The Audi Q5 will reportedly make its official debut at the Bejing Motor Show next month and with Porsche's increased stake in the Volkswagen group – going from 31-percent to more than 50-percent – that means that VAG and Porsche might begin to finally play nice again with platform sharing.

Initially, the new Q5 was supposed to underpin Porsche's own mini 'ute, but rumors suggested that Audi's board nixed the idea for fear that a Porsche model sharing the same platform could steal sales from the new CUV. That's about to change as Porsche gets a few seats on VAG's board, and according to Autoweek, development of the vehicle-formerly-known as the Roxster is back in full swing.

While there's no new information about the Porsche, Audi's Q5 will be revealed packing the new seven-speed dual-clutch S-tronic gearbox mated to a longitudinal engine. The real benefit of the new DL500 transmission is that it can handle torque output up to 405 lb.-ft. and engine revs of 8,500 rpm. The new tranny will disseminate throughout the rest of the Audi lineup in coming years, first in Quattro models, including the new A4, and then on down to the automaker's front-wheel-drive models.

Construction of the $530 million dollar plant being built by Chrysler and Getrag in Kokomo, Indiana, has been suspended indefinitely due to a contract dispute between the two companies. Neither Chrysler nor Getrag were willing to specify the exact reason for the stoppage, the only word from Chrysler to Automotive News was that it hopes the dispute can be resolved so that the transmissions will be available in mid-2009. We hope so too, since the new dual-clutch transmissions are an integral part of Chrysler's powertrain revamp which includes the new Phoenix V6.

Volkswagen's dual-clutch gearbox (DSG) has proven that a balance can be struck between driver involvement and running the daily slog without a cramped left leg, with a bump in fuel economy to boot. As reported earlier this year, VW has plans to introduce another cog onto its six-speed DSG unit, while at the same time dropping the wet clutch arrangement for a dry-clutch setup. Now it's official: the new seven-speed DSG not only boasts another gear and dry clutches, but it's the first time the DSG transmission is able to be mounted for a front-traverse setup.

The seven-speed 'box will originally be available on the Golf and Golf Plus models abroad, equipped with the 1.4-liter TSI engine and 1.9-liter TDI mill, and the 1,750 euro premium over the base model also includes a hill-start assist system. The next generation, Borg-Warner-developed DSG has the capacity to channel 184 lb.-ft. of torque to the wheels, which should suit both models well, but it will need some beefing up before it becomes standard on more performance-oriented models.

The dual-clutch gearbox was originally conceived back in the 1930s by half-track inventor Adolphe Kégresse, but its first practical application didn't appear until nearly six decades later in the back end of some Porsche 956 and 962 race cars and some Audi rally cars. For whatever reason, Porsche dropped the idea in favor manually shifted automatic TipTronic gearboxes for its production cars.

Volkswagen finally brought the dual clutch system to the masses a few years ago with its DSG units. It looks like Porsche will soon finally add the setup to its road cars in the next few years with the brand name it used on the race cars – PDK for Porsche Doppel Kupplungen or Porsche Double Clutches. The TipTronic paddle shifters will be retained so that the driver can execute shifts without releasing the steering wheel. No word yet on timing or application, but as soon as we know you will.

Whatever stance you take in the automatic versus manual debate, if you haven't done so already, go out and sample a VW or Audi product equipped with the DSG transmission. All the positives – quicker shifts, better fuel economy, geek-cred – far outweigh the negatives and the fact that Porsche, BMW and even Chrysler are looking to develop their own dual-clutch gearbox, should tell you that DSGs are here to stay. Add to the fact that they may also be cheaper to produce and service, it didn't take anymore convincing for Ford and its Swedish arm, Volvo, to decide that they better throw their hat into the game.

WhatCar is reporting that a DSG-like tranny will find its way into Volvo models within the next two years and rumor has it that a high-performance version of the C30 will be one of the first vehicles to come equipped with the new gearbox.

In addition to Volvo's use of the dual-clutch setup, expect to see it carry over into Ford's vehicles as well, much like the migration from slush boxes that VW is in the process of executing.

The dual-clutch gearbox's popularity has grown immensely over the past three years and that popularity only stands to grow. Average motorists have enjoyed the DSG's smooth shifting and economical fuel consumption, while enthusiasts appreciate the trick technology and uber-quick gear changes. Volkswagen already announced that they plan on replacing all their automatic transmission vehicles with DSG in the next five years and here's a stat for you -- half of all GTIs sold are equipped with paddle shifters.

DaimlerChrysler has recognized the benefits of the DSG over conventional, torque converter-equipped automatics and has decided to invest $560 million in a new assembly plant in Kokomo, Indiana to manufacturer their own version of the DSG. Partnering with Getrag, the automaker plans on creating 700,000 units annually, with production set to begin in 2009. The models that stand to benefit from the new transmission are primarily front-wheel drive vehicles, including the Avenger, Sebring and all manner of minivan. Additionally, the transmission will find an ideal partner with D.C.'s new Phoenix V6 engine, which will also make an appearance in 2010.

Industry analysts recognize that the greatest source of competition with DSGs are the continuously variable transmissions (CVTs), but one expert cited in Automotive News expects that the number of DSG-equipped vehicles in the U.S. will rise from it's current 0.2-percent to 3.3-percent by 2012. The more the merrier in our eyes.

The Bosch Group and the Getrag Group announced Tuesday that they will partner to develop and market parallel hybrid systems to provide a near-turnkey hybrid solution to automakers.

In a parallel hybrid solution, the electric motor is fitted directly into the power flow of the drivetrain. Under the terms of the partnership, Bosch will handle the electrical systems and power electronics, while Getrag will supply its dual-clutch transmission technology. The companies plan to jointly develop final-drive units with directly integrated electric motors. Bosch already has subsystems off the shelf for hybrid powertrains, and is well advanced in developing electric motors that can be directly integrated into a vehicle's powertrain (as shown in the cutaway model at right).

Once off the shelf hybrid systems are available, we can expect even small automakers to be able to offer hybrid models without prohibitively time-consuming and expensive product development. Bosch and Getrag estimate that their hybrid systems will allow automakers to realize fuel savings of up to 20 percent (using the European fuel economy test cycle) over gasoline-only drive systems.

The Getrag Group is the world's largest independent transmission manufacturer in the world, while Bosch is the world's largest auto parts supplier.
