Volkswagen Literally Crushes Its 10-speed Dual-Clutch Dreams

volkswagen literally crushes its 10 speed dual clutch dreams

Three years ago, Volkswagen Group teased attendees at the Vienna Motor Symposium with juicy details of a transmission designed to take fuel efficiency to new heights among the automaker’s higher-torque models. A 10-speed dual-clutch transmission was in the works, it announced, promising mondo improvements in efficiency.

Between then and now, VW changed its mind. As it pursues a strategy of electric vehicles, wide-ranging productivity gains and, ironically, utility vehicles that could make use of it, the 10-speed has vanished from VW’s development portfolio.

The sole example of the multi-cog DCT? Destroyed, according to VW’s powertrain chief.

“Two months ago, I had the prototype crushed,” Friedrich Eichler told Automotive News at this year’s Vienna Motor Symposium.

At the time of its announcement, VW’s 10-speed was poised to become the world’s first automatic with a two-digit gear tally. Former development chief Hans-Jakob Neusser, who was later indicted by U.S. authorities for his alleged role in the diesel emissions scandal, claimed the new tranny would find a home in premium VW and Audi models. As a replacement for the company’s six-speed DCT, the new unit was said to be capable of handling up to 369 lb-ft of torque.

Ford and General Motors ultimately took the 10-speed crown for their jointly developed automatic transmission.

Why the change of heart? VW has moved beyond the “bigger is better” approach it took in the past, Eichler said. While he didn’t go into details, VW’s post-diesel scandal streamlining has seen the automaker’s focus on global sales replaced by an urgent need for profitability. Part of the cost-cutting includes reducing complexity in vehicle development and paring back on material costs — hardly a nurturing environment for the development of a big-ticket transmission.

Despite the sea-change at VW, the company’s powertrain boss isn’t ruling out the transmission’s return. “Of course, I saved all the data,” Eichler said.

"the new unit was said to be capable of handling up to 369 lb-ft of torque" That's it?! The old 5AT from Chrysler LX cars can handle 427.

  The infamous 01M 4-speed auto in my Jetta TDI couldn't handle the torque provided by the little 2ish liter diesel under the hood. As far ad I know, they replaced thousands of them under warranty (the gearboxes lasted 50k miles at best), and never updated the design or otherwise recognized the problem. Probably need to give VW a handicap on their gearbox torque ratings...

It seems that VW/Audi have a strange propensity for destroying unique things, things that might actually be interesting for future generations. Another thing they crushed that I can name off the top of my head were Racing Touaregs (save for a museum piece or two) after the program was shut.

3SpeedAutomatic 2012 Ford Escape V6 FWD at 147k miles:Just went thru a heavy maintenance cycle: full brake job with rotors and drums, replace top & bottom radiator hoses, radiator flush, transmission flush, replace valve cover gaskets (still leaks oil, but not as bad as before), & fan belt. Also, #4 fuel injector locked up. About $4.5k spread over 19 months. Sole means of transportation, so don't mind spending the money for reliability. Was going to replace prior to the above maintenance cycle, but COVID screwed up the market ( $4k markup over sticker including $400 for nitrogen in the tires), so bit the bullet. Now serious about replacing, but waiting for used and/or new car prices to fall a bit more. Have my eye on a particular SUV. Last I checked, had a $2.5k discount with great interest rate (better than my CU) for financing. Will keep on driving Escape as long as A/C works. 🚗🚗🚗
Rna65689660 For such a flat surface, why not get smoke tint, Rtint or Rvynil. Starts at $8. I used to use a company called Lamin-x, but I think they are gone. Has held up great.
Cprescott A cheaper golf cart will not make me more inclined to screw up my life. I can go 500 plus miles on a tank of gas with my 2016 ICE car that is paid off. I get two weeks out of a tank that takes from start to finish less than 10 minutes to refill. At no point with golf cart technology as we know it can they match what my ICE vehicle can do. Hell no. Absolutely never.

Jeff This is a step in the right direction with the Murano gaining a 9 speed automatic. Nissan could go a little further and offer a compact pickup and offer hybrids. VoGhost--Nissan has  laid out a new plan to electrify 16 of the 30 vehicles it produces by 2026, with the rest using internal combustion instead. For those of us in North America, the company says it plans to release seven new vehicles in the US and Canada, although it’s not clear how many of those will be some type of EV.Nissan says the US is getting “e-POWER and plug-in hybrid models” — each of those uses a mix of electricity and fuel for power. At the moment, the only all-electric EVs Nissan is producing are the  Ariya SUV and the  perhaps endangered (or  maybe not) Leaf.In 2021, Nissan said it would  make 23 electrified vehicles by 2030, and that 15 of those would be fully electric, rather than some form of hybrid vehicle. It’s hard to say if any of this is a step forward from that plan, because yes, 16 is bigger than 15, but Nissan doesn’t explicitly say how many of those 16 are all-battery, or indeed if any of them are.  https://www.theverge.com/2024/3/25/24111963/nissan-ev-plan-2026-solid-state-batteries
