Speed Test of M5 in West Texas

Took a trip to Lubbock last weekend for a bowling tournament. Here is the route I took.

https://maps.google.com/maps?saddr=a...mra=ls&t=m&z=7

The fun begins outside of Coleman on TX153 all the way to Sweetwater on I-20. Then you wait until you get out of Snyder on 84 and you are free to stomp on it to Post. Lot's of open road with no other cars and straight stretches to run it out.

The TX153 part has plenty of broad curves that can be taken at 100 with stretches into them that you can get to 150+ on. With AC on I was able to get 157 but no more. I had several miles of open road when I tried. I was the only car on the road at the time and I had to get to the middle and drive with both hands because it's not a great road for this kind of speed. I downshifted to 4th from about 95 in 7th and floored it. I took it back up to 7th gear but that is probably not necessary as I was only at about 4200 RPM in 7th. I was near 145 when I shifted from 6th to 7th and was at less than 5000 RPM in 6th.

I am pretty sure this is the limiter holding the car back as another poster on a different board used a gear ratio to RPM to MPH calculator to estimate my speed at 4200 RPM and 157 is about what it is. So that seems to me conclusive that for now, without a tune that eliminates the limiter, this is it for the car.

I made a number of speed runs from 90 to 140 and it's pretty quick between those two. I spent a lot of time over 100mph and it is a lot of fun driving the car that fast but you hardly notice it except for the curves. My overall average speed for the trip was 72mph and I got 19.6mpg. This average speed included going through a lot of small towns at 35-50mph and about 15 miles of the same around Lubbock.

Nice experience. Glad you were not stopped as I heard the ticket given for those speeds is see the judge in Tx.

Yes, no doubt, but the counties this road runs through are among the least populated in the state and the magistrate is at least 20 miles away from any point on the highway. No one is harmed in these situations and so there is in fact no crime. Arbitrary speed limits are just another way to limit freedom to do what you want without harming another person. This road has no posted speed limit for long stretches and the car doesn't register one either. If I thought anyone but me might be endangered by these speed runs, I wouldn't do them. I will take a picture of some of the stretches on this road the next time I am out there. In the meantime, here are some pictures of Culberson county which is further to the west. It has a population density of less than 1 person per square mile. These pictures were taken on land I own out there. The white things are capped water wells and the other picture is a gas well.

LOL. Great post. There is something hilarious about driving a new M5 over 150 mph to go check on your Texas oil/water wells. 'Merica!

Have fun and safe travels.

Nice post. Wish I was out there with you on the tundra, I'm very limited in where I can take my speed up in the Peoples Republic.

I was driving one in Munich two weeks ago and it pegged at 270kph.. 168 approx. Actually I think it was electronically limited to 268, but I hit 270 on a downhill. Autobahn helps.

Ard,
did you do this through the On Demand service from BMW Welt?
http://www.bmw-welt.com/en/visitor_i...and/index.html

I had a business trip pushed off and was thinking about doing that same thing.

If you did, happy to hear about how it worked out.

Thanks.

Yep. I had a meeting scheduled for the day, and it got moved to 8AM. I was done by 9AM and called to see if that had an M5 or M6 available (the online booking system showed they were booked). They did, and I was there by 10AM.

I spent about 115 euros on fuel....

Super easy to deal with, very straightforward.

Hah! That's awesome and I hope to do the same.

It looks like they have some nice planned routes depending on how long you take it.

Thanks.
