Keep meaning to get round to doing a thread on this, but a couple of weeks ago I sent my Z4 back to BMW to have an troublesome alarm sensor replaced, and remote roof reinstated. For what turned out to be 5 days, I had this to play with...

The only flappy paddle gearbox I'd previously tried was in a 360, which wasn't nearly as much fun as the manual version, but that was only for a few laps, so as I was going to have this for a few days, I was glad I'd got the DCT, so I could give it a proper try. Everyone seems to be raving about these boxes, be it DSG, SMG, DCT, or PDK, general consensus seem to be that the new dual clutch boxes are a real step up, and as everyone seems to point out, they're quicker to change gear than a manual.


First impressions

From the outside it looks the part, although I'm not a fan of the light coloured kidney grills. Inside is awesome. The optional white extended leather against the piano black trim looks fantastic. Much more grown up than the old one. <3 I-Drive.

Now to figure out how to get the damn thing going. Stamp on thin air with left leg, then press the start button. Not interested in auto mode, so we'll knock the stick accross to sport, and fiddle with the sport settings. Sport+ is the highest of the three settings, so we'll have that. DSC light comes on, but I have little to no talent, so we scale back to normal sport mode. Gently on to the accelerator, aaaaand nothing. Bit moooooore throttle and the turbo kicks in and we're away. Sport mode doesn't equal manual, but a quick flick of the right hand pedal sees to that... Sorted.

Coming up to a roundabout, so stamp on thin air again before changing up from 4th to 6th as I apply the brakes. No idea why, but for some reason the left hand paddle does exactly the same as the right one. It seems you need to press away on either paddle to change down, and pull back to change up. Don't like that.

On to the motorway and it's much quicker than mine, I'm doing 120 and hadn't even noticed, so I back off, go up to 7th, and look for Cruise Control, which it dosen't have. Don't like that.

One truck tries to overtake another, and the fast lane grinds to a halt while someone else tries to over take at bang on 70. After what feels like an age, traffic clears, so with a clear road, I drop to 3rd and go for it. Or rather I don't, because the ******* gearbox hasn't sorted it's life out yet. Don't like that.

External noise is noticably different. I think there's less wind noise, but more tyre noise, very odd.

Off the motorway, and with heavy rain down to a couple of spots, time for the roof to come off, which takes much longer than mine, albeit not as long as it takes for the seats to heat up, as there's no heated seats. Dual zone climate control, but no heated seats or cruise control. Why?

It makes a cracking noise with the roof down, but in a completely different way to mine. You'd never guess they were both straight sixes, as this has a more, engineered, more processed sound which on occaison has the same quality as an Italian V8.

And that was pretty much it. It's faster, but only when the gearbox (which I still hate) gets it's act together, which often means it's only noticeably quicker at license losing speeds. The gearbox stops me thrashing it to within an inch of it's life. I can't wring it's neck like I can with mine. Even in sport mode it always changes up 200rpm before I'm ready to. Very fustrating. More grown up, but not as much fun. Feels more of a GT than a sports car. More 6 series cab than a Z4. I don't care that it is faster, because it doesn't feel like it's going as fast.

The steering wheel is much chunkier than mine, and very nice for it. The seats are much more supportive, but not as warm (Grrr!), and the pretty interior as a couple of dirty marks in places, while the piano black trim has a few light scratches in. Very pretty, but after only 2500 miles, you have to doubt the longevity.

But you get a 10(!) number plate, and for this you are expected to hand over £44k, or late thirties and the keys to mine. A 2003 3.0 manual Z4 with 97k on the clock is far from the last word in driving pleasure, but it is far, far more than 20% of a 2010 sDrive 3.5i DCT.

Which is something of a nuisance, because unless a manual gearbox transforms the new Z4, it's a potential replacement to mine scratched off the list.
 
How did you brag a Z4 35i as a courtesy car. I always get handed low-end 1/3 series.

I mentioned that Simon had bagged one on a 4 day testdrive, and gave a shortlist of potential next cars I was considering.

The guy who booked it apparently set an e-mail to sales, who didn't respond.

