The torque converter fits in the large round area.]] thumb|right|The same VTi transmission from the opposite side. The '''VTi''' is a continuously variable transmission for automobiles. It is fully-automatic, electronically controlled, and designed for transverse front-wheel-drive use. The ''VTi'' is assembled at a General Motors / Fiat joint venture plant in Szentgotthárd, Hungary.

Quality issues delayed the introduction of the VTi until the second quarter of 2002. Production ended in 2005.

The VTi can handle a maximum of {{cvt|200|Nm|lbft}} of torque for vehicles weighing up to {{cvt|2100|kg|lb}}, with gear ranges from 2.61 to 0.44. A 2.15 reverse gear is also specified. The effective final drive ratio is 4.35.

It uses two sets of 12 steel bands (Van Doorne belts) inside a die-cast aluminum casing. GM claims that the CVT's bands, normally a weak spot in CVTs, are reliable for at least {{cvt|100,000|mi|km}}. A {{cvt|225|mm|in}} torque converter is also used.

In 2004 GM extended the transmission's warranty on all 2002–2005 GM vehicles with the VTi to 5 years or {{convert|75,000|mi|km}}, due to high failure rates.

Applications: * 2002–2005 Saturn Vue (GMT315) * 2003–2004 Saturn Ion Quad Coupe * 2002–2004 Opel Vectra C (under the name CVTronic)
