6 or 4

i'd much rather have a 2.0 4 pot turbo than that god awful 23i 6 pot! They are slow as fook! My mates got one a nice low miler, its alright if you wanna sit on the motorway cruising about but for a chuckable sports car its very lethargic. if it was a 35i that was on offer though it would be a no brainer - six pot all the way.

The remapped 28i is a really good car. Mine mapped to 303 hp with 378 ft.Ibs of torque. In ideal conditions you can get 40mpg on a long journey. It feels pretty quick with the 8 speed auto . Could even be sub 5 secs 0-60. It is the sensible choice( its not that sensible though ).
I really miss my 3.4S Boxster though. I like cheaper tax better economy but a 6 cylinder has that extra character. Tough call between 4 and 6 pot.

Thats a bit harsh
We have had ours for 4 years now and yes there are definately faster models around but it isnt what you would call "slow as fook"
If they were as bad as you say Im sure we would have gotten fed up with ours and changed for something with more grunt.
Dont think I have had a problem keeping up with others on forum runs either, maybe Im wrong and was holding people behind up
If we were looking for a fast car I dont think BMW would be top of the list.
For an open top car I dont think its all about speed anyway.

Sorry if you found it offensive! I just remember being massively underwhelmed when I drove my mates. I've had 7 z4s now all of them either 2.5i or 3.0 e85s an e86s so I just guess I was expecting it to be at Least as quick as the e85 2.5i I just found it really lethargic on pick up and didn't have the torque to accelerate when at low speeds in higher gears! Like I say only my opinions, they are all like arse holes we all have one

I didnt find it offensive, its good to hear others opinions even if you dont agree with them.
I think the E89s 2.5 litre engine has less power than the E85/86 2.5 litre engine, that and a bit more weight will make it a bit slower.

Jamie, is that why you was doing an Danny Dyer impression @ Santa Pod

The remapped 28i is a really good car. Mine mapped to 303 hp with 378 ft.Ibs of torque. In ideal conditions you can get 40mpg on a long journey. It feels pretty quick with the 8 speed auto . Could even be sub 5 secs 0-60. It is the sensible choice( its not that sensible though ).
I really miss my 3.4S Boxster though. I like cheaper tax better economy but a 6 cylinder has that extra character. Tough call between 4 and 6 pot.

Hi, are you sure you have that torque figure correct & it's not measured in newton metres? Got a rolling road print out you could post with some numbers on it?

Its probably quicker than mine - with that torque

[Smartbear]

I don't remember seeing that, must be my age
That's a seriously high torque output, got to be sailing close to the wind

I had a 123d for over 6 years before I bought my first Z4C - what was I thinking when I bought that?

I got a cheap Mazda 323f 1.5 litre as a daily for cheap RFL and economy, but after 6 months had to sell it as it was so gutless!

So with my sensible head on I bought an E46 325ti as a daily so I could have straight 6 petrol power all the time.

OK so the OBC on the 123d showed an average of 48.7 mpg, but my Z4C is showing 33.2 mpg and my 325ti is on 34.9 mpg so petrol is hardly a disaster!

You won't be surprised if I say 6 is the only way to go IMHO. A straight 6 is one of the unique properties of a Z4.

If you want a chuckable sports car why would you buy an E89?? The E89 is a cruiser, don't get me wrong the handling is alright but a Cayman would be a far better choice.

I wouldnt buy one, just saying, a z4 (FOR ME) is meant to be a back road blaster which is a thrilling driving experience - the E89 is just not. (Again, only my opinion before anyone cries!)

[Twin Turbo]

No crying lol

The E89 with MSPORT suspension is pants (My opinion) - I felt totally unsettled doing 90 miles an hour down Craner curves - and the amount of understeer is immense. However, for most E89 drivers, I believe the suspension is adequate - as they don't drive the car vigorously.

It was built for the USA market - as a GT and cruiser.

However....

Slap some good coil overs, change your tracking, decent tyres and you have a capable car. Admittedly not as great as a boxer - and you struggle to find the limits of the car on UK roads. I only found limitations of the E89 on track.

But been on a few drives with E85/E86 and not had an issue, with entering or exiting a corner.
