In June of that year, supplies increased to 3,000 per month, leading Subaru to make the CVT available in the [[Subaru Rex|Rex]] [[kei car]].<ref>{{cite journal|title=Fuji Heavy Industries to increase production of ECVT systems|date=13 June 1987 |page=12|journal=[[Nihon Keizai Shimbun]]}}</ref> Subaru has also supplied its CVTs to other manufacturers (e.g., the 1992 [[Nissan Micra]] and [[Fiat Uno]] and [[Fiat Panda|Panda]]).<ref name=Poulton>{{cite book|last=Poulton|first=M.L.|title=Fuel Efficient Car Technology |publisher=Computational Mechanics Publications|year=1997|isbn=978-1-85312-447-1|page=69}}</ref> Also in 1987, [[Ford Fiesta (second generation)|second-generation Ford Fiesta]] and [[Fiat Uno#Diesel and Selecta models|first-generation Fiat Uno]] were introduced with steel-belted CVTs, which are called CTX and Unomatic in Ford and Fiat, respectively. The 1996 [[Honda Civic (sixth generation)|sixth-generation Honda Civic]] introduced a pulley-based ''Honda Multi Matic'' (HMM) CVT which included a multi-plate clutch, not a [[torque converter]], to prevent [[idle creep]].<ref>{{cite web |url=http://world.honda.com/automobile-technology/CVT/|title=Honda Worldwide – Technology Picture Book – CVT |website=honda.com |access-date=19 October 2015}}</ref> Use of CVTs then spread in the following years to models including the 1998 [[Nissan Cube#First generation (1998–2002)|Nissan Cube]], 1999 [[Rover 200 / 25#Rover 25 (1999–2005)|Rover 25]] and 1999 [[Audi A6#C5 (Typ 4B, 1997–2004)|Audi A6]].<ref>{{cite web |title=Audi multitronic transmission |url=https://www.audiworld.com/news/99/multitronic/content.shtml |website=audiworld.com |access-date=10 July 2020}}</ref> The 1999 [[Nissan Cedric#Tenth generation Y34|Nissan Cedric (Y34)]] used a toroidal CVT—unlike the pulley-based designs used by other manufacturers—marketed as the ''Nissan Extroid'', which incorporated a torque converter. Nissan then switched from toroidal to pulley-based CVTs in 2003.<ref>{{cite web|url=http://www.nissan-global.com/EN/TECHNOLOGY/INTRODUCTION/DETAILS/CVT/|title=Nissan Technological Development Activities Overview: Xtronic Cvt |website=nissan-global.com |access-date=19 September 2009 |archive-url=https://archive.today/20120905095935/http://www.nissan-global.com/EN/TECHNOLOGY/INTRODUCTION/DETAILS/CVT/ |archive-date=5 September 2012|url-status=dead}}</ref> The version of the CVT used with the [[Nissan VQ engine#VQ35DE|VQ35DE]] engine in the [[Nissan Altima#Fourth generation (L32; 2007)|fourth-generation Nissan Altima]] is claimed to be capable of transmitting higher torque loads than other belt CVTs.<ref>{{Cite web |url=http://www.jatco.co.jp/ENGLISH/CVT/JF010E.html|publisher=Jatco|title=CVT|url-status=dead |archive-url=https://web.archive.org/web/20101204120037/http://www.jatco.co.jp/ENGLISH/CVT/JF010E.html |archive-date=4 December 2010}}</ref> The 2019 [[Toyota Corolla (E210)]] is available with a CVT assisted by a physical "launch gear" alongside the CVT pulley. At speeds of up to {{convert|25|mph|km/h|0|abbr=on|order=flip}}, the launch gear is used to increase acceleration and reduce stress on the CVT. Above this speed, the transmission switches over to the CVT.<ref>{{cite video |url=https://www.youtube.com/watch?v=TRtkPlKa8O8&t=3m8s | archive-url=https://ghostarchive.org/varchive/youtube/20211107/TRtkPlKa8O8| archive-date=2021-11-07 | url-status=live|via=YouTube |title=2019 Toyota Corolla Hatch: Top 5 Things You Need to Know! |quote=2019 Toyota Corolla Hatch: Top 5 Things You Need to Know!|access-date=29 December 2019 |date= 15 April 2018}}{{cbignore}}</ref> Marketing terms for CVTs include "Lineartronic" ([[Subaru]]), "Xtronic" ([[Jatco]], [[Nissan]], [[Renault]]), [[INVECS#INVECS-III|INVECS-III]] ([[Mitsubishi Motors|Mitsubishi]]), [[Multitronic]] ([[Volkswagen]], [[Audi]]), "Autotronic" ([[Mercedes-Benz]]) and "IVT" ([[Hyundai Motor Company|Hyundai]], [[Kia]]).
