The 7-speed dual clutch transmission makes especially sporty driving performance possible: direct drive and lightning-fast gear changes without interrupting the shear force. The car 'sits right on the gas'. It also achieves fuel economy better than that of a manual transmission thanks to its excellent fuel efficiency. Mercedes-AMG developed the 7-speed MCT 'Multi Clutch Technology' planetary automatic transmission. The MCT transmission is essentially the 7G-Tronic automatic transmission without a torque converter. Instead of a torque converter, it uses a compact wet startup clutch to launch the car from a stop and also supports computer-controlled double. 7-Speed Dual-Clutch Transmission with High Performance and Dynamics The 7DCI700 seven-speed transmission was developed for performance vehicles and sports cars with inline installation. The shortened response times during the gearshift allow for greater driving pleasure and provide a more direct driving experience. Ford has added a new seven-speed dual-clutch automatic transmission option to the Fiesta and Puma models in Europe, offered in combination with the mild-hybrid 1.0-liter EcoBoost engine.

The heart of Shelby GT500 performance begins with a 700-plus-horsepower5.2-liter supercharged V8 engine. It’s mated to an ultra-fast TREMEC 7-speeddual-clutch transmission and calibrated by Ford Performance withstate-of-the-art drive mode technologies. As the most powerful productionMustang ever, the Shelby GT500 powertrain is the primary enabler for theultimate performance that follows.

When it arrives this fall, the most powerful street-legal Ford vehiclein history is projected to post mid-three-second 0-60 mph times andsub-11-second quarter-mile times for the quickest acceleration ever in aroad-going Mustang.

A hand-built double-overhead-cam engine shares the aluminum block, boreand stroke of the Shelby GT350’s, adding block and head structure, improved oiland cooling capacity, plus a cross-plane crank to support its higherhorsepower.

Helping to deliver more than 700 horsepower is a 2.65-liter supercharger.A unique roots-type compressor features an inverted design with charged airoutput at the top for more compact packaging – one that allows for a largerair-to-liquid intercooler for consistent track performance.

“With its supercar-level powertrain, the all-new Shelby GT500 takes thesixth-generation Mustang to a performance level once reserved only forexotics,” said Hermann Salenbauch, global director, Ford Performance vehicleprograms. “As a Mustang, it has to be attainable and punch above its weight. Tothat end, we’ve set a new standard among American performance cars with ourmost powerful street-legal V8 engine to date, plus the quickest-shiftingtransmission ever in a Mustang for all-out precision and speed.”

For enthusiasts who demand performance at the highest levels, automated manual transmissions are the domain of exotic supercars. Capable of shift transitions in less than one-tenth of a second, markedly faster than any manual gearbox, Shelby GT500’s computer-controlled TREMEC 7-speed dual-clutch transmission delivers the best of both worlds – high power and torque transfer plus smart powertrain controls. With this dual-clutch transmission, a whole new world of performance is at your fingertips – full automatic, semi-automatic paddle shift mode and full manual paddle shift.

In each mode, the new dual-clutch transmissionmarkedly outperforms even the most skilled manual transmission drivers in everyenvironment – street, drag strip or track. Leveraging years of racing andperformance engine development, Shelby GT500 brings some of the industry’s bestdrive mode technologies to the car’s Track Apps that tick off seconds andcapture driving data.

To channel power and torque to the unique carbonfiber driveshaft, Ford Performance leveraged learnings from the tuning of itsFord GT supercar’s dual-clutch transmission and selected the TREMEC® 7-speeddual-clutch transmission. This dual-clutch transmission is designed for anumber of drive modes, including normal, weather, sport, drag and track, andactivates features like line-lock and launch control through selectable TrackApps.

“This is a watershed moment for us at TREMEC,” said Matt Memmer, TREMEC engineering director. “All systems and subsystems – including hardware such as low leak solenoids, to control systems and software to optimize the performance of the system – were internally developed for maximum performance.”

