Only available with the C30/S40/V50 2.0d in Europe for now.Geartronic are going down in favor of the double clutch powershift
Thanks, TexasV70R. Here's a clearer version of the press release:Volvo Cars launches Powershift - Two Transmissions in One
· Fully-automatic and sequential six-speed transmission
· Twin wet clutches give extremely fast and smooth changes
· About eight percent lower fuel consumption
· Optimised for powerful diesel enginesTwo-litre turbodiesel versions of the Volvo C30, S40 and V50 are now also available with a fully-automatic transmission. This new Powershift transmission is a six-speed unit. It features twin wet clutches that provide gearchanging comfort on a par with that of a fully-automatic transmission, yet with the performance one expects of a manual gearbox. What is more, it significantly cuts fuel consumption compared with a conventional automatic transmission.
The Powershift transmission has been developed by Volvo Cars in cooperation with its transmission partner Getrag. Powershift operates in principle as two parallel manual gearboxes. It has twin wet clutches that work independently of one another. One clutch controls the odd gears (1, 3, 5 and reverse) while the other handles the even ratios (2, 4 and 6). The two clutches operate alternately, with one engaging while the other disengages. This means that at the same time as the engine gets full power and maximum thrust in first gear, second gear is placed in readiness to be engaged. And when second gear has been engaged, third gear is readied, and so on. This promotes a continuous flood of power without any disruption in power delivery or any torque loss, resulting in extremely fast and silky-smooth gearchanges while maintaining acceleration throughout the gearchanging process.
Eight percent lower fuel consumption than a conventional automatic transmission
Apart from gearchanging comfort and high performance, Powershift contributes to noticeably lower fuel consumption.
"According to our measurements, Powershift contributes to a fuel consumption saving of about eight percent compared with a conventional automatic transmission," says Magnus Jonsson, Senior Vice President, Research & Development, Volvo Cars. "And that is an important benefit in the hunt to keep lowering the negative impact on the environment."
The Powershift function is based on the technology used in a manual gearbox but with the difference that the two wet clutches are each linked with their own input shaft. One shaft spins inside the other. The inner shaft regulates the output shaft for first, third, fifth and reverse gears, while the outer shaft controls second, fourth and sixth gears. The clutch function is operated by an electro-hydraulic control unit that ensures that one clutch is shut while the other is open, and vice versa.
Each clutch functions like a slip clutch. A piston pushes a number of clutch plates against each other and locks them together through the resultant friction.
Automatic or sequential gearchanging without any loss in torque
Powershift gives the driver an automatic transmission that permits sequential gearchanges, just like with Volvo's Geartronic transmission. The difference is that with Powershift even manual gearchanges take place without any time or power losses.
Since Powershift, unlike a conventional automatic transmission, does not need a torque converter, planetary gears or multiple wet clutches, there is also none of the added torque losses that these features bring.
Optimal choice for powerful diesel engines
Thanks to the use of twin wet clutches, the Powershift transmission can handle high torque levels and in principle has no limitations on choice of ratio. This makes it an ideal partner for today's modern, powerful diesel engines.
The version of Powershift that Volvo is now launching is dimensioned to handle torque levels up to 450 Nm. In the versions of the Volvo C30, S40 and V50 in which it is fitted, Powershift is mated to the 2-litre four-cylinder turbodiesel which delivers a power output of 136 hp and 320 Nm of torque.
"With Powershift we can now offer automatic transmission with our two-litre diesel engine," says Magnus Jonsson. "And it's not just any old automatic transmission: lower fuel consumption allied to increased comfort and higher performance sounds like an impossible equation. But with Powershift we have shown this is perfectly possible."

