How fast will a Z4 actually go?
- Thread starter DaveZ4C
- Start date
Same runway , same result 2x times.
Saw 148+ before I ran out of road and had to stomp the binders.
I saw no difference between 5th and 6th in the speed runs.
Sport shifting madee no difference. (automatic)
It just took a long time during the run for the tranny to upshift to the top gear and limited the end of run speed increase.
I am sure that 155 mph is the top for my Z4 3.0 given a bit more room.
Unless there is a way to select an alternate shifting method to push the engine into a higher RPM pattern for the run.
I will say that 130 mph was smooth and slow after hitting 145+ several times.

oke:There are several of us that drove our stock z4's at an undisclosed location at which we have been up to 138 MPH. One of the crowd had an M, and he hit 155 ,,,, Mine is an 06 3.0, 138 with top up, 125 with top down. It was a straight and level run, out of the way from any traffic.
The feeling "fast" thing is really evident to me when i drive, and I'm sure it's just an illusion related to being close to the ground, the engine sound and tourke from the six speed. When i get in my wife's A-6 i find myself speeding without realizing because it is soooo quiet. Whatever the reason the Z feels like an extension of yourself and delivers a really unique driving experience. One man's opinion!
Considering testing this here: Laughlin Rd, 4 mile straight/level stretch

I run this road all the time and have considered this already due to how level the surface is and how well maintained the road is. I'd probably need a little time to be comfortable over 140 which was the fastest I've done previously (Corvette, decommissioned runway in Texas). Set some cones up at 3am Sunday morning and take my time. I'm assuming I'll hit the 155mph limit and start research how to remove it.

I had my 2003 3.0i to just over 145 once for maybe 5 or 10 seconds....
I could have gone faster but I was catching up with a car and did not want to pass anyone at that speed.
The video below was posted by a member of the old Z4um.
I believe his name was Mark who was a USAF officer stationed in Germany.

I've seen 155 on the speedo,roof up,fast enough for me, and fast enough for the M5 behind not to get past....... 
Saw 150 mph in France in June on the motorway,felt really stable even with a boot full of luggage. Not sure I'd want to go any faster, it's pretty scary at those speeds on public roads. :driving:

If your caught speeding in France I thought they rape you for the fines? I read about one guy on the way to Le Mans in 2010 who got caught at 160 and lost his car as a result
