Among the future shocks to be shown at the rapidly approaching Geneva Motor Show, Land Rover will be displaying a nine-speed transmission it has been working with ZF to develop. Engineered for transverse – read: usually front-wheel drive – applications, the ZF 9HP will replace the six-speed transmission in the Evoque come 2014.

The three extra ratios add just a quarter of an inch in length to the case, yet it's 16.5 pounds lighter than that six-speed. The built-in benefits of the extra gears are better fuel economy and lower emissions, and the even lower gears possible will improve the Evoque's (never-used) off-road capability. The designed benefits are an adaptive shifting system that tailors the transmission to the driving style, a skip-shift function that avoids the need to move sequentially through the gears, and "Fast-Off" and "Curve" modes that take two different approaches to managing upshifts.

While it is the Evoque that breaks the news, it is rumored that the Dodge Dart will be getting this South Carolina-built transmission as well.

LAND ROVER TO DEMONSTRATE THE WORLD'S FIRST NINE-SPEED AUTOMATIC TRANSMISSION

• Land Rover announces new ZF nine-speed automatic transmission for transverse applications
• Increasing the number of gear ratios to nine will help reduce emissions and improve efficiency
• Lower gear ratios enhance all-terrain and all-weather capability
• Adaptive shift system matches and remembers customer driving style for a tailored driving experience
• Land Rover is lead partner on this project with ZF, a world leader in transmission technology


(MAHWAH, NJ) February 26, 2013 - Land Rover will demonstrate the world's first nine-speed automatic transmission for a passenger car at the 2013 Geneva Motor Show. The ZF 9HP transmission is designed for transverse applications, and is one of the most efficient and technically advanced transmissions ever used in a production vehicle. Land Rover is the lead partner with ZF on this project.

Increasing the number of gear ratios from six to nine will help reduce emissions
and improve efficiency. Smaller ratio steps also give improved response during acceleration, with improved shift quality and refinement. A higher top gear improves efficiency by lowering engine speed, which also improves comfort and reduces noise when cruising at highway speeds.

The 9HP is quite robust and complements the all-terrain capability expected of a Land Rover vehicle while delivering exceptionally high levels of refinement and efficiency. The lowest ratio in the 9HP is lower than the existing six-speed transmission and is designed for off-road use, towing, and on-road conditions like steep gradients.

Whereas the existing six-speed transmission makes downshifts sequentially, the 9HP has a skip-shift function for much swifter downshifting to meet rapid deceleration demands. If the driver requests a downshift when the vehicle is travelling too fast for the selected gear, the transmission will remember the request and make the shift when the speed drops to an appropriate level. "Fast-Off" mode measures the rate of throttle release, anticipates further requests by the driver for high power, then holds the gear if necessary.

The torque converter incorporates a multi-stage damper system for smoother pull away and improved refinement. An innovative adaptive shifting system matches the driver's mood within seconds, sharpening up during brisk driving and then seamlessly shifting to a more economical program when taking a more relaxed driving approach. Additionally, "Curve Mode," detected acceleration/deceleration forces, and pedal position all control upshift timing.

The 9HP is masterfully packaged and despite the extra three gear ratios is only 0.24 inches (6mm) longer and actually weighs 16.5 lbs (7.5kg) less than the outgoing six-speed transmission. The compact packaging is achieved by using a number of innovative design features: A new compact hydraulic vane-type pump, two patented dog clutches replacing bulkier conventional clutch packs, and a nested gear set.

Land Rover and ZF are on-going partners in transmission development; having jointly developed fully integrated transmission solutions in the Range Rover, Land Rover LR4 and Range Rover Sport. The new nine-speed transmission will be produced at ZF's Gray Court facility in South Carolina, USA.

      Transmissions don't get a lot of love but that's some serious engineering to pull that off.

      On a serious note, that\'s definitely an engineering marvel. On a silly note, this totally reminds me of the razor blade race, where we started out with two and now have a total of six blades on one razor (Gillette Fusion).

        There was a joke that went around about making the additional razor blade perpendicular to the others.

      Drive a Charger with the wonderful ZF 8 speed and then you can talk about it. These new transmissions have allowed the V6 Ram to have better gas mileage than a V6 TRDyota Tacoma. The new Grand Cherokee diesel can get 30 mpg with an 8 speed. Can't wait for the new 9 speed Cherokee.

        you know they could just make the upper gears taller and reduce the size of the rear end if it's all about the mpg

      Since the Evoque uses Ford's 2.0L EcoBoost engine, I wonder if this transmission will be used in Fords and Lincolns in the near future? However, I would not be surprised, if it does appear, that it will be first used in Lincolns, since I remember that Ford once stated Lincoln will be used to pioneer new technology. Also, I imagine that a 9-speed transmission from ZF would be expensive enough to limit its use to Lincolns and only the "Titanium" versions of Fords.

      It's not just rumored the Dodge Dart will be getting that transmission, it's basically confirmed. The Jeep Cherokee that is headed for the NYC autoshow will have it too.

      This is getting ridiculous. I'm wondering if a transmission that shifts more often because it has more gears won't wear out faster.

        It\'s called an \"Extended warrenty opportunity\" in the sales office.

      I'd be excited to see something like this work. I can't believe this is even possible-- I don't think anyone saw it coming. Transmissions are changing and improving just as fast as the rest of the industry. atransmissionrepair.com

      Too many more gears and the Democrats will want to hold hearings to ban high capacity gearboxes.

        Democrats? More like Republicans who want inefficient transmissions so we can use more gas to support the petroleum industry/companies who fund them. Corporations are people you know.

      9 speed! 10 speed! 15 speed! THIRTY SPEED! They really need to end this contest. Clearly, the CVT has already won. It has infinite speeds, guys. /s

      Engines that benefit the most from more gears are large vehicles and forced-induction ones. In either case, low rpms are how the benefits are achieved. If you rev a large vehicle or a turbocharged one, you will pay a high penalty in fuel consumption.

        Or even torquey diesel's, many of with reach max torque around 2000 RPMs up to their 4500ish redline. More gears equates to more fun with diesels, or so I would believe

      There better be "transmission insurance" available in case, ( inevetable ) failure of a ten thousand dollar transmission. This threat would positivly prevent me fron ever considering a used one of these!

      How many moving parts can you cram into one casing? I shudder to think what maintenance cost is on this thing.