I want it for my C30 with the T5 since Volvo doesn't see fit to import the D5 to the States
This is indeed very good improvement compared to current auto transmission. Better fuel consumption, acceleration and comfort.Just can't wait when they will replace all the current autotrannies with PowerShift in every model. Or is there some reason that it would not happen ?
Even current D5 and V8 engines could use it, 400Nm and 440Nm, PowerShif can handle 450Nm.
I wonder if it will be possible some day to retrofit this gearbox to the XC90 T6, what an improvement that would be ! It would make al lot of T6 owners very happy I think.Just keep dreaming I suppose...

Dunno what is the lenght difference between current 6-speed autotranny vs. PowerShift gearbox....
There will be a second powershift for the SI6 that can handle 470nm.

My guess is that the upgraded 2009/2010 Euro V D5/2.4d will get powershift option.
Ban automatic transmissions, close drive-throughs, stop the obesity epidemic!I want three pedals on the floor and no cupholders please, before i even read further through the specs

Thanks to the use of twin wet clutches,
lolz
lololol
Just read that the Focus RS, which will have a turbocharged 5 cylinder engine that is rumored to have 300 HP and 295 ft-lbs of torque (sound familliar R owners?) will have this transmission.<<Fuels rumors of C30R>>
Volvo, get in gear for crissakes!!!!!
(punny!)
I fear that Volvo hasn't got the courage to build a C30 R.

In a heartbeat. Hell, I keep specking out at 34K so what's another 2K.I like hatches. I like hot hatches better. I could buy a bigger car but I prefer the C30.
Just dropping the powershift "dsg" would make the C30 much more competitive with the DSG-equipped Audi A3. So long as Volvo maps the clutch software properly to coordinate nicely with the engine, this would make the 227hp/236lb-ft engine really quite peppy in the C30.What about a C30 with a real T5 engine (the one out of the S60)? The T5 engine doesn't seem to be much more expensive than the regular 2.5T, and would give a boost to 257hp/258lb-ft.
Incidentally, why does the regular S60 2.5T engine still have 208hp/236lb-ft, instead of 227/236 these days? Trying to keep it differentiated from the T5? An S60 2.5T has, at least on paper, a pretty much identical torque band (kicking in properly at 1500rpm) and the same displacement as a C30's "T5".

Why does it have to cost that much? Marketing reasons? Is the R's engine THAT much more expensive than the T5 in the C30?
What does adding AWD to the S40 cost?What would it cost to make the same modifications to the current T5 being used in Focus ST.
The planned Focus RS has already been developed. How much would cost to add that running gear to a C30.
It seems that it wouldn't be too difficult to offer this same package on a C30.

As you know, Joe, an R model is not just the engine. It would include upgraded brakes, suspension, trim pieces, etc PLUS AWD.

The RS isn't going to be cheap either, but we aren't talking super car pricing either are we?I'd think that in the range of 36-40K would be appropriate. I don't think that Volvo wants a Halo car car, nor do I believe that beyond we Volvo faithful, there is any interest in such a car.

The S60R had a hard time selling in that price range.
A hatchback ain't gonna make it there.

The 300 HP Focus is NOT going to be AWD.
This I have to see.
I agree, though, but you don't need to full-boat R treatment on a model at that price point. Offer the Tec upholstery in a color not available to others, paint the stock gauges in another color, etc.
Keep it simple... no fancy adjustable suspension, just good tuning of steel springs. Powershift transmission. Etc. It could be done on the cheap but well IF Volvo had a brain in their head.
This is a step in the right direction.
Quote, originally posted by RearWheelPaul » This is a step in the right direction. Indeed. It is a much better alternative to the conventional slush box. Of course, that's what was said about the CVT, but so far the power limitations still remain. Not to mention the perception of "motorboating".
Some people I know have referred to CVT as a "snowmobile transmission" - though in a car it's a beefier design than the little drive belt setup on those things. The DSG Audi has been using in the A3 etc is, I think, a much different animal than the CVT - it's much more enthusiast-friendly. We'll have to wait to hear about people's real life driving experiences with the Ford Powershift system to see if it's similar to Audi's.

CVT feels like moped scooter, DSG feels like normal autotranny but with much more quicker shifts and less jerky.
