just making sure the OP knew to check.

I just had a quick look at my period brochure, and facelift 2.5Si and 3.0Si models had the "Sport" button whereas 2.0s and the 2.5i didn't.

As others have said, they all have passive suspension but facelift "Sport" models have a lower and stiffer "M-Sport" suspension set-up than SE models - plus the way better "M-Sport" seats.

Thanks for the replies guys.I didn't know about the suspension.

Looks like the car is the facelift 2.5se so I'm guessing the 177hp model which I'm not so keen on as the 3ltr is a fair drop in power never mind 177bhp.

Is it the 177 that can be remapped to 190? I've read that changing to the 3ltr manifold takes the 2.5 up to 3ltr power. is this right?

Do the 2.5 and 3.0 sport models have the same suspension as the Z4m?

My son has a Z4M Coupé with a sport button. I cannot speak for non-///M cars but on his it sharpens the throttle response markedly. If you want to heel-and-toe then the throttle is dull without sport on, but with it on H&T becomes practical. There seems to be a dead few millimetres of pedal movement without the sport ON. No effect on any other aspect of the car though - steering is non-electric on ///M cars.

Fly by wire throttles are awful things on lively engines in my view. I have Z3 2.2 with FbW and it is very hard to manoeuvre smoothly because the throttle is somehow disconnected or has a delay. It is easier to drive my 'real-cable' throttle Westfield than the FbW Z3.

Hi Johnny,

Pre-facelift 6 cylinder models were 2.2i (170 bhp), 2.5i (192 bhp) and 3.0i (231 bhp) with just one trim level. AFAIK M-Sport suspension was an option, so there will be some around that have it but probably not many!

Facelift models were 2.5i, 2.5Si and 3.0Si. The 2.5i was basically a lower powered (177bhp) model to replace the earlier 2.2i. But from what I've read there is no easy way to get them up to the 218 bhp of the 2.5Si. There's definitely no way of getting them up to the 265bhp of the 3.0Si!

But facelifts came with either SE or Sport trim levels. The Sport got M-Sport seats (very desirable, and expensive even used), M-Sport suspension (so lower and stiffer) and a thicker M-Sport steering wheel (plus an anthracite headlining in Coupes). But it gets confusing because all those features were on the options list for the SEs. rolleyes

So you really need to get the VIN so you can check the OEM spec. But now these are all getting on in years plenty will have had new springs, shocks, etc. so may have had replacements to either spec - regardless of how they began life!

The M Models are totally different - I think they use E46 M3 suspension parts and they have an M-diff, hydraulic PAS (instead of the electric PAS non-Ms have) and they don't use run-flat tyres.

Good luck. thumbup

Iain.

Depending on your budget, I am selling my 2006 3.0si sport individual. It has the sport button and as many extras as you can throw the book at :P no issues with power here, it's the 265hp variant of the N52!

I’ve had mine for 5 months now and have enjoyed every minute of it. I wouldn’t bother with anything less than the 3L engine, it’s a wonderful lump. For around the 4K mark the roadsters are currently amazing value for the performance

M Sport suspension was standard on the 3.0, an option on the 2.2 and 2.5. I'm not sure about the 2.0, which replaced the 2.2 @ 2005 iirc. It had stiffer springs and a 15mm lower ride.

M Sport seats were also an option.

By coincidence I was looking at Z4s last night.

Now that the Touring situation is sorted, need a daily for work. Nothing fancy, <£5000 and they seem like a more reliable (and cheaper) alternative to a Boxster.

2.5 or 3.0 seems sensible.

From the reading I was doing yesterday, they started off with the M54 engine and then swapped for the later N52?

When was the facelift? Is it worth keeping an eye out for one of those?
