Ricardo designed and built 7-speed DCT used by the 2005-2015 Bugatti Veyron, [1] [2] [7] [36] which has a turbocharged 16-cylinder engine producing 1,250 N⋅m (922 lbf⋅ft) of torque. Stellantis. Stellantis manufactures the electrified dual-clutch transmission (eDCT) at the Mirafiori Automotive Park in Italy as of 2024. Tremec
A cone CVT varies the drive ratio by moving a wheel or belt along the axis of one or more conical rollers. The simplest type of cone CVT, the single-cone version, uses a wheel that moves along the slope of the cone, creating variation between the narrow and wide diameters of the cone. Some cone CVT designs use two rollers.
The Shift Indicator reads P-R-N-D-Ds, Ds stands for Drive Sport, which doubles engine RPM. The CVT transmission proved unreliable after accumulating high mileage, causing Subaru to stop exporting cars with CVTs outside of Japan until the fifth generation Legacy/Outback. Subaru did continue to build Kei cars with CVTs, only for sale in Japan. In ...
Rated up to 23.5 kg⋅m (230 N⋅m; 170 lbf⋅ft) while having a dry weight of 79.9 kg (176.1 lb). It is contracted by Chrysler Group LLC for use in 2013–2016 Dodge Dart and 2014-2016 Jeep Compass and Jeep Patriot, the transmission is designed to be maintenance-free under normal use and is assembled in South Korea.

This design is also noteworthy because it preserves engine braking by eliminating a sprag between first and second gears. Instead of a sprag or roller clutch, Honda's older transmissions rely on pressure circuits to modulate line pressure to change gears. [3]
A continuously variable transmission (CVT) can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.
The design of most manual transmissions for cars is that gear ratios are selected by locking selected gear pairs to the output shaft inside the transmission. This is a fundamental difference compared with a typical hydraulic automatic transmission, which uses an epicyclic (planetary) design, and a hydraulic torque converter.