The car went in, and I finished up with some off road Nissan Shed (Adventura?) for a couple of days.

I was having a service done, and reported issues with a squeaky window and the alarm going off.

They replaced the interior sensor, but when I locked and unlocked the car, the indicators didn't flash. I mentioned this as I'd started to just lock the car with the key, and the indicators didn't flash, and the alarm didnt go off (I figured that meant the alarm was armed?). They brought the key back and remote roof didn't work anymore.

The ditzy service assistant palmed me off onto the service manager, who promised me he'd find someone that could reinstate remote roof (apparently they can't do it due to H&S).

I was on leave the following week, and wound up stranded in the middle of a cornish valley while the alarm had apparently been going off (for the fourth time since it'd been fixed), as the battery was flat.

I expressed my discontent to the Service Manager when I got back, and pointed out that no-one had got in touch about a potential new toy...

A week later I had a new toy to play with... :D
 
I like your reviewing style :D. Not having cruise is quite odd however.

Though yeah, how'd you wangle a Z4 35i? I swear all BMW here ever give out is 320Ds :(.

Not quite as eloquent as some (read:most) no doubt... :o

I'd actually quite like to try a 320D. w/~170bhp and 50mpg, an ED wagon makes a credible mule to abuse either while keeping SFTW or in a few years when they're cheaper to buy, as a cheaper means of doing my 30k commute.

The manual box was a disappointment I found and was hoping the 7sp DSG would be better.

However it was effortlessly quick, although I can imagine it felt a lot heavier than the 'old' Z4? Its a 1600kg car, it's definately more of a GT car

I found it lazily quick most of the time. It didn't reward working it hard. Some times it'd take off like it's arse was on fire, while at other it seemed to bog. I'm not sure how much of this was the driver, the turbo'd engine, or the gearbox.

The weight was one of two things I forgot to mention. I find myself in a difficult position with my current steed value wise, and was relying/worried that 30% extra power would really tell when I got back into mine. The reality was that either the weight, the turbo'd engine or the gearbox blunted the performance differnce in 2 figures to negligable levels. It's streets ahead above in 3 figures, but I've always had more interest in feeling fast than going fast...

Hmmm, dissapointed to hear what you thought of the DCT box. I took out an E93 335i DCT last year and enjoyed what I initially found but you dont really get to know something on a quick test drive. What you describe is exactly what I hate about most autos.

That's an interesting point for two reasons. First, I thought you'd like the car. Certainly the interior, but also the grown up feel. Secondly, that's exactly what it is, an auto. A non-torque converting, more economical, more involving auto. And that's fine, but with the marketing BS around it being quicker than a manual, and more concerningly being exclusively available in the M3 CSL and the 458 Italia, I had it down as being an evolution of the manual gearbox. Rotty likes his kit, had swore by his M3 SMG. Gibbo isn't shy whn it comes to cars, and loved SMG i his CSL. I figured my indifference was based on a few laps in an early implementation of the technology, but it isn't. Consequently the De Le Coure video and the Housey thread re the GT3 RS do nothing to reassure me that my dream end game is Italian afterall.

I don't doubt that much of my problem is my lack of talent (felt like a god winning my APCC heat, then got completely and utterly owned in the final), but my what remains of my ego insists that much of this ability can only really be appreciated on track. I haven't been on track, and if I did it wouldn't be in anything of value, so I can park my inability to afford that level of kit behind the pretence that I wouldn't have either anyway. honest.

a) Disappointing review, but understandable as you'd assume the new Z4 would be a logical upgrade from the current one. It may still be as by the time I lose enjoyment in my 03 I think i'll be old enough to want a bit of comfort.. but also have the top down.

You made it into a Z?! Ignore the fact that 'made it' could be taken to be pretentious, I've done a DiamondMark, and had couple of beers... I knew you'd been after one forever, but didn't know you'd taken the plunge...

How are you finding it? Was it worth the wait? What spec/etc?

The upgrade thing is difficult.

I couldn't understand the obsession this country has with softtops given that both sunny days a year are invaribly during the week when you're in the office. But it's so much more than that. If you go fast enough, you don't get wet in all but the most miserable conditions, and the warm arse/burnt face/frost on the ground combo takes a lot of beating.

