changing from 330d

hate to break the news but yes 
not much around with the torque figures of a 330d 8) just about to have ours remapped to "explore" its capacity on route to the med in june
the E89 is a much smaller lighter car though so you should still feel some poke under the throttle , never driven one though :wink:

Think you will find a 335d is quicker than a 3.0si. I found that out when I could not keep up with the wife in our tractor ! Lolab7 said:
Oh dear what have I done? I really wanted a Z4 for all sorts of reasons, and guess what?... they dont fit a six cylinder diesel engine, so to get anywhere near the MPG I went for the 20i thinking that the Z4 is a much lighter car than my 330d convert. I didnt test drive one because the dealer didnt have one in the complex. also as a farmer I get a bit fed up with tractor engines!
Tell him to remap it ! I have , bonkersab7 said:
Ive just change from a 330d e92 after 5 great years of ownership to an sdrive 2.0is and to be fair its more a case that the performance is delivered differently. Ultimately off the line theres not much in it, I think the Z will be slightly quicker to 60 than your 330d convertible but in gear acceleration is noticeabley down in the Z4. Not much can match the grunt of the 330d. As the Z4 revs much higher and holds its gears longer, it certainly doesnt feel as quick, but ive noticed that other cars tend to have fallen behind just as much when I push the rev counter towards 7k.
The Z is much more nimble and a huge amount of fun. If you accept that it delivers performance in a different way from your oil burner I dont think you'll regret it. There is of course always the option of the sdrive 2.8is but even this doesnt have the same in gear shove of the 330d

Just to be clear... There is no 2.0is or 2.8is, it's 20i and 28i. The only iS in the entire range is the 35iS.
I think OP that you'll notice quite a drop in power. The torque of the 330d gives the car a real surge of power, the 20i is as napastar says, much smoother mainly due to diesel torque/oomph. You'll end up thrashing the 20i to get any real performance. If you just want a cruiser though it will be fine.

Maniac attention to detail is spot re my error in the model classifications however I think the qualified opinions I was trying to get across were accurate.
Thrashing to 20i is rarely necessary and if economy is important the 20i or 28i are pretty good - currently mine is returning 38 mpg compared to 43mpg from the 330d on the same daily journey.

I agree they'll be similar in their drive, in fact the 20i will be superior in short bursts due to the DPF on a diesel. You'll notice the power drop though.
The reason I clear up the nomenclature on the models is because putting a . Between figures suggests the engines CC when in fact it's BMWs own made up designations.

my mums E90 330D feels way quicker then mine... and my neighbour has just gone and got a 20i.. which def doesnt feel anywhere near as fast as mine... no kick in the gut feeling on heavy acceleration... so i'd say you'll be in for some disappointment if you are are after something which feels nippy.
But the E89 looks a million times better then the E90.. so you win some and you lose some!

They are definitely a different drive. I was having a crisis of choice and test drove a 2.2 Jag XF diesel and the Z4 20i on the same day. I almost went with the Jag because it FELT so much faster, it gave the jolt off the line and when speeding up from low-revs to overtake on the motorway - the Jag felt better every time.
On my second Z4 test drive, I said to the rep with me that it wasn't as sporty as I was expecting - he told me I was driving it wrong. I was upshifting around 4000 RPM - why? Because the Jag I'd just come out of had its power in the 1500 to 2500 RPM range, and my turbo petrol Audi has the turbo surge in the 2500-3500 RPM range, so I was used to changing up early to continue the power surge. The 20i BMW seems to have its power surge in the 5000-6000 RPM range. Let it rev through before each gear change and it will bring a smile to your face. So I agree with some above comments - you have to 'thrash' it compared to a diesel ride, but the engine is designed to do that, so its not a bad thing.
The upside of this is that motorway cruising keeps the RPM below the turbo window, which gives the very enviable 40-50mpg motorway mileage. Now whether this is what you really want from a sporty roadster is another matter altogether, if pure sport was your goal, the 35is would be the answer.
Also, if you got the 8spd auto, you'll never acheive a sporty get-away from the Normal mode, with 8 gears to choose from and economy on the brain, it changes often and early. If you need to beat someone off the lights, stick it in manual and paddle shift your way to victory.

As said above, you need to drive it differently. No doubt the 330D is quicker, and pulls much better in-gear, but you need to let the Z revs round to 6000 before changing gear, if you want maximum power. Diesels have a much flatter (less peaky) power curve (and torque curve). 330D is awesome engine.
But it's not all about speed. Get the roof down, let the wind ruffle you - it'll feel faster straight away!

Just wondering which car is returning 38 mpg 20i or 28i ?
