Exclusive: BMW F01 7 Series Gets 8 Speed

We were all happy with the 6 speed transmissions that appeared a few years back for performance and efficiency. Then MB released a 7 speed auto making the 6 speed look obsolete and BMW driver’s green with envy. This past year Lexus toted they had the worlds first 8 speed auto. This was an interesting development as BMW did not even have a 7 speed. The 8 speed Lexus offering is only available in the land yacht sized LS because it too (like the LS) is a bit too large for other models in the brand’s line up. With the introduction of the next generation 7 series BMW will launch its first 8 speed gearbox.

In order to keep up with the Jones’ BMW has had to think a bit outside the box. Our sources indicate that the transmission BMW will utilize takes up the same amount of space as the current 6 speeds and will not use additional components. This has been made possible by a completely new transmission concept. We have learned that it utilizes four planetary gear sets and five transmission clutches. Two transmission clutches are unlocked per gear, thus resulting in greater efficiency and a higher overall transmission ratio.

It is touted as being smoother and will reduce fuel consumption by almost six percent; way to go Efficient Dynamics! Since it is the same size as the current 6 speeds, a larger hump or other invasions into the passenger cabin space is not necessary. The gear selector will also return to the console from its previous stalk location; a well welcomed change for many. BMW had explored other options but testing indicated that an 8 speed is the most efficient form of transmission because of the optimal use of gear ratios, weight and size. 9 and 10 speeds boxes actually showed a decrease in efficiency and additional size constraints.

This transmission is modular in design so it can be used in various applications. This will make it available for use in Hybrids and X-Drive vehicles, which the 7 Series will feature. This transmission should be available in all varieties that BMW will offer the 7 series in, allowing BMW to reduce costs associated with different drive-train combinations.

This transmission will make its debut in the F01 7 series to be followed later by the F10 5er.

The Lexus ISF also has the 8-speed Auto..

Way to go BMW!! ALWAYS one-uping the the one-uper!

Michael Apr 14th, 2008 Link

Brett- the ISF does indeed have an 8 speed but is a derivative of the Aisan unit found in the LS, it is not a new transmission. It is larger than a 6 speed. Unlike the Aisan unit the BMW will not have an issue with “hunting” for gears, this is due in part to the new system of gear changes.

Thank you for that bit of information Michael. I wasn’t sure what tranny Lexus was using in the ISF.
Regardless, I’m not a fan of Lexus and I’d rather have the 7-speed DCT M3 Sedan!

PS: The Model number cheat sheet has the ‘09 7-series as the F10 rather the F01.

Cris Apr 14th, 2008 Link

Actually, this is really nothing new. It has been known for a while that it will get the 8. What’s interesting though are other improvements that the 7 will get, something unique. You’ll find out soon when the info can be released :)

I’ll leave Manuel at home and opt for the manual transmission.

Sounds awesome and expected. I feel like this car will be a BEAST!!!! Just one minor detail. The 8-speed in the Lexus is no larger than the 6-speed unit that was used in the old LS430 as well as slightly lighter. Check the Lexus press releases as well as early reviews where it states this.

Cris, what could you possibly know that none of us know?

Brett, a few other things, I promise I will share soon. I just looked back and the first sign of the 8 Speed trans. was back in 2007 :)

And even if they did have other 8 Speeds. We all know, there is 8 Speed and then there is 8 Speed.

Michael, what is it about the new system of changing gears that will stop the gear hunting that affects the Aisin 8 speed?

We thank you for your input and would be the first to agree that an 8 speed was rumored a while back, but there were no details, just that there may be an 8 speed. We were not breaking the news of an 8 speed, we were breaking the details of it.

We are working on getting everyone information, not spreading rumors. There is a lot of stuff we have but can not confirm it with other sources so we are holding it back. If anyone ever has information they would like to contribute just send us an email and we will look into it.

thanks and we hope that you are enjoying the site.

We’ve verified that that is in fact incorrect. The 7er will have a optional xDrive (updated to a similar spec as the X6’s) but BMW is not (and has no plans to) develop an four wheel steering system.

It’s interesting to note that the transmission in the picture has provisions for a mechanical shift linkage for the 4 main operating modes. If this means BMW is getting away from the “joystick” electronic shifter found in the 08 5er and others, I welcome it.

About BimmerFile

BimmerFile is dedicated to bringing you the most interesting news, links and reviews related to the BMW brand and it's vehicles.

We believe in the old school BMW ownership experience. We believe in garage nights with a six pack and some friends. We believe in 2002s, in E30 M3s and E34 540s with the 6 speed. We believe in progress in both design and engineering but we haven't lost sight of what made the brand and its products great all those years ago. And yes, we believe in the manual transmission.

We long for the days of the wave and for the days of roll-up windows. Yet we love the gadgets on the inside and the xenons on the outside.

In short, we can't get enough of BMWs. This is BimmerFile.