I took a chance on the Z as I was originally looking for another 330Ci Sport (albeit 'fully loaded') having binned my first one. Headrat mentioned he was selling his, which was when I realised that the E85 was an E46 that had traded rear seats and a roof for rattles. The rest is history.

I've read Scuzi and Fox talking about the harshness of the Z4M, and has all but discounted that, as while I like an involving drive, I'm slowly growing into a fat businessman and subsequently need a German interior to trim my waistline and reinstate my original hairline. I figured the new Z with it's hard top roof and gorgeous interior was the answer (albeit in a few years when people started to realise that £40k is Porsche (one syllable!) money).

The other issue is fuel economy. My Z4 3.0 books at ~30mpg, and I get ~27mpg. The riduclouslylongandobscurelynamednewone also books at ~30mpg, but I only got ~22mpg (according to IDrive) over the course of ~500 miles. Aside from the cost, range is an issue doing 30k a year.

Given that I didn't rate the new Z, and the fact that there's not a huge choice of 6cyl 2 seaters, I'm either back to the Z4M, a 3.0Si or a 987S...

The steering makes me a sad panda, mind - it shouldnt be possible to have an executive saloon and a roadster from the same manufacturer and it be the executive saloon that has the considerably better steering feel.

<3 Fox... This I completely agree with. Steering wise (I'm reluctant to call it feedback for fear of giving myself too much credit), I agree with Tommo's assessment, the E46 is better to drive. The problem is that with the E85 you can take the roof off in traffic and enjoy the sun (read:clouds), whereas the extra driving bit the E46 gives is only applicable 10% of the time.

The obvious answer would appear to be the E46 Convertible, but the one I drove was awful, it shook all over the place. It almost felt like someone had taken a coupe and cut off the roof...

Trouble is a Z4M will cost me £10k and my keys, while giving worse economy/range. The 3.0Si is better fuel wise, but costs the same as the +80bhp Z4M. The 987S is appealing, but I don't know enough about the boot, and the fully specced 3.4 I found was £24k... ouch...
 
I did 600miles in 4 days: Motorway, A road and welsh country lanes. Average was 28MPG which was really impressive for the engine size and weight.

The manual was just notchy from 1st to second, however its probably me being spoilt by the S2000 change. On reflection -I think the same about getting it off the mark, it could be heatsock related. I had it hooked up perfect once with a smooth gearchange too, and that was the first time I tried out of the M6 toll booth. Any other time was a bit 'boggy' but it was 25C+.

I agree on the bit about it not wanting to be driven hard, however it didnt really suit the character of the car. Definately a GT - the S2000 felt like a house fly when I got back in it, the interior did rather dreary though after the White Nappa in the Z4.

Definately a great car for a all purpose daily car, however £45k would be hard to justify.

I tend to cruise at ~95 when I can, which doesn't help fuel wise, not least from a comparison perspective (?) but if we were talking like for like, do they lie as much about the auto boxes not sapping consumption as much as they do the car as a whole?

I don't mean this disrespectfully as both cars are very much in the same sector, but with the miles I do, I don't think I could live with a screaming 4pot without my toy-laden interior.

As a weekend toy (possibly with supercharger?) that noise would be epic...
 
Strange box, I would have thought Sport+ would hold the gear.

I only tried Sport+ for the .08 seconds it took me to realise that my computers wouldn't step in and alter physics when I ran out of talent...

After that I was back to normal sport mode. The DSC light went out, but the GIRL light came on... :(

I think the Z4 handles really well - it's certainly fun to drive and chuckable. It just has two flaws - the steering and the suspension. It's so stiff that if you take it over a B road you can't push on because its too skittish. It's much better without runflats, but it's still not perfect.

Ah yes the suspension! The new one was better at speedhumps (despite the 19s/runflat combo over my 108s/F1s) but seemed to skip pot holes...

One thing I will say is that the fuel economy on the Z4 is brilliant for what it is. It does 40mpg on a run, which is staggering!

h8 Fox! :(
