Consultation Z4 sDrive28i

Fairly sure they don't have launch control
I think it's only the 35is in the E89 which has launch control.
The difference between the ///M135i and the 28i is one is a 3.0l, 6 cylinder, twin scroll and the other is a 2.0l, 4 cylinder twin scroll. Although both should be capable, the 28i is designed for good performance and economy. The ///M135i is designed for great performance and well economy isn't on the list. BMW will also want to ensure the engine doesn't blow up!

alanm474 said:But the BMW 428i has the same engine as the 428i and Z4 sDrive28i if you have launch control.
Sorry, in English please
Hi and welcome alanm474.
May I ask why launch control is so important to you?

Are you trying to say that the 428i has it? If so look here http://f30.bimmerpost.com/forums/showthread.php?t=986481 and you will see that this is only on the 2014 onwards model F series. Your enquiry is about a E series Z4.
It 'may' be possible to code it as suggested on the link but I'm not sure.

Launch control is absolutely worthless in the non-M BMW models since you can't specify the RPM for the launch.
It will just pin the revs at 5k and spin the tyres. Much faster to manually launch. I think with the slushbox you can hold it on the brakes in 2nd gear for the optimal launch but that isn't good for gearbox longevity.

Isn't a 330x 4 wheel drive so should launch well if done right.ronk said:A pal has it on a 330x d and I have to say it seemed to work very well.
No spinning wheels and launch seemed to be at a max torque level.
Having said that I can't see why or when I would use it!
Yes it's the 4wd version - the launch control was tremendous - I was very impressed by it but I can also understand the stress that the whole system must see.
When the car set off - I can only describe it as like an aircraft take off - just seemed like one great whooooooosh of power and acceleration. That coupled to an 8 speed box there just seemed no gap and the changes were not really noticed!
