[size=12.499999046325684px]Toyota used a Power Split Transmission (PST) in the 1997 Prius, and all subsequent Toyota and Lexus hybrids sold internationally continue to use the system (marketed under the Hybrid Synergy Drive name). The HSD is also referred to as an Electronically controlled Continuously variable Transmission. The PST allows either the electric motor or the internal combustion engine (ICE) or both to propel the vehicle. In ICE-only mode, part of the engine's power is mechanically coupled to the drivetrain, with the other part going through a generator and a motor. The amount of power being channeled through the electrical path determine the effective gear ratio. Toyota also offers a non-hybrid CVT called Multidrive for models such as Avensis. [size=12.499999046325684px]Audi has, since 2000, offered a chain-type CVT (multitronic) as an option on some of its larger-engine models, for example the A4 3.0 L V6. [size=12.499999046325684px]Fiat in 2000 offered a Cone-type CVT as an option on its hit model Fiat Punto (16v 80 PS ELX,Sporting) and Lancia Y (1.2 16V). [size=12.499999046325684px]BMW used a belt-drive CVT (manufactured by ZF Friedrichshafen) as an option for the low- and middle-range MINI in 2001, forsaking it only on the supercharged version of the car where the increased torque levels demanded a conventional automatic gearbox. The CVT could also be manually "shifted" if desired with software-simulated shift points. [size=12.499999046325684px]MG-Rover used an identical ZF CVT transmission on its Rover 45 and MG ZS models. [size=12.499999046325684px]GM introduced its version of CVT known as VTi in 2002. It was used in the Saturn Vue and Saturn Ion models. [size=12.499999046325684px]Ford introduced a chain-driven CVT known as the CFT30 in their 2005 Ford Freestyle, Ford Five Hundred and Mercury Montego. The transmission was designed in cooperation with German automotive supplier ZF Friedrichshafen and was produced in Batavia, Ohio at Batavia Transmissions LLC (a subsidiary of Ford Motor Company) until 22 March 2007. The Batavia plant also produced the belt-driven CFT23 CVT which went in the Ford Focus C-MAX. Ford also sold Escort and Orion models in Europe with CVTs in the 1980s and 1990s.
