Next VW GTI to get 10-speed dual-clutch gearbox



ollowing on Volkswagen's official announcement that it was working on a ten-speed, dual-clutch transmission, Auto Express has it on "good authority" that the new transmission will end up in the next GTI, GTD and Golf R. The brand's current seven-speed will be retained for lesser eight-generation Golfs.

While the new gearbox won't be limited to just the higher-end Golf range, the new hatchback, expected in 2017, will be the first to get it, Auto Express reports. The new DSG is the same size as the Volkswagen Group's seven-speed dual-clutch, and will easily fit into VAG's MQB platform, so we should expect it to filter into the rest of the Group's vehicles, much like the seven-speed 'box has.

The ten-speed is likely to see applications beyond even the small cars of the MQB platform. The gearbox can handle 405 pound-feet of torque, according to AE, making its application in larger offerings such as the gas-powered MLB cars and crossovers a likelihood.

Beyond the new gearbox, Volkswagen is also toying with mild-hybrid tech for the standard Golf and better batteries for the e-Golf. As we said, expect the new Golf to arrive in European markets in 2017, with the current Euro-market Golf getting updated next year. As for the US, we wouldn't be surprised if VW followed the trail blazed by the Mark 7, with a North American arrival for the eight-gem Golf slated for a year or so after sales in Europe begin.

That's far too many gears in a manually controlled gearbox.

Hopefully they get the ratios right. 6th gear in my wife's Rabbit is useless on anything but level ground below 70 MPH. This sounds like a disaster in the making though.

It is actually has 10+2 gears. It has an overdrive and one crawl gear, those can not be used with maximum torque so VW does not count them as two full gears.

Why not just CVT?  With 10 +2 gears, sooner or later, the thing will get confused and spew its guts all over the road.

I agree. Putting money into improving CVT efficiency would be better than developing 60 speeds.

FIA banned them in F1

I am not sure I want CVT in a performance car. Line has to be drawn somewhere.

Yeah having the engine continuously at peak torque/HP is terrible

Peak HP *

That's where you want to sit

VW's are teh sux anyways so who cares if they just get more suck?

[Galaxy]

What?

The lowest and highest gear ratios (1st and 12th gear if you will) are torque limited.

AKA parking lots and freeway cruising.

Have you driven a CVT equipped car? It IS terrible.

They've only been used in economy cars so far.

Perfect in theory. Very far from perfect in car. Snowmobiles are okay, though. They drive more like jet skis, anyway. So much drag that power interruptions to shift will not work very well. A DCT may work well, but who needs 20 speeds in anything other than a huge semi truck?

No. I have driven a terrible Saturn Vue with a CVT, and it seems like every Nissan model has one.

I'm guessing it probably has 3 or 4 overdrive gears (the Corvette's 7MT has 3).  And why would they need to limit torque on an overdrive gear?  Taller the gear, the lower the stress on the driveline (less torque multiplication).  I can understand limiting torque on shorter ratios, if only to reduce torque steer (Mazdaspeed3 did this).

Nissan has some in the Maxima/Murano.

It has to do with the flow of energy. The 10+2 speed only has one more cogwheel then the 7 speed, the big change is how the power gets shuffled around. 10 intreconnections are stable, 2 are not entirely, so are not counted as full gears.

No- I was gonna say, I think the ideal ratio of gears for a performance car is 7, maybe 8. 1st 6 or 7 for performance, last one for fuel economy. GTI isn't fast enough to warrant all those damn gears. If they can get gears 1-5 right I guess it doesn't really matter.

[SVT666]

I think 6 gears is ideal in a manual. My Infiniti has a 7 speed auto and that's fine, but I'm not rowing my own in that car. But when I'm using the paddles, 7 is starting to push it when it comes to knowing what gear you're in without having to look at the display.  Even with a DCT, 10 gears is too much.

[12,000 RPM]

Sometimes I feel like my Z could use a 7th gear.

For a 4 cylinder car IMO 5 speeds is perfect.

Torque limit in a super OD gear I'm guessing is to limit lugging the engine for extended periods (which is bad on engine bearings).

[Galaxy]

Stupid.

Not really. This 10+2 has the same exterior dimensions as the 7 speed DSG, and weighs only 5kg (11lbs) more.

Yeah, and the last gear needs to be super tall. Unlike rally accent.