Featuring twin clutches thatengage and release in perfect computer-controlled synchronization, the TREMEC DCTcan transition from gear to gear with either imperceptible limousine-likeshifts or the ferocity of an F1 machine. “Our virtually dry clutch design marries the benefits of wet and dry clutchtechnologies into a hybrid design,” explains Antonio Herrera, TREMEC’s managingdirector. “The result is shifts that areflawlessly tailored to the Shelby’s performance modes and respond brilliantlyto inputs from the driver.” Working sideby side with Ford engineers, the TR-9070 integrates into the Shelby powertrainin a way that must experience to be appreciated.

The all new TREMEC DCT combines TREMEC’s years of experience inperformance transmissions with cutting-edge design mechatronics and software tomake the GT500 the most powerful Mustang ever built. “This new transmissionrepresents a massive investment in terms of both dollars and man hours,”commented global business development director, Dave Hadley. “However theresults have proven well worth the effort. The DCT is a masterpiece intransmission design and we’re honored to have played an instrumental role inFord’s new Shelby GT500 program.”

On the dawn of its 55th anniversary, TREMEC rocksthe muscle car ecosphere with the release of its all-new 7-speed DCT!

The Mercedes-AMG GT is a spectacular performance car that takes Mercedes AMG’s Formula 1 expertise and applies it to the world of road cars. Harnessing the power of the handcrafted turbo charged V8, the AMG Speedshift DCT 7 transmission is as close to F1 technology as we can get in a road car.

The 7 speed, dual-clutch transmission has been developed for the Mercedes-AMG GT by German supplier Magna PT (formerly Getrag). It has been used in supercars such as the SLS AMG, Ferrari California, the popular 458 Italia, the F12 Berlinetta and the second-generation Ford GT.
In the Mercedes-AMG GT, the transmission is placed in a rear transaxle configuration, serving as the car’s transmission, rear differential, and rear-axle, all in a single assembly.
Connecting this assembly to the V8 engine in a single, fixed unit is done with the use of a torque tube. Inside, a carbon fiber drive shaft spins at the same speed as the engine.
At only 8.6 pounds (3.9 kilograms), the torque tube is similar in weight and structural design as the drive shaft on race cars. The transmission is also fitted with a centrifugal pendulum placed into the two-mass flywheel that eliminates oscillations and vibrations.
Due to this configuration and the technologies it uses, the car achieves an ideal 47% front and 53% rear weight distribution which dramatically improves the car stability and handling.
This marvelous feat of engineering functions as two transmissions built into one, each equipped with an electronically controlled clutch. One of the transmissions engages and disengages the odd numbered gears and the other does the same with the even numbered gears.
Since the gear sets are independent the control system can pre-engage the next gear, prior to the shift. For example, if the car is driving in fourth gear, the fifth is pre-engaged.
The upshift occurs in less than 100 milliseconds after interacting with the paddle shifter, when one clutch disengages and the other engages.
To achieve reverse gear without the use of an added shaft that would have created extra weight and extend the overall design of the transmission, the Speedshift DCT 7 intelligently engages a combination of gears two, reverse, thee and one. With the use of all available shafts, the car can be maneuvered backwards.
The first gear has a higher ratio on the AMG GT while the seventh gear and the final drive gave lower ratios. This helps achieve a very spontaneous and agile acceleration, supplies instant response to gas pedal movements, and offers increased shift performance and response time.
There are three pre-installed drive programs to enjoy on standard AMG GTs: 'C' (Comfort), 'S' (Sport), 'S+' (Sport Plus). A fourth “I” (Individual), customizable program is also available.
The high-end models like the AMG GT S, GT C and AMG GT R also have a “RACE” drive program available, which adapts shifting dynamics of the dual-clutch transmission to the requirements of a racetrack.
The AMG Speedshift DCT 7G is still one of the quickest, most agile transmission ever made and although the German constructor, Magna PT has shifted focus on the development of the eight-speed dual-clutch transmission 8DCL900, it will remain a timeless piece of automotive technology in cars such as the Mercedes-AMG GT.
