Is this a car that could replace my vx without me regretting it? I love the car but it is used more as a toy and i have a clio 172 as a daily driver. I feel it's a bit of a waste now having two cars and am contemplating replacing the both with one nice car. The Z4M seems a more sensible car to use everyday and i can't see much else for the money that comes close. The running costs for my two cars would probably be similar to running just an M so that's not an issue. Can i expect similar performance from the M as my mildly tuned turbo? (It's around 270bhp per tonne with 260ft lb of torque). The vx is an occasion everytime i drive it even after 3.5yrs of ownership and the performance is all that is required for road use, would the M have the same appeal? Any thoughts would be appreciated and if anyone has gone from a vx220 to a z4m your experiences would be good to hear and may help make my mind up.

the M, if my memory is correct, about 220 -230 per ton, so is slower.
it will also be better build / have more noise damping etc so will feel slower as there is less of an assault on the senses.
the up side is that its easy to live with every day and you could comfortable drive the length of germany at 140mph only needing to stop when the tank runs dry

I'm guessing the vx is fun in a darty balletic way. the M is fun in a 'i've just wrestled a tiger' kinda way

drive one, its the only way to see if it suits you.

That sentence should finish with, so is slower off the line, however once rolling and past 60mph the Z4M R will have the legs I think
Power/weight is a good performance measurement, but doesn't take into account aerodynamic drag.

I test drove VX a few years back, it was a great car but ran out of steam about 90mph

What sort of power is the VX220 putting out?

Sorry I cannot help. But I'm quite interested in this thread. I was thinking of suplementing the e36 M3 Evo with a VX220 turbo (which I could have as a company car).

Yeah i'd expect the vx to leave the m off the line as it's probably low 4's to 60mph if i wanted to kill my clutch! Am more interested in rolling in gear acceleration and if that would be similar, 60-100mph would be around 6 seconds in the vx. My car has approximately 250bhp and pulls strong in every gear, plenty of torque to not have to work it too hard either. If the m would even match the performance i'd be happy with that but it's not all about that, the m seems a proper drivers car and something i could use all year round.

Think you'll find the M fast enough then.

The M has 338BHP which helps punch a good hole in air compared to 250BHP cars, I tend to find most sporty car very similar below 60-70mph, but more power means the Z4M will pull much quicker at higher speeds.

You’re not going to come close to the intimate driving experience offered by the sublime feedback of the VX steering though, I actually said “lovely” out loud within a few corners on my test drive.

I would have thought the Z4M R would be slower ... and feel slower ... a modified VX is decidedly quick ! That said, the Z4M is quick .... but certainly doesn't feel mega rapid.

I had a TVR Griffith 500 which felt in a different league (performance wise) to my Z4M R but, as has been pointed out, above 60mph the Z4M piles on speed with little effort and is deceptive as it is a very linear delivery .

If it's your only car, remember that the Z4MR has an awkward boot, especially for things like suitcases. We fit a Le Mans trip for two, but it was tough. Something to remember if you use the 172 for moving things about!

Had a VXT (only Stage One mind), and bought the Z4MC. Didn't miss the VX one bit tbh. Admittedly I've made some changes to take my Z towards a more track-focussed machine, like the VX, but I don't think you'll be disappointed if you're looking for a little more refinement. The Z4M still gives plenty of thrills!

Had 2 Elise's and now have a Z4M Roadster which is going up for sale tonight frown

i loved the Lotus very very much but the only area you lose is steering feeling. The M is more than capable and the big bonus for me as I use mine all year round is the heated seats and the fact the roof goes up and down in 10 seconds which meant that i got a lot more roof down action at all times of the year.

The M will be slighly slower up to around 60-70 but after that the M comes into its own.

Where abouts are you based? if you ever want a look round one and a spin just give let me know - i'm in Bournemouth.

Thanks for the kind offer but i'm based in the midlands so it's a litle too far for me! Yeah i'm not expecting the M to have the same acceleration lower down but if both were doing say 40mph and foot to the floor i wouldn't have thought there would be much in it. Besides in gear acceleration is more appropriate on the road as there are not many ocassions where you need to hammer it from a standing start really!

Out of interest what are the most popular tuning mods for the Z4M to get a few extra horses?Any particular exhaust system for example? Also any idea of cost to get to say 370-400bhp?

This will cost quite abit of cash, IMO you could easily spend £5k and not even see 400hp.

yes

Not that it really needs it. Z4MR bhp/tonne is about 238 stock, which i find is sufficient on public roads in the UK....

The way it does 50-100 in 3rd for overtaking (on a track, obviously) is quite something.

Agreed, beedub has done it but it sounds completely mental. I'm not sure it should even go near a public road with that kind of power through the rear wheels!

Agreed. Not sure why you would need any more power on a public road. It really is rapid.

I am very tempted, going to give it some serious consideration. Not 100% sure on the styling, some angles looks great, others not so good. Also don't no whether i prefer roadster or coupe...decisions, decisions.
