Z4MC vs 35i

Weight is Everything.... im almost certain a stock z4m will keep with a 35is.... once higher speeds come into play i reckon the is would get it.

then add a few corners in and then its goodbye mr e89.

I would say in the real world of gear changes the DCT is worth a second for every gear change i.e. 6 seconds to 155mph and that is without the overboost. :)

Whilst I don't doubt that DCT has benefits in terms of quicker acceleration over non-DCT equivalent models, I think that's considerably overplaying the DCT benefit Kryton. As an illustration a Cayman S has a 0-160kph (99mph) time of 11.4 seconds according to the manufacturers own data, with PDK it is 11.2 and with PDK & Sport + it is 10.9. So only 0.5 seconds in 100mph.

The Z4M will accelerate from 0-140 in 25.0 seconds (E92 M3 21.9) and 0-150mph in 30.0 seconds, (E92 M3 26.5). There is no way on earth a 35iS will do 0-150 in 24 seconds. The only reason the 35iS has a quicker 0-60mph time is because it has a launch control facility. Don't forget that you need quicker gear changes because you are having to upshift at 6000rpm (versus 7900 for the M).

Apparently...

The average manual shift time is 500 ms - 600 ms
A 'slow' change is anything over 700 ms
An E46 M3 with SMG II is about 90 ms
DSG style gearboxes apparently manage 10-12 ms

So DCT is virtually instant, but the actual time lag isn't that great. Differences as small as that only matter in Formula One and arguments in the pub after two pints. The weight of the driver is probably more important
 
I think the best way to settle this is that 2 members here - one with a Z4M the other with a 35is give me their keys and i'll race both and decide?!

Personally in the real world the DCT will be much faster then an "average" driver, where the DCT will get it right everytime and even a good driver can have a bad gear change... but personally i still prefer a proper manual.. even if it is slower wheres the fun in driving the same controls as a go-kart :fuelfire:
 
I had a race from stand-still with a 335i. I was in my 3.0si coupe. I got in fornt of him at first but obviously was not pulling away from him at all. The 335i is one of my favourite cars. Would love to have a go on that engine!
 
Well I'm willing to give it a try in my 35i (not an S) and see what happens - anyone can have a bad start from the flag going down - and maybe against a manual the E89 should be able to do it....

London Meet - anyone want to challenge me? feel free.....

These are manufacturers figures

Exactly...the manufacturers figures if anything will exaggerate the benefit of DCT type gearboxes because they add a few £k to the price of the car... :fuelfire: :rofl:

Kryton - bring that 35iS along to the Lakes meet....if it beats the M's from a standing start then a nice glass of claret comes your way.... :thumbsup:

Perfect example...... DCT really doesnt make a night and day difference.... from a dig a stock z4m will beat a stock 35is for sure...... DCT is great for keeping your hands on the wheel during cornering but DCT boxes are VERY heavy, the e89 is Very heavy, the maths are simple, take a lighter car, with the same power = slighter quicker car, you cant beat the laws of physics. The 35is also has bmws terrible idea of the push pull paddles which are a complete waste of time, luckily they've sorted that issue and added proper paddles on subsequent models.

i would love to see a stock z4m vs 35is, but i already know the outcome....

the quote Re DCT being good for 6 seconds to 155mph in the real world has is one of the most exaggerated things ive read in a long time.

Think of how long it takes from lifting your foot fast off the accelerator, changing gear to pushing it flat to the floor again, a minimum of 1 second I would say. :driving:

I think 1 second is way too high. I'd say 1/5 sec or less for a fast manual gear change
well... 2-3 maybe slower than 1-2 or 3-4
I'm no racer, but 1 sec is ages :D

I've not driven a car with paddles yet but they certainly make it easier to concentrate on my ring record in gt5...formula gran turismo is good for sub 6.20 a lap...would like to try paddles on track in real life!
 
The Abarth has the paddles, great etc. However, I do "miss" the gearbox action as it feels a bit like an auto box ...

My old SMG zed was sweet on full attack, but anything less than that and it was a stinking turd.

SMG / SSG in the Z4 and 330 was awful though. SMG II is much better, DCT quite astonishing...though perhaps too far the other way? It's so smooth and so fast, it may as well be an automatic; the gear you are in just becomes a number on the display, it doesn't feel like a manual at all
